	Oil and gas equipment forgings

The company's oil and gas equipment is divided into wellhead devices and forgings for Christmas tree equipment and deep sea oil and gas equipment forgings. The wellhead device and the Christmas tree equipment are important equipment for oil and gas exploitation. They are composed of casing head, tubing head, and oil production (gas) tree. They are used to connect the casing string and the tubing string, and seal the casing between each layer and with The annular space between the tubing can control the pressure of the production wellhead and regulate the flow of the oil (gas) wellhead, and can also be used for special operations such as acid fracturing, water injection, and testing. The structure of deep-sea oil and gas equipment is similar to that of onshore and shallow sea oil and gas equipment, including Christmas tree, manifold, valve body and other components. However, deep-sea oil and gas equipment has higher requirements on various performance indexes of its forgings such as pressure bearing and corrosion resistance. , The company can produce various pressure levels of deep sea oil and gas equipment tubing head, casing head and various valve body and other components
