Abstract
A kind of oil well carbon silica gel high pressure wire braided hose comprising interior sebific duct, the interior sebific duct is mainly by being that 10-16% carbon, 42-53% silica gel, 12-18% Nano graphite and 22-27% nitrile rubber component are constituted with mass percent;Steel wire organization level is set on the outside of the interior sebific duct, canvas layer is set between the steel wire organization level and interior sebific duct, the canvas layer is two-sided brushed with the sub- glue of slurry, it starches in sub- glue and contains bind enhancer, the canvas layer and steel wire, which is compiled into, is repeated in three layers or more, gauge of wire is 1-2mm, adjacent steel wire organization level is wound with opposite repercussion, the helical angle of winding is 45 degree or so, the outermost steel wire organization level is externally provided with spongy layer, spongy layer is tightened by gauze winding, the spongy layer is externally provided with non-metallic wear resistant layer, non-metallic wear resistant layer is bellows composition.The present invention can be from subzero tens degree to tens degree above freezing to the adaptation of temperature, and warm season limit of not being bullied, service life greatly improves.
Description
Technical field
The invention belongs to petroleum technology fields, especially provide a kind of oil well carbon silica gel high pressure wire braided hose.
Background technique
During well workover, often carry out conveying high-pressure fluid using to high-pressure hose.It is roughly divided into two processes,
It is generally made of General Purpose Rubber or plastics in high-voltage tube a few years ago, the pipeline of plastic material can not be arbitrarily bent, for needing pipe
The general selection rubber material of the random folded bent in road, but the general wearability of sebific duct, intensity, ageing resistance is made all in General Purpose Rubber
Lower, especially the service life of hose is shorter during high-pressure delivery;Technical staff had invented high pressure steel volume in recent years
Sebific duct is generally exactly in internal layer or outer layer setting sebific duct, and middle layer improves intensity with steel wire braid, further according to the need of function
Some functional layers are set wherein, for example form flame-retardant layer using fire proofing, form heat-insulated thermosphere etc. using heat-barrier material,
Its various performance all greatly improves, such as Publication No. CN206054980U, publication date 2017.03.29;
The fire-retardant high pressure steel wire of oil resistant disclosed in CN204533877U, the Chinese utility model patent that publication date is 2015.08.05 weaves glue
Pipe, relatively common rubber hose, the characteristics such as Gao Shuiwen strong with acid resistance, resistance to, oil resistant, wear-resisting.But above-mentioned high pressure steel
Silk braided construction hose be restricted in terms of climate temperature, general hot weather construction operation, it is above freezing to thirty or forty degree can normal operation
Construction, but begin to bulge, husking or even crack occur to autumn and winter temperature to subzero construction operation fuse, especially
It the use of the crack occurred is even more frequently to occur in the Northern Hemisphere in winter, such as Northeast Area of China, the lower place performance of temperature
It is more obvious.Crack causes high-pressure hose to leak, and unbearable high-pressure fluid not only misses especially in the pressure of 15MPa or more
Work is mistaken, and also pollution environment, cost are also higher.The main reason for causing the above problem is that material selection is incorrect, can not be resisted tight
It is cold, low-temperature resistance.As Daqing oil field recover the oil nine operation groups, the factory high pressure rubber hose braided with steel wire that has a Φ 51*4*20 specification used less than
Occur within three months bulge 18, it is small such as walnut as large as egg;There are also a similar sebific ducts to use husking nearly three in two months
Rice, has seriously affected production and its personal safety, has caused serious economic loss.These problems all need to improve.
Summary of the invention
The present invention solve above-mentioned technical problem, a kind of oil well carbon silica gel sebific duct is provided, keep it is good it is wear-resisting,
Acidproof, oil resistant, it is anti-aging on the basis of, can not be bullied the warm season from subzero tens degree to tens degree above freezing to the adaptation of temperature
Section limitation, service life greatly improve.
The present invention solves the technical solution that technical problem uses:
