Schedule 40s ASTM A312 Tube WP-S 304L
Pierced directly from a solid metal billet—not welded—this wrought seamless construction eliminates potential weak points, giving you a pipe that holds firm against mechanical stress, high temperatures, and the relentless demands of aggressive fluid transfer. At its core, this pipe is built from low-carbon austenitic stainless steel (304L), a grade specifically engineered to resist harmful carbide precipitation during welding. This means welds stay strong and a system maintains full intergranular corrosion resistance, even after repeated heat exposure. Combined with Schedule 40 wall thickness, it offers the structural integrity needed to handle moderate to high pressure applications with confidence. Compliance with ASTM A312 the governing standard for austenitic stainless steel pipes in corrosive service and elevated temperature environments, ensures every unit meets the rigorous quality benchmarks your operations depend on. Its versatility makes it a trusted choice across demanding industries. In chemical plants, it reliably conveys acids, alkalis, and mild chemicals without degradation. In food, dairy, and beverage processing, its high purity characteristics and resistance to frequent sterilisation cycles keep pipelines clean and compliant. It also performs dependably when transporting compressed air, natural gas, and steam, where consistent performance isn't optional.
Summary:
- Highly durable, corrosion resistant pipe used for high temperature and aggressive industrial fluid transfers
- WP-S indicates the component is a wrought seamless pipe or tube, meaning it is pierced from a solid metal millet rather than welded
- A low carbon austenitic stainless steel, prevents harmful carbide precipitation during welding and ensures strong intergranular corrosion resistance
- ASTM A312 is the standard that governs seamless and welded austenitic stainless steel pipes intended for corrosive service and elevated temperatures
- Schedule 40 indicates it denotes a specific wall thickness that offers great structural integrity and moderate to high pressure handling capabilities
-
Applications:
Common used in;
- The transporting of mild chemicals, acids and alkalis in chemical plants
- Pipelines conveying consumable fluids in the food, dairy and beverage industries
- Systems requiring high purity and the ability to withstand frequent sterilisation without corroding
- Safely transferring compressed air, natural gas and steam
