Abstract
The utility model proposes a kind of steel pipe fitting with polyurea anti-corrosion coating, comprising: steel pipe fitting body and the anticorrosive coat being positioned at described steel pipe fitting body outer surface; Described anticorrosive coat is the anticorrosive coat that carbamide paint is made.Described anticorrosive coat is by the outer surface adhering junction of spraying method and described steel pipe fitting body.The beneficial effects of the utility model are as follows: by adopting at steel outer surface of pipe fittings spray polyurea coating as anticorrosive coat, effectively can overcoming steel pipe fitting loses an antiseptic effect difficult problem because using for a long time, there is good weatherability simultaneously, UV resistant light is high, cohesive force is high, antiseptic property is good, mechanical property advantages of higher.This cladding technique, with the physical property of its excellence, good resistance to chemical corrosion and Creating Green pipeline environment advantage, obtains and applies comparatively widely in China's pipeline corrosion protection engineering.
Description
Technical field
The utility model relates to oil, natural gas transport steel pipe fitting technical field, refers to a kind of steel pipe fitting with polyurea anti-corrosion coating especially.
Background technique
In order to improve the antiseptic property of steel outer surface of pipe fittings, often need its coating anticorrosive coat, at present, most brushing corrosion resistant coating such as the anticorrosive coat for the steel pipe fitting of transfer oil, rock gas etc., FBE, or 3PE anticorrosive coat etc.Brushing corrosion resistant coating can only carry out of short duration protection to steel pipe fitting as the mode of anticorrosive coat; Although brushing epoxy powder or 3PE anticorrosive coat mode can play antiseptic effect more of a specified duration, this anticorrosive coat surface hardness is very easily damaged, and need carry out secondary repairing, cause the conformity of anticorrosive coat, forms weak spot.Finally cause steel pipe fitting short for working life.
Model utility content
The utility model proposes a kind of steel pipe fitting with polyurea anti-corrosion coating, solve the problem that weak effect, working life are short repeatedly of steel pipe fitting anticorrosive coat in prior art.
The technical solution of the utility model is achieved in that
There is a steel pipe fitting for polyurea anti-corrosion coating, comprising: steel pipe fitting body and the anticorrosive coat being positioned at described steel pipe fitting body outer surface; Described anticorrosive coat is the anticorrosive coat that carbamide paint is made.
Described anticorrosive coat is by the outer surface adhering junction of spraying method and described steel pipe fitting body.
The diameter of described steel pipe fitting body is 22 ~ 1020 millimeters.
The thickness of described anticorrosive coat is 300 ~ 800 microns.
Described steel pipe fitting body is the steel pipe fitting body of outer surface after sandblasting or impeller blasting.
Implementation procedure of the present utility model and principle as follows:
First the processing of rust removing such as sandblasting or ball blast is carried out to the outer surface of steel pipe fitting body, then spray polyurea coating, the outer surface of whole steel pipe fitting body is covered by fully melting flowing levelling, and there is no space between base material, form chemical chain in a way, the curing agent having added cross-linking reaction forms insoluble not molten scleroid coating after heating.
Polyurea materials has quick solidifying, continuous spray constructs the feature of not trickling.
Above-mentioned outdoor steel pipe fitting comprises the steel pipe fittings such as elbow, threeway, reducing.
The beneficial effects of the utility model are:
By adopting at steel outer surface of pipe fittings spray polyurea coating as anticorrosive coat, effectively can overcoming steel pipe fitting loses an antiseptic effect difficult problem because using for a long time, there is good weatherability simultaneously, UV resistant light is high, cohesive force is high, antiseptic property is good, mechanical property advantages of higher.This cladding technique, with the physical property of its excellence, good resistance to chemical corrosion and Creating Green pipeline environment advantage, obtains and applies comparatively widely in China's pipeline corrosion protection engineering.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the axial arrangement sectional view with the steel pipe fitting of polyurea anti-corrosion coating described in the utility model;
In figure:
1, steel pipe fitting body, 2, anticorrosive coat.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment is as shown in Figure 1 known, and a kind of steel pipe fitting with polyurea anti-corrosion coating described in the utility model, comprising: steel pipe fitting body 1 and the anticorrosive coat 2 being positioned at steel pipe fitting body 1 outer surface; The anticorrosive coat that anticorrosive coat 2 is made for carbamide paint.
Described anticorrosive coat 2 is by the outer surface adhering junction of spraying method and steel pipe fitting body 1.
The diameter of described steel pipe fitting body 1 is 22 ~ 1020 millimeters.
The thickness of described anticorrosive coat 2 is 300 ~ 800 microns.
Described steel pipe fitting body 1 is the steel pipe fitting body of outer surface after sandblasting or impeller blasting.
Above-mentioned there is the steel pipe fitting of polyurea anti-corrosion coating implementation procedure and principle as follows:
First the processing of rust removing such as sandblasting or ball blast is carried out to the outer surface of steel pipe fitting body 1, then spray polyurea coating, the outer surface of whole steel pipe fitting body 1 is covered by fully melting flowing levelling, and there is no space between base material, form chemical chain in a way, the curing agent having added cross-linking reaction forms insoluble not molten scleroid coating after heating.
Due to polyurea materials there is quick solidifying, continuous spray constructs the feature of not trickling.By adopting at steel outer surface of pipe fittings spray polyurea coating as anticorrosive coat, effectively can overcoming steel pipe fitting loses an antiseptic effect difficult problem because using for a long time, there is good weatherability simultaneously, UV resistant light is high, cohesive force is high, antiseptic property is good, mechanical property advantages of higher.
Cladding technique described in the utility model, with the physical property of its excellence, good resistance to chemical corrosion and Creating Green pipeline environment advantage, obtains and applies comparatively widely in China's pipeline corrosion protection engineering.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
