API 5CT Standard casing and tubing for oil production extraction
Description for 13Cr tubing pipe:
Tubing is a pipe used for the transportation of crude oil and natural gas from oil or gas layer to the
surface after drilling is completed. It is made to withstand the pressure generated from the extraction
process.
Tubing is manufactured in the same way as casing, except that an additional process known as
"upsetting" is applied to thicken the pipes.
Features:
1. Seamless oil pipe
2. Hot-rolling pipe
3. Size OD: 1.05”-4 1/2”
