ASTM A27 grade 60-30 floating roofs API Std 650 SUG III tanks

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API Std 650 SUG III tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.

If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API Std 650 SUG III tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.

With the fast development in Myanmar, Myanmar navy build frigate every year. Bebon Cooperate with Myanmar Navy from from 2015. They purchased 412 ton API Std 650 SUG III tanks LR AH36 steel plate from Bebon as trial order in 2015. After receiving the goods, they speak highly of the quality and bebon's service. After that they purchase the shipbuilding steel plate from bebon regularly. In May,2018, the Myanmar navy's local representative visit our office and production line, and sign another contract 2025 tons API Std 650 SUG III tanks LR A shipbuilding steel plates order in our office.

Generally, the building area temperature of the API Std 650 SUG III tanks should be considered before the tank design and construction. The temperature in the API Std 650 SUG III tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API Std 650 SUG III tanks, the higher the corresponding pressure and the more volatile loss.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
