API 5CT J55 Seamless Casing Tubing
API 5CT J55 seamless casing and tubing is a standard grade used primarily for shallow oil and gas drilling due to its cost-effectiveness. It features a minimum yield strength of 55,000 psi (approx. 379 MPa). This product is widely applied in the extraction of natural gas, coalbed methane, geothermal energy, and water wells. It serves to transport unrefined petroleum and gaseous fuel from the reservoir to the surface while withstanding downhole pressures and weights.
