PPH storage tank It is a new type of polypropylene tank. The processing method is also different from the old welding process. PPH storage tank is formed by extrusion and winding at one time. Carefully check the PPH tank before use.

The PH storage tank shall be visually inspected before use, and its surface shall be free of cracks, shrinkage cavities, slag inclusion, folding, skinning and other defects. The corrosion depth and concave mechanical damage depth shall not exceed the negative wall thickness deviation allowed by the corresponding product standard.

The shell test pressure of PPH tank valve shall be less than 1.5 times of the nominal pressure, and the test time shall be less than 5min. The enclosure packing is qualified if there is no leakage. The sealing test shall be conducted under the nominal pressure, and the sealing surface of the valve shall be free of leakage. It is qualified.

For the pipeline gate valve of mechanical equipment conveying dangerous liquids and flammable liquids, the design method is that the working pressure is greater than 1MPa, and the design method is that the temperature is less than - 29 ℃ or greater than 186 ℃. For non flammable liquids, the working pressure test of the pipeline gate valve shell with dangerous liquids is carried out. And sealing test.

Please observe PPH mixing tank The protruding surface of the external thread, together with the accuracy and surface roughness, shall conform to the design concept or specification, and shall be provided with commodity identification.

PPH storage is mainly used for the storage and storage of chemical enterprises such as pharmaceutical factories and pesticide factories, as well as raw materials in the production and processing of petroleum, medicine, food industry, vegetable oil, paper making, steel industry, ecological environment, etc. Protection, industry and other processing and manufacturing industries.
