Introduction: Storage tanks are used to store refined chemical substances such as acids, bases, alcohols, gases, and liquids. Storage tanks are widely used in North China, including rotational plastic tanks, fiberglass tanks, ceramic tanks, rubber tanks, welded plastic tanks, etc. In terms of cost-effectiveness of storage tanks, fiberglass storage tanks are currently the most popular. They have excellent corrosion resistance, high strength, long service life, and can be manufactured in various forms such as vertical, horizontal, transportation, and mixing.
　　
With the eyesTank industryWith the continuous development, more and more industries and enterprises are using storage tanks, and more and more enterprises are entering the storage tank industry. Steel storage tanks are equipment for storing various liquid (or gas) raw materials and finished products. For many enterprises, normal production cannot be achieved without storage tanks, especially for national strategic material reserves, which cannot do without various capacities and types of storage tanks. Our country's oil storage facilities are mainly composed of above ground storage tanks, and are mostly made of metal structures.
　　
The product performance of PE plastic storage tanks is that the plastic used in PE plastic storage tanks has a minimum softening point of 108 ℃ and a maximum fragmentation point of -70 ℃, so it can generally be used to hold liquids with temperatures ranging from -40 ℃ to 60 ℃. If the liquid density is heavy or the temperature is higher than 60 ℃, a steel lined plastic anti-corrosion storage tank should be used to prevent softening and deformation of the PE plastic storage tank. If PE plastic storage tanks are used for chemical reactions or dilutions, corresponding tests should be conducted in advance to determine the highest temperature for the reaction or dilution.

2. The material of PE plastic storage tanks produced by Haiqiang Company is rolled plastic - linear low-density polyethylene (LLDPE) or linear medium density polyethylene (LMDPE). PE plastic storage tanks can hold inorganic acids, alkalis, salts, and many organic substances at room temperature.
　　
3. The plastic used in PE plastic storage tanks has a minimum softening point of 108 ℃ and a maximum fragmentation point of -70 ℃, so it can generally be used to hold liquids with temperatures ranging from -40 ℃ to 60 ℃. If the liquid content is heavy or the temperature is above 60 ℃, a steel lined plastic anti-corrosion storage tank should be used to prevent softening and deformation of the tank. If PE plastic storage tanks are used for chemical reactions or dilutions, corresponding tests should be conducted in advance to determine the highest temperature for the reaction or dilution.
　　
4. The joints on PE plastic storage tanks should be equipped with acid and alkali resistant gaskets when containing acidic and alkaline substances. When storing organic matter (especially organic solvents), prepare insoluble rubber gaskets.
　　
5. PE plastic storage tank products are not suitable for containing strong oxidants (such as sulfuric acid with a concentration of over 75% and concentrated nitric acid with a concentration of over 30% at a temperature of 60 ℃) and good organic solvents (benzene, ether, ketone, ester).
　　
Steel sealed containers used for storing liquids or gases are called steel storage tanks. Steel storage tank engineering is an important infrastructure in industries such as petroleum, chemical, grain and oil, food, fire protection, transportation, metallurgy, and national defense. Our economic life always relies on steel storage tanks of all sizes. The important role of steel storage tanks in the development of the national economy is crucial.
