Petrochemical facilities often handle hydrocarbons, process chemicals, corrosive fluids and elevated-temperature services. Material selection therefore needs to consider corrosion resistance, pressure, temperature, fluid composition and applicable piping codes.
316L stainless steel seamless pipe is frequently selected when improved corrosion resistance over 304 stainless steel is required.
Typical advantages include:
- Better chloride pitting resistance than 304 stainless steel
- Good resistance to many chemical environments
- Excellent weldability
- Good ductility and toughness
- Suitable for demanding industrial piping
- Low-carbon grade for welded fabrication
- Seamless construction for process piping applications
ASTM A312 TP316L Schedule 10S Stainless Steel Seamless Pipe can be used in a range of petrochemical and process-industrial applications, subject to engineering design and service conditions.

A: ASTM A312 TP316L is a low-carbon austenitic stainless steel pipe grade specified for seamless and welded pipe used in corrosive and high-temperature service. TP316L corresponds to UNS S31603.
A: Schedule 10S is a stainless steel pipe wall designation generally associated with ASME B36.19M. The actual wall thickness depends on the nominal pipe size.
A: Yes. When specified as a seamless pipe, it is manufactured without a longitudinal weld seam. ASTM A312 also covers welded stainless steel pipe, so the manufacturing type should be clearly stated on the purchase order.
A: In many corrosive environments, 316L provides better resistance to pitting and crevice corrosion because it contains molybdenum. However, the appropriate grade should always be selected based on the actual process medium, temperature, chloride concentration and design conditions.
A: Yes. TP316L has good weldability and is commonly welded using TIG, MIG and other suitable stainless steel welding processes. Welding procedures should follow the applicable project specifications and welding codes.
A: Yes. EN 10204 3.1 Mill Test Certificates can be provided when required, including chemical composition and mechanical test results for the supplied material.
A: We can supply a range of nominal pipe sizes according to ASME B36.19M Schedule 10S, with OD, wall thickness and length options depending on availability and project requirements.
A: Schedule 10S is a stainless steel pipe designation used with ASME B36.19M, while Schedule 10 is generally associated with carbon and alloy steel dimensions under ASME B36.10M. For stainless steel piping, the applicable dimensional standard should be confirmed.
