Abstract
A plastic-steel coated pipe is composed if internal plastic pipe, adhesive layer, steel pipe layer, thermosol layer and plastic layer. Its manufacture technology includes such steps as cleaning steel pipe, coating adhesive on external surface of plastic pipe, inserting the plastic pipe in steel one, heating at 150-350 deg.C, coating thermosol on its external surface, cooling until the thermosol becomes semi-molten state, and injecting plastic layer. Its advantages include high strength and corrosion and rust resistance and smooth surface.
Description
The present invention relates to tubing, particularly relate to the plastic steel composite pipe material, and the manufacture method of plastic steel composite pipe material, this tubing is mainly used in that delivery temperature is no more than 80 ℃ water, oil and other fluid under the low pressure.
Existing low-pressure fluid is carried and use tubing, to, waste pipe, generally adopts metal tube or plastic tube as life, and oil feed pipe then is a metal tube.The characteristics of metal pipe are that mechanical strength is good, can not be out of shape, but that its shortcoming is a tube wall are coarse that the easy fouling of tube wall causes caliber to dwindle, and it is not smooth to flow; Though be that processing is waited through zinc-plated in the surface on the other hand, but still can get rusty.The characteristics of plastic tube are inner wall smooths, are not easy fouling, guarantee in the pipe smoothly, but that its shortcoming is a mechanical strength is relatively poor, regular meeting's bending deflection.
The purpose of this invention is to provide and a kind ofly combine, and plastic steel composite pipe material processing technology is provided, make the tubing intensity of production good with steel pipe and plastic pipe layer, carry smooth, non-corrosive.
The technological scheme of plastic-steel cladding tubing of the present invention is: interior plastic pipe layer is arranged; The adhesive layer that interior plastic pipe layer is outer, adhesive layer is outward the steel pipe layer, steel pipe layer heat in the exterior melten gel layer, heat-fusing glue layer is shaped on the plastics cladding outward.
The manufacture method of plastic-steel cladding tubing of the present invention, getting prefabricated steel pipe cleans, other gets plastic tube, outer wall at plastic tube is squeezed into binder, insert in the steel pipe squeezing the plastic tube that binder is arranged, the tubing that the interior plastic pipe layer and the steel pipe layer of combination are formed drops in the heating chamber, the temperature of heating chamber is controlled at 150 ℃-350 ℃, in 30 minutes heating times, take out the back and squeeze into hot melt adhesive at outer pipe wall, make hot melt adhesive be cooled to the fritting state, outside the heat-fusing glue layer of fritting state, annotate system plastics cladding again.
The manufacture method of plastic-steel cladding tubing of the present invention, raw material of plastic pipe layer and plastics cladding is polyethylene or other plastics such as PVC or polypropylene in it.
The invention discloses the manufacture method of a kind of plastic-steel cladding tubing and plastic-steel cladding tubing, all clad plastic layer in steel pipe inner and outer, make tubing keep the mechanical strength of steel pipe, bring into play plastic layer non-corrosive, corrosion-resistant again, the smooth smoothness of pipe, characteristics such as non-scaling; And squeezing between each composite bed has adhesive layer and heat-fusing glue layer, makes strong bonded between steel pipe and the plastic layer, can not separate whole tubing long service life.
Fig. 1 is a plastic-steel enclosure wall tube equipment structure schematic representation of the present invention;
Fig. 2 is a plastic-steel cladding tubing manufacturing flow chart of the present invention.
Below in conjunction with Fig. 1-Fig. 2 embodiments of the invention are done detailed explanation.
1, plastics cladding; 2, heat-fusing glue layer; 3, steel pipe layer; 4, adhesive layer; 5, interior plastic pipe layer; 11, steel pipe cleaning procedure; 12, interior plastic tube outer wall inserts the steel pipe program after squeezing binder; 13, heating chamber heating schedule; 14, heating back outer wall of steel pipe is squeezed into the hot melt adhesive program; 15, outside heat-fusing glue layer, annotate system plastics cladding program; 16, finished product.
The present invention relates to plastic-steel cladding tubing, its structure as shown in Figure 1, internal layer is interior plastic pipe layer 5, interior plastic pipe layer 5 is outer to be adhesive layer 4, adhesive layer 4 is outer to be steel pipe layer 3, steel pipe layer 3 is outer to be heat-fusing glue layer 2, heat-fusing glue layer 2 is outer to be plastics cladding 1.During fabrication, get steel pipe earlier and carry out cleaning procedure 11 pretreatment such as grade, steel pipe can be welded pipe or cold rolling, cold-drawing seamless pipe or hot seamless tube etc.Other gets plastic tube as interior plastic pipe layer 5, inserts steel pipe internal program 12 after interior plastic pipe layer outer wall squeezes binder, and raw materials such as plastic tube such as polyethylene or rigid polyvinyl chloride or polypropylene are made.The tubing that interior plastic pipe layer 5 and crowded adhesive layer 4 are combined with steel pipe layer 3 drops into heating chamber and carries out heating schedule 13, the heating chamber temperature is controlled between 150 ℃-350 ℃ according to the difference of plastic material, time is in 30 minutes, when reaching the demand temperature, charge into the hot compressed air of 0.5-1MPa, make the complete strong bonded of steel pipe and plastic tube.Heating back outer wall of steel pipe is squeezed into hot melt adhesive program 14, after molten hot glue is cooled to the fritting state, annotates system plastics cladding 1 outside glue-line, and the plastic raw material of selecting for use is identical with interior plastic pipe layer, puts finished product again in order.
Claims (3)
1, a kind of plastic-steel cladding tubing is characterized in that having interior plastic pipe layer (5), the adhesive layer (4) that interior plastic pipe layer is outer, and adhesive layer is outward steel pipe layer (3), steel pipe layer heat in the exterior melten gel layer (2), heat-fusing glue layer are shaped on plastics cladding (1) outward.
2, the manufacture method of plastic-steel cladding tubing, it is characterized in that getting steel pipe cleans, other gets plastic tube, squeeze into binder (4) at the outer wall of plastic tube, insert in the steel pipe squeezing the plastic tube that binder is arranged, the tubing that the interior plastic pipe layer (5) and the steel pipe layer (3) of combination are formed drops in the heating chamber, the temperature of heating chamber is controlled at 150 ℃-350 ℃, in 30 minutes heating times, take out the back and squeeze into hot melt adhesive at outer pipe wall, make hot melt adhesive be cooled to half molten state, outside the heat-fusing glue layer (2) of fritting state, annotate system plastics claddings (1) again.
3, the manufacture method of plastic-steel cladding tubing as claimed in claim 2, the raw material that it is characterized in that interior plastic pipe layer (5) and plastics cladding (1) is polyethylene or PVC or polypropylene.
