Alloy 825 tube pages can combine seamless tube, seamless pipe and welded pipe on one screen. Four company-owned sources passed this review. Their useful difference is the product route they expose; a buyer still has to bind UNS N08825, construction, dimensions and one applicable specification on the RFQ.
How the four Alloy 825 pages were selected
We froze the query Alloy 825 tube supplier manufacturer N08825 on 1 September 2026. Eligible results were accessible company-owned pages with a direct Alloy 825 tube or pipe route. Beiyu, directories, marketplaces, third-party lists and duplicate domains were excluded. Runhai’s candidate page timed out during source review, so Langley Alloys entered as the next eligible first-party material page. Search-snapshot order is not a supplier score.
| Company page | Product route | Standard wording | Published dimensions | RFQ check |
|---|---|---|---|---|
| RIC Tubes | N08825 seamless tube, seamless pipe and welded pipe | B163/SB163 for the tube table; B423/SB423 seamless pipe; B705/SB705 welded pipe | Tube 6-114.3 mm OD, 0.5-15 mm wall, length to 20 m; pipe uses separate NPS ranges | Use the form-specific table; do not merge it with the broader headline range |
| XTD Stainless | Alloy 825 seamless tube | ASTM B163 in an N08825 product context | A consolidated numeric envelope is not stated on the reviewed page | Return OD, wall, length, tolerance, condition and certificate with the offered B163 route |
| PAC Stainless | Cold-finished, bright-annealed Alloy 825 tubing | ASTM B163/B829, ASME SB163 and NACE MR0175 are named | 0.250-0.750 in OD and 0.035-0.065 in wall | Confirm which standard/edition, length, tolerance and NACE/project requirements apply to the quoted item |
| Langley Alloys | On 1 September 2026, the material page stated tube was stocked and plate/fittings were by enquiry | The main page’s ASTM B425 statement concerns bar, not tube; a separate tube data sheet is offered | A numeric tube range is not stated on the reviewed page | Request the tube data sheet, confirm current availability and bind its product specification, size and condition to the quotation |
A material page can mention several product forms and standards without mapping every standard to every form. The RFQ should not copy the nearest ASTM number. It should name tube or pipe, seamless or welded construction and the applicable product specification as one controlled line.
Choose tube, seamless pipe or welded pipe first
| Route | Typical ordering dimensions | Control point |
|---|---|---|
| Seamless tube | OD and wall or OD and ID, with tube tolerances and length | Do not replace the tube specification with a pipe standard shown elsewhere on the page |
| Seamless pipe | NPS, schedule or explicit OD/wall, length and ends | Confirm whether the offer follows a pipe product specification and dimensional convention |
| Welded pipe or tube | NPS or OD/wall, weld route, heat treatment, length and ends | State weld inspection, solution treatment and NDE requirements |
| Capillary or precision tube | OD, ID/wall, tight tolerances, straightness, cleanliness and cut length | Ask for a form-specific envelope instead of assuming the standard tube range applies |
NACE MR0175 or another application document does not replace the product specification. It adds service-related requirements. The buyer and project engineer must state the required edition, environmental limits and acceptance evidence.
Send one controlled Alloy 825 tube RFQ
| RFQ line | Buyer input | Supplier return |
|---|---|---|
| Material | Alloy 825 / UNS N08825 and any project chemistry controls | Exact offered designation and heat/lot chemistry |
| Product route | Tube or pipe; seamless, welded or capillary | One construction tied to the quoted dimensions |
| Dimensions | OD/NPS, wall or schedule, tolerances, straightness, length and ends | Finished dimensions and allowed variation in one unit system |
| Specification and condition | Product specification/edition, solution treatment, surface and cleanliness | Governing standard and named delivery condition |
| Inspection | Chemistry, mechanical/dimensional tests, hydrostatic/eddy-current or other NDE, and sampling | Acceptance plan and test records |
| Service and records | Medium, temperature, pressure, corrosion/NACE requirements, traceability and certificate type | Document schedule and stated exceptions |
Where Beiyu fits
Beiyu is outside the four-company set. Its current Alloy 825 product source identifies UNS N08825 and multiple tube-family form envelopes. ASTM B163, B407, B423, B514, B515, B673, B674, B704 and B705 plus ASME adoptions appear as a row-level standard set; Beiyu does not assign the whole set to one construction. The quote confirms form, construction, dimensions, condition, applicable product specification, inspection and certificate scope.
How to use this comparison
Begin with the product route, then screen the company pages for a matching size and condition. Require every supplier to return the same UNS, form, standard, dimensions, heat treatment and inspection fields. Compare commercial terms only after those technical lines agree.

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.
