Polyethylene steel and plastic composite winding pipe

Abstract

The invention relates to a polyethylene steel and plastic composite winding pipe. A pipe body of the composite winding pipe is wound and formed by steel and plastic composite plate belt materials, the adjacent steel and plastic composite plate belt materials are welded by adopting a metal welding process, a polyethylene resin covering layer is covered on a welding line between the adjacent steel and plastic composite plate belt materials, and V-shaped reinforced steel ribs are wound and embedded between T-shaped caps arranged at the outer wall of the pipe body. The pipe body of the polyethylene steel and plastic composite winding pipe is wound and formed by the steel and plastic composite plate belt materials, the complete pipe is welded by the steel belts inside the pipe wall to be used as the internal pressure resistance support pipe, the internal pressure resistance level of a large-caliber plastic pipe is greatly improved, meanwhile, compared with a plastic pipe, the polyethylene steel and plastic composite winding pipe has higher annular rigidity, the pipe wall of the steel belt welding pipe is completely covered in the polyethylene resin, the corrosion resistance performance is greatly improved, the outer wall adopts the V-shaped reinforced steel bars as a main body for realizing the effect of supporting the external pressure, on the use premise of greatly saving steel and plastics, the annular rigidity of the integral pipe material is greatly improved, in addition, the weight of the integral pipe materials is light, and the construction and the installation are favorably realized.

Description

technical field [0001] The invention belongs to the field of pipe manufacturing, in particular to a polyethylene steel-plastic composite winding pipe. Background technique [0002] At present, cement pipes and metal pipes are still the main products of large-diameter water supply and drainage pipes. The advantage is that cement pipes and metal pipes can still maintain high rigidity requirements under larger diameters, but the disadvantages are more prominent, mainly because they are not corrosion-resistant and easy to Leakage, heavy weight, difficult construction, etc. For plastic materials, due to their own creep and low modulus, their application in the field of large-diameter pipes is greatly restricted, especially large-diameter pipes. Caliber water supply pipes, such as water supply pipes with a diameter of more than 2000mm, are basically not available in plastic pipes. To use plastic pipes to achieve the purpose of large-diameter water supply and drainage requires a la...

Problems solved by technology

[0002] At present, cement pipes and metal pipes are still the main products of large-diameter water supply and drainage pipes. The advantage is that cement pipes and metal pipes can still maintain high rigidity requirements under larger diameters, but the disadvantages are more prominent, mainly because they are not corrosion-resistant and easy to Leakage, heavy weight, difficult construction, etc. For plastic materials, due to their own creep and low modulus, their application in the field of large-diameter pipes is greatly restricted, especially large-diameter pipes. Caliber water supply pipes, such as water supply pipes with a diameter of 2000mm or more, are basically not available in plastic pipes. To use plastic pipes to achieve the purpose of large-diameter water supply and drainage requires a large amount of raw material resources, which is not in line with the national policy of saving energy and reducing energy consumption.
