API 5L grade B pipe API standard 650 SUG III tanks
API 620 Crude Oil Tank Pneumatic PressureAn 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 standard 650 SUG III tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.
The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API standard 650 SUG III tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
The Egypt customer ordered 130 tons API standard 650 SUG III tanks stainless steel plate in stock, and this batch has left port today for its destination today(October 25th, 2019). 316l stainless steel is molybdenum-bearing austenitic stainless steel. This material has better corrosion resistant property than 304/314L for it's higher Ni and Mo content. (it is considered to be marine grade stainless steel, not suitable for warm sea water treatment). 316L austenitic stainless steel supplied by our company has good formability and weldablity, additionally it is proved to have excellent properties of tensile, creep and stress-rupture strengths in elevated temperature environment.
}High temperature heat transfer oil fin tube heating device for large API standard 650 SUG III tanks has the advantage of reducing the leakage of heating coils. The heating medium of the large storage tank heating device is high-temperature heat-conducting oil. The boiling point of the heat-conducting oil is high, usually higher than 200°C. At high temperatures, the pressure on the heat-conducting oil circulation pipeline is very small, which greatly reduces the occurrence of heating coil leakage accidents. At the same time, the temperature difference between the inside and outside of the tube is guaranteed.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
