Finished Casing Head
Products can be modulated, heat treated and finished according to customer requirements, with good durability.
We can make 45#, 40Cr, 30CrMo, 35CrMo, 42CrMo, 18CrNiMo7-6 and other materials according to customer requirements. According to different weights, we can forge on different forging equipment units. The weight of forged products can reach 6kg-500kg. It needs to be completed by heating, pre-forging, forming, trimming and other processes.
The casing head is usually made of 35 or 42 Cr Mo alloy structural steel. There is also a casing hanger in the casing head, which is used to hang the casing string of corresponding specifications and seal the annulus. BOP stack shall be installed on it. After the well is completed, the Christmas tree is installed on the casing head.
The production of casing head generally includes the following process flow:
1. Blank casting: casting materials into workpieces.
2. Rough machining, that is, preliminary cutting of workpiece blanks.
3. Finish turning: use the lathe to process the rough cutting workpiece to the design accuracy.
4. Bore the diameter, and use the boring machine to bore out the designed inner diameter.
5. When drilling, the external connecting bolts of the drill are drilled out.
6. Heat treatment: quenching and tempering the workpiece.
7. Inspection and test: the geometric dimension, hardness, roughness, internal and external defects of the casing head that has been processed shall be inspected and NDT shall be carried out.
Welcome new and old customers to consult and communicate.
