The main production process of high-pressure steel pipe: billet heating, perforated tube, pipe extension.

High-pressure steel pipe rolling, pipe sizing, reducing pipe, cooling and finishing steel or can be said to be heated perforated steel embryo hot rolled pickling spray head cut cold drawn carbon burning packaging products manufacturing a seamless steel pipe the method comprising: setting will have more of a rolling mill roll stand, to each different configuration of multiple consecutive rolling direction of the mandrel mill, in such a manufacturing production line rolling of seamless steel pipe After both end positions of each axis system, the wall thickness was measured in the pipe circumferential direction after rolling on the multi-point, based on the measurement result, at least control the mandrel mill of the final rolling mill roll the base station , so uneven wall thickness to a minimum.

Maintenance of high-pressure steel pipe is very simple, as long as the inner tube with a cleaning agent residues such as methanol wash cycle back and forth constantly, until it is determined after a clean, then clean the cleaning agent once, the tube is best to leave some cleaning agents, to prevent the event not clean, and produce plug tube. When the high-pressure pipe is strictly prohibited pack folded or 90 degrees or hanging close.
