Embodiment Construction

[0025] In order to better understand the purpose, structure and function of the present invention, a multi-reinforced steel-plastic composite pressure pipe transverse seam welding device and construction method of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0026] like figure 1 As shown, the present invention discloses a multi-reinforced steel-plastic composite pressure pipe transverse seam welding device, which includes a constant temperature fuser 1 and a hot melt plate 3 for heating the transverse seam. The hot melt plate 3 is connected and fixed by bolts 2 1 on the thermostatic hot melt plate.

[0027] As a preferred embodiment of the present invention, such as figure 1 As shown, the constant temperature fuser 1 has mounting holes, and can be fixed with the hot melt plate 3 by bolts 2 . The material of the hot melt plate is brass, which can quickly absorb the heat of the hot melter. The upper profile of the ...

Abstract

The invention discloses a multi-enhanced steel-plastic composite pressure pipe transverse seam welding device and a construction method, and belongs to the technical field of pipeline construction. A multi-reinforcement steel-plastic composite pressure pipe transverse seam welding device comprises a hot melting plate and a constant-temperature hot melting device, and the hot melting plate is fixedly connected to the constant-temperature hot melting device through bolts. The construction method of the welding device for the transverse seam of the multi-enhanced steel-plastic composite pressure pipe comprises the steps that the multi-enhanced steel-plastic composite pressure pipe is aligned and fixed, and after the welding device and the injection gun are preheated, injection welding is conducted on the transverse seam. According to the multi-enhanced steel-plastic composite pressure pipe transverse seam welding device, the construction method is simple and rapid, the welding quality is improved, the leakage problem of a transverse seam is thoroughly solved, and the operation loss is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a multi-reinforced steel-plastic composite pressure pipe transverse seam welding device and a construction method. Background technique [0002] The leakage in the field operation of multiple reinforced steel-plastic composite pressure pipes (hereinafter referred to as "multiple pipes") is mainly the leakage of transverse joints, which is formed after the joints of multiple pipes are completed, and the melting zone is wrapped with electric melting tape for welding. Leakage from the C-shaped mouth. The main reason is that when the injection gun is used to weld the transverse seam, the temperature of the pipe body is not enough to reach the melting temperature of polyethylene, so that the pipe body and the molten plastic of the injection gun cannot be completely integrated, forming a cavity, and the medium from After the pipe joint seeps out, it flows out...
