Abstract

The invention discloses a production process and a product of a steel skeleton plastic composite pipe with a plastic end. The beneficial effect of the invention is that the problem that the steel skeleton plastic composite pipe is difficult to use hot-melt butt joint connection is solved by setting the injection molding end. The problem is that the steel skeleton plastic composite pipe with injection molding end provided by the present invention is connected by hot-melt butt joint connection, and the steel skeleton and the plastic end face connector are melted and connected as one, which completely solves the phenomenon of delamination and peeling off of the steel-plastic interface on the end face of the composite pipe. The reliability is greatly improved, and at the same time, it brings the advantages of low material consumption, easy manufacturing, low assembly cost, controllable welding pressure, little influence of human factors, and easy quality assurance.

Description

technical field

[0001] The invention relates to a forming process of a steel frame plastic composite pipe and its products, in particular to a production process of a steel frame plastic composite pipe with a plastic end and its product. Background technique

[0002] Steel skeleton composite pipe is a new type of pipe emerging in China in recent years. It is widely used in many fields such as petroleum, chemical industry, construction, shipbuilding, communication, electric power and underground gas pipeline. It is the best product to replace traditional galvanized pipe at present. Known as the green environmental protection pipe.

[0003] At present, the connection methods for steel skeleton composite pipes at home and abroad are basically flange bolt connection and electric melting sleeve connection, but the above connection methods have the following defects, as follows:

[0004] ①Flange connection

[0005] 1. It cannot be used for buried piping systems; 2. The connectin...
