Abstract
The present invention discloses a technique for producing a corrosion-resistant and pressure-resistant composite pipe (glass fiber reinforced plastic and a steel pipe) with the utilization of an inflated annular cylindrical capsule, and a device thereof, wherein the glass fiber reinforced plastic which is not solidified and coated on the outer surface of the capsule is compounded with the inner wall of the steel pipe by controlling the internal pressure of the capsule. The technique and the device are simple; the composite pipe (the glass fiber reinforced plastic and the steel pipe) produced by the technique and the device has the advantages of strong compounding force, corrosion resistance, pressure resistance, good social benefit and good economic benefit.
Description
The present invention relates to a kind of production technology and combination process device thereof of anti-corrosion composite pressure pipe.
The manufacturing process of anti-corrosion composite pressure pipe has outer tube to contract through method (drawing take turns forge outer tube), interior pipe heating (steel is moulded the heating of compound tense internal plastic tube, during the steel pipe rubber lining, the heating of tubulose sizing material), gunite process materials such as () steel pipe inwall spraying cements at present both at home and abroad.Above-mentioned technology, the technological equipment that has is huge, complex process, energy consumption is big.The finished product life-span that the explained hereafter that has is come out is short, cost height, corrosion resistance difference etc.
The objective of the invention is: for glass fibre reinforced plastics, steel pipe is compound that a kind of novel combination process and device are provided, and produce anti-corrosion, composite pressure pipe.
Combination technological method of the present invention is: to circular cylinder capsule pressurization (inflation), utricule is expanded, when utricule expand into outer diameter and is slightly less than the steel pipe inner diameter, stop pressurization, with resin, glass fiber cloth is around form tubular glass steel pipe (uncured) to capsule, axially be adjacent to glass fiber cloth with 8 seizing wires, resin, strain with the termination tensioning means, this moment, intraluminal pressure needed constantly to adjust, when the capsule maximum outside diameter (comprises resin, pressure regulation stops when fibre cloth) being significantly smaller than pipe diameter, load onto circular cylinder capsule guiding device, be pushed in the steel pipe after the processing, after two ends and the steel tube head locking, for the second time capsule pressurizeed, loosen seizing wire simultaneously, utilize to extract seizing wire out and discharge gas between steel pipe inwall and the uncured glass fibre reinforced plastics of tubulose.When the capsule internal pressure reaches certain value, the cut-out pressure source, treat that uncured glass fibre reinforced plastics and the gelling of steel pipe inwall are solidified after, take out utricule, steel pipe, glass fibre reinforced plastics is compound finishes.
Device of the present invention is made up of circular cylinder capsule, axle center pipe, sealing termination, seizing wire, tensioning means etc., one axle center pipe is arranged in the circular cylinder capsule, one inlet hole pipe is arranged in the pipe of axle center, respectively there are some positioning pin holes at pipe two ends, axle center, 8 blocks of movable sealing plates and 16 springs are equipped with in sealing inboard, termination, 8 seizing wires are through the circular cylinder capsule outside and sealing termination, one end is connected with support brace, the other end is connected with tensioning means by guide plate, tensioning means and axle center pipe are radial fit, and its inside is Spielpassung.
Advantage of the present invention is technology and installs easyly, practical that composite pipe (glass fibre reinforced plastics, the steel pipe) composite force of utilizing this technology and device to produce is strong, has good society and economic benefit.
Fig. 1 is a combination process flow chart of the present invention.
Fig. 2 is a combination process apparatus structure schematic representation of the present invention.
(1) axle center pipe, (2) seizing wire, (3) guide plate, (4) steel pipe, (5) glass fibre reinforced plastics, (6) capsule, (7) balance support ring, (8) movable sealing plate, (9) spring, (10) capsule bounding means, (11) sealing termination, (12) support brace, (13) inlet hole pipe, (14) tensioning means among Fig. 2.
The invention will be further described below in conjunction with drawings and Examples.
Before the invention process, carry out part component-assembled (seeing process flow diagram square frame 1) earlier, assembling finishes, by inlet hole pipe (13) in capsule (6), pressurize (qi of chong channel ascending adversely), capsule is expanded, when utricule expand into outer diameter and is slightly less than steel pipe (4) inner diameter (intended diameter), apply release materials earlier, glass fiber cloth is twined in the back, apply resin again, be uncured glass fibre reinforced plastics (5) (uncured glass fibre reinforced plastics has formed tubular body), when reaching design thickness, axially be close on uncured glass fibre reinforced plastics (5) surface with 8 seizing wires (2), seizing wire (2) one ends and support brace (12) are connected and fixed, the other end is connected and fixed by guide plate (3) and tensioning means (14), rotation tensioning means (14), make seizing wire (2) tighten and do radial displacement, seizing wire (2) is then oppressed capsule (6), capsule (6) is because the external force effect, the interior pressure increases and distortion (girth is constant), need to adjust intraluminal pressure (release of pressure) this moment, after treating that the pressure adjustment is finished, when capsule (6) maximum outside diameter (comprising uncured glass fibre reinforced plastics (5)) is significantly smaller than steel pipe (4) internal diameter, load onto guiding device and push in after treatment the steel pipe (4), during location-appropriate, loosen seizing wire (2), lay down tensioning means (14) and guiding device, load onto sealing termination (12) and locking, in capsule, pressurize again, but the limit added flanging and took out seizing wire (2) this moment, thereby reach the gas of discharging between steel pipe inwall and the uncured steel of tubulose, seizing wire (2) is loaded onto sealing block after all extracting out, when capsule (6) internal pressure arrives design load, pressurization stops, treating that glass fibre reinforced plastics solidifies after, take out
Claims (3)
