Product Detail
Tubing is a key component in oil extraction operations.Processed into tubes with specific diameters and wall thicknesses through an advanced hot rolling process. In order to enhance the corrosion resistance, the tubing will be treated with a special anti-corrosion coating, effectively resisting the erosion of complex media in the oil well. These processes guarantee the long-term stable operation of the tubing in the harsh oil well environment.
Manufacturing Process
API 5CT J55 is a steel pipe made by either a seamless process or an EW welding process.
Common EW processes include ERW and EFW.
ERW (Electric Resistance Welding) is typically used for tubes with thinner walls, while EFW (Electrofusion Welding) is used for tubes with thicker walls, which are able to withstand higher pressures.
Coupling materials, coupling blanks and coupling materials must be manufactured using a seamless process.
