Illustrative product image. Confirm exact finish and form against the quoted material.
Process and structural piping in multiple grades. Metalex can discuss grade, form, finish, dimensional tolerances, documentation and packing with your procurement team. Confirm stock and delivery against your purchase specification.
Material grades are confirmed for the precise product and service. State the required standard and grade when enquiring.
Seamless pipes: 1/2–24 in; welded pipes: 1/2–60 in; schedules 5–XXS. Catalogue examples: 304, 304L, 316, 316L, 904L, duplex UNS S31803/S32205 and super duplex UNS S32750/S32760. The catalogue names ASME B36.10 for dimensions; confirm the applicable stainless dimensional and material standards for the actual pipe.
The catalogue also lists carbon-steel, alloy-steel, nickel-alloy, copper-nickel and titanium pipe families.
Metalex catalogue (2022) describes a product range, not real-time stock or a test certificate. Confirm grade, dimensions and documentation for your enquiry.
| Detail | Options to specify |
|---|---|
| Pipe material standard | ASTM A312 is a common reference for austenitic stainless process pipe; confirm grade, route and service standard for the order. |
| Grade range | 304/304L · 316/316L · Duplex 2205 and other grades on request; confirm availability |
| Nominal size / wall | NPS and schedule or outside diameter × wall thickness, plus length and end preparation. |
| Manufacturing route | Seamless or welded pipe as specified; inspection and pressure testing depend on the applicable standard. |
| Documentation | Ask which certificate and heat or batch traceability documents are available for the specific material offered. |
Send the product type, applicable standard, grade or material, nominal size / wall, quantity, inspection requirements and destination. We will confirm what can be sourced for the exact enquiry.
Manufacturing route: Seamless or welded pipe as specified; inspection and pressure testing depend on the applicable standard. Material and dimensional standards, tests and certificate type should be agreed for this product before ordering.
| Grade | Typical selection reason | Check before ordering |
|---|---|---|
| 304 / 304L | General fabrication and mild process environments | Welded assemblies: verify L-grade certification |
| 316 / 316L | Added molybdenum for improved pitting resistance in many chloride environments | Assess chloride concentration, temperature and crevices |
| Duplex 2205 | Higher yield strength and better chloride SCC resistance than common austenitic grades | Confirm UNS S32205 or S31803 and welding procedure |
