Nickel 200 and Nickel 201 tube quotations are comparable only when grade, seamless or welded construction, finished dimensions and the applicable product specification are stated together. Five supplier pages met the source gate, but their public fields vary enough that a buyer still needs one controlled RFQ.
How the five Nickel 200/201 pages were selected
We froze the query Nickel 200 Nickel 201 tube supplier manufacturer on 1 September 2026. Eligible results were accessible company-owned product pages directly about Nickel 200 or 201 tube/pipe. Beiyu, directories, marketplaces, third-party lists and duplicate domains were excluded. The order below records the resulting snapshot and carries no supplier score.
| Company page | Construction or page role | Material and standard wording | Published dimensions | RFQ check |
|---|---|---|---|---|
| Fairy Metal | Seamless and welded tube routes | N02200/N02201; ASTM B163/SB163 named | Seamless 3.35-101.6 mm OD; welded 6-152 mm OD | Ask which standard, wall/length envelope and tolerance apply to each construction |
| Reliab Metal | Combined Nickel 200/201 seamless product page | ASTM B163 and B165 are displayed together | 1.5-150 mm OD, 0.3-10 mm wall; MOQ 1 kg stated | Confirm whether tube or pipe is quoted and which product specification actually governs it |
| Harald Pihl | Single inventory-line tube/pipe route, article 10516 | N02200/N02201 and ASTM B161 | One field says 88.90 × 3.10 mm while page prose says 88.9 × 3.05 mm | Resolve the wall discrepancy and confirm grade, current availability and certificate before ordering |
| U.S. Metals | Nickel seamless and welded heater-tube supplier page | N02200/N02201; B/SB161 and B/SB163 for seamless, B730 for welded | No numeric envelope stated on the reviewed page | Confirm grade, construction, applicable edition, OD, wall, length and availability on the quotation |
| Dongmeng Metal | Custom seamless pipe and tube page | N02200/N02201 and ASTM B161 | No numeric envelope stated in the reviewed fields | Confirm tube versus pipe, finished dimensions, condition, tolerance and inspection scope |
ASTM B163, B161 and B165 are not interchangeable labels. A page may place tube and pipe standards together for navigation or marketing. The purchase order must name the product form and one governing acceptance route that applies to it.
Separate grade, construction, product specification and service basis
| Decision | Examples from the reviewed pages | Required confirmation |
|---|---|---|
| Grade | Nickel 200 / N02200 or Nickel 201 / N02201 | Exact UNS and chemistry on the quotation and material certificate |
| Construction | Seamless, welded, capillary, tube or pipe wording | One construction tied to the dimensions and tolerances |
| Product specification | B163, B161 or B165 appears on different supplier pages | The specification applicable to the ordered product form, edition and any supplementary requirements |
| Service basis | General corrosion and elevated-temperature wording | Design temperature, fluid, concentration, pressure, fabrication and engineering acceptance |
Nickel 201 is the lower-carbon grade used for extended elevated-temperature service. That material distinction does not select the tube construction or validate a design temperature by itself. The project engineer still has to set the service and design-code requirements.
Send one controlled Nickel 200/201 tube RFQ
| RFQ line | Buyer input | Supplier return |
|---|---|---|
| Material | Nickel 200/N02200 or Nickel 201/N02201 | Exact offered designation and chemistry certificate |
| Form and construction | Tube or pipe; seamless, welded or capillary | Construction and manufacturing route tied to the item |
| Dimensions | OD, wall or ID, tolerances, straightness, length and ends | Finished values and allowed variation in one unit system |
| Specification and condition | Applicable product specification, edition, heat treatment and surface | Governing standard and stated delivery condition |
| Service controls | Temperature, medium, concentration, pressure and downstream fabrication | Exceptions or limits stated before order |
| Inspection and records | Chemistry, mechanical/dimensional tests, NDE, sampling, traceability and certificate | Document schedule linked to the supplied heat/lot |
Where Beiyu fits
Beiyu is not in the five-company set. Its current Nickel 200/201 source lists N02200 and N02201; seamless tube at 5-325 mm OD, 0.5-12 mm wall and lengths to 12,000 mm; welded tube at 6.35-1,219 mm OD, 0.5-25 mm wall and lengths to 12,000 mm; and capillary tube at 1-5 mm OD, 0.1-2 mm wall and lengths to 6,000 mm. These are enquiry envelopes, not stock. In that source, ASTM B163 is paired only with seamless tube. Beiyu confirms grade, construction, dimensions, condition and document scope at quotation.
How to use this comparison
Choose the grade and construction before screening a published size range. Send one identical RFQ line to the pages that remain. Resolve every tube/pipe or standard mismatch in writing, then compare the technical offers, inspection scope and commercial terms.

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.
