Erosion, brings huge potential safety hazard to the conveying of combustion gas, and although brushing paint can solve the problem that certain Anticorrosion Problems, but brush
Paint unsightly, easily pollutes environment, and painting needs periodically brushing to safeguard, brings huge maintenance cost to enterprise.
If using stainless-steel pipe, one is high cost, should not be used in a large number, especially large-size stainless steel steel pipe, into
Ben Genggao;But Site Welding difficulty of construction is big, it is necessary to use special stainless steel electrode, cost is very high;Three is special at some
Occasion, if any the occasion that chlorine or chloride ion are present, its corrosion resistance is very poor, short life;Four is that safety is poor, a large amount of built on stilts
The natural gas tube of installation, is such as not added with protection, is easily attacked by thunder and lightning.
Existing gas pipeline is all mainly to arrange anticorrosive coat in outer layer, and ignores the anti-corrosion of internal layer.Due in combustion gas
Containing certain moisture and H2Corrosive harmful constituent such as S, chloride, can cause the internal corrosion of pipeline, and internal corrosion is to cause
One of the reason for tubing serious aging, pipe leakage will be caused, and reduce structural strength, and seriously threaten whole gas transmission system
Safety, integrity and economy.
Utility model content
This utility model purpose is to provide a kind of high-weatherability anti-corrosion fire prevention gas pipeline, solves existing gas pipeline and holds
Easy internal corrosion and the problem of external corrosion.
The technical solution of the utility model is:A kind of high-weatherability anti-corrosion fire prevention gas pipeline, including steel pipe, steel pipe inner wall
Polytetrafluoroethylene floor is provided with, outer wall of steel pipe has two-layer compound protective layer, epoxy of the two-layer compound protective layer by internal layer
The basalt fiber of resin bed and outer layer is constituted.
Further, the polytetrafluoroethylene floor is the polyfluortetraethylene pipe for being set in steel pipe inner wall, polyfluortetraethylene pipe
Pipe thickness be 1-2mm.
Further, LDP-600 fire protection pipeline special epoxy anticorrosion of the epoxy resin layer using ippon paint company
Powder coating.
Further, the thickness of epoxy resin layer is 200-250um.
Further, basalt fiber is made up of the basalt fibre weaving cloth being coated on outside epoxy resin layer.
This utility model is had the advantage that compared with prior art:
This utility model steel duct arrange polytetrafluoroethylene floor, due to politef resistance to chemical corrosion it is excellent
It is different, combustion gas can be prevented to the corrosion inside pipeline, pipeline outer wall is provided with two-layer compound protective layer, and epoxy resin has resistance toization
Product corrosion, good mechanical performance and resistance to elevated temperatures, so as to provide excellent anti-corrosion and fire resistance property for pipeline;Basalt
Not only intensity is high for fibrous layer, but also has various excellent properties such as corrosion-resistant, high temperature resistant, and the anti-corrosion that can lift gas pipeline is prevented
Fiery performance.
