ASTM A234 WPB is the very common grade of wrought carbon steel butt weld pipe fittings which standard is ASME/ANSI B16.9.
Wrought steel pipe is hammered or forged or otherwise formed into shape at a temperature below the melting point when it has a consistency of taffy or chewing gum. For more detailed information you can refer to the standard. A link is included as the source.
Once the basic form is created the ends of WPB - (Butt Welded Pipe) are finished by machining to achieve the proper end configuration.
Zizi Engineering is one of the top manufacturer, exporter and supplier of carbon steel and alloy steel buttweld fittings which are available in various sizes, dimension and shapes according to our client’s requirement. We can supply various grades such as ASTM A234 WPB/WPC, WP9, WP91, WP5, WP11, WP12, WP22.

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.
