Precautions for the use of polyethylene storage tanks

If there is a joint or flange connecting pipe at the bottom of the storage tank, it should be perpendicular to the barrel wall and a soft connection should be used to prevent uneven expansion of the barrel wall after filling with liquid, which may cause damage to the joint connection and leakage, and in severe cases, damage to the joint and barrel body.

2. The receiving equipment should use acid resistant gaskets and seal them, and the gaskets should be replaced in a timely manner.

To prevent damage to the equipment under pressure, it is necessary to open the air interface for filling and outputting the equipment.

4. Anti static equipment should be provided to store high resistance organic solvents.

.

5. The operating environment of the equipment should be kept away from the earthquake source and avoid contact with open flames.

When storing chemicals in polyethylene anti-corrosion storage tanks, the stored items should be clearly labeled. Good drainage channels and dilution equipment should be provided around the location of the polyethylene anti-corrosion storage tank.

7. Due to the fact that the raw material of all plastic flanges is softer than steel plates, users should check the sealing function of the polyethylene anti-corrosion storage tank equipment before use and add liquid to investigate for leaks. Perform leak testing on storage tanks containing chemical liquids using water to prevent component loss.

During transportation and equipment, polyethylene anti-corrosion storage tanks should be protected from severe impacts and collisions on the equipment body.

Horizontal polyethylene anti-corrosion storage tanks should be placed on a base made of cement bricks. The foundation is generally made by on-site stacking method, which means placing the horizontal tank at the application address and filling it with brick cement. Pay attention to placing some sand on the contact surface between the tank body and the brick, and wait for the root and bottom of the cement brick to fully solidify before putting it into use. The height of the base is usually half of the height of the water tank.

Vertical polyethylene anti-corrosion storage tanks can be placed flat on the ground before installation. The foundation of the polyethylene anti-corrosion storage tank for the equipment needs to be laid flat on the ground and able to withstand the corresponding pressure. Due to the inability to prevent the bottom of large vertical polyethylene anti-corrosion storage tanks from protruding into the tank and forming a spherical crown during molding, it is advocated that the corresponding spherical crown at the bottom of the tank should be laid with 2-6cm of fine sand on a horizontal foundation.
