High quality of FRP sand-filled pipe

Our company produces a variety of quartz sand FRP winding pipelines and various process pipelines. Wherein the quartz sand FRP winding pipelines' specification is diameter 4000mm, 12000mm length or less , and the Process pipeline's specification is 300mm or less .The entire winding process is controlled by microcomputer, and has the characteristic of linear appearance, high accuracy, easy to operate.

The pipeline's working temperature is 40 degree to 80 degree,and the pipelines with special ratio can withstand 110 degree heat. Otherwise, frozen media does not crack the pipeline. If it used in middle and large traffic flow, the project cost ratio of large diameter quartz sand pipeline is 30% lower than the same diameter's. And it is about the same as the cement pipe, moreover, it has convenient transportation, low construction costs and no maintenance. Importantly it's life can be more than 50 years.

Characteristic:             

(1) Resistance to chemical corrosion, long life

FRP has special chemical corrosion resistance, and  FRP pipe products suitable for conveying different media of various acids, bases, salts and organic solvents, etc.

(2)Excellent physical and mechanical properties

The proportion of glass pipe material is typically 1.8-2.1g/cm², it is about steel 1/4-1/5, He is higher than that of steel, cast iron and plastic specific strength

The weight of the glass tube is generally not greater than the same size steel pipe 1/3, Excellent physics performance. Besides, Some physics properties of the glass pipe is quite advantageous, Thermal expansion coefficient and steel in general, and its heat transfer coefficient is only 0.5% of steel. In a word, it is a good thermal and electrical insulator.

(3)Excellent hydraulic characteristics

CONSERVANCY feature is one of the main characteristics of the glass pipe, which means the fluid pressure head loss is small, so you can use a smaller diameter or smaller power pump, finally can Reduce pipeline project initial investment, save energy, reduce operating costs.

The inner surface of the glass tube is quite smooth, surface roughness rate generally desirable 0.008, almost can be considered " hydraulic smooth pipe ". During operation, the inner surface of the steel pipe, cast iron pipes, cement pipes and so on, often localized corrosion, has become more and more rough, while the surface of the glass tube is always maintained smooth state newborn tube.

(4)Design flexibility and modified short cycle 

Glass pipe is impregnated with a resin matrix fiber reinforced material, layer by layer in accordance with the specific conditions tied to the core mold and is formed by proper curing. The tube wall is a kind of layered structure, which can adjust the physical and chemical properties of the glass tube by changing the resin system or using different reinforcing material. So it can accommodate glass pipes with  different pressure levels or have some special properties, which are made of Different media and working conditions. And modified cycle is short, it is a filament-wound composites notable features, all kinds of metal pipe can not exceed it.

(5)Low installation and maintenance costs

FRP pipe does not require special anti-corrosion treatment, Its heat preservation layer can be thinned, even do not need to do heat preservation. The pipe is relatively light, the tonnage of lifting equipment is small, and the power consumption is little. The length of the glass tube length is more than the cast iron and cement pipes, and Joint is relatively small, all these can reduce installation and maintenance costs, it is proved by so much practice of domestic and international engineering.

(6)Wide application field
