Abstract
The utility model provides a thermo welded metal-plastic multiple-unit tube, a tube body of which comprises an internal layer and an external layer. The inner layer tube body is a metal sleeve, the outer layer tube body is a plastic tube and a hot-melt adhesive layer is arranged between the internal tube body and the external tube body. The outer surface of the inner layer metal sleeve is provided with napping or rough pressed traces. The rough traces are pulled into a rectilinear figure, a coiled figure or irregular line traces. The rough traces are pressed into permeate small holes, non-permeate small bulges or foveolas. The materials of the outer layer plastic tube body are fusible or electrically fused(PP-R, PP-B and PP-H)polypropylene plastic, polyethylene PE and PERT plastic, polybutene PB plastic or nylon plastic. The inner layer metal tube body is a stainless steel tube, a welded tube or a seamless tube of an aluminum tube or a welded tube of a copper tube. The metal plastic internal and external tube bodies combine the advantages of the metal tube and the plastic tube, such as double anticorrosion, light weight, high strength and low cost. The internal tube body and the external tube body are combined firmly; the whole tube body has good integrity and the inner tube body and the outer tube body are not easy to peel off; the utility model is suitable for transmitting water or other liquid.
Description
Technical field
The utility model relates to a kind of pipeline of conveyance fluid.
Background technique
The pipeline of existing conveyance fluid has metal tube, plastic tube and aluminium-plastic composite pipe.Metal tube good rigidly, quality are greatly, the plastic tube anti-corrosive properties are good, fire retardancy is poor, and two kinds of pipelines respectively have pluses and minuses.The inside and outside body of aluminium-plastic composite pipe is in conjunction with insecure, and the body integrity is bad, and inside and outside body easily breaks away from.
Technology contents
The utility model will solve metal, plastic pipe respectively pluses and minuses, and the problem that can not take into account solves the problem that the inside and outside body of composite metal-plastic pipe easily breaks away from.
