Abstract
The invention discloses a novel steel-lined composite pipe fitting made of polytetrafluoroethylene. The novel steel-lined composite pipe fitting made of the polytetrafluoroethylene comprises a pipe body consisting of an inner layer, a steel pipe layer, a fiber-reinforced layer and an outer layer from inside to outside, both the inner layer and the outer layer are made of the polytetrafluoroethylene by processing, and the fiber-reinforced layer is a glass fiber reinforced layer. The novel steel-lined composite pipe fitting made of the polytetrafluoroethylene has the advantages that under the effect of the inner polytetrafluoroethylene protecting layer and the outer polytetrafluoroethylene protecting layer, ageing resistance, high-temperature resistance and corrosion resistance of a pipe fitting body of the composite pipe fitting can be improved greatly, and corrosion of most substances including concentrated nitric acid and nitromuriatic acid can be resisted; and high-pressure resistance of the pipe fitting is improved effectively under the effect of the glass fiber reinforced layer, and accordingly use effect of the pipe fitting is improved greatly.
Description
Technical field
The present invention relates to a kind of tubing, particularly a kind of novel steel lining teflon composite pipe fitting.
Background technique
The steel lining composite pipe, be with the normal carbon steel pipe as matrix, the thermoplastic pipes that the liner chemical stability is good is through cold drawn compound or rotationally molding.The mechanical property of its existing steel pipe has the corrosion-resistant of plastic tube again, slow fouling, and the characteristics of difficult growth microorganism are the ideal conduit of carrying acid, alkali, salt, the media such as gas that are corrosive.Extensively applied to medium transport and the environment-friendly disposal system of industries such as chemical industry, electric power, metallurgy, food.Along with industrialized fast development, the steel lining composite pipe has more and more stricter requirement for aspect such as high pressure resistant, corrosion-resistant, high temperature resistant.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of novel steel lining teflon composite pipe fitting is provided, promote the performance such as high pressure resistant, corrosion-resistant, high temperature resistant, ageing-resistant of tubing, improve its using effect.
Purpose of the present invention realizes like this:
A kind of novel steel lining teflon composite pipe fitting of the present invention comprises body, wherein, is made of from inside to outside internal layer, steel pipe layer, fiber-reinforced layer, skin in the described body; Described internal layer and skin are teflon and process; Described fiber-reinforced layer is glass fiber reinforced layer; Described steel pipe layer is for to be made of seamless steel pipe.
Above-mentioned a kind of novel steel lining teflon composite pipe fitting, wherein, described internal layer and outer layer thickness are about 3-4.5mm.
Above-mentioned a kind of novel steel lining teflon composite pipe fitting, wherein, described glass fiber reinforced layer thickness is about 1.5-2mm.
Compared with prior art, the present invention has the following advantages:
1) by the effect of inside and outside polytetrafluoroethylene floor, can play good protection, there is remarkable effect aspect such as ageing-resistant, high temperature resistant, corrosion-resistant.Particularly all chemical mediators almost can be resisted in corrosion-resistant aspect, comprise the corrosion of red fuming nitric acid (RFNA) and chloroazotic acid.
2) effect of glass fiber reinforced layer further improves the intensity of tubing, effectively improves its high voltage performance.
A kind of novel steel lining teflon composite pipe fitting of the present invention by the effect of inside and outside teflon protective layer, can improve the ageing-resistant, high temperature resistant, corrosion-resistant of composite pipe tubing greatly, can keep out the overwhelming majority's corrosion that comprises red fuming nitric acid (RFNA) and chloroazotic acid.The effect of glass fiber reinforced layer has then effectively improved the tubing high voltage performance, has improved the using effect energy of tubing greatly.
