FRP tanks

FRP tank is a non-metal composite tank in which resin and glass fiber are wound by a computer controlled machine. It has the advantages of corrosion resistance, high strength, long life, flexibility in design, and manufacturability. According to the characteristics of FRP tanks, FRP tanks are widely used in chemical, environmental protection, food, pharmaceutical, printing and dyeing and other fields, gradually replacing carbon steel and stainless steel in most mayor/market fields.

The status quo of the FRP tank industry:


(1) Good mechanical and physical functions


The data density of FRP is generally 1.2 ~ 1.9G/CM3, which is about 1/5 ~ 1/4 of steel. It has stronger strength and better physical function than steel, cast iron, plastic, etc., and the thermal expansion coefficient is roughly equivalent to steel. A thermal conductivity of as little as 0.5% of steel is a suitable good thermal and electrical insulator.


(2) chemical corrosion resistance


When transporting or storing corrosive media, FRP has a special refractory basic function that is several times longer than ordinary steel pipes, dozens of times or even much longer than stainless steel. However, the anti-corrosion function of FRP pipes and FRP tanks has a lot to do with basic materials, humectants, medium properties, use conditions, wall thickness structure and temperature. For the detailed media and operating conditions, only the correct choice of raw materials and structures can achieve the desired anti-corrosion effect.


(3) Excellent hydraulic properties


Hydraulic characteristics are one of the main characteristics of pipelines. Excellent hydraulic characteristics mean that the fluid head loss is small. You can choose a transport pump with a small pipeline diameter or a small power, and then reduce the initial investment in pipeline engineering, save electricity, and reduce working capital. The inner appearance of the FRP pipe is properly lubricated, which can be said to be a "hydraulic lubricating pipe". During operation, the internal appearance of steel pipes, cast iron pipes, cement pipes, etc. is often partially corroded and becomes more and more rough, while FRP pipes always keep the appearance of new pipes in a lubricated state.

(4) Low equipment maintenance cost


FRP tanks do not require special anti-corrosion treatment, the insulation layer is thinned or does not require insulation treatment. The pipeline is light, the lift is simple, and the power consumption is small, which can simplify the support structure or base. The length of glass steel pipe is longer than that of steel pipe, and the joints are relatively reduced.
