Welded pressure tube · Multipart EN series
A welded pressure tube is routed to its part by two things: the weld process it is made by and the material family it is made from. Everything else — the temperature duty, the test category, the documentation — is an order input confirmed against that part. Set the selecting inputs and the routing table narrows to the part that describes what you are buying.
Price on request. EN 10217 covers the welded route — the seamless equivalent is EN 10216, a separate standard and not a substitute. No pressure rating or wall thickness follows from the part number; those come from your design calculation.
Weld process
Resistance, fusion or submerged arc — the series separates parts by it.
Material type
Non-alloy, alloy or stainless — a part is written for a family.
Temperature duty
An order input confirmed against the part, not a part selector.
Test category
Your project picks it; the framework offers the options.
EN 10217 welded part routing
Two of these four inputs select the part — the weld process and the material family. The other two, the temperature duty and the test category, are order inputs you confirm against the part rather than filters that pick it. Keeping those two roles apart is what makes the routing honest.
Weld processSelects part
The welding process the tube is made by — the series separates parts by process, so this is a selecting input.
Material typeSelects part
The material family the relevant part addresses — non-alloy, alloy or stainless. Parts are written for a family, not for the whole range.
Temperature serviceOrder input
The duty your design sits at. This is an order input confirmed against the part — the parts are not selected on it alone.
Test categoryOrder input
The inspection and test category the order requires. The framework offers options; your project picks one — this is an order input, not a part selector.
5 of 5 welded parts match that weld form
Resistance / induction welded, non-alloy
A resistance-welded non-alloy part — A part of the series written for tube welded by electric resistance or induction from a non-alloy material. The seam is formed without added filler, and the delivery condition is set around that welded product form.
Resistance-welded is a defined process — the part does not cover tube welded with filler added, which is addressed by a different part.
Fusion welded with filler, non-alloy
A fusion-welded non-alloy part — A part written for tube welded by a fusion process with filler added, from a non-alloy material. The welding process, and the way the seam is made, is what places the tube here.
Fusion welding with filler is a separate product form from resistance welding — the parts do not stand in for one another.
Fusion welded with filler, alloy
A fusion-welded alloy part — A part for tube fusion-welded with filler from an alloy material. Both the process and the material family differ from the non-alloy fusion part, so the delivery condition is written differently.
The alloy family is addressed separately from non-alloy — a familiarity with the process does not carry the material across.
Submerged arc welded
A submerged-arc welded part — A part written for tube made by the submerged arc process, which is used on larger-diameter welded tube. The process itself is the selecting characteristic here.
Submerged arc is its own process in the series — it is not an interchangeable label for resistance or fusion welding.
Stainless welded tube
A stainless welded part — A part written for welded tube in a stainless material family, where the material is selected for corrosion resistance alongside the pressure duty. Stainless is addressed by its own part of the series.
Stainless is not covered by the non-alloy or alloy parts — an austenitic requirement does not fall under them, whatever the weld process.

Supplier: Noor Deira Steel Trading L.L.C. — sales@noordeirasteel.ae — +971 56 398 0860The table routes by published scope — it does not certify a part for your duty. Which part your design basis requires is settled by the governing edition read with your project specification; whether the welded tube is acceptable under your design code is a separate check owned by your engineering team. Use the routing to see which part describes what you are buying, then confirm it against the standard itself.
What the series governs
A welded tube carries a seam, and the series is built around that: the welding process and the material family are what separate one part from another. Read the series as a single standard and the parts collapse into an assumption the certificate cannot later correct.
Inside the series
Outside it — and often assumed
Why the part matters more on a welded tube
On a seamless tube the manufacturing route is one thing — the tube is formed without a seam, and the parts divide mainly by material and service. A welded tube adds a second variable that runs through everything: how the seam is made. Resistance welding, fusion welding with filler and submerged arc are different processes producing different welded product forms, and the series separates them for that reason. Naming only the series on the order leaves the process unnamed, and the process is a large part of what you are buying.
That is why the routing table treats the weld process and the material family as selecting inputs and everything else as order-level. The temperature duty and the test category are real requirements — they are simply requirements that are confirmed against a part rather than used to choose one. Keeping those roles separate is what stops a requisition from quietly assuming that any welded part will do.
Part scopes on this page are stated by weld process and material family only. We publish no grade lists, temperature figures, pressure values or test-clause numbers — those follow the governing edition of the applicable part and are confirmed against the requirement you state.
Where EN 10217 stops
EN 10217 and EN 10216 sit either side of one question: how the tube is made. Reading them together is genuinely useful — it is how an engineer decides whether the welded route is right for a duty. Reading one as a stand-in for the other is the mistake this section exists to close.
EN 10217 — this page
The welded series for pressure purposes. The tube carries a seam, and the parts separate by that weld process and by the material family. If your design basis names a welded tube, the applicable part is drawn from this series.
EN 10216 — the seamless counterpart
The seamless series for pressure purposes. It is the natural comparison when you are deciding which route a duty actually needs, and it is a separate standard with its own parts. It is not an alternative supply of the same thing — the manufacturing route is written into the delivery condition and shown on the certificate.
EN 10216 seamless pressure tube
How to use the comparison without abusing it
A comparison is a decision aid, not a supply instruction. Use it upstream — when the design is still open, to establish whether the welded route suits the duty, the dimensions and the service. Once the design basis names a standard, that standard is what the order carries, and the welded-to-seamless question has already been answered by someone with the engineering responsibility for it.
What we will not do is quietly fill a seamless line with welded tube, or the reverse, because one happened to be available. Both routes are legitimate; they are simply different products. Tell us the route your design requires and we quote against it.
No equivalence between EN 10217 and EN 10216 is implied anywhere on this page. Any change of manufacturing route is an engineering decision for your design authority, and it must reach us as the standard you now want.
Order-specific fields
The series provides the framework; the order-specific fields turn a generic request into a deliverable. On a welded tube there are more of them than on a seamless one, because the weld process joins the list — and each field is something the certificate has to reflect.
The weld process
Resistance, fusion with filler, or submerged arc — named on the order, because the series separates parts by it and the certificate describes the seam.
The material grade and family
The grade within the applicable part, and the family it belongs to. The part sets the framework; the grade is yours to name.
Dimensions and wall convention
Outside diameter, wall thickness and length, with the convention understood — these feed the design calculation, they do not replace it.
The temperature service
The duty the tube is for, confirmed against the part rather than used to select it. Your design basis holds this figure.
Test category and inspection
The inspection and test category the order requires, stated rather than assumed. The framework offers the options; your project picks one.
Documentation the order must carry
The records your project expects to receive — agreed at order placement, because an assumed set cannot be added after delivery.
A reasonable fit when
Revisit the basis when
Getting the dimensions onto the order
The dimensions the order carries are an input to the design calculation, not an output of it, so they have to be stated clearly and read the same way on both sides. The steel pipe dimensions reference sets out how the size and wall are described, and the steel pipe weight chart supports the tonnage side of a welded-tube enquiry — useful when a large-diameter order is being planned rather than a single length specified.
The materials behind the welded parts
The welded parts sit within the wider steel pipe supply range, and the grade designations the parts refer to are gathered in the EN steel grades reference — worth reading when the grade itself is still being settled, before the part is fixed.
The material reference covers the grade; the standard reference covers what the tube must be.
GCC markets
An EN-spec requirement is often raised on a project inside the Gulf, where the design basis is European but the delivery is local. Destination changes the commercial and documentary side of the order, not the acceptance basis.
The hub for the other pipe specifications, including the EN series split by welded and seamless. If the standard is still being chosen, settle it against your design basis before the tube is ordered.
Project coordination and release documents.
Confirm the part, weld process, grade, dimensions, test category and documentation against the project requirement, then plan release to site, fabricator or stockist.
Specification alignment and import papers.
State the applicable part, governing edition, design code and ordered inspection alongside the delivery base so the offer matches the requirement.
Requirement and delivery window.
Confirm dimensions, wall convention, quantity and delivery window so the documentation plan stays aligned to the order.
Delivery basis and documentation.
Give the delivery point and Incoterm so the certificate and release paperwork can be arranged against the order.

These market pages are procurement destinations, not a claim of premises in each country. Supply is coordinated from Dubai and delivered against the destination and delivery date you state.
Compare and verify
A welded pressure-tube requirement is frequently raised where a seamless, US-spec or general-service one was meant, and the neighbouring references carry the decision either way. These are the pages worth checking before the part is fixed.

Comparing across parts and standards
A designation from one part is not an interchangeable part for a designation in another, and within the series the parts are not tiers of one product — they are separate delivery conditions reached for on separate grounds. Moving between them changes the weld process or the material family, and with it the inspection and the certificate expectations, so it has to be re-confirmed against your design basis rather than carried across from a designation on an old requisition.
Where the requirement is a steel tube rather than a pipe, or the manufacturing route is still open, check the product form first — the standard and the delivery condition change with it, and so does what the certificate has to demonstrate.
Read the governing part
The grades a part covers, its weld processes, its delivery conditions and its inspection provisions all sit inside that part of the standard. Read the applicable part alongside your project specification and your design code rather than relying on the series name alone — the documents answer different questions, and the part only answers its own.
An EN-spec requirement is often raised on a project inside the Gulf, where the design basis is European but the delivery is local — the UAE market page sets out how project coordination and release documents are handled locally, worth reading before you fix the delivery basis.
From routing to offer
The routing settles which part describes what you are buying; the order fields settle what the tube must be within it. This is the sequence that turns that into a comparable offer, and the point at which each input is actually used.
Manufacturing route fixed
Design authority
The design basis names a welded tube, so the EN 10217 series applies rather than the seamless one.
A seamless requirement points to EN 10216 — a separate standard, compared but never substituted.

The weld process the tube is made by is named — resistance, fusion or submerged arc.
The series separates parts by process; without it the part cannot be fixed.

Request a QuoteStraight answers
These are the ones the desk fields most often from EU-spec engineers sourcing welded pressure tube, answered the way they are answered there — including the parts that make the process slower.
The weld process is one of the two inputs that select the part, not the only one — the material family is the other, and both must be named before the part is fixed. Resistance welding and fusion welding lead to different parts; a non-alloy and an alloy requirement lead to different parts even at the same process. That is why the routing asks for both. A requisition that names the process but not the material, or the material but not the process, has left the part open — and the part is where the delivery condition lives.
Not as a supply decision. EN 10216 covers seamless tubes and EN 10217 covers the welded equivalent — two standards for two manufacturing routes, and the route is written into the delivery condition and shown on the certificate. Whether the route may change is an engineering question for your design authority, not a procurement one. If a seamless option is genuinely acceptable to your design, that decision should reach us as the standard you now want. We quote the route your specification names rather than substituting the more convenient one.
No — and this is the assumption the multipart structure exists to prevent. No single part spans all steels, all weld processes and all services; each part is written for a defined combination of weld form and material family. The temperature duty and the test category sit on top of that as order inputs, confirmed against the part rather than widening it. So there is no part that covers everything, and the question is never 'which part is broadest' but 'which part describes what I am buying'.
No. EN 10217 names the welded series; the part names the weld form and material family the tube belongs to, and the order fields name the grade, dimensions, test category and documentation. An offer that stops at the series name has left all of those to assumption, and two suppliers can both quote 'EN 10217' while describing different welded products. When you compare quotations, compare the full designation — series, part, weld process and grade. If an offer does not state the part and the process, they have not been fixed.
The test or inspection category is one of the order-specific fields, and it is yours to state rather than ours to choose — the framework offers the options and your project selects the one your service requires. On a welded tube the examination of the seam is a significant part of that, which is why the order fields are listed explicitly rather than read off a table. Tell us the category and the documentation your project expects to receive, and the desk confirms the offer against them rather than assuming a default.
We do not publish stock positions on this page, because a figure written here would be stale by the time it mattered, and availability varies with part, weld process, grade, dimensions and inspection category. It is confirmed against your stated basis, quantity and required date when the enquiry reaches the desk. That is the honest sequence — the answer you plan around is the one given for your order.
Frequently asked questions
Five questions EU-spec engineers raise most often, answered without deferring the technical position to the quotation stage.
It is a multipart series, and the part is the first thing to fix. EN 10217 is the umbrella for welded steel tubes for pressure purposes, divided into parts that each address a different combination of weld process, material type and service. The parts share a general shape but they are separate technical delivery conditions — not editions of one another and not interchangeable. A purchase order that says only 'EN 10217' names the series and leaves the part, where the actual requirement lives, unstated.
The part follows from the welding process you are ordering and the service the tube must meet — the series is organised so that each part covers a defined combination of process, material type and temperature duty. So the decision is not which part is 'best' but which part describes what you are buying: a particular welded product form, in a particular material, for a particular service. Settle the weld process and the service conditions from your design basis first, and the applicable part follows from them rather than from a supplier's preference.
Not as a supply decision. EN 10216 covers seamless tubes and EN 10217 covers the welded equivalent — two standards for two manufacturing routes, and the route is written into the delivery condition and reflected on the certificate. Whether the route may change is an engineering question that belongs to your design authority, not to procurement. If a seamless option is genuinely acceptable to your design, that is a decision made on the engineering merits and it reaches us as the standard you now want. We quote the standard your specification names.
More than the series name, because the series is multipart and welded. The order has to identify the applicable part, the weld process, the material type and grade within the part, the dimensions and wall convention, the test category the order requires, and the documentation it must carry. The specification provides the framework; the order-specific fields are what make your order a distinct deliverable rather than a generic request. Naming them is how the offer you accept and the certificate that arrives describe the same tube.
No, and no table on a supplier's page can substitute for it. The standard governs the technical delivery conditions — what the welded tube is made of, how it is welded, how it is delivered and how it is tested — within a multipart framework. The allowable pressure and the wall thickness for your duty come from a pressure-design calculation using the dimensions, the design temperature and the design code your project follows. The part you order and the design calculation are two different documents doing two different jobs.
