Abstract
The invention relates to once forming production equipment for an auto pressure-bearing super-long composite lining hose. The once forming production equipment comprises a braiding machine, wherein the upper part of the braiding machine is connected to an upper extruder through an inner coating mould; the lower part of the braiding machine is provided with a heater; an outer coating mould is arranged below the heater; the outer coating mould is connected with a lower extruder; cooling equipment is arranged below the outer coating mould; and a tractor is used for pulling products from the cooling equipment. According to the once forming production equipment, the lining hose can be formed once, and the produced lining hose is high in bearing capacity and is very soft; in a using process, even a fluid infiltrates into an enhancement layer, blasting is not affected, and the once forming production equipment is very easy to take up even the length is a few kilometers; and the once forming production equipment is very convenient to mount in a submerged pipeline or a U-shaped river pipeline, and the highest usage temperature can be as high as 150 DEG C.
Description
technical field:
The present invention relates to a kind of one-shot forming production equipment from pressure-bearing overlength compound lining flexible pipe, belong to fluid and transmit equipment technology field.
background technology:
Oil-gas pipeline, due to internal corrosion, causes pipeline service life not enough and even occur the risk of pipeline failure even causing serious leakage and security incident.This situation is of common occurrence in the industry in the whole world.Corrosion is the unavoidable phenomenon of metal material, causes body wall thickness constantly thinning therefrom, and even occurs risk of leakage, the integrality of threat tube.Emerge in an endless stream by corroding the pipe leakage accident caused, to normal production, the economical operation of enterprise, and even the safety of enterprise and periphery society constitutes great threat.Non-metallic inner liner can fundamentally solve corrosion of metal problem.But convention liner flexible pipe is all the liner hose be made by rubber or resin-made, and operation is many, transport is inconvenient, and the limitation of length, bearing capacity is not high, has handling safety hidden danger.
summary of the invention:
The object of the invention is to provide a kind of one-shot forming production equipment from pressure-bearing overlength compound lining flexible pipe for above-mentioned Problems existing, make liner hose can one-shot forming, the liner hose ability to bear of producing is high, very soft, even if also do not affect explosion in fluid permeability to enhancement layer in use procedure, length several kilometers and rolling are light especially, though the pipeline sunk or U-shaped river Pipe installing also very convenient, maximum operation (service) temperature can reach 150 DEG C.
Above-mentioned object is achieved through the following technical solutions:
From the one-shot forming production equipment of pressure-bearing overlength compound lining flexible pipe, comprise braider, described braider top connects upper extruder by interior painting mould, described braider bottom is provided with heater, outer painting mould is provided with below described heater, described outer painting mould connects lower extruder, is provided with cooling device below described outer painting mould, with hauling machine traction from cooling device product out.
The described one-shot forming production equipment from pressure-bearing overlength compound lining flexible pipe, described heater outer setting has heat-insulation layer.
The described one-shot forming production equipment from pressure-bearing overlength compound lining flexible pipe, described lower extruder has two, is connected to the both sides of described outer painting mould.
The described one-shot forming production equipment from pressure-bearing overlength compound lining flexible pipe, described interior painting mould comprises interior painting mould core and interior painting mould die sleeve, the top of described interior painting mould die sleeve is coated with die feeding mouth in being provided with and being connected with upper extruder, and described interior painting mould core and interior painting mould die sleeve extend downwardly in described heater.
The described one-shot forming production equipment from pressure-bearing overlength compound lining flexible pipe, described outer painting mould comprises outer painting mould core and outer painting mould die sleeve, and described outer painting mould die sleeve both sides have the outer painting die feeding mouth be connected with described lower extruder respectively.
Beneficial effect:
The invention enables liner hose can one-shot forming, the liner hose ability to bear of producing is high, very soft, even if also do not affect explosion in fluid permeability to enhancement layer in use procedure, length several kilometers and rolling is light especially, even if sink pipeline or U-shaped river Pipe installing also very convenient, maximum operation (service) temperature can reach 150 DEG C.
