Description
Technical field
The utility model relates to kind of an anti-corrosive steel tube, relates in particular to a kind of composite coating anti-corrosive steel tube.
Background technique
Increase along with China's oil refining industry processing high-sulphur crude quantity; What one-tenth branch such as the sulphur in the crude oil, hydrogen sulfide, sulfur monoxide produced becomes increasingly conspicuous to equipment and Corrosion of Pipeline problem; With the carbon steel be main material make like cool exchanging equipments and the pipeline that aggressive medium is arranged such as heat exchangers; There are electrochemical corrosion, high temperature corrosion and cause it to scrap too early, cause the waste of lot of materials, increase production cost of investment and unplanned loss of fixed assets and production safety hidden danger.
Pipeline corrosion protection through taking various means, is protected the metallic conduit of easy corrosion exactly, reaches the purpose that prolongs its working life, adopts usually that physics is anticorrosion, chemical preservation, electrochemical anti-corrosive or the like method.Yet present composite coating anti-corrosive steel tube antiseptic effect is unsatisfactory.
The model utility content
For solving the deficiency of existing technology, the utility model provides a kind of composite coating anti-corrosive steel tube.
The utility model is achieved through following technical proposals:
A kind of composite coating anti-corrosive steel tube comprises steel pipe, and said outer surface of steel tube is coated with epoxide powder coating layer, polyolefin adhesive coating and polyethylene coating successively.
Further, in the composite coating anti-corrosive steel tube, said epoxide powder coating layer thickness is 80～90um, and said polyolefin adhesive coating thickness is 170～250um, and said polyethylene coating thickness is 1000～2000um.
The technique effect of the utility model is following:
(1) pipeline has very high sealing, and long-time running can significantly reduce cost, the protection environment;
(2) very strong corrosion resistance, can reach 30-50 working life;
(3) under cryogenic conditions, also have good corrosion-resistant and impact resistance, the PE water absorption rate is low;
(4) it is high to possess epoxy intensity simultaneously, and the PE moisture absorption is low good etc. with the PUR ductility, and very high anticorrosion reliability is arranged;
(5) interlayer is combined, and it is effective that high temperature solidifies levelling down.
Description of drawings
Fig. 1 is the utility model composite coating anti-corrosive steel tube structure cut-away view.
Wherein, among the figure: l, steel pipe; 2, epoxide powder coating layer; 3, polyolefin adhesive coating; 4, polyethylene coating.
Embodiment
Below in conjunction with embodiment the utility model is further described.
As scheme shown in the l, a kind of composite coating anti-corrosive steel tube adopts industry conventional method to be coated with 80～90um epoxide powder coating layer 2,170～250um polyolefin adhesive coating 3 and 1000～2000um polyethylene coating 4 at steel pipe 1 outer surface successively.
The utility model structure is made up of following three-layer protection layer, and bottom is a fusion bonded epoxy, and the mesosphere is an adhesive, and surface layer is an extruded polyethylene, protective coating total thickness pact >=1.2mm.In three-decker, the main effect of clinkery epoxy powder coating is: form continuous filming, directly bond with steel tube surface, have good chemical resistance and antikathode stripping performance; Form chemical bonding with the active group reaction of mesosphere adhesive, guarantee that whole anticorrosive coat has good cohesiveencess under higher temperature.Polyolefin adhesive is adopted in the mesosphere; Can react generation hydrogen bond or chemical bond with the epoxide group of clinkery epoxy powder coating; Make mesosphere and bottom form good bonding, have good affinity interaction with surface layer simultaneously, so mesosphere and surface layer also have the advantages of good caking property ability.The main effect of polyethylene surface layer has been mechanical protection and antisepsis.
The utility model adopts three-layer protection, has the good technical effect:
(1) pipeline has very high sealing, and long-time running can significantly reduce cost, the protection environment;
(2) very strong corrosion resistance, can reach 30-50 working life;
(3) under cryogenic conditions, also have good corrosion-resistant and impact resistance, the PE water absorption rate is low;
(4) it is high to possess epoxy intensity simultaneously, and the PE moisture absorption is low good etc. with the PUR ductility, and very high anticorrosion reliability is arranged;
(5) interlayer is combined, and it is effective that high temperature solidifies levelling down.
It is to be noted; The utility model is not limited to above-mentioned mode of execution; Any simple modification, equivalent variations and modification that any professional and technical personnel of being familiar with does the foregoing description in based on the utility model technological scheme all belong in the protection domain of the utility model.
