What does ASTM A234 WP9 fittings mean?
Preferred for applications in demanding applications, these fittings are produced from either carbon steel or alloy steel grades. They have moderately high tensile strength and little to no corrosion resistance properties.
What is the extrusion method for manufacturing SA 234 gr WP9 CL1 elbow?
The cold extrusion method is intended for the manufacture of small or medium size SA 234 Gr WP9 Cl1 Elbows. Here, a cut pipe piece with the same diameter as a finished product will be pushed through a cold bending die. This process transforms the pipe into its desired shape i.e. the elbow. To avoid friction, lubrication is applied to the pipe. The lubricant also protects the surface of the ASTM A234 WP9 Fittings. The elbow is then sent for heat treatment and machining.
The heat treatment process for alloy steel WP9 tee
The fittings are formed at a specific higher temperature. After the fittings are formed, they are permitted to cool down rapidly at a temperature below the alloy’s critical range. The rate of cooling should be similar to the rate of air cooling.
How do you install ASTM A234 WP9 end cap?
End caps have a diameter that is larger than a pipe. They are available in both threaded and non-threaded options. Usually, a threaded ASTM A234 WP9 End Cap is preferred because it is easy to install. They just have to be attached to the threads of the pipe without a need for specific equipment. Non-threaded caps are fitted by welding. Although they tend to be free from leaks, care needs to be taken before, during and after welding to prevent intergranular corrosion.
Advantages of ASTM A234 WP9 pipe fittings
Alloy steel fittings have better corrosion resistance, unlike carbon steel grades. The corrosion resistance can be increased by using a coating on the fittings. In addition to this, the ASTM A234 WP9 Pipe Fittings gain better mechanical properties, because it has been alloyed with different elements.
