Casing And Tubing factory

API 5CT J55 casing is a seamless steel pipe applied in supporting the wall of petroleum and gas wells in order to ensure that the well is operating normally during and after the drilling process. Each oil well will need several layers of casings depending on the different drilling depth and geological conditions. 5CT seamless casing has an excellent elongation property. After the casing is installed in the well, the well is be cemented. So seamless steel casing is not reusable. Therefore, casing pipe consumption will occupy more than 70% of the whole oil well pipes.
Properties: API 5CT casing tube is cooled after tempering process. This method can help the seamless casing avoid the high temperature brittleness and gain toughness, quenching method is adopted to reduce harmful elements and impurities effectively.
Applications: J55 casing pipe is widely used in the foundation works of many industries such as petroleum, natural gas, coal gas, water supply, thermal power generation, dredging engineering etc.
