Abstract

The utility model relates to a carbon-plastic alloy fire-retardant temperature resisting oil-gas pipe material, the pipe wall of which is composed of an inner lining pipe of an inner layer, a reinforcing layer of a middle layer and a protective layer of an outer layer, wherein the inner lining pipe is composed of a pipe body which is made of carbon fiber, filament chopped material, graphite, plastic mixing granulation in an extrusion way. The reinforcing layer is formed by winding filament fibers, and adhesive agglutinates between the fibers. The protective layer is wound by sticky cotton, bonded by resin and pressed polish. The utility model is mainly used for transporting oil, gas, water and other chemicals, and can substitute the existing steel pipe. The utility model has the advantages of smooth inner wall, small flow resistance, strong oil transportation ability which is enhanced by 25 to 30% than the steel pipe, light weight which is 30% of that of the steel pipe, no micro leakage, no scale formation, flame resistant, thermal insulation, antistatic performance, no delamination, and long service life; the abrasion resistance of the utility model is 6 to 8 times of the steel pipe, and the fluid loss is lower than the steel tube by 30%; the utility model is suitable to the working temperature-40 DEG to 105 DEG, and the inner side and the outer side are anti-corrosive. The utility model has good adaptability to non-oxidizing acid, sulfuric acid, dilutes nitric acid, alkali, saline solution and various corrosive medium in high temperature condition.

Description

The fire-retardant heatproof oil-gas pipe material of a kind of carbon-plastic alloy
Technical field
The utility model relates to a kind of tubing, particularly a kind of flame-resistant high-temperature-resistant tubing.Be mainly used in transferring oil, gas, water and other chemical formulation, alternative existing steel pipe.
Background technique
Be used for carrying the pipeline of above-mentioned liquid gas medium all to adopt steel tube at present, there is following shortcoming in steel tube:
Inner wall coarse, flow resistance are big, and transporting efficient is low; Than great, during installation fee, effort; Body is little to be oozed, and easily fouling is low wear-resisting; Thermal insulation property is low, easily delamination, and heat-energy losses is big; Adapt to the Korrosionsmedium ability.Working life is short, is 3-6.
Novel content
The purpose of this utility model just provides a kind of flame-resistant high-temperature-resistant tubing, to overcome the above-mentioned shortcoming that steel tube exists.
The technological scheme of taking of the present utility model is as follows: the fire-retardant heatproof oil-gas pipe material of a kind of carbon-plastic alloy, its tube wall comprises three-layer composite structure, is respectively the internal lining pipe of internal layer, the enhancement layer in middle level, outer field protective coating.
Described internal lining pipe is made of the body that adopts carbon fiber, long filament weak point to cut material, graphite, the extruding and moulding of plastics mixing granulation.
Described enhancement layer is that long fiber is wound in, and adhesive bond is arranged between the fiber.
Described protective coating adds resin-bonded by sticking cotton winding and press polish constitutes.
The utility model has the advantages that: inner wall smooth, flow resistance is little, and roughness only is 1/100 of a steel pipe, and friction ractor is 60% of a steel pipe, and oil transportation can improve 25%-30% by the force rate steel pipe.
In light weight, be 30% of steel pipe weight, pliability is moderate, can save equipment and labour cost 60%.No little oozing, non-scaling, wear-resisting property are 6-8 times of steel pipe, and fluid loss is than steel pipe low 30%.Fire-retardant, insulation, antistatic, not delamination, coefficient of heat transfer is low only to be 1/200 of steel pipe.Adapting to operating temperature is-40 ℃-105 ℃.
Internal and external anti-corrosive, to non-oxidizing acid, sulfuric acid, rare nitric acid, 275 kinds of Korrosionsmediums of alkali and salt solution and organic solvent at high temperature have good adaptability, and special the adaptation, use under rugged environment.Long service life: be 20-30 under design temperature pressure.
Description of drawings
Fig. 1 is a cross-sectional configuration schematic representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is by from the inside to the outside internal lining pipe 1, enhancement layer 2 and protective coating 3 compound formations.
Described internal lining pipe 1 adopts carbon fiber, long filament weak point to cut material, graphite, plastics mixing granulation extruding and moulding manufacturing and forms.
Described enhancement layer 2 adopts long fiber to be entwined, and adhesive bond is arranged between the fiber.
Described protective coating 3 adopts sticking cotton winding to add resin-bonded and press polish forms.
Internal lining pipe 1 of the present utility model have noly littlely ooze, high abrasion, good toughness, low temperature resistant performance.
Enhancement layer 2 intensity height of the present utility model, and protective coating smooth surface, protective is good.
