Mainly used for water, sewage, petroleum, chemical, electric power, metallurgy, medicine and other fields of filament wound FRP pipe, has the advantages of light weight, high strength, strong corrosion resistance, convenient installation, maintenance etc.. The product has been successfully used with all parts of the country.

A, glass steel sewage pipeline characteristics

1, have excellent physical properties, glass steel pipe for the proportion of 1.8-2.1, about 1/4 steel, steel, cast iron and plastic than the high strength glass steel pipeline, the general weight of not more than the same specification of steel 1/3, excellent physical and mechanical properties, in addition, glass steel pipe expansion coefficient and steel roughly, 0.5% the heat conduction coefficient only steel, is a good thermal and electrical insulators.

2, chemical corrosion resistance, long service life, suitable for conveying various acid, alkali, salt and organic solvent in different media.

3, excellent hydraulic characteristics, hydraulic characteristic is one of the important characteristics of FRP pipe. The hydraulic characteristics of the excellent means that the fluid head loss is small, pump can use a small diameter or smaller power, thereby reducing the pipeline project initial investment, save energy, reduce the operating cost. Glass reinforced plastic inner surface is quite smooth, the general surface roughness can be 0.0084, almost can be thought of as "hydraulic smooth pipe", in operation, the inner surface of steel pipe, cast iron pipes, cement pipes and so on, often local corrosion, becomes more and more rough, and the glass steel has always maintained a new tube smooth surface state.

4, installation, low maintenance cost, generally speaking, the glass steel pipe does not need the antiseptic treatment; thermal insulation layer can be thinned, even without the other do heat preservation; the pipeline is quite light, the hoisting equipment tonnage is small, power consumption is small, the glass steel pipe length than the cement pipe and cast iron pipe length, the joint is to reduce, these will reduce the installation and maintenance costs, which has been proved by many engineering practice at home and abroad.

5, design flexibility, short cycle of modification. FRP is impregnated with a resin matrix fiber reinforced materials, according to the specific technological conditions of layer by layer winding on a mandrel and made proper curing, tube wall is a kind of layered structure, can use different enhancement material to adjust the glass pipe and the physical and chemical properties of the resin system or change, to adapt to the glass steel of different medium and different working conditions made pressure rating or has some special properties. Retrofit cycle short, the fiber winding composite material is the remarkable characteristics of the metal pipe, the isotropic can compare.
