Product Overview

Threaded Pipe Fittings

Threaded joints probably represent the oldest method of joining piping systems. Threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller. Threaded piping is commonly used in low-cost, noncritical applications such as domestic water, fire protection and industrial cooling water systems.

FAQ

Frequently Asked Questions

Threaded fittings are pipe fittings joined by screwing male and female threaded ends together. They are mainly used for small bore piping (NPS 2 or smaller) in low-cost, noncritical applications like domestic water, fire protection and cooling water systems.

Our threaded fittings are manufactured as per ASME B16.11 covering forged fittings in socket-weld and threaded types.

We supply threaded fittings in NPT (National Pipe Taper), BSP (British Standard Pipe) and BSPT (British Standard Pipe Taper) thread forms as per customer requirement.
