Description
Technical field
The invention belongs to multiple tube processing technique fields, and in particular to a kind of low flow resistance composite glass steel pipe and its processing side
Method.
Background technique
Tubing is very universal in daily life, and there are commonly feed pipe, drainpipe, gas pipe, steam heating pipe, electric wires to lead
Pipe, rain pipe etc., it is with the development of technology, the development experience of tubing plain cast iron pipe, pipe of cement, ductile iron pipe, zinc-plated
Steel pipe, plastic tube and aluminum plastic composite pipe etc..Wherein, for glass reinforced plastic pipe with its unique strong corrosion resistant performance, inner surface is smooth, conveying
The advantages that low energy consumption, long service life has been widely used in each field.
Traditional glass reinforced plastic pipe is using glass fibre and its product as reinforcing material, with unsaturated-resin, epoxy resin
Deng for basic material, the tubing being prepared using the inorganic non-metallics such as quartz sand and calcium carbonate granular materials as filler.It is made
Preparation Method has definite-length-winding process, centrifugal casting technique and continuous winding technique.But existing glass reinforced plastic pipe is whole strong
Spend lower, and the voltage endurance capability of tube wall is lower, so that can not be suitable for the conveying of high-pressure fluid；Further, traditional
In conveying high-pressure fluid, the frictional resistance of pipe material inner wall can improve glass reinforced plastic pipe, so that tubing is in conveying high-pressure fluid
When pressure drop it is excessive, fluid transportation energy consumption improve.
Summary of the invention
For the problems of the prior art, the purpose of the present invention is to provide a kind of processing of low flow resistance composite glass steel pipe
Method reduces the fluid transportation energy consumption of multiple tube.
To achieve the goals above, the present invention is achieved by the following scheme:

It is poured composite resin material, forms structure sheaf；
(3) outer mold is taken off, the second glass fiber-reinforced polymer of winding outside the structure sheaf, and in the second glass fibre of winding
The process of muscle, which applies tension to it, makes second glass fiber-reinforced polymer have prestressing force；
(4) outer protection materials are coated in the outside of the second glass fiber-reinforced polymer winding layer, then sloughs cylindrical inner mold tool, obtains
To the composite glass steel pipe.
In the present invention, liner layer is formed by the way that the first glass fiber-reinforced polymer to be spirally wound around on cylindrical inner mold tool, institute
On the inner surface for the liner layer stated by the first glass fiber-reinforced polymer it is spiral it is compact it is adjacent constitute, and in the first adjacent glass fibre
The groove formed between muscle is whole in the shape of a spiral in the length direction having along cylindrical inner mold, in the composite glass steel pipe finished product
During trandfer fluid, which advantageously forms vortex, to promote fluid compound quickly through glass reinforced plastic
Pipe reduces conveying energy consumption, reduces fluid by the pressure drop during the composite glass steel pipe.
Further, it is poured outside the structure sheaf to be formed in composite resin material and passes through the second glass fiber-reinforced polymer with prestressing force
Winding, so that the structure sheaf and liner layer to composite glass steel pipe form certain extruding force, which can offset one
Pressure when segment glass steel pipe conveying high-pressure fluid, improves the carrying pressure of the composite glass steel pipe, makes its satisfaction
The conveying requirement of high-pressure fluid.
Further, according to the present invention, the diameter of first glass fiber-reinforced polymer is 5~11mm.
In the present invention, in step (3), the diameter of second glass fiber-reinforced polymer is 3~6mm；And/or
