API 650 floating-roof tanks lap-welded bottom joints

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API 650 floating-roof tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.

Facilities for API 620 Storage Tanks InspectorThe manufacturer shall afford the inspector all reasonable facilities for testing and inspection and shall provide mutually agreeable advance notification to permit the examiner to witness all tests of the equipment and materials during fabrication, including all laboratory tests of the material to be used and all hydrostatic and pneumatic tests at the site of erection.The API 650 floating-roof tanks inspector shall be permitted free access to all parts of the plant concerned with the manufacture of the tank during fabrication and to all parts of the plants of material suppliers who are concerned with the manufacture of materials to be used in the tank.

API 650 floating-roof tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API 650 floating-roof tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API 650 floating-roof tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API 650 floating-roof tanks?
