Stainless steel 304L pipe is a low-carbon version of 304, known for its excellent corrosion resistance, good weldability, and durability. It is commonly utilized in sectors, where cleanliness and strength are essential. Preston Pipes & Alloys is a trusted name in the stainless steel industry. They offer top-quality 304L stainless steel pipes that meet international requirements. The material contains key elements like carbon, manganese, silicon, phosphorus, sulfur, chromium and nickel. These elements provide the pipe with strength and corrosion resistance. Its mechanical qualities include a yield strength of 170 MPa, tensile strength of 485 MPa, hardness of 201 HB, and elongation of 40% making it appropriate for demanding applications.
304L stainless steel pipe resists rust in many environments including mild acids, and chemical agents. The low carbon content reduces carbide precipitation during welding. This is ideal for applications including food processing, chemical tanks, water treatment, and oil and gas systems. The pipe also works well in heat exchangers and pharmaceutical equipment. Its ability to hold up in both high and low temperatures adds to its versatility across sectors.
We supply 304L stainless steel seamless pipe in a range of specifications to meet varied needs. Available sizes include wall thickness from 0.6 to 12.7 mm and outside diameters from 1/8 inch to 12″ NPS. The schedule ranges from 5 to XXH. Pipes come in single or double lengths based on customer preference. Every ASTM A312 GR TP304L meets standards like A312 TP304L and offer consistent quality and performance.
Each A312 Gr TP304L pipe passes strict quality checks before shipment. We conduct tests for strength, surface finish, and dimensional accuracy. Visual inspection, PMI testing, hydro testing and third-party inspection reports are also available on request. Our packaging assures a safe delivery. Pipes are wrapped in waterproof materials and stored in wooden containers or bundles to prevent damage during transport. Explore the best 304L stainless steel pipe options with trusted quality and quick delivery.
