Abstract
Hot galvanizing flame-retardant and anti-static composite steel tube in a kind of outer 3PE, is characterized in that: pipeline is made up of zinc coat, carbon steel layer, epoxy powder layer, adhesive layer, polyethylene layer; Polyethylene layer described in it 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 hot galvanizing flame-retardant and anti-static composite steel tube of one.
Background technique
At present, widely used 3PE anti-corrosive steel tube in oil and gas pipeline, obtains the accreditation in market with its superior corrosion-resistant, water resistant permeability to gas and mechanical property.But its anticorrosive coat is only limitted to outer wall of steel pipe, and 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 be applied to underground coal mine.
Common steel tube is on the basis of surface pretreatment, and steel pipe is put into hot dipping groove, with the galvanizing flux of melting, complicated physics, chemical reaction occurred, and forms corrosion resistant hard-packed zinc-iron alloy layer.Gather outer wall 3PE aseptic technic again, form that a kind of antiseptic property is excellent, the novel tube of strong adhesion, long service life, completely flame-retardant and anti-static.
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 hot galvanizing flame-retardant and anti-static composite steel tube.
Its technological scheme is as follows:
A kind of outer 3PE hot galvanizing flame-retardant and anti-static composite steel tube.It is characterized in that: pipeline is made up of zinc coat 1, carbon steel layer 2, epoxy powder layer 3, adhesive layer 4, polyethylene layer 5; Polyethylene layer 5 described in it 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:
The utility model is integrated with the premium properties of 3PE aseptic technic and hot dipping zinc pipe.Corrosion-resistant, strong adhesion, anti-aging, flame-retardant and anti-static, inner wall smooth non-scaling.Because inwall is that galvanizing alloy-layer adhesion is extremely strong, when completely solving steel-plastic composite pipeline use, there is scaling, cause the problem of transporting system major hidden danger.For gas extraction and the desirable tubing of natural gas transport.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-zinc coat in figure, 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, put into hot dipping groove, carry out hot dip galvanizing process, form inside and outside zinc coat, again outer wall of steel pipe zinc coat shot-blasting machine is removed, only stay inwall zinc coat 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.
