Abstract
A kind of outer 3PE liner aluminium flame-retardant and anti-static composite steel tube.It is characterized in that: pipeline by serving as a contrast aluminium lamination, carbon steel layer, epoxy powder layer, adhesive layer, polyethylene layer form; Use metal-to-metal adhesive between lining aluminium lamination described in it and carbon steel layer, polyethylene layer all adds fire retardant and Conductive carbon powder, reinforced pipe pipeline outer wall flame-retardant and anti-static performance.
Description
Technical field
The utility model relates to a kind of flame-retardant and anti-static composite steel tube, particularly the outer 3PE liner aluminium flame-retardant and anti-static composite steel tube of one.
Background technique
At present, 3PE anti-corrosion pipeline uses extensively in oil, Gas Industry, and it is as the anticorrosive coat of delivering pipe, weatherability, corrosion resistance, good mechanical performance.But it, also have a lot of shortcoming, as its anticorrosive coat is only limitted to outer wall of steel pipe, inwall does not do preservative treatment, easy corrosion, affects pipeline working life; Moreover existing 3PE anti-corrosive steel tube outer wall anticorrosive coat does not do flame-retardant and anti-static process, cannot use in gas discharge in mine field.
Existing a kind of bimetal complex technique, is a kind of thin wall metal pipeline brute force is fitted to thick-wall seamless or inner wall of welded pipe as anti-corrosion layer, forms a kind of composite bimetal pipe.It preserves the advantage of two kinds of different materials inherences, the complementary deficiency of they inherences, and continued to use the ripe mounting type of steel pipe tradition and technique, therefore in use convenient, reliable, health, safety.
Now by the 3PE outer wall of steel pipe aseptic technic of function admirable and the perfect adaptation of bimetal complex technique, doing on surface-treated basis at steel pipe inside and outside wall adopts metal-to-metal adhesive and mechanical force to be fitted together to one deck thin-wall aluminium pipe at inwall, then outer wall does 3PE preservative treatment, forms a kind of NEW TYPE OF COMPOSITE steel pipe.
Model utility content
In order to overcome the not anticorrosion easy corrosion of existing 3PE anti-corrosive steel tube inwall, outer wall anticorrosive coat does not possess the shortcoming of flame-retardant and anti-static process, now provides a kind of outer 3PE liner aluminium flame-retardant and anti-static composite steel tube.
Its technological scheme is as follows:
A kind of outer 3PE liner aluminium flame-retardant and anti-static composite steel tube.It is characterized in that: pipeline by serving as a contrast aluminium lamination 1, carbon steel layer 2, epoxy powder layer 3, adhesive layer 4, polyethylene layer 5 form; Use metal-to-metal adhesive between lining aluminium lamination 1 described in it and carbon steel layer 2, polyethylene layer 5 all adds fire retardant and Conductive carbon powder, reinforced pipe pipeline outer wall flame-retardant and anti-static performance.
The utility model has following beneficial effect:
Good mechanical property.Because internal layer and base tube are metallic material, so its resistance to compression, impact resistance is strong, tensile strength is large, elongation percentage is high, and elastic mould value is high, and thermal expansion coefficient is little; Adhesive strength is high.Be be inserted in steel pipe by the aluminum pipe of internal layer, under the effect of mechanical force, make outer carbon steel tube resiliently deformable, the plastic deformation of internal layer aluminum pipe, the effect of adding metal-to-metal adhesive makes two-layer material closely be fitted together to, its more than adhesive strength 15Mpa.Make its peeling strength high under 3PE anticorrosive coat Ji Xie Clamp-on conjunction, chemical bond, diffusion, the acting in conjunction of electrostatical binding power, peeling strength >=100N/10mm(20 ± 2 DEG C), through drop impact and tearing, without destroying; Antirust corrosion-proof is good.Aluminium material, owing to having excellent rustproof property, makes steel pipe inner wall be not easy corrosion, and the 3PE layer of outer wall subjected to the inspection of harsh service condition at oil and gas industry, its antiseptic property is very superior; Anti-static agent and fire retardant is all added with, the surface that it is antistatic, flame-retardant composition is evenly distributed in tubing in product outermost surface polyethylene coating formula.Use in gas pipeline and coal mine gas drainage pipe road and there is very large advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-serves as a contrast aluminium lamination, 2-carbon steel layer, 3-epoxy powder layer, 4-adhesive layer, 5-polyethylene layer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Steel pipe is after impeller blasting process, first at pipe inner-wall spraying metal-to-metal adhesive, be inserted in thin-wall aluminium pipe again through row mechanical presses, make outer carbon steel tube resiliently deformable, the plastic deformation of internal layer aluminum pipe, the effect of adding metal-to-metal adhesive makes two-layer material closely chimeric formation lining aluminium lamination 1, then intermediate frequency heater is opened, after intermediate frequency heating collar reaches setting temperature, by running roller turning handle steel pipe through heating in medium frequency circle, when steel pipe front end is sent to spray gun rifle head, open electrostatic spraying gun, to outer wall of steel pipe through the electrostatic spraying of row epoxy powder, epoxy powder is solidification in the middle of advance, form epoxy powder layer 3, when steel pipe front end arrives the head of adhesive extruder, open adhesive extruder, outer wall of steel pipe epoxy powder layer 3 is wound around adhesive layer 4, continue again to run forward, when steel pipe front end arrives the head of polyethylene extruder, open polyethylene extruder, adhesive layer 4 is wound around polyethylene layer 5, described polyethylene layer 5 adds fire retardant and Conductive carbon powder, reinforced pipe pipeline outer wall flame-retardant and anti-static performance.
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.
