External upset tubing

Tubing

Standard：API SPEC 5CT Standard.

Use: Seamless steel tubes for oil casing and tubing in oil and gas well. Tubing is mounted in the produc tion casing after the oil well is dig and cemented, it is seamless pipe to transport oil gas to grou nd surface.

Steel grade: J55, K55, N80, L80, C90, T95, P110, Q125

Size: 4 1/2”~20” for Seamless Casing

1.05”~4 1/2” for Seamless Tubing

Length: R1/R2/R3
