ASTM A312 TP304 SS round Pipe Manufacturer
GNEE is an ISO-certified exporter of ASTM A312 steel pipes. We are a trusted distributor and reseller of ASTM A312 TP304 seamless steel pipes in your country. All our ASTM A312 TP304 stainless steel seamless pipes are tested according to international standards and specifications such as DIN, JIS, EN, and ASTM.
304 stainless steel pipe is also known as 18/8, A2, SUS304, or UNS S30400. Compared to most carbon steels, this alloy has lower thermal and electrical conductivity. GNEE supplies high-quality ASTM A312 TP304/TP304L seamless steel pipes, manufactured using cold-drawing or hot-rolling processes without welding.
ASTM A312 TP304L stainless steel round pipes have a wide range of sizes, with outer diameters from 6.0 mm to 610 mm (1/4 inch to 24 inches) and wall thicknesses from 0.5 mm to 25.4 mm (1/50 inch to 1 inch). We also offer custom sizes, including large diameter, thin-walled and thick-walled pipes, to meet the design requirements of a variety of industrial piping systems.
