Tubing basic infomation

Tubing
 
StandardAPI SPEC 5CT Standard. 
 
Use: Seamless steel tubes for oil casing and tubing in oil and gas well. Tubing is mounted in the production casing after the oil well is dig and cemented, it is seamless pipe to transport oil gas to ground 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
