Abstract
A reinforced type composite tube is characterized in that a plated steel strip layer (1), a glue layer (2) and an external plastic layer (3) are respectively arranged from the inside to the outside of the composite tube, and according to different application situations, a plated steel strip can be changed into a coated steel strip, an aluminium strip, a copper strip and a stainless steel strip, etc., and the materials of the external plastic layer can be common polyethylene (PE) plastics and common polypropylene (PP or PPR) plastics or high-temperature resistant plastics such as polyoxymethylene plastics, polyether plastics, polyester plastics, polysulfone plastics and fluoroplastic plastics, etc.
Description
Affiliated technical field:
The utility model relates to a kind of composite pipe material, the regular grade material of this composite pipe can be used for industries such as combustion gas, feedwater and carry normal temperature gas, liquid medium, and high temperature level material can be used for industries conveying high temperature liquid, gaseous mediums such as electric power, heating, exactly is a kind of enhancement mode composite pipe.
Background technique:
The tubing kind of China's gas industry use at present is a lot, and steel pipe, cast iron tube and plastic tube etc. are arranged.Wherein: the advantage of (1) cast iron tube (gray cast iron tube, ductile iron pipe) is: more corrosion-resistant, do not need preservative treatment.Shortcoming is: its tensile strength and impact resistance are low, property is crisp, interface easily leaks gas, keep in repair trouble.Internal surface is coarse relatively, and the conveyance fluid resistance is big, the operation cost height.Working life is short slightly.(2) polyethylene (PE) pipe advantage is: have good flexible, and also in light weight, pipeline can be coiled and snakelike laying, and the cut-through thing reduces joint quantity, easy construction.This pipeline has good anti-corrosion simultaneously, and the life-span is long, and the tightness of pipeline is better.Shortcoming is: the highest bearing capacity to delivery of fuel gas is restricted, is generally 0.1～0.4 MPa, less than the Applicable scope of steel pipe.Tensile strength is 1/5th of a steel pipe only simultaneously, bears pressure, shearing force, bending force, pulling force and all is not so good as steel pipe.(3) advantage of steel pipe is: the intensity height, and wall thickness is saved metal, and cost is relatively low, and plasticity is good, antidetonation, tensile strength is big, uses extensively in the rock gas high-pressure delivery.Shortcoming is: corrosion resistance is poor, take anti-corrosion measure, and working life is short, and not too convenient in the construction, joint weld place problem is more.
Summary of the invention:
Given this, the purpose of this utility model is the advantage of comprehensive metal tube and plastic tube, a kind of enhancement mode composite pipe is provided, this multiple tube inner tube is metal tube (1) (especially Chang Yong material is coated steel strips or the coated steel belt that price is low, intensity is good), is combined into pipe by heat-fusing glue layer (2) and outside plastic layer (3).Utilize metal strip to improve intensity, utilize plastics carrying and sealing.Liquid, gaseous mediums such as this composite pipe not only can transporting water, combustion gas.Change the material (changing polypropylene or high-temperature resistance plastices such as polyoxymethylene, polyethers, polyesters, poly-maple class and fluoroplastic into) of outer layer plastic by PE, can also be used to carry liquid, gaseous medium about 120 ℃, and this composite pipe amount of deflection is good, the bending convenient, intensity is high, make site operation simply easy, good seal and cost are low.The purpose of this utility model is to realize by such technological scheme principle:
The composite pipe inner tube is that metal tape docks welding or overlap joint or helix seam welding formation metal tube (1) by vertical masonry joint, squeezes deposited heat-fusing glue layer (2) on the metal tube surface then, then extrudes outer layer plastic tube (3) again.The beneficial effects of the utility model are:
1, the pipeline enhancement layer is a metal tape, and the tubing bearing capacity is improved, can attenuate outer layer plastic tube thickness.Reduce cost.
2, use different plastic materialss, pipeline can bear the high temperature less than 120～240 ℃, can be used for the high temperature occasion.
Description of drawings:
Fig. 1 is the utility model structure diagram.
The utility model is made up of inner layer metal pipe (1), glue-line (2), outer layer plastic tube (3).
Embodiment:
As shown in the figure: with interior pipe is zinc-plated (zinc) steel band metal tube (1), and outer layer plastic tube (3) is the PE pipe.This composite pipe can be used for combustion gas ground pipe laying.Because outer PE is thicker, composite pipe connects can adopt hot melt butt joint or flared fitting connection.
Claims (6)
1. enhancement mode composite pipe, it is characterized in that: composite pipe is respectively coated steel belt (1) (comprising the cover coat steel band), outer glue-line (2), outer plastic layer (3) from the inside to the outside.
2. a kind of enhancement mode composite pipe according to claim 1 is characterized in that: its outer layer plastic layer
(3) material is polyethylene (PE), polypropylene (PP or PPR) common plastics or polyoxymethylene, polyethers, polyesters, poly-maple class and fluoroplastic high-temperature resistance plastice.
3. a kind of enhancement mode composite pipe according to claim 1 is characterized in that: its coated steel strips (1) can be replaced by aluminium strip, copper strips, Stainless Steel Band according to different purposes occasions.
4. a kind of enhancement mode composite pipe according to claim 1 is characterized in that: its metal tape is that porous, pore-free surface are arranged.
5. a kind of enhancement mode composite pipe according to claim 1 is characterized in that: its metal tape adopts vertical masonry joint butt joint welding, overlap joint, welding, helix seam to be welded into tubulose.
6. a kind of enhancement mode composite pipe according to claim 1 is characterized in that: its Placement connects with hot melt butt joint, flare type joint.
