Upsetting Finished ERW Tubing

Tubing is used for delivering the oil and gas to ground from well bottom., incluing NU,EU and IJ tubing.
EU tubing: upsetting pipe ends, threading and coupling.
NU tubing: non-upsetting pipe ends; threading and coupling.
IJ tubing: inter upsetting at one end, external threading, external upsetting at another end , inter threading, direct connection without threading.

Our company designed centering claw to eliminate the original error, radial bounce of clamping disk reduced to 0.02mm from 0.15mm, enhanced the axiality of thread and body. We improved cutting cooing system to eliminate thermal deformation, improved tooling
lubrication, enhanced thread dimension precision and surface quality.

Our company has set up a new thread surface strengthening treatment line, after several tests, we got big succeed, no thread gluing appeared after 10 screwing up and off tests.

Through continuous quality and production control, the tubings manufactured by our company have even WT, good tensile, and smooth thread surface and sealing performance.
