Abstract
The utility model discloses a steel/plastic composite pipe used to carry fluid (liquid or gas), which is characterized in that: (1) The outer wall and the inner wall of the composite pipe are made from polymerized alkene plastics, while the center is steel pipes which is made of steel hoops by a means of longitudinally welding; the steel hoops are copper-plated (or aluminum-plated, zinc-plated, tin-plated) on the surfaces. The metal-plated steel pipes adhere to the inner, outer polymerized alkene plastics through polymer adhesives. (2) The composite pipe comprises seven coatings from inside out: A polymerized alkene plastic coating, an adhesive coating, a metal coating, a steel hoop, a metal coating, an adhesive coating and a polymerized alkene plastic coating. The utility model is characterized in the structure of the steel/plastic composite pipe, which has the advantages of low cost, light weight, high strength, good corrosion resistance, longer service life, as well as high interlayer adhesive force to make free of delamination, thus a great deal of synthetic performance can be achieved. The utility model makes full utilization of the special function from the copper-plated (or aluminum-plated, zinc-plated, tin-plated) steel hoops, the physical chemistry characteristics from plastics, and high strength from steel pipes, all of which compound a novel composite pipe with superior synthetic performance.
Description
The utility model relates to a kind of tubing of conveyance fluid, specifically relates to a kind of composite pipe.
The tubing of known technology has and adopts the clean steel material to make, and its shortcoming is that corrosion resistance is bad, and cost is expensive and heavy.Also there are the plastics of employing to make.But its intensity, resistance to pressure are relatively poor.
The purpose of this utility model just is to provide a kind of cost low, in light weight, and corrosion resistance is stronger, the steel-plastic composite pipe that the interlayer combination force is good.
For achieving the above object, the utility model adopts following scheme to realize; This composite pipe is made of seven-layer structure, and its inner and outer wall is made up of the polyolefin plastics; The steel pipe that the mesosphere adopts straight weld to be connected into for the Fixed width steel band of handling through copper coating (or aluminize, zinc-plated, zinc-plated); Adopt tackiness agent to closely bond between the steel pipe of band coating and inside and outside layer plastics.Its seven-layer structure is followed successively by from outside to inside: outer tube-polyolefin plastics; Outer adhesive-layer---polymer binder; Coating---copper coating, aluminium coat, zinc coating or tin coating; Steel pipe---straight seam welded steel pipe; Coating---copper coating, aluminium coat, zinc coating or tin coating; Interior adhesive-layer---polymer binder; Interior pipe---polyolefin plastics.
After adopting said structure, because the utility model provides a kind of composite pipe of novel seven-layer structure, the inner and outer wall of this pipe is made up of the polyolefin plastics; The steel pipe that the mesosphere adopts straight weld to be connected into for the Fixed width steel band of handling through copper coating (or aluminize, zinc-plated, zinc-plated); Adopt tackiness agent to closely bond between the steel pipe of band coating and inside and outside layer plastics.Its seven-layer structure is followed successively by from outside to inside: outer tube-polyolefin plastics; Outer adhesive-layer---polymer binder; Coating---copper coating, aluminium coat, zinc coating or tin coating; Steel pipe---straight seam welded steel pipe; Coating---copper coating, aluminium coat, zinc coating or tin coating; Interior adhesive-layer---polymer binder; Interior pipe---polyolefin plastics.
The steel-plastic composite pipe that the utility model provides, the steel band after copper facing (or aluminize, zinc-plated, zinc-plated) is handled that adopt in the mesosphere has the adhesion that improves tackiness agent, specific function such as corrosion-resistant, can improve the bonding strength between steel band and polyolefin plastics and the corrosion resistance of tubing greatly, make the performance of tubing more superior; And the cleaning of the steel strip surface after copper coating (or aluminize, zinc-plated, zinc-plated) is handled, dry, no greasy dirt, getting the raw materials ready, depositing when being convenient to produce, surface preparation operations such as steel strip surface rust cleaning in the plain carbon steel plastic composite pipe manufacture process, cleaning, oven dry have been saved, can drop into by reduction equipment, significantly improved the manufacturability that tubing is made.Therefore the novel tube that steel-plastic composite pipe is low, in light weight, the withstand voltage height of a kind of cost, corrosion resistance is stronger, the interlayer combination force is fabulous, combination property is more superior that provides of the utility model.Can be widely used in the conveying of conveying, high-pressure liquid of municipal engineering plumbing, water supply pipe, coal gas, rock gas, liquid gas, oil, chemical industry fluid and heat supply heating with each fields such as pipe-line systems.
Be further described below in conjunction with drawings and Examples.
Figure one is the utility model structural representation.
Shown in figure one, steel-plastic composite pipe of the present utility model is made of seven-layer structure, and it is from outside to inside; 1 is outer tube-polyolefin plastics; 2 is outer adhesive-layer---polymer binder; 3 is serving---copper coating, aluminium coat, zinc coating or tin coating; 4 is interior adhesive-layer---polymer binder; 5 is interior coating---copper coating, aluminium coat, zinc coating or tin coating; 6 is internal plastic tube---the polyolefin plastics; 7 is steel pipe---straight seam welded steel pipe.
Claims (1)
1, a kind of coated steel plastic composite, it is characterized in that: composite pipe outer wall and inwall are the polyolefin plastics, the centre is the steel pipe that is welded through vertical masonry joint through the steel band that copper coating (aluminize, zinc-plated, zinc-plated) is handled, and the steel pipe of band coating is bonding by polymer binder and inside and outside strata hydrocarbon alkene plastics; Composite pipe is followed successively by from inside to outside: polyolefin plastic layer, sticker layer, coating, steel band, coating, sticker layer, polyolefin plastic layer be totally 7 layers of structure.
