During the process, we have rigorous quality control system ,it includes: <br />
• Chemical composition and mechanical<br />
• Thread inspection <br />
• Hydro static test.<br />
Pipes are rolled onto a hydro static testing machine where water is pumped into the pipes to ensure that the pipes can withstand the requisite internal pressure and to confirm that there is no leakage.<br />
• Drifting test.<br />
to inspect the straightness of the pipes and to determine if any protrusions exist along the inner walls<br />
• Hardness and pressure test. to ensure that the pipes can withstand the requisite external pressure and exhibits the required hardness before final coating.<br />
• size and surface test<br />
to make sure that there are no visible defects and conform to the intended parameters and lengths<span style="font-size:16px;"><br />
