Classification and application of stainless steel storage tanks, precautions for use

1. Classification of stainless steel storage tanks 1. Classification by form: can be divided into vertical stainless steel tanks, horizontal stainless steel tanks. 2 Classification by use: can be divided into wine stainless steel tanks, food stainless steel tanks, pharmaceutical stainless steel tanks, dairy products Stainless steel tanks, chemical stainless steel tanks, petroleum stainless steel tanks, building materials stainless steel tanks, electric power stainless steel tanks, metallurgical stainless steel tanks. 3 Classification according to hygienic standards: sanitary stainless steel tanks, ordinary stainless steel tanks. 4 Classification according to pressure requirements: stainless steel Pressure vessels, non-stainless steel pressure vessels. 2. Common stainless steel storage tanks Stainless steel storage tanks, stainless steel pressure tanks, stainless steel wine tanks, stainless steel milk tanks, stainless steel reaction tanks, stainless steel vacuum tanks, stainless steel fermentation tanks 3. Overview of stainless steel storage tanks 1. Food Pharmaceutical stainless steel storage tanks: stainless steel ingredients storage tanks, stainless steel concentrated storage tanks, stainless steel dilute storage tanks, stainless steel extraction storage tanks, stainless steel reaction storage tanks, stainless steel liquid storage tanks, stainless steel mixing tanks, stainless steel seed storage tanks, stainless steel nitric acid storage tanks Tanks, stainless steel glacial acetic acid storage tanks, stainless steel carbon disulfide barrels, stainless steel water tower storage tanks. 2. Stainless steel tanks for brewing and dairy industry: stainless steel wine storage tanks, stainless steel liquor storage tanks, stainless steel wine storage tanks, stainless steel milk (milk) tanks, stainless steel beverage storage tanks 3. Chemical stainless steel tanks: stainless steel oil storage tanks, stainless steel transportation storage tanks , Stainless steel cooling storage tanks, stainless steel insulation storage tanks, stainless steel heat exchange storage tanks, stainless steel buffer tanks, stainless steel outdoor storage tanks and various levels of stainless steel pressure vessels in the chemical industry. 4. Features of stainless steel storage tanks: 1. Stainless steel tanks have strong corrosion resistance, and they are not corroded by external air and residual chlorine in water.

Each spherical tank has undergone a super pressure test and inspection before leaving the factory, and its service life can reach more than 100 years under normal pressure. 2. The stainless steel tank has good sealing performance; the sealed design completely prevents harmful substances in the air dust and mosquitoes from invading the tank, ensuring that the water quality is free from external pollution and breeding of red worms. 3. The scientific water flow design prevents the sediment at the bottom of the tank from turning up due to the water flow, ensuring the natural stratification of domestic water and fire-fighting water. The turbidity of domestic water coming out of the tank is reduced by 48.5%; but the water pressure is significantly increased. .

It is beneficial to improve the performance of domestic water and fire water facilities. 4. The stainless steel tank does not need to be cleaned frequently; the sediment in the water can be discharged only by regularly opening the drain valve at the bottom of the tank. Simple equipment can be used to remove scale once every 3 years, greatly reducing cleaning costs and completely avoiding human bacterial and virus contamination.

Five. The use of stainless steel storage tanks 1. Stainless steel storage tanks are storage tanks made of stainless steel as raw materials. Compared with ordinary rotomolded storage tanks, stainless steel storage tanks can withstand higher pressures and are widely used in many high-pressure situations. At the same time, stainless steel storage tanks have a very remarkable feature: the tank body has excellent sealing performance, completely eliminating air pollution. The intrusion of harmful substances and mosquitoes ensures that the liquid stored in the tank will not be polluted by the outside world and will not breed red worms. Therefore, stainless steel storage tanks are mostly used to store and transport food and medicine, and are widely used in winemaking and dairy industries. Matters needing attention (1) The fire and explosion protection of oil storage tanks and storage tank areas shall comply with the provisions of GB50183 and GB50074.

The low-expansion air foam fire extinguishing system shall comply with the provisions of GB50151. (2) The storage tank area should be kept clean, and there should be no hay, no oil, and no combustibles in the fire dike. (3) Water-sealed wells should be installed in the drainage system of the storage tank area; valves should be installed outside the fire embankment for the drainage pipes; when the oil tank is drained, special personnel should monitor and remove the residual oil in the water-sealed wells in time.

(4) Non-explosion-proof electrical equipment and high-voltage overhead lines should not be installed in the storage tank area. (5) Fire dikes shall be set up in the storage tank area according to the regulations, and the fire dikes shall be kept intact. (6) The top of the oil storage tank should be free from oil and water.

Heat preservation measures should be taken for the oil inlet and outlet pipelines and valves of the oil storage tank. (7) The light transmission hole, gauge hole cover and gasket on the top of the oil storage tank should be kept intact, and the hole cover should be tightly closed. The dipstick should be fitted with a non-sparking metal gasket.

(8) The breather valve on the oil storage tank and the base of the hydraulic safety valve should be equipped with a flame arrester. Flame arresters are inspected at least once a quarter. (9) Flexible hose compensators should be installed on the inlet and outlet pipelines of oil storage tanks.

(10) The steel oil storage tank body should be equipped with lightning protection and anti-static grounding device, and its grounding resistance should not be greater than 10Ω. The grounding point shall be set at least one point every 30m along the bottom edge of the tank, and the grounding point of a single tank shall not be less than two. (11) The lightning protection and anti-static grounding device should be fully inspected every spring, and the grounding resistance value should meet the requirements.

(12) Two annealed copper wires with a cross-sectional area of ​​not less than 25mm2 shall be used to connect the pontoon and the tank wall of the floating roof tank. (13) The oil volume of the oil storage tank should be operated within the safe tank position. (14) When the condensate oil level is higher than the heating coil, it should be heated with a steam riser first, and then heated with a steam coil after the condensate is melted.

(15) Chemical fiber clothing and shoes with nails should not be worn. Non-explosion-proof flashlights should not be turned on and off on the top of the tank. (16) Industry regulations shall be followed for oil pipeline fire and tank cleaning operations in the storage tank area.

(17) If the oil storage tank is on fire, it should be reported immediately and all operations on the fire oil tank should be stopped.
