Two-step upsetting tubing and Green pipe
On the basis of regular API upsetting tubing, Changbao’s special upsetting products have two main directions: One is to satisfy customer’s requirements for premium connection processing, such as PH6 type integral joint connection; the other is for reuse of pipe body. Oil field operators must cut off damaged upsetting threading, but none-upsetting part could not ensure the joint connection strength. So two-step upsetting part can satisfy customer’s requirement for upsetting tubing re-use and save the cost.
