because PPH winding tank It has excellent corrosion resistance, especially environmental stress cracking resistance, so it will not react with dilute or concentrated solutions of inorganic salt water solution, inorganic acid and alkali even at high temperatures. Chemical reaction. At present, PPH winding tank plays an important role in our daily life. Whether it is an essential basic equipment in petroleum, chemical industry, grain and oil, food, fire protection, transportation, metallurgy, national defense and other industries, the exhaust hole plays an important role in use. How should the exhaust hole be installed?
When PPH winding tank adopts medium inlet and outlet flow, exhaust holes with corresponding flow shall be installed. When changing the liquid content, you should know whether the tank is allowed to hold liquid. If there is a joint or flange pipe at the lower part of the tank, it should be perpendicular to the barrel wall, and soft connection should be used to avoid uneven expansion of the barrel wall from top to bottom after liquid injection, which will lead to damage and leakage of the joint connection. When the liquid inlet is higher from the tank bottom, the liquid inlet shall bend towards the tank wall to make the incoming liquid fall along the tank wall and reduce the impact on the bottom. The hydraulic pressure shall be stored firmly and strengthened when connected with other flanges. Common flange and PPH storage tank They are generally tightened when leaving the factory, which may cause looseness during transportation and loading and unloading. The user should check the sealing performance of the roto plastic storage tank before use, and add liquid to observe whether there is leakage.
