Problems solved by technology

This patent has a simple structure and is easy to process and manufacture. However, if the steel wire mesh at the end of the composite pipe after cutting is exposed, it is easy to cause rust and deformation of the steel wire mesh. However, at present, it is necessary to seal it. However, this link is often ignored in actual operation, and there is no corresponding sealing equipment

Embodiment Construction

[0020] The invention discloses a sealing method for a plastic composite pipe with a steel wire frame, which uses the plastic sealing method of the pipe itself, first heats the port of the composite pipe, and then wraps the steel wire with the plastic that is turned inside out after the composite pipe is heated by an external force. Wherein, after the port of the composite pipe is heated, the composite pipe is put into a mold with a good specification, and the composite pipe or mold is moved to restore the plastic flanged out after heating, and then the composite pipe and mold are moved to repair The end of the good pipe is squeezed against a pre-prepared flat plate, and after cooling, the composite pipe is taken out to complete the sealing process. The process of putting the composite pipe into the mold with a good specification is to cover the outer wall of the composite pipe through the outer mold, and to restore and shape the plastic that has been turned out of the composite...

Abstract

The invention discloses a method and a device for sealing steel wire framework plastic composite pipe. The method comprises the following steps of: heating end opening of a composite pipe by a way of self plastic sealing of pipe material, and wrapping a steel wire with plastics turned out from inside and outside of the heated composite pipe by effect of external force. The device comprises a sealing rack and a mould disposed on the sealing rack for fixing the composite pipe; and a heating plate corresponding to the end opening of the composite pipe is disposed out of the mould. The plastics of the pipe material can be wrapped on the steel wire for sealing, and good promotional value is realized.

Description

technical field [0001] The invention relates to the technical field of composite pipes, in particular to a steel wire skeleton plastic composite pipe. Background technique [0002] Steel mesh skeleton plastic composite pipe is a new type of steel skeleton plastic composite pipe that has been improved. This kind of pipe is also called SRTP pipe. This new type of pipe is made of high-strength plastic steel wire mesh skeleton and thermoplastic polyethylene as raw materials. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. The modified bonding resin tightly connects the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has an excellent composite effect. Because the high-strength steel wire reinforcement is wrapped in continuous thermoplastic, this composite pipe overcomes the respective shortcomings of steel pipes and plastic pipes, while maintaining the respective advantages of steel...
