Alloy Steel Pipe Fittings ASTM 234 WP5 / WP9 / WP11 / WP12 / WP22
Alloy steel butt weld pipe fittings have many grades which are ASTM A234 WP5 CL1 / CL3, WP9 CL1 / CL3, WP11 CL1 / CL2 / CL3. WP12 CL1 / CL2, WP22 CL1 / CL2
Alloy Steel ASTM A234 Buttweld Fittings are used to connections between multiple pipes in different sizes. We have Alloy Steel ASTM A234 Fittings which include all types of conventional as well as customised fittings compliant with ASTM A234, specification covering Alloy Steel fittings of seamless and welded construction, stated to use in the pressure vessel fabrication and pressure piping systems for operations at moderate to elevated temperatures.
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.
Specification of Wrought Alloy Steel Pipe Fittings
| Standard | ASTM A234, ASME B16.9 |
| Size | 1/8” NB TO 48” NB. (Seamless & 100% X-Ray Welded, Fabricated) |
| Thickness | Schedule S10, S20, S30, STD, S40, S60, XS, S80, S100, S120, S140, S160, XXS |
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.
