Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding device for HDPE steel belt reinforced spiral corrugated pipes. Background Art

[0002] HDPE steel belt reinforced spiral corrugated pipe is a new type of plastic pressure pipe, which combines the corrosion resistance of high-density polyethylene (HDPE) and the high strength of steel belts, and is suitable for various drainage and sewage projects. The HDPE steel belt reinforced spiral corrugated pipe uses polyethylene as the matrix material, and the steel belt with surface-coated adhesive resin is formed into a waveform inside as the main support structure, and is compounded with the polyethylene material into an integral double-wall spiral corrugated pipe. This structure enables the pipe to have a relatively high ring stiffness and good impact resistance. There are various connection methods for HDPE steel belt reinforced spiral corrugated pipes, including electrofusion connection, heat shrinkable belt connection, welding or a combination of multiple connections, ensuring firm connection and zero leakage. When welding HDPE steel belt reinforced spiral corrugated pipes, it is necessary to first butt the HDPE steel belt reinforced spiral corrugated pipes, and the butt process is more cumbersome and complex.
