Description

A kind of COLD DRAWN PRECISION STEEL TUBE FOR
Technical field
The utility model relates to steel pipe field, particularly relates to a kind of COLD DRAWN PRECISION STEEL TUBE FOR.
Background technique
Architecture storey is high-rise, after every layer of building completes, the roof of every floor will be carried out floor and be bound, need with concrete, top layer base plate to be polished, the transmission of concrete slurry generally adopts large-scale pipeline, floor top is risen to by power pull, in draw process, because material comprises cement, the hard materials such as sand, in transmitting procedure and easily, wearing and tearing are caused to pipeline, conventional pipelines is mostly crust COLD DRAWN PRECISION STEEL TUBE FOR, endothelium is made up of anti-wear material, working life seldom, frequent periodic replacement internal layer, the utility model have employed a kind of new COLD DRAWN PRECISION STEEL TUBE FOR, with solving the not wear-resistant problem of steel pipe inner wall.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of COLD DRAWN PRECISION STEEL TUBE FOR, can have good wear-resisting property, can resist long-time mechanical wear, improve stock utilization, extends the working life of COLD DRAWN PRECISION STEEL TUBE FOR.
Described COLD DRAWN PRECISION STEEL TUBE FOR comprises three-decker, and outermost surface supports outer tube, and described outer tube is hexangle type steel pipe, for supporting whole COLD DRAWN PRECISION STEEL TUBE FOR, plays safety protection effect.
A kind of optimal technical scheme, described skin supports outer tube and adopts 304 stainless steel materials.
A kind of optimal technical scheme, in order to prevent steel pipe to be corroded, supporting on outer tube outer wall at skin and being coated with polyethylene anticorrosive coating or epoxy coating layer.
Innermost layer is conveyance conduit, and described innermost layer is inwall alloy pipe, is made up of alloy steel pipe, and described interior pipe is alloy ERW, and pipe wear is even, and avoid concentrated wear, described internal layer conveyance conduit body thickness is 5-8 millimeter.
Be packed layer between outer tube and interior pipe, described packed layer is made up of the plastic material of densification, plays the buffer function of outer tube and interior pipe, and packed layer is in order to better play damping effect simultaneously, and packed layer is provided with circular groove.
Meanwhile, at described COLD DRAWN PRECISION STEEL TUBE FOR two ends, head is provided with foam damping ring, is convenient to the connection of two steel pipes, in foam damping ring, be provided with link bolt hole, is convenient to adopt bolt that two steel pipe mechanicals are connected, thus increases the length of steel pipe.Foam has good shock-absorbing function, avoids the compressing of joint because of the external world of two steel pipes, clashes into, and produces loosening, affects the stable of entirety.
The beneficial effects of the utility model are: a kind of COLD DRAWN PRECISION STEEL TUBE FOR dimensional accuracy of the utility model is high, inner and outer surface roughness is good, and steel pipe can bear high pressure, No leakage, high-accuracy, high finishingness and joint clod wash is indeformable, two fastener for connection are firm simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of COLD DRAWN PRECISION STEEL TUBE FOR structural representation of the utility model;
In accompanying drawing, the mark of each parts is as follows:
1 is inwall alloy pipe, and 2 is hexangle type steel pipe support body, 3 link bolt hole, and 4 is packed layer, and 5 is circular groove, and 6 is foam damping ring.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of COLD DRAWN PRECISION STEEL TUBE FOR, comprises three-decker, and outermost surface supports outer tube, and described outer tube is hexangle type steel pipe, for supporting whole COLD DRAWN PRECISION STEEL TUBE FOR, plays safety protection effect, and described skin supports outer tube and adopts 304 stainless steel materials.
Innermost layer is conveyance conduit, and described innermost layer is inwall alloy pipe, is made up of alloy steel pipe, and described interior pipe is alloy ERW, and pipe wear is even, and avoid concentrated wear, described internal layer conveyance conduit body thickness is 5-8 millimeter.
Be packed layer between outer tube and interior pipe, described packed layer is made up of the plastic material of densification, plays the buffer function of outer tube and interior pipe, and packed layer is in order to better play damping effect simultaneously, and packed layer is provided with circular groove.
Meanwhile, at described COLD DRAWN PRECISION STEEL TUBE FOR two ends, head is provided with foam damping ring, is convenient to the connection of two steel pipes, in foam damping ring, be provided with link bolt hole, is convenient to adopt bolt that two steel pipe mechanicals are connected, thus increases the length of steel pipe.Foam has good shock-absorbing function, avoids the compressing of joint because of the external world of two steel pipes, clashes into, and produces loosening, affects the stable of entirety.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
