Abstract
The utility model discloses epoxy coating flame-retardant and anti-static composite steel tube in a kind of outer fluorine carbon, it is characterized in that: become by epoxy coating, carbon steel layer, fluororine-carbon coating, stainless steel lining head group, wherein, epoxy coating is positioned at carbon steel layer internal surface, fluororine-carbon coating is positioned at carbon steel layer outer surface, and stainless steel interfacing is positioned at carbon steel layer inwall two ends.
Description
Technical field
The utility model relates to composite steel tube, particularly epoxy coating flame-retardant and anti-static composite steel tube in the outer fluorine carbon of one.
Background technique
At present, the steel-plastic composite pipe that market uses, be mainly the hot clinkery epoxy powder of steel pipe inside and outside wall or polyethylene coating, it has good corrosion resistance, solves the problem of the easy corrosion of steel pipe.But these two kinds of steel-plastic composite pipes also have many shortcomings as: weatherability is poor, and Ultraviolet radiation is easily aging.
Metal fluorocarbon coating due to the fluorine element electronegativity introduced large, carbon-fluorine bond can be strong, have properties superior especially: weatherability, heat resistance (180 DEG C-380 DEG C), lower temperature resistance (-200 DEG C), chemical resistance.Fire-retardant and anti-static agent is added when applying, fire-retardant also very outstanding with anti-static electricity property.
On the basis of inner and outer wall of steel tube process; inner surface heat clinkering epoxy powder; outer wall electrostatic spraying metal fluorocarbon coating; form the fluorine carbon protective layer of one deck densification; thus solve the shortcoming of steel-plastic composite pipe weatherability difference; possess good chemical resistance, protection steel pipe is not by corrosion simultaneously.
Model utility content
For solving the shortcoming of plain carbon steel plastic composite weatherability difference, the utility model object is to provide one and has excellent weather resistance, chemical resistance, and epoxy coating flame-retardant and anti-static composite steel tube in the outer fluorine carbon of fire-retardant and anti-static agent.
The purpose of this utility model adopts following technological scheme to realize:
Epoxy coating flame-retardant and anti-static composite steel tube in a kind of outer fluorine carbon, is characterized in that: be made up of epoxy coating 1, carbon steel layer 2, fluororine-carbon coating 3, stainless steel interfacing 4.Wherein, epoxy coating 1 is positioned at carbon steel layer 2 internal surface, and fluororine-carbon coating 3 is positioned at carbon steel layer 2 outer surface, described stainless steel interfacing 4, for being welded on the stainless steel ring steel belt of carbon steel layer 2 two ends inwall, preventing steel pipe from destroying inwall fluororine-carbon coating when welding, causing carrying out repaired mouth.
The utility model has excellent fire-retardant, antistatic, corrosion protection, mechanical property, non-scaling, fluid resistance are little, environmental protection sanitary, meet sanitary standard for drinking water, can not non-dust absorption and non-fouling, soil resistance is good, overlength weatherability, is adapted at coal, petroleum gas, chemical industry, construction industry, municipal engineering vigorously promotes the use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
In figure: 1-epoxy coating; 2-carbon steel layer; 3-fluororine-carbon coating; 4-stainless steel interfacing.
Embodiment
Below by way of accompanying drawing, the utility model is further illustrated
As shown in Figure 1: epoxy coating flame-retardant and anti-static composite steel tube in outer fluorine carbon, weld one section of ring stainless steel band at its two ends inwall on the basis of steel pipe impeller blasting, for stainless steel interfacing 4, then the hot clinkery epoxy powder of special device is used, solidify to form epoxy coating 1, finally use high pressure electrostatic painting equipment, at outer wall of steel pipe metalizing F-C paint, wait for and solidify to form fluororine-carbon coating 3.
The above; be only the utility model preferably embodiment; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses, the simple change of the technological scheme that can obtain apparently or equivalent substitution all fall in protection domain of the present utility model.
