Abstract
The invention relates to a reinforced framework steel plastic composite pipe, consisting of an internal layer plastic and an external layer plastic coating a middle layer steel pipe; the surface of the steel pipe is provided with perforations; the surface of the steel pipe is also provided with concave points arranged in the perforations. The structural performance of the steel pipe can be changed by the concave points which have the function of reinforcing ribs, thus greatly reinforcing and improving the flexural resistance, strength and rigidity of the steel pipe; meanwhile, the internal layer plastic and the external layer plastic and the steel pipe are firmly and hermetically bonded together by the perforations of the steel pipe, thus effectively avoiding the separation and dropping between the steel pipe and the plastic caused by the stress action. Therefore, the invention has the advantages of high strength, good rigidity, light weight, impact resistance, corrosion resistance, small pressure loss, firm sealing and combination between the steel and the plastic, low cost, flame resistance, good heat preservation, effectively weakening the liquid impacting noise, etc., thus being valuable for being generalized and applied.
Description
Technical field: the present invention relates to a kind of composite metal-plastic pipe, particularly a kind of steel-plastic composite pipe.
Background technique: current because various composite pipes have good usability and characteristics such as quick and easy for installation, be widely used in worker, agricultural and live in as conveyance conduit, like aluminium-plastic composite pipe, steel-plastic composite pipe and other composite metal-plastic pipe etc.And steel-plastic composite pipe is because advantage such as its intensity height, good rigidly, corrosion-resistant, the pressure loss is little, shock resistance and very popular is particularly suitable for doing bigbore pipe use.But it is certain not enough that steel-plastic composite pipe structurally also exists: (1) steel mesh framework composite tube and steel-wire carcass composite pipe intensity are on the low side, rigidity is not fine, and the application area of steel-plastic composite pipe is restricted; (2) hole pattern steel band framework steel plastic compound tube is owing to have the hole that drills through in a large number on the steel pipe, and its intensity and rigidity also reduce greatly, must remedy this loss through increasing thickness of steel pipe, causes pipe heavily to increase, and cost increases.
Summary of the invention: the objective of the invention is to overcome above-mentioned shortcoming and a kind of enhanced type framework steel plastic compound tube that can strengthen its intensity and rigidity is provided.
The object of the invention can be realized as follows: this enhanced type framework steel plastic compound tube, and mainly coat the middle level steel pipe and constitute by inner plastic and outer layer plastic, there is perforation on the surface of middle level steel pipe, and the surface of said middle level steel pipe also is provided with concave point between said perforation.
As further improvement of the present invention: the concave point of this enhanced type framework steel plastic compound tube and adjacent perforation equidistance.
As further improvement of the present invention: the middle level steel pipe internal-surface of this enhanced type framework steel plastic compound tube and outer surface all have one deck zinc-plated.
As further improvement of the present invention: have one deck PUR bonding between the internal surface of the middle level steel pipe of this enhanced type framework steel plastic compound tube and the inner plastic and between the outer surface of middle level steel pipe and the outer layer plastic.
The present invention is through adding concave point on the hole pattern shape steel pipe of tape punching; Concave point has changed the structural behaviour of steel pipe, makes it be wrinkle shape, has the effect of stiffening rib; Thereby flex resistance, intensity, rigidity of making steel pipe etc. are strengthened greatly and are improved, and particularly the external pressure strength is strengthened greatly.Simultaneously, utilize the perforation of steel pipe that steel pipe and the plastic seal of inside and outside layer are combined securely, avoid effectively that stress causes separating between steel pipe and the plastics, the situation of slippage takes place.Therefore; Steel-plastic composite pipe of the present invention have intensity height, good rigidly, in light weight, shock resistance, corrosion-resistant, the pressure loss is little, steel moulds that combination seal is firm, cost is low; Good fire resistance and heat insulating ability are arranged and effectively weaken advantages such as hydraulic shock noise, therefore, be worthy of popularization very much.
Description of drawings:
Fig. 1 is the structural representation of enhanced type framework steel plastic compound tube of the present invention;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the B-B sectional drawing of Fig. 1.
Embodiment: the present invention is made further detailed description below in conjunction with accompanying drawing:
With reference to figure 1, Fig. 2 and Fig. 3; Enhanced type framework steel plastic compound tube of the present invention as shown in Figure 1 is made up of inner plastic 1 and outer layer plastic 2 coating middle level steel pipes 3; The surface distributed of this middle level steel pipe 3 has perforation 4, and the surface of middle level steel pipe 3 also is distributed with concave point 5 simultaneously, and concave point 5 is between perforation 4.Concave point 5 preferably be distributed in adjacent perforated 4 equidistant positions on, make the structural behaviour of middle level steel pipe 3 reach best.Perforation 4 is the hole of passing middle level steel pipe 3, and is as shown in Figure 2, and preferably (mutual spacing is even) is distributed on the surface of middle level steel pipe 3 (certainly, also can be with interval but be distributed in unevenly on the surface of middle level steel pipe 3) with interval equably.Concave point 5 can form through methods such as punching press or extruding, and is as shown in Figure 3, and the one side of its steel pipe 3 in the middle level is dented another side and then is protruding next, and vice versa.The size of the size of concave point 5 and depth visual middle level steel pipe 3 and thickness and decide.
Know from above-mentioned; The inner plastic 1 of enhanced type framework steel plastic compound tube of the present invention is that plastics get into outside middle level steel pipe 3 in it and form; The bonding that is interweaved between inner plastic 1, outer layer plastic 2 and the middle level steel pipe 3 is interlocked, and very sealing combines securely.
In order to strengthen the anticorrosive property of middle level steel pipe 3, the internal surface of middle level steel pipe 3 and outer surface also have one deck zinc-plated.Simultaneously, more firm in order to strengthen combining between middle level steel pipe 3 and the inside and outside layer plastics, make the steel-plastic composite pipe performance more excellent, reaching between the internal surface of middle level steel pipe 3 and the inner plastic 1 between outer surface and the outer layer plastic 2 of middle level steel pipe 3 has one deck PUR bonding.
In sum; Steel-plastic composite pipe of the present invention utilizes the concave point 5 that adds on the middle level steel pipe 3 to form reinforced skeletal structure; Make this composite pipe have intensity height, good rigidly, in light weight, shock resistance, corrosion-resistant, the pressure loss is little, steel moulds that combination seal is firm, cost is low, good fire resistance and heat insulating ability are arranged and effectively weaken characteristics such as hydraulic shock noise.
