Tantalum tube enquiries are usually small, drawing-sensitive and expensive enough that an omitted construction or tolerance changes the buying decision. This comparison records four company-owned pages without turning supplier claims into qualification evidence.
How the four tantalum tube pages were selected
We froze the query top tantalum tube suppliers tantalum pipe manufacturer on 1 September 2026. We included accessible company-owned product pages directly about tantalum tube or pipe. Beiyu, directories, marketplaces, market reports and repeat URLs from the same domain were excluded. We included the first four eligible company-owned pages under the stated page-specific count. Their order records visibility, not performance.
| Company page | Page route | Material and standard wording | Published dimensions | RFQ check |
|---|---|---|---|---|
| Eagle Alloys | Stock and custom tantalum tubing and pipe | Commercially pure, medical-grade, Ta-2.5W, Ta-7.5W, Ta-10W and Ta-40Nb; ASTM B521 and ISO 13782 are among the page statements | 0.039-6.5 in OD, 0.008-0.630 in wall, up to 20 ft length; a stock list gives individual combinations | Which alloy, construction and one product standard apply to the selected stock or custom size? |
| Stanford Advanced Materials | Seamless and welded tantalum tube/pipe; customized dimensions | R05200 and R05400, ASTM B521, purity ≥99.9% or customized | No numeric general envelope stated on the reviewed page | Return construction, OD, wall, length, tolerance and condition instead of “customized” alone |
| Baoji Hanz | Category page linking seamless, pure and other tantalum tube entries; customization and stock are stated | Grade, UNS and governing standard are not stated on the reviewed category page | No consolidated numeric envelope stated | Which linked product page or drawing establishes alloy, construction, standard and dimensions? |
| XAC MH | Tube/pipe produced by extrusion, rolling and annealing; custom route | Ta1 (R05200), Ta2 (R05400), purity ≥99.95%, ASTM B521; annealed | 3-200 mm OD, 0.3-15 mm wall and up to 6,000 mm length | Confirm whether the quoted construction and drawing fall inside the stated range and which inspection records are included |
Inventory wording and “customized” are status words, not dimensions. Ask the supplier to identify the exact available line or production route, then bind it to the same grade, construction, tolerances and document scope used by every bidder.
Seamless, welded and capillary are different enquiries
| Route | Order fields that matter | Evidence to request |
|---|---|---|
| Seamless tube | Alloy/UNS, OD, wall, length, reductions, annealed condition, straightness and surface | Confirmed manufacturing route, dimensional report and lot-linked MTC |
| Welded tube or pipe | Starting strip/plate identity, forming and welding route, weld acceptance, heat treatment and dimensions | Weld procedure/inspection scope required by the project and traceability to starting material |
| Capillary or very thin wall | OD/ID/wall tolerances, concentricity, cut length, end finish, cleanliness and handling | Measurement method, sample or first-article record where required |
ASTM B521 can provide the product-specification route when the ordered tantalum tube falls within its scope, but it does not choose seamless versus welded or write the drawing. The purchaser still controls alloy, construction, dimensions, condition and inspection.
Send one controlled tantalum tube RFQ
| RFQ field | What to state | What should come back |
|---|---|---|
| Alloy identity | R05200, R05400, Ta-2.5W or another exact grade/UNS, with governing standard and revision | The same material identity on quotation, acknowledgement and MTC |
| Construction | Seamless, welded, welded-and-drawn or drawing-specified route | The actual offered construction and starting-material traceability |
| Dimensions | OD, wall/ID, tolerances, straightness, length, ends and drawing revision | Finished dimensions in the order unit |
| Condition and surface | Annealed/worked condition, pickled/polished/machined surface and cleanliness | Named delivery state and any measurement basis |
| Service | Process chemistry, concentration, temperature, pressure/vacuum and fabrication after receipt | Any application limits clearly separated from material certification |
| Inspection and packing | Chemistry, mechanical/dimensional testing, weld/NDE scope, MTC, marking and protected export packing | Lot-linked records and a packing plan appropriate to thin walls and finished ends |
Where Beiyu fits
Beiyu is outside the four-company set. Its live tantalum pipe-and-tube page covers unalloyed R05200/R05400 and Ta-2.5W routes, seamless or welded construction under ASTM B521 when specified, annealed condition and an EN 10204 3.1 mill test certificate on request. The quotation confirms the alloy, OD, wall, length, construction, condition, surface, quantity and document scope.
How to use this comparison
Choose construction before comparing size ranges. Then send the same drawing and order fields to the eligible companies. A stock line can be fast but wrong for the alloy or wall; a custom claim can be broad but unpriced. Compare only complete replies that preserve the same technical basis.

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 tube OD 5 to 325 mm with 0.5 to 12 mm wall in lengths to 12000 mm, welded tube OD 6.35 to 1219 mm with 0.5 to 25.4 mm wall in lengths to 22000 mm, and capillary OD 1 to 5 mm with 0.1 to 2 mm wall.
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.
