Material: It is usually made of high-strength alloy steel or carbon steel, such as J55, N80, P110 and other steel grades. These materials have excellent toughness, corrosion resistance and fatigue resistance, and can adapt to different underground working environments.
Characteristics: The thickened oil pipe has high strength and anti-crush capacity, and can withstand the high pressure, high temperature and complex stress in the underground during the oil extraction process. Meanwhile, due to the increased wall thickness of the thickened part, its wear resistance is also enhanced, reducing problems such as leakage caused by wear during the use of the oil pipe and prolonging its service life.
