SF buried double-layer oil tank design and manufacturing requirements

1. The design and manufacture of SF double-layer oil tank should follow the requirements of pressure vessel technical specifications and relevant standards.

2. The SF double-layer oil tank should be able to meet continuous operation for more than 30 years, and the related performance (operation and sealing) of the oil tank can meet the requirements of working conditions for a long time.

3. The SF double-layer oil tank is composed of an inner tank and an outer tank. The inner tank of the tank is a steel shell, and the outer tank of the tank is a glass fiber reinforced plastic shell; the outer tank should completely contain the inner tank .

4. The SF double-layer oil tank should be equipped with a vent pipe, the vent pipe mouth should be equipped with a flame arrester, and the nominal diameter of the pressure vessel vent pipe should not be less than 50mm. 5. The SF double-layer oil tank should be equipped with no less than two steel lifting lugs, and the total lifting capacity of the lifting lugs should not be less than 2 times the dead weight of the tank.

6. The SF double-layer oil tank has a penetration gap of 0.1~3.5mm between the inner and outer tank bodies, and is equipped with a leak detector connected to it, which can monitor the inner and outer tanks of the pressure vessel for leaks in real time. Double-layer oil The manufacturer of the tank shall provide the instruments used for the leak detection system of the double-layer oil tank.

7. The production enterprise shall test the volume and penetration of the protected space. The volume of the space shall be between 2L and 20L/(volume of oil storage tank per m3) (excluding the volume of non-protected space such as test riser).
