Seamless Carbon Steel Tube Fittings ASME B16.9 1/2" - 80" High Performance

Carbon Steel Pipe Fittings ASTM 234 Butt Weld Fittings ASME B16.9

ASTM A234 butt weld pipe fittings are available in wrought carbon steel and alloy steel material of seamless and welded construction covered by the latest revision of ASME B16.9, B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, and MSS-SP-97. These fittings are for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.

Type of ASTM A234 WPB Pipe Fittings

Elbow

According to the angle, they can be divded into 30 degree elbow, 45 degree elbow and 90 degree elbow.

For the bending radius, there are long radius (1.5D) and short radius (1D)

Tee

When the run pipe size is same as branch pipe size, we can call it as equal tee or straight tee.

While the branch diameter is small than run pipe diameter, it is reducing tee.

Cap

It is used to seal the end of pipeline by welding. And they have same size and thickness.

Bend

It has same function and degree as elbow which used to change the direction of pipeline. The difference is the bending radius. Usually bend radius is 3D or above. Such 3D, 4D, 5D, 6D,7D, 8D, 9D, 10D, etc.

Stub End

Stub end is used to match with the lap joint flange. There are two type that long pattern and short pattern.
