Completed Casing Head
The product can be punched many times, and the forging ratio is enhanced, and the durability is good.
This product can be repeatedly forged after heating, and can also be modulated and heat treated and finished according to customer requirements. After repeated forging, the forging ratio is high and the durability is good. It is suitable for key parts of equipment. For casing heads, our company can forge 10kg-5000kg forgings, and can forge a variety of materials including 42CrMo, 4140, 4130, 40Cr, 20CrMnMo, 18CrNiMo7-6, 410SS. Our company has API certificate and SQ1 certificate and has many years of experience in petroleum product processing.
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 finished casing head shall be inspected and NDT shall be carried out.
Customers in any industry using forgings can request a quote for any number of forged products, from one prototype at a time and small batches to high volume production. Welcome new and old customers to come to communicate.
