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. • Drifting test. to inspect the straightness of the pipes and to determine if any protrusions exist along the inner walls • Hardness and pressure test. to ensure that the pipes can withstand the requisite external pressure and exhibits the required hardness before final coating. • size and surface test to make sure that there are no visible defects and conform to the intended parameters and lengths Package&delivery Small size bundles with steel strips, big size in bulk, with plastic cap to protect thread ends, seaworthy packaging; Payment L/C,T/T, One touch etc or as your requirement.
