Before using a carbon steel storage tank, please inspect it carefully in order to better ensure that it can serve you.

       1, Appearance inspection should be carried out before use. The surface should be free of defects such as cracks, shrinkage holes, slag inclusions, folds, and heavy skin. The depth of corrosion, dents and other mechanical damage must not exceed the negative deviation of wall thickness allowed by the corresponding product standard.

       2,carbon steel storage tankThe shell test pressure of the valve shall not be less than the nominal pressure1.5times, the test time shall not be less than5min, the shell packing is qualified if there is no leakage, the sealing test is conducted at nominal pressure, and the valve disc sealing surface is qualified if there is no leakage.

       3, when the equipment transports harmful fluids and flammable fluid pipeline valves, the transport design pressure is greater than1Mpa, and the design temperature is less than-29℃or greater than186℃The valves of non-combustible fluids and harmless fluid pipelines shall be subjected to shell pressure tests and sealing tests one by one.

       4, please carefully observe the thread sealing surface, groove accuracy and roughness of the carbon steel storage tank. The accuracy and roughness should meet the design requirements or manufacturing standards, and there should also be product identification.
