Description

Technical Field

[0001] The utility model relates to the technical field of wound pipes, in particular to a PE wound pipe. Background Art

[0002] Polyethylene (PE) wound structure wall pipe is a general term for thermoplastic plastic round pipes with no internal pressure, which is mainly made of polyethylene resin and made by winding molding process.

[0003] At present, there are several main methods for connecting PE winding pipes during construction: 1. welding with a manual welding gun; 2. connection with hot melt tape or heat shrink tape; 3. connection with a holding tape; 4. hot melt welding, etc. These installation methods are generally inefficient.

[0004] For example, in the prior art, CN1587776A discloses a method for connecting wound pipes, wherein a certain thickness of the inner wall of one pipe at the connection part is cut away to form an inner groove shape, and a certain thickness of the outer wall of the other wound pipe is cut away to form an outer groove shape, and a layer of solid adhesive is applied to the surface of the pipe at the connection part or a sealing material such as a foaming agent is injected. The inner and outer grooves of the pipes are tightened against each other and the sealing material is used to achieve the effect of connection, fixation and sealing. Disassembly is relatively difficult, and installation requires waiting for the sealing material to fully adhere before proceeding to the next step, which takes a long time. Utility Model Content
