Steel-plastic composite pipe lining device and operation method thereof

Abstract

The invention provides a steel-plastic composite pipe lining device and an operation method thereof. The device comprises a rack (1), an electromagnetic induction coil (2), a top pipe and an inflation device (3), wherein a steel-plastic composite pipe is positioned inside the rack (1); the top pipe and the inflation device (3) are arranged on the sides of one end or two ends of the steel-plastic composite pipe, and can fix an outer-layer steel pipe and an inner-layer plastic pipe of the steel-plastic composite pipe; and the electromagnetic induction coil (2) is also arranged inside the rack (1) and can be sleeved on the periphery of the steel-plastic composite pipe to move back and forth. The steel-plastic composite pipe lining device has the advantages of directly and evenly heating the steel pipe, along with low energy consumption and loss and high production efficiency.

Description

technical field [0001] The invention belongs to the field of pipe equipment, in particular to a steel-plastic composite pipe lining equipment and an operating method of the equipment. technical background [0002] Traditional galvanized pipes and cast iron pipes have been used in my country's water pipeline network supporting pipes, but these pipes are prone to produce yellow rust, white turbidity, scale and other toxic and harmful substances during use, which seriously endanger people's health. With the rapid development of the economy and the improvement of living standards, people's existing drinking water quality requirements are becoming increasingly urgent. The State Council and the Ministry of Construction have also successively issued restrictions on the use of galvanized pipes in drinking water pipe networks. Therefore, it is necessary to develop a new type of pipe suitable for the requirements of the drinking water pipe network. [0003] Chinese Patent Publication...

AI Technical Summary

Problems solved by technology

The equipment disclosed in this patent uses steam heating to transfer to the steel pipe, which is likely to cause uneven inner surface of the pipe due to uneven heating and air between the interlayers, and the use of steam heating results in large energy loss and low production efficiency.
