ASTM A269 TP304L Stainless Steel Seamless Pipe For Chemical Processing
Leave a message
ASTM A269 TP304L is the low-carbon variant of Grade 304 stainless steel and is widely used for general corrosion-resistant applications due to its higher chromium and nickel content. All our ASTM A269 SS 304L seamless stainless steel tubes are supplied in a fully heat-treated condition to ensure stable mechanical properties and improved corrosion resistance.
GNEE supplies ASTM A269 304L stainless steel tubing in both welded and seamless forms, with customized dimensions and standard specifications available. Our pricing in India is highly competitive, making us a preferred supplier for large-scale projects. Large-diameter ASTM A269 TP304L seamless pipes are extensively used in oil and gas exploration, refining and petrochemical industries, fertilizer plants, LNG terminals, long-distance natural gas and water pipelines, and general engineering applications.
In addition, we supply ASME SA 269 304L stainless steel coiled tubing, available in outer diameters ranging from 1/8 inch to 5 inches and wall thicknesses from 0.015 inch to 0.320 inch, suitable for instrumentation, heat exchangers, and precision fluid transport systems.

Applications
ASTM A269 TP304L seamless pipes are widely used in industries requiring high strength and corrosion resistance. Common applications include:
Chemical Processing: Transport of corrosive chemicals like acids and alkalis.
Food and Beverage: Piping for food-grade liquids and sanitation systems.
Pharmaceuticals: Hygienic tubing for drug manufacturing and sterile environments.
Oil and Gas: Pipes for upstream, midstream, and downstream operations.
Power Plants: Heat exchangers and boiler tubes.
Marine Industry: Tubing exposed to saltwater and harsh marine environments.
All ASTM A269 TP304L stainless steel pipes we supply have undergone multiple mechanical property tests, including flaring tests, flange tests, hardness tests, and reverse flattening tests. In addition, each ASTM A269 TP304L seamless stainless steel pipe shall also undergo non-destructive electrical testing or hydrostatic testing.
