It has a bottom height, lower on the rig floor provides maximum operating space. It according to the API .6A specification the design and manufacture, the shell material in the working pressure of less than or equal to 3000Psi selection of low alloy cast steel, working pressure greater than 5000Psi when the use of forged low alloy steel, in accordance with the requirements of users in the pad ring groove welding stainless steel, improving the sealing parts of the corrosion resistance and sealing performance.

The material of the main body of quenching and tempering heat treatment, after the molding process to conduct a comprehensive ultrasonic examination, and ensure the safety of products. Matched with the casing hanger to hang the largest casing weight and can not be damaged, it does not need to process would be to

. it can rely on the gravity base sealing, can also be used to seal the annular space top wire pressing.

Casing head and the bottom of the casing connection can be connected by a screw thread or welding, welding after the pressure test hole inspection weld sealing quality.
