Pipe connection clamp, electromagnetic induction pipe connection device and pipeline electromagnetic pipe connection method

Abstract

The invention relates to a pipe connection clamp which is characterized by comprising a housing in a hoop structure, wherein the housing comprises two hoop plates which are folded and connected, one end of one hoop plate is hinged with one end of the other hoop plate, and a handle which is convenient to grip is extended from the hinge joint of the two hoop plates; and a magnetic layer, a silica gel layer and a magnetic wire coil are sequentially arranged on the inner side of each hoop plate to the outer side along the bottom of the plate, and the magnetic wire coils are electrically connected with the outside. The invention aims at providing a pipe connection clamp which is simple to use, simple to mount and good in anti-corrosion performance and can firmly connect metal / plastic composite pipes, an electromagnetic induction pipe connection device using the pipe connection clamp and a pipeline electromagnetic pipe connection method. By using the invention, pipe fittings and pipes can be effectively combined together, a metal layer is arranged in the plastics to achieve the effects of permanent seepage prevention and absolute corrosion prevention, the mounting process is convenient, and the connection is firm.

Description

technical field [0001] The invention relates to the field of pipe connection equipment, in particular to a pipe connection machine for metal / plastic composite pipes, in particular to a pipe connection fixture, electromagnetic induction pipe connection equipment and a pipeline electromagnetic pipe connection method. Background technique [0002] Metal / plastic composite pipes, such as steel-plastic composite pipes, iron-plastic composite pipes, etc., taking steel-plastic composite pipes as an example, the products use seamless steel pipes and welded steel pipes as machine pipes, and the plastic is generally high-density polyethylene. The strip steel in the first layer is airtight, so this steel-plastic composite pipe has an oxygen barrier effect at the same time, and can be directly used in direct drinking water projects, and its inner and outer layers are made of plastic material, which has very good corrosion resistance. Such excellent performance makes steel-plastic composi...

Problems solved by technology

[0003] When these metal / plastic composite pipes are connected to the pipe fittings, the electric furnace wire is usually used to heat the round iron to the concave and convex, and then the pipe is inserted into the iron concave and convex groove to melt the plastic and remove the pipe and pipe fittings. Steel-plastic composite pipes, cast iron-lined plastic pipes, and stainless steel-lined plastic pipes are difficult to weld
