Abstract
The invention discloses a method for manufacturing a steel, plastic, glass-fiber three-layer composite pipe, comprising the following steps of: firstly, a plastic pipe is inserted into a steel pipe to form a steel-plastic composite pipe; then, the steel-plastic composite pipe is fixed to a rotating shaft of a winding machine to rotate at a constant speed; a glass-fiber device for sending and immersing resin is started to immerse multiple strands of glass fibers into resin and then uniformly and tightly wind the obtained glass-fiber resin on the outer wall of the steel pipe, and reciprocates axially along the rotating steel-plastic composite pipe at a constant speed; and finally, the glass-fiber resin is heated when reaching the required thickness so as to be solidified to form a glass-fiber resin pipe outside the steel pipe, and then is taken down from the winding machine completely, i.e., the manufacturing of the steel, plastic, glass-fiber three-layer composite pipe is completed. The method for manufacturing the steel, plastic, glass-fiber three-layer composite pipe is simple and convenient, so that a high-quality and long-life three-layer composite pipe can be produced fast by the method.
Description
Technical field
The present invention relates to multiple tube, specifically a kind of steel is moulded the preparation method of glass three-layer composite pipe.
Background technology
Oil field developments such as China's grand celebration, triumph, North China, Central Plains get into the middle and later periods, and water content is bigger, and Shengli Oil Field part block is moisture to reach 95%, the produced-water reinjection stratum after the water-oil separating, and pressure is high and corrosivity is strong, and the steel pipe life cycle is short; Use to annotate polymerizing technology during old filed produces on taping the latent power, obtain gratifying effect, but high pressure polymer injection severe corrosive and abrasion make in the steel pipe anticorrosive coat by quick-wearing very, corrode very fast; Service life is short, has increased development cost, for this reason; Test replaces steel pipe with high-pressure glass fibre reinforced plastic pipe, has obtained certain progress once at 12MPa, has solved etching problem; Can't use because of pipe shaft infiltration under fiberglass (fiberglass resin) the pipe high pressure but 20MPa is above, glass reinforced plastic pipe resists the outer ability of impacting simultaneously, and anti-water attack property is poor; Difficulty of construction is big, and hardening time is long, has caused very big difficulty for pipeline modification and accident maintenance.
In the prior art; The open source literature that can address the above problem comprises following: the patent No. is 200710013071; 200720017449,200720017450 and 200920020636 etc., the described glass fibre resin-immersing composite pipe of above open source literature; Because of internal layer is a metal, be prone to fouling, perishable on engineering, the application; Described polythene glass fibre resin-immersing composite pipe; Annotated to gather in the pipeline at the Shengli Oil Field high pressure and used; Solved extreme pressure (can reach 70MPa) infiltration and corrosion and wear problem, but its construction requirement is high, difficulty is big, joint long influence hardening time promoted the use of.
Certainly outside the above-mentioned multiple tube that glass fibre is set steel pipe; People more are to rest on disclosed already steel-plastics composite pipe or plastic-aluminum pipe to the understanding of multiple tube; Be that plastic tube is all to have formed known technology in the outside or the inside of steel pipe; Such as the patent No. is open source literature such as 99112265,99221210,99222235,00256989,01218329,02269391; So people have reason to expect in steel duct plastic tube being set, then at steel pipe outer setting glass fiber resin pipe.But this three-layer composite pipe also do not occur at present, the preparation method that does not more have this three-layer composite pipe is known by people.
In view of this, to the problems referred to above, the preparation method that the steel of the above-mentioned disappearance of a kind of effective improvement is moulded the glass three-layer composite pipe is proposed.
Summary of the invention
The object of the present invention is to provide steel to mould the preparation method of glass three-layer composite pipe; Utilize the shock resistance external force resistance damage capability of high strength and steel pipe of anti-corrosion, anti-wear performance, glass fiber resin of plastic tube strong, be convenient to fast link and the good characteristics of each mechanical property, process steel and mould the glass three-layer composite pipe.This method is simple and convenient, the said three-layer composite pipe that the quality of production is high fast, the life-span is long.
In order to reach above-mentioned purpose, the invention provides the preparation method that steel is moulded the glass three-layer composite pipe, its step is following:
1) forms steel-plastics composite pipe among at first plastic tube being interspersed in steel pipe; Be fixed on steel-plastics composite pipe on the rotating shaft that twines machinery and make its uniform rotation;
2) startup is sent and is soaked fat glass device, with evenly being wrapped in closely on the outer wall of steel pipe behind the glass fibre multiply immersion resin, send resin pickup glass device at the uniform velocity to do axially reciprocating along the steel-plastics composite pipe of said rotation;
3) glass fiber resin reaches desired thickness and makes it solidify the back through heating and forms the outside glass fiber resin pipe of steel pipe, then integral body is mechanically taken off from twining, and steel is moulded the glass three-layer composite pipe and promptly completed.
The thickness of said glass fiber resin pipe is directly proportional with the diameter of three-layer composite pipe and needed pressure; Wherein thickness is 1-30mm, and the number range 20-1500mm of diameter, three-layer composite pipe bearing capacity are 1-110MPa; Fluid cross-section is directly proportional by axial force under steel pipe thickness and the three-layer composite pipe working pressure; Wherein steel pipe thickness is 2-10mm, and the inner plastic tube thickness is with self diameter and make things convenient for the melting welding degree to be directly proportional, and the inner plastic tube thickness is 2-15mm.
Said resin is the mixture of unsaturated polyester resin and curing agent, and unsaturated polyester resin divides resins for universal use, chemically-resistant resin and flexible resin; Unsaturated polyester resin cold curing agent is peroxidized t-butyl perbenzoate or methyl ethyl ketone peroxide; Add the promoter of quickening usefulness in the unsaturated polyester resin solidification process, solidification temperature is 30-80 ℃, and be 3-20 hours said hardening time.
Said plastic tube material is the copolymer of high density polyethylene (HDPE) or polypropylene or LLDPE or ethene and acrylic acid copolymer or ethene and vinyl acetate.
Compared to prior art, the present invention is simple and convenient, the said three-layer composite pipe that the quality of production is high fast, the life-span is long.Certainly the steel of being produced is moulded the glass three-layer composite pipe and is thoroughly solved burn into abrasion, fouling and the rapid construction of pressure piping, rushes to repair and problem such as anti-outside destroy fast; The cycle of operation of pipeline is hopeful to bring up to 50 ~ 100 years; And, pipeline construction need not carry out the maintaining in later stage basically after accomplishing; Significantly reduced the maintenance cost in the running, the cycle of operation cost of pipeline reduces greatly.
