Abstract
The utility model provides a kind of compound pipe port anti-corrosion circle of inner liner stainless steel tubing, including cylindrical body circle body, and ring groove is provided on a bottom surface of the circle body, and ring groove and the compound pipe port of inner liner stainless steel tubing are interference fitted.The utility model passes through the anti-corrosion circle covered at composite pipe port and carries out anti-corrosion to port, convenient to remove replacement at any time, easy to use.
Description
Technical field
The utility model relates to composite water pipe field, specifically a kind of compound pipe port anti-corrosion circle of inner liner stainless steel tubing.
Background technique
Liner two-phase stainless steel composite steel pipe is in steel pipe inner wall composite thin wall stainless steel tube, and this dual-metal clad steel pipe is significantly
Corrosion resistance of steel pipe during water delivery, defeated hot water, defeated coal gas, defeated natural gas, oil transportation is improved, surface is smooth, fluid resistance
The advantages of power is small, and remains steel pipe mechanical intensity height, and welding can be used, ditch mortise, be threadedly coupled, good airproof performance, overcomes plating
Zinc steel pipe is perishable, using the defect of the plastic tube of hot-melt adhesive paste easy leak and aging, be gas transmission, water delivery, oil transportation steel pipe liter
The ideal product that grade is regenerated.
Inner wall of the pipe forms one layer of very thin chromium oxide film, the film to liner two-phase stainless steel composite steel pipe in use
Metal is prevented to continue to aoxidize, therefore stainless steel has strong corrosion resistance, can not only bear the corrosion of water and air, and can be with
Bear the corrosion of weak acid and weak base.But the film of liner can only carry out anti-corrosion, in actual use, certain tubing to steel pipe inner wall
Port is directly exposed to air, and is needed to carry out additional technique and is carried out anti-corrosion to port, for example coats and apply at port
Layer prevents the port from corroding.The disadvantages of the method are as follows change the size of port after applying coating, port again with other steel pipe into
When row connection, coating is needed to strike off, it is time-consuming and laborious.
Utility model content
The utility model in order to solve problems in the prior art, it is anti-to provide a kind of compound pipe port of inner liner stainless steel tubing
Corruption circle carries out anti-corrosion to port by covering the anti-corrosion circle at composite pipe port, convenient to remove replacement at any time, easy to use.
The utility model includes cylindrical body circle body, is provided with ring groove on a bottom surface of the circle body, ring groove with
The compound pipe port interference fit of inner liner stainless steel tubing.
It is further improved, the ring groove depth is 3/4ths of circle body height, connects circle body and pipe end
It connects closer.
It being further improved, the inner wall of the ring groove is rubber layer, pipe end protected by rubber layer,
It prevents from frequently installing and removes anti-corrosion circle damage tube surfaces.
Be further improved, be provided with several antiskid particles on the circle body side, facilitate can be removed at any time when needing it is anti-
Corruption circle.
It is further improved, since anti-corrosion circle only needs to protect the port of tubing, circle body center is provided with through-hole and is made into open circles
The structure of ring can save material.
The utility model beneficial effect is: anti-corrosion is carried out to port by covering the anti-corrosion circle at composite pipe port,
It is convenient to remove replacement at any time, it is easy to use.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
The utility model includes cylindrical body circle body, is provided with ring groove on a bottom surface of the circle body, ring groove with
The compound pipe port interference fit of inner liner stainless steel tubing.
It is further improved, the ring groove depth is 3/4ths of circle body height, connects circle body and pipe end
It connects closer.
It being further improved, the inner wall of the ring groove is rubber layer, pipe end protected by rubber layer,
It prevents from frequently installing and removes anti-corrosion circle damage tube surfaces.
Be further improved, be provided with several antiskid particles on the circle body side, facilitate can be removed at any time when needing it is anti-
Corruption circle.
It is further improved, since anti-corrosion circle only needs to protect the port of tubing, circle body center is provided with through-hole and is made into open circles
The structure of ring can save material.
There are many utility model concrete application approach, and the above is only the preferred embodiment of the utility model, should
It points out, for those skilled in the art, without departing from the principle of this utility model, can also make
Several improvement out, these improvement also should be regarded as the protection scope of the utility model.
