Description

A kind of plastic-coated steel with adpting flange
Technical field
This utility model relates to plastic-coated steel technical field, particularly relates to a kind of plastic-coated steel with adpting flange.
Background technology
Plastic-coated steel is that employing PE (modified poly ethylene) carries out hot-dip plastic or EP (epoxy resin) carries out the inside and outside product coated Product, have excellent decay resistance.Coating itself also has good electric insulating quality simultaneously, will not produce galvanic corrosion, water suction Rate is low, and mechanical strength is high, and coefficient of friction is little, it is possible to reach the purpose of life-time service, moreover it is possible to effectively prevent root system of plant and soil The destruction etc. of earth environmental stress, its have in use techniques below have a little 1 adapt to buried and wet environment, it is possible to high temperature resistant and Extremely low temperature;2 capacity of resisting disturbance are strong, if plastic-coated steel is as cable sleeve, can effectively shield the signal disturbing in the external world; 3 to bear the intensity of pressure good, and maximum pressure is up to 6Mpa;4 good insulation preformances, the protection pipe as electric wire leaks electricity never Phenomenon;5 impulse-free robustness, tube wall are smooth, are suitable for the when of construction wearing electric wire or cable.
Due to the serviceability that above-mentioned plastic-coated steel is superior, preferentially select plastic-coated when being used for carrying chemical flowing material Steel pipe, it is contemplated that during long distance delivery liquid, pipeline to be affected by various factors such as the erosions of chemical substance, therefore When laying pipeline, the connected mode between each pipe fitting becomes as main problem.
The connected mode of existing laying subterranean pipe line mainly has three kinds: one is to use ring flange to connect;Its two be use Bayonet joint;Its three be use welding, due to traditional welding method, high-temperature heating makes to be attached to the plastic-coated of steel tube surface Melting layer damages, and makes to be corroded more susceptible to extensive chemical liquid around solder joint, and some plastic-coated steels are lined in pipe, although can Being welded between pipe by liner, but the liner wall thickness owing to using is relatively thin, therefore the stress deformation after welding is relatively big, Surface is easy to crack, therefore cannot use the most for a long time, departs from it addition, bayonet joint easily causes bell and spigot when being given a shock, And then cause fluid to leak, so the pipeline that conveying chemical liquid is laid is suitable only for Flange joint.
But traditional Flange joint be only merely between ring flange face patch and, this kind of laminating type is relatively simple, but Also easily cause the sealing ring between liquid leakage or corrosion pipeline, cause unnecessary loss, even can have a strong impact on use In the life-span, need personnel to make regular check on, expend a large amount of manpower and material resources.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one proposed is with connection method Blue plastic-coated steel.
To achieve these goals, this utility model adopts the technical scheme that
A kind of plastic-coated steel with adpting flange, it is characterised in that: include body, be provided with outside body external coating, Inner side is provided with undercoating, is provided with anode flange in the side of body, opposite side is provided with cathode flange, and the end face at anode flange sets The tenon put, the end face at cathode flange is provided with boss, is provided with tongue-and-groove on boss.
Preferably, described anode flange is provided with one group of first connecting hole, described cathode flange is provided with one group Two connecting holes.
Preferably, the outside at described cathode flange is additionally provided with external seal pad.
Preferably, in described tongue-and-groove, it is additionally provided with inner seal ring.
Preferably, described tenon is annular plate-like structure.
Preferably, described tongue-and-groove is annular groove.
The utility model has the advantage of: this utility model adds with labyrinth structure on the basis of original plastic-coated steel Adpting flange, install and use rear liquid and be difficult to leakage, it is to avoid chemicals attack sealing ring, improve pipe fitting service life, subtract In few personnel inspection cycle, effectively reduce and safeguard cost of use, it is adaptable to lay on a large scale.
Accompanying drawing explanation
Fig. 1 is basic structure schematic diagram of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of plastic-coated steel with adpting flange that this utility model provides, including body 1, described pipe Body 1 is hollow cylinder steel pipe, in its surface brushing external coating 2, soaks figure undercoating 3 on the inwall of described body 1, for ensureing Antiseptic property, described external coating 2, undercoating 3 use the preferable epoxide powder coating of antiseptic property to make.
Be provided with anode flange 4 in the side of described body 1, opposite side is provided with cathode flange 5, during described anode flange 4 is Its central band has the cylindrical sheet of through hole, and its outer face is fixing connects tenon 4.1, and tenon 4.1 is annular plate-like structure, its annular center With anode flange 4 coaxial line.
Described cathode flange 5 is similarly the center cylindrical sheet structure with through hole, in its outer face around cathode flange 5 Center is fixing connects boss 5.1, and the end face at described boss 5.1 is provided with tongue-and-groove 5.2, and tongue-and-groove 5.2 is annular groove.One steel pipe Tongue-and-groove 5.2 and tenon 4.1 corresponding matching of another steel pipe, in tongue-and-groove 5.2, paste inner seal ring 8, beyond boss 5.1 Cathode flange 5 end face on also paste external seal pad 7, described inner seal ring 8 uses plastic material to make with external seal pad 7, So benefit of design is that the tongue-and-groove 5.2 between pipe fitting with pipe fitting coordinates when laying with tenon 4.1, described inner seal ring 8 and External seal pad 7 is squeezed power effect, and making can better seal between pipe fitting and pipe fitting.
Described anode flange 4 is provided with six the first connecting holes 6.1, described cathode flange 5 is provided with six second Connecting hole 6.2.When connecting between pipe fitting, described first connecting hole 6.1 and the second connecting hole 6.2 are by the bolt cooperated Fix with nut and be connected.
