Abstract

The invention relates to a production apparatus and an extrusion technology of a novel clad pipe. The production apparatus comprises an extrusion production line apparatus for production of an inner layer and an external layer of an enhanced clad pipe, winders for winding and preheating a long fiber strip, a center locating frame for controlling a fibrous strip winding to cause tilt of an inner pipe, and a heating box for heating the inner pipe wound with the fibrous strip. According to the invention, two winders are configured between an inner pipe extrusion line and an external layer extrusion cladding die head and used alternately; when a fibrous strip on one winder is using up, the other winder is initiated rapidly to ensure continuous and stabilized production of the enhanced clad pipe. In the invention, a winding packaging technology is upgraded and reconstructed to combine with a cladding double-layer extrusion technology. A foreign complex technology requiring a special windercan be substituted to raise operation convenience, promote generalization of the technology and fill domestic technical blank of continuous fiber winding enhanced clad pipe. Therefore, the technologyof the invention is suitable for industrialized popularization.

Description

technical field

[0001] The invention belongs to pipeline production technology, and in particular relates to a production device of a novel composite pipe and an extrusion process thereof. Background technique

[0002] Traditional metal pipes have been exposed to corrosion, short life, high maintenance costs, poor sanitation and other shortcomings during use. The Ministry of Construction also has regulations to restrict the use of galvanized pipes. However, compared with metal pipes, plastic pipes also have some disadvantages, such as insufficient compressive strength and poor heat resistance, which greatly restrict their application. In order to combine the advantages of plastic pipes and metal pipes, composite pipes came into being. . At present, composite pipes are widely used in glass steel pipe (GRP), aluminum-plastic composite pipe, steel-plastic composite pipe, steel wire reinforced composite pipe, glass fiber reinforced composite pipe (F-PPR) and so on.
