Stainless steel lining technology
Trenchless Sewer Pipe Lining is the thin wall stainless steel tube as a carrier, welding molding, traction winch as the power of the stainless steel lining tube from one end of the pipeline to be repaired to the other end.After the interpenetration of the stainless steel pipe lining pipe, it is pressed and solidified by grouting to the gap between the lining pipe and the original pipeline under the condition of maintaining pressure.The formation of tight adhesion with the original pipe, smooth surface of the composite pipe.So as to achieve the purpose of strong pressure resistance, shock resistance and overall corrosion resistance, and extend the service life of the original pipeline for more than 50 years.
Research on basic theory of diagonal rolling
Trenchless Sewer Pipe Lining cross - rolling process has been widely used in the production of seamless steel tube.Cross - rolling mill has two - roll, three - roll system.Although the structure of the mill is different, the shape of the roll is different from the position of the roll in space, the geometric relationship between the adjustment parameters and the rolling process are basically the same in the deformation zone composed of the roll and the tube.
Research on basic theory of longitudinal rolling
Trenchless Sewer Pipe Lining rolling theory: the theoretical research of longitudinal tube rolling is mainly embodied in the continuous rolling process of floating mandrel and limiting mandrel in the continuous rolling mill2. Basic theory of tension reduction technology: two sets of tension reduction test prototypes with diameters of 76mm and 108mm manufactured in China were put into trial production in the early 1970s, which provided experience for the design and production process of tension reduction in China.
