Description
Technical field
The utility model relates to steel-plastic composite pressure pipe, relates in particular to a kind of five-layer structure steel-plastic composite pressure pipe.
Background technique
The pipeline of carrying fluid to use at present mostly is single plastic tube and steel pipe.Although steel pipe has the advantage that rigidity is large, intensity is high, the inside and outside easy fouling of tube wall is got rusty, and causes the damage of the pollution of medium in the pipe and pipeline fast.Plastic tube has the advantages such as resistance to chemical corrosion friction factor good, less scaling, when carrying fluid is little, but has the deficiencies such as intensity is little, flexible, creep, joint easy to leak.
Be 992161338 in China Patent No., notice of authorization day be February 28 in 1996 day, be called public a kind of plastic tube of three-decker in the patent documentation of " plastic pipe ".Although this pipe makes moderate progress to the deficiency of above-described plastic tube, still do not have the advantage of steel pipe.
Be 2010205823892 in China Patent No., notice of authorization day be June 1 in 2011 day, be called in the patent documentation of " outer zinc-plated internal plastic coating composite steel tube " and disclose a kind of pipe.This pipe by in the steel pipe internal-surface plastic-coated forms, mould the layer, at the zinc-plated formation zinc of outer surface of steel tube layer, so that pipe has the advantage of steel pipe and has antiseptic property.
The composite pipe of the steel-plastic structure of above structure has the following disadvantages, and moulds layer in forming in steel pipe in the mode that is coated with, and is very inconvenient during production, and is coated with and the layer of moulding that forms comes off easily, less than carry out effectively anticorrosion and prevent from managing in the medium that flows through contaminated.The outer surface of steel pipe carries out anticorrosion with zinc coat, collide slightly then that the zinc layer comes off easily, do not have effective antisepsis, after steel pipe is coated with the zinc layer, in welding process, need the zinc layer on surface is wiped off just and can be welded, brought great inconvenience for production and use work.
The model utility content
The utility model provides for a kind of and has had steel pipe concurrently and mould pipe five-layer structure steel-plastic composite pressure pipe superiority and that be convenient to processing, has solved existing pipe production and processing inconvenience and the poor problem of antiseptic effect that has steel pipe and mould the characteristic of pipe.
Above technical problem solves by following technical proposal: a kind of five-layer structure steel-plastic composite pressure pipe, comprise cross section be open annular stainless steel tank, be located in the stainless steel tank in mould layer, be used for will in mould inner glue layer that layer and stainless steel tank bond together, the opening of the stainless steel tank of moulding layer in being equipped with carried out weld line that welded closure forms, be set in the outer outer plastic layer of stainless steel tank and weld line and be used for outer plastic layer with stainless steel tank and the two outer glue-line that bonds together of weld line.Be made into stainless steel tank by Stainless Steel Band, then the outer surface that squeezes out is scribbled glue in mould the layer be inserted in the stainless steel tank, the opening welding of then welding stainless steel tank by stainless steel firmly forms weld line, be coated with gluing at the good stainless steel tank of welding again, then put outer plastic layer, namely finish making of the present utility model.
As preferably, the cross section of described weld line is narrow trapezoidal in wide the inner, outer end.Since weld line when being the soldering stainless steel steel tank opening at stainless steel tank form, the cross section of weld line is shape wide outside and narrow inside so that guarantee can fill the full gate mouth fully along the wall thickness direction of stainless steel tank during welding, weld strength is good.
As preferably, the internal surface of described stainless steel tank is provided with some the first pits, and described inner glue layer is provided with the first projection that is filled in the first pit, and described the first projection is structure as a whole with inner glue layer.Mould layer in effectively preventing with coming off vertically between the stainless steel tank.
As preferably, the outer surface of described stainless steel tank is provided with some the second pits, and described outer glue-line is provided with the second projection that is filled in the second pit, and described the second projection is structure as a whole with outer glue-line.Can prevent effectively that outer plastic layer is with coming off vertically between the stainless steel tank.
As preferably, mould the thickness of layer less than the thickness of outer plastic layer in described.The characteristic of moulding pipe can be guaranteed the utlity model has, the consumption of plastics can be reduced simultaneously.The inside of steel layer can not be subject to local collision, moulds in therefore that the thin thickness of layer also can not occur ftractureing and phenomenon that cause stainless steel tank to expose produces.And outside be subject to easily extraneous collision, so in mould layer thickness to be lower than the Thickness Design of outer plastic layer reasonable.
The utlity model has following advantage, inside and outside the stainless steel lining that is consisted of by stainless steel tank and weld line, all arrange and mould layer and consist of the utility model so that the utility model has steel pipe and the superiority of moulding pipe concurrently, than inner plastic-blasting, in mould a layer difficult drop-off; Mould mode that layer moulds than lining in this kind structural type forms and mould layer in forming, it is convenient to add man-hour; The position of steel-plastic composite pressure pipe pressure-bearing effect is to be positioned to mould the middle steel layer of layer, stainless steel is compared with common galvanized steel has higher Young's modulus, therefore bearing capacity of the present utility model is stronger, can accomplish that under the condition of equal nominal pressure and nominal outside diameter moulding the compounding pressure layer than the steel that adopts the galvanized steel layer accomplishes to have thinner wall thickness, quality is lighter, construction is convenient, and hydraulic loss is less; Adopt stainless steel lining do not exist because of the steam seepage cause the phenomenon of corrosion, than the tin-coated steel layer, can save the operation of the layer that dezincifies during welding, the convenience during production and application is good; When carrying out argon arc welding, need not use the helium protection, reduced cost of production; After tubing completes, do not need the tubing tangent plane is carried out plastic packaging, saved the operation that when pipeline connects, will repair to the plastic packaging face type, improved the convenience when using.
