Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API Std 650 SUG I tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.
Compared with the fixed roof API 650 oil storage tank without API Std 650 SUG I tanks floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API Std 650 SUG I tanks product and pollutes the environment.
The Egypt customer ordered 130 tons API Std 650 SUG I 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.
