Common type of Butt weld pipe fittings

Butt weld fittings are available as elbows, tees, caps, reduces and out lets (olets).

Long radius elbows
Long radius (LR) elbows

Long Radius (LR) Elbows – radius is 1.5 times the pipe diameter

Short radius elbows
Short radius (SR) elbows

Short Radius (SR) Elbows – radius is 1.0 times the pipe diameter

API Pipe bend

Pipe bend can be made of variety materials,like carbon steel,alloy steel,stainless steel,low temperature steel or high performance steel,etc.

Tees straight and reducing

We can provide seamless tube tees and welding tube tees,which can also be divided into straight tees and reducing tees.

Carbon steel end caps

Pipe cap is usually used for protecting the end of pipe and other fittings,so the shape is disigned according to the shape of pipe line.
