Groove connected PE wound corrugated pipe

Abstract

The invention provides a groove connected PE wound corrugated pipe. The groove connected PE wound corrugated pipe comprises a plastic forming strip, connecting grooves, an adhesive glue injecting face, an annular locking plunger and a corrugated pipe. Two connecting grooves are separately formed in the end surfaces of left and right sides of the plastic forming strip and the corrugated pipe is mounted out of the plastic forming strip in a sleeving mode, and two ends of the plastic forming strip are of hollow structures; the adhesive glue injecting face is located on the inner wall of the corrugated pipe and is connected to the annular locking plunger, and the annular locking plunger is located in the corrugated pipe. The inner wall of the wound corrugated pipe is supported favorably, the internal anti-pressure ability of the wound corrugated pipe is enhanced, and the condition that circulation in the corrugated pipe is affected as the wound corrugated pipe is flattened and deformed because the corrugated pipe is extruded by an external force is avoided. By using the connecting grooves and the annular locking plunger, the plastic forming strip mounted in the wound corrugated pipe can be connected together to improve the tensile coefficient and the anti-break coefficient of the wound corrugated pipe, so that the wound corrugated pipe is steadier and more reliable.

Description

technical field [0001] The invention belongs to the technical field of winding corrugated pipes, and more specifically relates to a grooved connection PE winding corrugated pipe. Background technique [0002] The spiral corrugated pipe is first heated and drawn into a strip-shaped profile of PE plastic, and then heated and melted PE plastic is injected into the gap between the strip-shaped windings during the pipe-making process, and the strip-shaped polyethylene plastic is bonded together. , forming a winding corrugated pipe. [0003] The inventors found that the existing wound corrugated pipes have poor compression resistance and are prone to damage when squeezed, which affects the use effect of the wound corrugated pipes; and when the pipes are exposed to cold and hot environments, they are prone to rupture at the joints Or fracture, resulting in shortcomings and weaknesses such as short service life of the pipe, making it difficult to meet the needs of customers.
