Product Overview
STAINLESS STEEL 304 WELDED PIPES
SS 304 Welded Pipes are manufactured from austenitic stainless steel containing chromium and nickel, providing excellent corrosion resistance, formability, and weldability. These pipes are produced by forming stainless steel coils or plates into tubular shapes and welding the seam using advanced welding techniques such as ERW, EFW, or TIG welding, followed by heat treatment and finishing.
At Moksh Tubes & Fittings LLP, we are a leading manufacturer, supplier, and exporter of SS 304 Welded Pipes in India, supplying high-quality pipes to domestic infrastructure projects and international markets including UAE, Saudi Arabia, Qatar, Oman, and Kuwait.
SS 304 Welded Pipes are widely used in food processing, dairy, pharmaceuticals, water pipelines, oil & gas utilities, fabrication, and architectural applications where hygiene, corrosion resistance, and cost efficiency are essential.
