Product Overview
STAINLESS STEEL 304 ERW PIPES
SS 304 ERW Pipes are manufactured from austenitic stainless steel containing chromium and nickel, providing excellent corrosion resistance, formability, and weldability.
These pipes are produced by cold-forming stainless steel strips into tubular shapes followed by high-frequency electric resistance welding (ERW), ensuring uniform weld integrity and excellent dimensional control.
At Moksh Tubes & Fittings LLP, we are a trusted manufacturer, supplier, and exporter of SS 304 ERW Pipes in India, supplying both domestic projects and Gulf / GCC markets including UAE, Saudi Arabia, Qatar, Oman, and Kuwait.
Our SS 304 / 304L ERW Pipes are widely used in chemical processing, food & dairy, pharmaceuticals, water pipelines, oil & gas, fabrication, and architectural applications.
