Description

A kind of improved steel-plastic composite pressure pipe
Technical field
The utility model relates to a kind of pipe structure, specially a kind of improved steel-plastic composite pressure pipe.
Background technique
Steel-plastics composite pipe, product is using seamless steel pipe, welded still pipe as base tube, interior finishing high adhesion force, anti-corrosion, food-grade The polyethylene powder coating or epoxy coating of hygiene-type.Using pre-treatment, preheating, interior coating, levelling, aftertreatment technology system At the zinc-plated internal plastic coating composite steel tube of water supply, be the upgraded product of traditional galvanized pipe, steel-plastics composite pipe is generally threadedly coupled.
Existing steelplastic pipe body structure, by being combined in steel pipe internal layer and outer layer equipped with plastic layer, such tube body When in use, unbearable biggish internal pressure, and corrosion resistance is not strong.
Utility model content
The purpose of this utility model is to provide a kind of improved steel-plastic composite pressure pipes, to solve in above-mentioned background technique The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions: a kind of improved steel-plastic composite pressure pipe, packet Erosion resistant coating, outer plastic layer, outer adhesive layer, steel pipe fitting, interior adhesive layer, inner plastic layer, elastic cushion, interior raised line and strip groove are included, it is described The outer layer of steel pipe fitting is successively arranged outer adhesive layer and outer plastic layer, and the outer surface of the outer plastic layer is coated with erosion resistant coating, the steel pipe fitting Inner surface be equipped with the fixed interior raised line of multiple annular arrays, the strip groove phase that each interior raised line is equipped with inner plastic layer outer surface It fastens and fixes, and be equipped with interior adhesive layer between inner plastic layer and steel pipe fitting.
Further, the erosion resistant coating is polyethylene anticorrosive coating.
Further, the outer plastic layer and inner plastic layer are polythene material layer or heat resistant polyethylene material layer.
Further, the outer adhesive layer and interior adhesive layer are hot melt adhesive layer.
Further, the interior raised line top surface of each steel pipe fitting is equipped with elastic cushion, and the elastic cushion is rubber pad, and band The interior raised line of flexible pad is buckled in corresponding strip groove.
Compared with prior art, the utility model has the beneficial effects that this kind of improved steel-plastic composite pressure pipe, surface is set There is erosion resistant coating greatly increased tube body service life, and is set to the interior raised line and item mutually fastened between steel pipe fitting and inner plastic layer Shape slot significantly increases the bonding firmness between steel pipe fitting and inner plastic layer, while being equipped on the surface of interior raised line for interior The elastic cushion for moulding layer buffering, reduces the anti-internal pressure capability of inner plastic layer by the buffer function of elastic cushion.
Detailed description of the invention
Fig. 1 is the utility model of the whole structure diagram;
In figure: 1, erosion resistant coating, 2, outer plastic layer, 3, outer adhesive layer, 4, steel pipe fitting, 5, interior adhesive layer, 6, inner plastic layer, 7, bullet Property pad, 41, interior raised line, 61, strip groove.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of improved steel-plastic composite pressure pipe, including it is anti- Rotten layer 1, outer plastic layer 2, outer adhesive layer 3, steel pipe fitting 4, interior adhesive layer 5, inner plastic layer 6, elastic cushion 7, interior raised line 41 and strip groove 61, the outer layer of the steel pipe fitting 4 is successively arranged outer adhesive layer 3 and outer plastic layer 2, and the outer surface of the outer plastic layer 2 is coated with erosion resistant coating 1, the inner surface of the steel pipe fitting 4 is equipped with the fixed interior raised line 41 of multiple annular arrays, each interior raised line 41 with outside inner plastic layer 6 The strip groove 61 that surface is equipped with is engaged merging and fixes, and interior adhesive layer 5 is equipped between inner plastic layer 6 and steel pipe fitting 4.Described is anti- Rotten layer 1 is polyethylene anticorrosive coating.The outer plastic layer 2 and inner plastic layer 6 is polythene material layer or heat resistant polyethylene material layer. The outer adhesive layer 3 and interior adhesive layer 5 is hot melt adhesive layer.41 top surface of interior raised line of each steel pipe fitting 4 is equipped with elastic cushion 7, the elastic cushion 7 is rubber pad, and the interior raised line 41 with elastic cushion 7 is buckled in corresponding strip groove 61, passes through elastic cushion 7 Effect, very big buffer function is played to inner plastic layer 6, inner plastic layer 6 is made to be able to bear bigger surge.
This kind of improved steel-plastic composite pressure pipe, surface are equipped with erosion resistant coating greatly increased tube body service life, and steel It is set to the interior raised line mutually fastened and strip groove between pipe fitting and inner plastic layer, significantly increases between steel pipe fitting and inner plastic layer Firmness is bonded, while being equipped with the elastic cushion for inner plastic layer buffering on the surface of interior raised line, passes through the buffer function of elastic cushion Reduce the anti-internal pressure capability of inner plastic layer.
