A socket-reinforced composite plastic pipe and its manufacturing process

Abstract

A socket-reinforced composite plastic pipe and its manufacturing process. It includes a pipe wall and a socket. A protruding ring is provided at the inner diameter of the L-length pipe wall at the end of the socket, and plastic resin mixed ingredients are used as raw materials. The technical scheme of making products under the synchronous control of drying machine, extruder, die head, mold, vacuum box, spray box, tractor, cutting machine and other equipment; it overcomes the existing polyethylene resin composite pipe-PE pipe, Because the cross-sectional strength and rigidity of the butt joint of the pipe socket cannot bear the pressure inside the pipe, the pipe wall will bulge, deform, and even crack, resulting in water leakage and air leakage in the pipe, resulting in difficulties in maintenance of water supply, gas supply, and liquid supply systems, serious loss of resources and gas consumption. Leakage causes defects such as environmental pollution; it is suitable for connecting pipes in various water transmission projects and gas transmission projects; it is especially suitable for thickening and strengthening sockets of plastic pipes such as PE, PVC-U, and PVC-M.

Description

technical field [0001] The invention relates to a socket-reinforced composite plastic pipe and its manufacturing process. Background technique [0002] Existing polyethylene resin composite pipe, commonly known as PE pipe, has the characteristics of easy construction and installation, and is applied in the water supply and drainage and gas transmission industries. However, in the process of construction and installation, most of them adopt the butt joint method of electric fusion pipe fittings. This construction and installation method is affected by the environmental factors of the construction site and personal operation skills. The mutual lateral movement and dislocation of the two socket pipe walls during welding The non-"roundness" of the butt joint of the pipe socket increases and it is difficult to ensure the quality of the butt joint. The "roundness" is two concentric circles with a radius difference of a certain value on any normal section of the socket butt joint; ...

However, in the process of construction and installation, most of them adopt the butt joint method of electric fusion pipe fittings. This construction and installation method is affected by the environmental factors of the construction site and personal operation skills. The mutual lateral movement and dislocation of the two socket pipe walls during welding The non-"roundness" of the butt joint of the pipe socket increases and it is difficult to ensure the quality of the butt joint. The "roundness" is two concentric circles with a radius difference of a certain value on any normal section of the socket butt joint; especially for For pipes with lower pressure ratings (that is, thinner pipe walls), it will be more difficult to ensure the quality of the butt joint due to the non-"roundness" of the pipe socket joint; as a result, the cross-sectional strength and rigidity of the pipe socket joint will not be able to bear The pressure inside the pipe causes the pipe wall to bulge, deform, and even crack, resulting in water and air leakage in the pipe, resulting in difficulties in maintaining water, gas, and liquid supply systems, serious resource losses, and environmental pollution caused by gas leakage
