Casing Head
The product may be punched normally, and the forging ratio is stronger, and the sturdiness is right.
This product may be time and again solid after heating, and also can be modulated and heat handled and finished according to purchaser necessities. after repeated forging, the forging ratio is excessive and the durability is good. it's miles suitable for key elements of gadget. for casing heads, our employer can forge 10kg-5000kg forgings, and can forge an expansion of materials along with 42CrMo, 4140, 4130, 40Cr, 20CrMnMo, 18CrNiMo7-6, 410ss. our employer has API certificate and SQ1 certificate and has many years of revel in 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 casing strings 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 processed casing head shall be inspected and NDT shall be carried out.
Customers in any enterprise the usage of forgings can request a quote for any range of solid merchandise, from one prototype at a time and small batches to high volume manufacturing. welcome new and old customers to return to talk.
