ASTM B862 welded titanium pipe is formed from flat-rolled titanium and joined along a seam. The purchase is therefore controlled by more than grade and diameter: strip/plate identity, forming route, seam process, heat treatment, weld examination, dimensions and pressure acceptance belong on the same order. Five company-owned pages met the rule.
How the five company sources were selected
We froze the query ASTM B862 welded titanium pipe supplier manufacturer on 1 September 2026. Eligible sources were company-owned pages expressly offering welded titanium pipe under B862 or a clearly described rolled/welded route and exposing dimensions, grades, seam process, NDE, testing or fabrication fields. Beiyu, geographies excluded by site policy, marketplaces, directories, third-party lists, seamless-only pages and B338 heat-exchanger-tube-only pages were removed. Discovery order is not a quality ranking.
A public page can identify a likely supply route. It cannot prove allocated stock, a current program approval, final schedule, lot compliance or suitability of material/equipment not yet produced or assigned. Those points remain dated quotation fields.
Company pages that met the rule
| Company source | Page role | Visible fields | RFQ check |
|---|---|---|---|
| TiFab | Pipe and spool fabrication page | B862/B265 rolled-and-welded route, 6 to 96 inch range, RT/PT and optional final hydrotest | Separate mill pipe from fabricated spool and state NDE, hydrotest, grade and drawing |
| Jucheng Titanium | Welded-pipe product page | Grades 1/2/5/7/9/12, OD/wall/length, automatic-welded route, annealed state and NDE options | Return exact process, heat treatment, seam examination, edition and dimensional report |
| Reliab Metal | B862 welded-pipe page | Grade 1/2/3, coil/strip forming, laser welding, heat treatment and eddy-current/UT/airtightness sequence | Confirm pipe designation, grade, tolerance basis and ordered tests |
| Seather Technology | Large welded pipe/tube page | 90 to 5000 mm OD, long lengths, single seam, stated 100% RT/PT, MTC and TPI options | Verify that the stated inspection applies to the offered size, grade and seam |
| Baoji Gloritime Titanium | Welded/seamless pipe family | Large-diameter welded range, grades 2/7/12 and X-ray inspection claim | Require a B862 welded route; do not mix B338 tube or B861 seamless acceptance |
Several pages combine pipe, tube, spool and rolled cylinder language. These are different deliverables. Hold the B862 welded-pipe line, finished dimensional convention and seam acceptance constant; then identify whether cutting, elbows/flanges, field-fit allowance, supports and final system hydrotest are outside or inside the supplier’s scope.
Put the weld seam on the purchase order
| Decision | Choices visible in the source set | Required written return |
|---|---|---|
| Product identity | ASTM B862 welded pipe versus B861 seamless pipe, B338 tube or fabricated spool | Exact product standard/edition, grade and deliverable boundary |
| Starting material | B265 strip/plate heat, width/thickness and surface/condition | Heat/lot link from flat product through every finished pipe length |
| Seam route | Automatic GTAW/PAW/laser or offered qualified process; filler/no filler | WPS/PQR boundary, shielding/cleanliness, seam count and heat treatment |
| Dimensions/ends | OD or NPS/schedule, wall, length, ovality, straightness and bevel | Finished measured report, tolerances and fit-up/end protection |
| Acceptance | Visual, PT, RT/UT/ET, leak/hydro, mechanicals and supplementary tests | Extent, method, standard, criteria, repairs and signed records |
Do not copy an NDE percentage from a public page into the purchase order without identifying the method, acceptance standard and coverage. A claim of 100% X-ray may refer to one product family, diameter band or fabrication route. State whether radiography covers the longitudinal seam only, how start/stop areas and repairs are examined, and whether the purchaser needs films/images or only a report. Minimum wall after forming and any cold sizing should be controlled against the finished pipe, not inferred from starting strip. For long or large-diameter pipe, add straightness, ovality, end mismatch, handling supports and transport restraints so a dimensionally accepted piece arrives fit for field joining.
A page conflict is a verification prompt, not a finding that a company cannot supply the item. Preserve the observed difference, request a clean technical return and make the purchase order control final identity, geometry, responsibility and acceptance.
Send one controlled RFQ
| RFQ line | Buyer input | Supplier return |
|---|---|---|
| Identity | B862 edition, titanium grade, pipe/spool boundary and design code if applicable | Offered standard, exceptions and producing/fabricating source |
| Dimensions | OD/NPS, wall/schedule, length, tolerances, ends and fit-up datums | Signed drawing and finished dimensional report |
| Manufacturing | Starting plate/strip, forming, seam process, filler and heat treatment | Process traveller, material traceability and WPS/PQR references |
| Inspection | Visual/PT/RT/UT/ET, leak/hydro, repairs and witness points | ITP, coverage, criteria, results and record format |
| Documents/marking | MTC, weld/NDE records, heat marking, cut-length remarking and packing list | Lot-linked document index and permanent/temporary marking plan |
| Commercial | Quantity by size, packing supports, required date and destination | Current schedule, validity, exclusions and shipping boundary |
Remove any source that cannot return the exact material, deliverable, finished geometry and acceptance evidence. Compare price, schedule and terms only after technical lines, responsibility boundary and document scope are aligned.
Where Beiyu fits
Beiyu is outside the five-company set. Its welded titanium-pipe route asks for B862/edition, grade, finished OD or NPS/schedule, wall, length, ends, starting flat product, forming and welding process, condition/heat treatment, seam NDE, pressure/leak testing, dimensional report, documents, quantity, packing and destination. B861 seamless pipe and B338 tube are quoted separately.
The fields in this section describe only Beiyu’s published enquiry route. They do not score the companies above and do not transfer to another company’s catalogue.

Specification detail with sources
Beiyu Titanium publishes this list and is not part of the comparison above. For readers who want the publisher’s own figures on the same basis they would ask of any supplier on this page, the material is specified to ASTM B338, and each order carries an EN 10204 type 3.1 certificate with heat and pour numbers by order scope.
Beiyu supplies seamless pipe OD 5 to 325 mm with 0.5 to 12 mm wall in lengths to 12000 mm, and welded pipe OD 6.35 to 1219 mm with 0.5 to 25.4 mm wall in lengths to 22000 mm.
These are Beiyu published supply figures and inspection parameters, not limits taken from the standard; limit values belong to ASTM B338 and are confirmed against the exact edition named on the purchase order. Certification is stated as a production capability, and no stock position, delivery time or price is implied by any figure on this page.
