ASTM A312 TP904L Stainless Steel Seamless Pipe
Leave a message
ASTM A312 TP904L stainless steel seamless pipe is a high-quality, low-carbon, high-alloy austenitic stainless steel pipe specifically designed for exceptional corrosion resistance in highly aggressive environments.
Our TP904L seamless steel pipes are manufactured using precision cold drawing or extrusion processes in accordance with ASTM A312 standards. Through the solution annealing process (typically conducted at 1050-1150°C followed by controlled cooling), we achieve a uniform microstructure. TP904L pipes exhibit excellent formability and weldability without requiring post-weld heat treatment, with mechanical properties including a minimum tensile strength of 490 MPa and elongation ≥35%, balancing durability and workability.
GNEE's TP904L seamless pipes offer ultra-smooth inner surfaces (optional polishing treatment with surface roughness Ra ≤ 0.8μm) and strict dimensional tolerances (outer diameter ±0.10mm, wall thickness ±10%), meeting the demanding requirements of chemical processing, pollution control equipment, seawater desalination, flue gas desulfurization (FGD) systems, and high-purity chemical transportation-applications where conventional stainless steels would struggle to perform. Fully compliant with ASTM A312/ASME SA312 specifications, each pipe is accompanied by comprehensive quality documentation.

Applications
Chemical Processing Plants: Ideal for corrosive fluid transport in chemical reactions and process industries where resistance to sulfuric acid, phosphoric acid, and other aggressive chemicals is needed.
Marine Pipelines: Used in seawater desalination and marine environments where corrosion resistance to seawater and salt-induced corrosion is essential.
Oil & Gas Pipelines: Used in offshore and onshore oil & gas pipeline systems where resistance to sulfur compounds and high pressures is essential.
Power Plants: Applied in boilers, furnaces, and heat exchangers where the pipe will be exposed to high temperatures and high-pressure steam.
