Description

technical field [0001] The invention relates to the technical field of bimetallic pipe processing, in particular to a bimetallic pipe hydraulic composite equipment control system. Background technique [0002] In recent years, due to the low cost of bimetallic pipes and the advantages of corrosion-resistant inner pipes, no scaling, small flow resistance and high strength and reliability of outer pipes, bimetallic composite pipes have been widely used in civil water, gas and oil transportation. , industrial chemicals and other industries are widely used. After the bimetallic composite pipe penetrates into the outer base pipe, pressurized lamination is required to make the outer base pipe and the inner liner pipe stick together. At present, mechanical extrusion and hydrostatic hydraulic pressure are mainly used for material compounding. Mechanical extrusion compounding adopts a mechanical expansion device to carry out extrusion compounding on the inner liner. Hydrostatic hyd...

AI Technical Summary

Problems solved by technology

[0003] However, in the process of processing bimetallic pipes by hydraulic lamination, there are the following problems: 1. During the hydraulic lamination process, due to the leakage of pressurized water, the pressure is unstable, but it is impossible to monitor the water pressure in real time and adjust the water pressure in time. 2. When the hydraulic composite equipment seals the port of the bimetallic tube, the sealing rings at both ends of the composite tube are fixed in size and cannot be adjusted. They can only be sealed by pushing in the machine. Among them, the production efficiency is low, and the long-term use causes the sealing ring to wear and cause the combination to be loose, resulting in the leakage of pressurized water; 3. Due to the difference in the performance of the base pipe, sometimes local deformation of the pipe may occur, and even blasting and safety accidents may occur , causing staff injury and equipment damage, which is extremely dangerous in industry
