A, process characteristics of FRP pipe
1, craft FRP pipe has excellent physical performance, FRP pipes proportion of 1.8-2.1, approximately 1/4 of steel, steel, cast iron and plastic than than high strength, FRP pipe weight generally is not more than the same specifications of steel 1/3, physical and mechanical performance is excellent, in addition, glass steel tube coefficient of expansion and steel approximately equal, heat conduction coefficient only steel 0.5%, is a kind of very good heat and electrical insulators.
2, craft glass steel tube chemical corrosion-resistant, long service life, suitable for conveying for all types of acid, alkali, salt and organic solvents and other different medium.
3,. Process FRP pipe hydraulic characteristics of excellent, hydraulic characteristics is one of the most important features in glass tube. The hydraulic characteristics excellent means fluid pressure head losses small, can choose smaller diameter or smaller power transmission pumps, thus reducing pipeline engineering initial investment, save electricity and reduce the operating cost. FRP inside surface quite smooth, general surface coarse rate desirable, almost can 0.008 think is "hydraulics smooth tube," in operation, steel, cast iron pipe, cement tube as the inside surface, often happen localized corrosion and become more and more rough, but always maintain the newborn FRP pipe must smooth surface condition.
4, craft glass steel pipe installation, maintenance cost low, generally speaking, the glass tube don't need particular anticorrosive processing, Insulation layer can reduce thin, even not another heat treatment; Piping comparatively light, small tonnage of hoisting equipment, power consumption, glass steel tube length less than cement pipe and cast iron, the connector length, relative low, these will reduce installation and maintenance costs, which has been proved by many domestic engineering practice.
5, craft glass fiber reinforced plastic piping design big agility and modifications cycle is short. Glass fiber reinforced plastic resin is to soak have to fiber strength materials, according to the specific process conditions layered clinging to mandrel and proper curing made, wall is a layered structure, by changing the resin system or adopt different reinforced materials to adjust glass steel pipe of various physical and chemical properties, to meet the different medium and working conditions made for different pressure levels or has some special properties of glass tube. Retrofit cycle is short, a fiber filament-wound composite remarkable characteristic, isotropic metal pipes material cannot compared to.
