Tubing for instrumentation, heat exchange and fabrication. 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 and welded tubes: 1/2–12 in; wall 0.4–12.7 mm in the catalogue. Stainless grades include 304/304L, 316/316L, 904L and duplex 2205; specify tube duty and the applicable material/dimensional standard.
The catalogue also describes carbon, alloy, nickel, copper-nickel and titanium tube 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 |
|---|---|
| Tube service / standard | Heat-exchanger, instrumentation or mechanical tubing uses different standards; identify the duty and material grade. |
| Grade range | 304/304L · 316/316L · Duplex 2205 and other grades on request; confirm availability |
| Tube dimensions | Outside diameter × wall thickness × length, dimensional tolerances and bend needs. |
| Tube condition | Seamless or welded route, surface finish and inspection or test requirements to the chosen tube 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, tube dimensions, quantity, inspection requirements and destination. We will confirm what can be sourced for the exact enquiry.
Tube condition: Seamless or welded route, surface finish and inspection or test requirements to the chosen tube 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 |
