Stainless Steel Pipe Fittings

A piping system is only as strong as its connections. Ashwin Steel supplies a comprehensive portfolio of stainless steel pipe fittings designed to ensure leak-proof, high-integrity joints in critical fluid handling systems. Our fittings are precision-engineered to match the exact specifications of the connecting pipes, guaranteeing smooth flow and structural stability.

Whether you require large diameter butt-weld fittings for a petrochemical pipeline or high-pressure forged fittings for hydraulic applications, we have you covered. Our products undergo rigorous quality checks, including dimensional inspection and hydrostatic testing, to ensure they exceed industry safety standards.

Frequently Asked Questions

Frequently Asked Questions

Buttweld fittings are welded directly to the pipe ends and are generally used for larger diameters (1/2" and up). Forged fittings (socket weld or threaded) are machined from solid forgings, used primarily for smaller diameter pipes, and can withstand much higher pressures.
Concentric reducers are used when the centerlines of the two pipes align, typically in vertical runs. Eccentric reducers keep one side flat (usually the bottom) and are used in horizontal runs to prevent pooling of liquids or trapping of gases.
Yes, we supply a wide range of branch connections including Weldolets, Sockolets, and Threadolets for reliable, high-strength branch connections on main pipes.
