Fiberglass reinforced plastic(FRP) tanks have the characteristics of light weight, corrosion resistance, low maintenance costs, long service life, low cost and convenient installation. This article aims to prevent damage as much as possible and maximize its service life.

1.Restrictions on the use of fiberglass storage tanks

• The use of fiberglass storage tanks is limited to the design conditions, and the medium (including medium concentration), temperature, pressure, etc. cannot be changed arbitrarily.
• Fiberglass storage tanks refer to hydrostatic tanks that are connected to the atmosphere, especially vertical flat bottomed tanks. They should ensure that the tank body is unobstructed and in good condition with the atmosphere, and will not be pressurized (positive or negative) due to venting, feeding, or temperature changes. The maximum working pressure of pressure storage tanks (containers, towers) is not allowed to exceed the design specified value. Unless specially designed, the vibration source (mixing, recoil device), cold and hot pipes, should be isolated and supported from the tank body.
• Fiberglass storage tanks cannot be loaded on the top of the tank at will. It is strictly prohibited to use negative pressure in atmospheric storage tanks!
• Fiberglass storage tanks cannot be loaded during connection, and effective vibration avoidance facilities should be installed for connections with vibration sources.
• Fiberglass storage tanks should not be near fire or away from heat sources.

2.Tank maintenance of fiberglass storage tanks

• When entering the fiberglass acid-base tank for maintenance, all feeding valves should be closed first, and the tank body should be emptied and cleaned. After testing and confirming that there are no toxic gases in the tank and there is no oxygen deficiency, the tank can only be entered. When entering the tank, soft soled shoes should be worn, safety belts should be tied, and the other end of the safety belt should be tied to the top of the tank. Attention should be paid to the ventilation inside the tank. Entering the tank for operation must be carried out by personnel under external monitoring.
• To prevent tools from colliding with the tank wall, soft pads should be added to the contact parts of the tank wall when using ladders and metal parts to protect the inner wall from scratches and bruises.
• The external ladder, protective cage, and guardrail of fiberglass storage tanks should be carefully checked for safety and reliability before climbing. It is strictly prohibited to climb and use them if there are any abnormalities.
• When repairing fiberglass storage tanks, it is not allowed to load them randomly on the top of the tank or apply external forces on the connecting pipes.
• After years of outdoor use, fiberglass storage tanks may experience resin layer peeling or fiber exposure due to aging of the outer layer. It is recommended to apply paint or resin to the outer surface of the tank every two or three years to prevent aging and extend its service life.
