Common specifications and models of FRP process piping

1: Can be made according to user needs

2: Can be produced according to national standards

FRP process pipe is a new type of composite pipe with excellent performance. It has the incomparable performance of other traditional pipes (metal pipes, concrete pipes, plastic pipes).

Characteristics of FRP Process Pipeline

1. Process glass fiber reinforced plastic pipes have excellent physical properties. The specific gravity of glass fiber reinforced plastic pipes is 1.8-2.1, which is about 1/4 of steel. It has higher specific strength than steel, cast iron and plastics. The weight of glass fiber reinforced plastic pipes is generally not greater than that of steel pipes of the same specification. 1/3, excellent physical and mechanical properties. In addition, the expansion coefficient of FRP pipe is roughly equivalent to that of steel, and the thermal conductivity is only 0.5% of steel. It is a good thermal and electrical insulator.

2. Process glass steel pipe is resistant to chemical corrosion, has a long service life, and is suitable for conveying various acids, alkalis, salts and organic solvents and other different media.

3. Process FRP pipes have excellent hydraulic properties, and hydraulic properties are one of the important features of FRP pipes. Excellent hydraulic characteristics means that the fluid head loss is small, and a smaller pipe diameter or smaller power delivery pump can be selected, thereby reducing the initial investment of pipeline engineering, saving power, and reducing operating costs. The inner surface of FRP is quite smooth. Generally, the surface roughness can be 0.008, which can almost be regarded as a "hydraulic smooth pipe". During operation, the inner surface of steel pipe, cast iron pipe, cement pipe, etc. often undergoes local corrosion and becomes more and more Rough, while the glass fiber reinforced plastic has always maintained the smooth surface of the new tube.

4. Process FRP pipe installation and maintenance costs are low. Generally speaking, FRP pipe does not require special anti-corrosion treatment; the insulation layer can be thinned, or even no additional insulation treatment; the pipeline is relatively light, the lifting equipment is small in tonnage, and the power consumption is low. The length of FRP pipes is longer than that of cement pipes and cast iron pipes, and the joints are relatively reduced, which will reduce installation and maintenance costs. This has been proved by many engineering practices at home and abroad.

5. The design flexibility of process FRP pipes is large, and the modification period is short. FRP is made of fiber reinforced material impregnated with a resin matrix, wound layer by layer on a core mold according to specific process conditions and properly cured. The tube wall is a layered structure, which can be changed by changing the resin system or using different Reinforcement materials are used to adjust various physical and chemical properties of FRP pipes to adapt to different media and working conditions to make FRP pipes with different pressure levels or with certain special properties. The short modification period is a remarkable feature of fiber-wound composite materials, which cannot be compared with isotropic metal pipes.
