Abstract

The invention discloses a composite pipe with a metal pipe coated by resin, and a manufacturing method and a construction method thereof. The composite pipe is prepared by forming a bonding layer and a resin layer on the outer surface of a metal pipe. Even if the composite pipe is coiled into a ring shape, the composite pipe is not damaged, and the cross section is maintained to be round; even if the composite pipe is restored to a straight pipe for construction convenience, separation or wrinkle is not generated. Therefore, the composite pipe product has the advantages of good construction property and transportation property.

Description

technical field [0001] The present invention relates to a resin-metal composite pipe (Composite pipe having metal pipe coated with resin), and more particularly, to a pipe wound in a ring shape (rolled in a roll) while maintaining a circular section of the pipe. shape) and make it bend, so that the length can be made longer, so that it can be easily transported and a resin-metal composite pipe with good workability. In addition, the present invention also relates to a method of manufacturing the resin-metal composite pipe and a construction method thereof. Background technique [0002] Generally speaking, high-corrosion-resistant metal pipes such as stainless steel pipes have many advantages, but their relatively expensive materials lead to an increase in the unit price of the product. In addition, the metal pipe has certain limitations in bending and other forming aspects, which causes many difficulties during construction, so it can only be manufactured with straight pipe...
