Abstract

The utility model provides an inner and outer coating plastic compound steel pipe with thick-walled stainless steel joints. The inner and outer coating plastic compound steel pipe with the thick-walled stainless steel joints comprises a base pipe layer, an inner anticorrosive coating, an outer anticorrosive coating and two thick-walled stainless steel joints. The base pipe layer is a steel pipeline. The inner anticorrosive coating and the outer anticorrosive coating are respectively arranged on the inner surface and the outer surface of the base pipe layer. The two thick-walled stainless steel joints are respectively connected at both ends of the base pipe layer. Not only can the inner and outer coating plastic compound steel pipe with the thick-walled stainless steel joints ensure inner and outer anticorrosive performance of a pipe body, but also anticorrosion repaired opening treatment inside and outside a welding joint is not needed after site installation and welding due to good anticorrosive performance of the thick-walled stainless steel joints, so the construction technology is simple and construction cost is low. In addition, due to the fact that a traditional welding mode for connecting between the compound steel pipes can be adopted, original connecting technology is not changed.

Description

A kind of inside and outside plastic coated composite steel pipe with the heavy wall stainless joint
Technical field
The utility model relates to a kind of inside and outside plastic coated composite steel pipe, particularly relates to a kind of inside and outside plastic coated composite steel pipe with the heavy wall stainless joint.
Background technique
Inside and outside plastic coated composite steel pipe is a kind of internal and external anti-corrosive multiple tube relatively more commonly used at present, its main technique is at the preserving timber bed of material of steel pipe inner and outer surface by materials such as epoxy resin, polyethylene of different process coating one deck, to reach the requirement of steel pipe internal and external anti-corrosive.Although the internal and external anti-corrosive problem of this inside and outside plastic coated composite steel pipe itself all is resolved, but in pipeline field construction and installation process, mostly still adopt the steel pipe welding connecting mode, because the antiseptic property of steel pipe is poor, therefore need also after welding is finished that welding junction is done the internal and external anti-corrosive repaired mouth and process, so that the internal and external anti-corrosive of welding junction and body keep continuity and conformity.When actual field operates, the outer anticorrosion manual type that can adopt of welding junction is carried out, but interior anticorrosion sizable difficulty that but has, sometimes even at all can't finish the anticorrosion of welding junction inside, will affect the anticorrosion of whole pipeline like this, the result has shortened the working life of whole system greatly.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of need not that welding junction is carried out the inside and outside plastic coated composite steel pipe with the heavy wall stainless joint that internal and external anti-corrosive is processed.
In order to achieve the above object, the inside and outside plastic coated composite steel pipe with the heavy wall stainless joint that provides of the utility model comprises parent tube layer, inner anticorrosioning coating, outer anti-corrosive coating and two heavy wall stainless joints; Wherein the parent tube layer is steel pipe; Inner anticorrosioning coating and outer anti-corrosive coating are separately positioned on the inner and outer surface of parent tube layer; Two heavy wall stainless joints are connected to the two ends of parent tube layer.
Described heavy wall stainless joint has identical diameter and thickness with the parent tube layer.
The length of described heavy wall stainless joint is 50mm-500mm, can adopt seamless or the vertical masonry joint stainless-steel pipe.
The inside and outside plastic coated composite steel pipe with the heavy wall stainless joint that the utility model provides not only can guarantee that pipeline body has the internal and external anti-corrosive performance, simultaneously because the antiseptic property of heavy wall stainless joint itself is good, therefore need not after Site Welding is installed to process carrying out again corrosion-resistanting interpolating port inside and outside the welding junction, so construction process is simple, construction cost is low.In addition, because the connection between composite steel tube still can be taked traditional welding manner, therefore can not change original connection technique.
Description of drawings
The inside and outside plastic coated composite steel pipe longitudinal construction sectional view with the heavy wall stainless joint that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the inside and outside plastic coated composite steel pipe with the heavy wall stainless joint that the utility model provides is elaborated.
As shown in Figure 1, the inside and outside plastic coated composite steel pipe with the heavy wall stainless joint that provides of the utility model comprises parent tube layer 1, inner anticorrosioning coating 2, outer anti-corrosive coating 3 and two heavy wall stainless joints 4; Wherein parent tube layer 1 is steel pipe; Inner anticorrosioning coating 2 and outer anti-corrosive coating 3 are separately positioned on the inner and outer surface of parent tube layer 1; Two heavy wall stainless joints 3 are connected to the two ends of parent tube layer 1.
Described heavy wall stainless joint 3 has identical diameter and thickness with parent tube layer 1.
The length of described heavy wall stainless joint 3 is 50mm-500mm, can adopt seamless or the vertical masonry joint stainless-steel pipe.
When needs produce that the utility model provides with the inside and outside plastic coated composite steel pipe of heavy wall stainless joint the time, at first weld respectively a heavy wall stainless joint 3 at the two ends of parent tube layer 1, then will adopt tratitional technology make inner anticorrosioning coating 2 and outer anti-corrosive coating 3 with parent tube layer 1 inner and outer surface of heavy wall stainless joint 3, and directly corresponding two heavy wall stainless joints 3 on adjacent two inside and outside plastic coated composite steel pipes be welded together when pipeline field is installed and get final product.
