Analysis on the structure and application of cross casing head by manufacturer

The casing head body is the main part of casing head device, and the casing head cross is an indispensable and important part in api6a field. It not only has the ability to resist the corrosion of hydrogen sulfide and carbon dioxide, but also has the ability to bear the connection and sealing with the carrier, as well as the ability to withstand high pressure (liquid pressure or gas pressure) sealing. The selection of cross casing head material also meets the requirements of API 6a and NACE mr0175. If it doesn't work, there will be catastrophic losses. Therefore, the safe use of casing head short pipe is very important.
