Description
Technical Field

Background
The plastic pipe is generally made up by using synthetic resin, i.e. polyester as raw material, adding stabilizing agent, lubricant and plasticizer, etc. and adopting "plastic" method to make extrusion processing in pipe-making machine, and compared with the traditional cast iron pipe, galvanized steel pipe and cement pipe, etc. pipeline, it has the advantages of saving energy and saving material, protecting environment, light weight, high strength, resisting corrosion, smooth inner wall, easy and convenient to construct and maintain, and long service life, etc. and can be extensively used in building industry, municipal, industrial and agricultural fields of building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid conveying and agricultural irrigation, etc..
In practical application, the existing plastic pipe connection mode mainly comprises electric melting pipe fitting sleeving, socket joint type rubber ring connection, electric melting belt welding, flange butt joint, hot melting butt joint and the like. The electric melting pipe fitting sleeving is only suitable for connecting small-caliber pipes, and the electric melting pipe fitting has high cost; the socket rubber ring has higher connection cost, and the pressure bearing capacity of the pipe connection part is poor, so that the leakage is easy to occur; the electric melting belt is used for wrapping the end parts of the connected pipes together, and the electric melting belt is used for electrifying and welding, but the strength and the rigidity of a welding interface are lower, and the operation is difficult during welding; the flange butt joint is carried out after the end part of the pipe is welded with the flange plate, so that the process is complex and the cost is high.
Compared with the prior art, the hot-melting butt joint has the advantages that no connecting fitting is needed, the working procedure is simple, the cost is low, and the strength of the welding joint is superior to that of the pipe. When common plastic pipes are subjected to hot melting butt joint, a hot melting electric welding machine is generally adopted to heat the end parts of the pipes, so that after the pipe ends are melted, the end parts of two connected pieces are quickly attached, certain pressure is kept, and the purpose of welding is achieved through cooling. Because of the special structure of the continuous fiber reinforced pipe, the physical properties (melting point and the like) of the interlayer continuous fiber reinforced belt and the matrix material thermoplastic plastic are different, the continuous fiber reinforced pipe cannot be butted by adopting a common plastic pipe hot melting butt joint mode; the butt joint mode of the present continuous fiber reinforced pipe is that the connecting ends of the continuous fiber reinforced pipe are flanged firstly, after the flange is flanged, the end faces of the continuous fiber reinforced pipe are heated, then the end parts of the two continuous fiber reinforced pipes are attached rapidly, and the connecting mode is quick, but when the continuous fiber reinforced pipe is used subsequently, the connecting parts of the two continuous fiber reinforced pipes are easy to split, so that the leakage condition is easy to occur.
