Bolted tank vs welded tank for small internal pressures

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 Bolted tank vs welded tank 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.

Generally, external environment corrosion should be considered before design and construction of Bolted tank vs welded tank and so on storage tanks. The corrosion on the outer surface of storage tank is often worse than that on the inner surface. Especially in the chemical industry area, there are often acid fog, alkali or salt dust in the atmosphere. These impurities form an active corrosive medium with dew or steam and oxygen in the atmosphere. The corrosion of the external environment of the storage tank shortens the maintenance period of the storage tank, even causes the storage tank to be scrapped in advance, which affects the normal operation of the storage and transportation.

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of Bolted tank vs welded tank service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

Compared with the fixed roof API 650 oil storage tank without Bolted tank vs welded tank 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 Bolted tank vs welded tank product and pollutes the environment.
