Stainless Steel Pipes & Tubes Manufacturer, Supplier and Exporter in India
Jade Alloys is a trusted manufacturer, supplier and exporter of stainless steel pipes and tubes, produced from prime-grade raw material using precision manufacturing and cutting-edge finishing. Our stainless steel pipe and stainless steel tubing range is engineered by enriching the steel matrix with chromium and nickel to deliver exceptional corrosion resistance, strength and durability across the most demanding environments. As established stainless steel tubing suppliers, we hold a large ready inventory of SS pipe and SS tube in multiple diameters, wall thicknesses and lengths, so orders ship quickly and project downtime stays low.
Every batch is fully tested for chemical composition and mechanical properties before dispatch, and each order is backed by complete material test certificates and export documentation. Alongside our pipe range we also supply matching stainless steel round bars, stainless steel sheets & plates and stainless steel fasteners for complete piping and structural packages.
What Is a Stainless Steel Pipe & Tube?
A stainless steel pipe is a hollow, longitudinal section usually round used to convey fluids, gases and slurries, while stainless steel tubing is dimensioned to tighter tolerances for structural, mechanical, instrumentation and heat-exchanger use. Because stainless steel forms a passive chromium-rich oxide film stabilised by nickel, it resists oxidation, pitting and crevice corrosion when exposed to chemicals, seawater and elevated temperatures. Products divide broadly into seamless pipe (pierced and drawn from a solid billet) and welded pipe (formed and longitudinally welded as ERW, EFW or LSAW). To understand how alloying elements shape this performance, see our guide to stainless steel composition and key element percentages.

Types of Stainless Steel Pipes & Tubes
Seamless Pipes & Tubes
Hot-rolled or cold-drawn, no weld seam — ideal for high-pressure and high-temperature service (ASTM A312 / A213).
Welded Pipes & Tubes
Longitudinally welded to A312 / A249 for general and structural applications at economical cost.
ERW Pipes & Tubes
Electric Resistance Welded pipe for high-pressure and utility lines.
EFW / Fabricated Pipes
Electric Fusion Welded and LSAW pipe for large-diameter, heavy-wall requirements (ASTM A358).
Square & Rectangular
Hollow sections for structural, architectural and mechanical use.
Hydraulic, Coiled & U-Tubes
Instrumentation, heat-exchanger and sanitary tubing in coiled, U-shape and pan-cake forms.
