Tubings

Product Outline

    Tubing is the special-purpose pipe that used in the oil, gas and water well to extract the oil, gas and water to the surface.
    The tubing conforms to API Specification 5CT, 5B and other related standards, authorized to use the API monogram.
    Standard, EUE and bimetal anticorrosion tubing are available at all sizes in grade J, N, C, L, T, P which all of them conform to API latest specification..

Technical characteristic

Adopting the advanced production line crack detecting, quenching, the continuous overall tempering and sand blasting processes to achieve higher mechanical strength ability with overall good performance.
1、The thread is cut by the special-purpose numerical control lathe which keeps the rod body still when cutting the threads. The special process could ensure the high precision of the thread with better reliability and life-span.
2、Coupling phosphor or copper coated to achieve good wearing-resistance ability and anti-thread gluing ability.
