Vertical carbon steel storage tank is a closed or semi closed container made of carbon steel as raw material and designed with a vertical structure. Its core advantages include low cost, strong bearing pressure, mature manufacturing technology, and adaptability to large volume storage needs (ranging from tens of cubic meters to thousands of cubic meters). It can meet the storage needs of liquid and solid particles at "normal temperature, normal pressure or medium low pressure". Therefore, it is widely used in multiple industries that require "storage safety, economy, and easy maintenance". The following provides a detailed analysis of core application industries and typical scenarios:
1、 Petrochemical industry: Core storage of "flammable, explosive/low corrosive media"
Petrochemical industry is the application field of vertical carbon steel storage tanks, mainly used for storing crude oil, refined oil, chemical raw materials, etc. It needs to meet the requirements of "explosion prevention, leakage prevention, and easy loading and unloading", and the carbon steel material can adapt to most non corrosive media:
Storage of crude oil and refined oil products:
Refinery: Vertical carbon steel storage tanks with a capacity of 100-5000m 3 are used to store crude oil (incoming raw materials), gasoline, diesel, and kerosene (finished products). The tank walls are mostly made of "Q235-B carbon steel" (resistant to room temperature, impact, and low cost), and the top of the tank is equipped with a breathing valve (to balance the pressure inside the tank and prevent overpressure or negative pressure), lightning rods (explosion-proof), and a drain outlet at the bottom of the tank (to clean sedimentary impurities);
Gas stations/oil depots: Small vertical carbon steel storage tanks with a capacity of 50-200m 3 are used to store gasoline and diesel, usually buried underground or outdoors. The tank walls are coated with anti-corrosion materials (such as epoxy coal tar) to prevent soil corrosion or rainwater erosion.
Chemical raw material storage:
Store "weakly corrosive/neutral chemical media" such as methanol, ethanol, ethylene glycol, lubricating oil, paraffin, etc. (strong corrosive media such as hydrochloric acid and sulfuric acid require stainless steel or fiberglass storage tanks);
Vertical carbon steel storage tanks with a capacity of 100-1000m 3 are commonly used in chemical plants. The tank can be coated with an "internal anti-corrosion coating" (such as polytetrafluoroethylene coating) to improve its tolerance to slightly corrosive media. A liquid level gauge (real-time monitoring of storage capacity) and feed/discharge pipelines (adapted for pump body loading and unloading) are installed on the top of the tank.
2、 Energy industry: adapting to large-scale storage of "fuel/energy media"
The energy industry needs to store energy media with "large volume, room temperature, and low corrosion" (such as coal, biomass fuel, and thermal oil). The "large volume, high load capacity" characteristics of vertical carbon steel storage tanks can meet the demand:
Coal and solid fuel storage:
Thermal power plants and coal chemical enterprises: Use vertical carbon steel storage tanks with a capacity of 500-2000m 3 (often "open type", with a rain shelter at the top) to store coal powder, coal slag, and biomass particles (such as sawdust and straw pellets). The tank walls are made of thick walled carbon steel (≥ 8mm), which can withstand the lateral pressure of solid particles. The tank bottom is equipped with a discharge port (matched with a screw conveyor for easy transportation to boilers or production lines);
Advantages: Compared to traditional silos, vertical carbon steel storage tanks have a smaller footprint and larger storage capacity. Additionally, carbon steel is wear-resistant and not easily worn by long-term contact with solid particles.
Thermal oil/heat transfer medium storage:
New energy power plants (such as thermal systems for photovoltaic and wind power), large factories: Use vertical carbon steel storage tanks with a capacity of 50-500 cubic meters to store heat transfer oil (for heat transfer), with an "external insulation layer" (such as rock wool+color steel plate) on the tank wall to prevent heat loss. The tank is equipped with heating coils (to prevent heat transfer oil from solidifying in winter), suitable for "medium and low temperature (≤ 300 ℃)" storage needs (stainless steel storage tanks are required for high temperature).
3、 Water treatment and environmental protection industry: storage and treatment of "water/sewage/chemicals"
The water treatment and environmental protection industry requires the storage of "large amounts of water bodies, sewage or water treatment agents". The "easy to clean and customizable" characteristics of vertical carbon steel storage tanks are suitable for this scenario, and the corrosion resistance of carbon steel to water can be improved through anti-corrosion treatment:
Raw water/clean water storage:
Waterworks and sewage treatment plants: 1000-5000m 3 vertical carbon steel storage tanks (often "open top+floating roof" to reduce water pollution) are used to store raw water (river water and groundwater to be treated) and clean water (treated standard water). The tank walls are coated with "epoxy resin" (to prevent rusting of carbon steel and pollution of water quality), and a guide groove is installed at the bottom of the tank (to facilitate uniform water discharge);
Industrial park: Use 200-1000m 3 vertical carbon steel storage tanks to store circulating water (for the factory cooling system), with ventilation openings on the top of the tanks (to maintain oxygen content in the water and prevent algae growth).
Sewage/sludge storage:
Sewage treatment plant: Use vertical carbon steel storage tanks with a capacity of 500-2000m 3 to store "pre treated sewage" (to be sent to the biochemical treatment system) and "dehydrated sludge" (to be transported and disposed of). The tank walls are coated with "internal anti-corrosion+wear-resistant coating" (the sewage contains a small amount of acid and alkali, and the sludge has abrasion resistance), and a mixing device is installed at the bottom of the tank to prevent sludge deposition;
Landfill site: Vertical carbon steel storage tanks with a capacity of 100-500m 3 are used to store "leachate" (sewage leaked from garbage needs to be pre treated and transported to the sewage treatment plant). The tank walls are thickened (≥ 10mm) and reinforced with ribs to withstand the weight and slight corrosiveness of the leachate.
Storage of water treatment agents:
Store "neutral/weakly alkaline agents" such as polyaluminum chloride (PAC), polyacrylamide (PAM), sodium hypochlorite (low concentration), etc. in a 50-200m 3 vertical carbon steel storage tank with anti-corrosion coating inside and a stirrer on the top of the tank (to maintain the uniformity of the agents and prevent precipitation).
4、 Food and Brewing Industry: Storage of "Non Acidic/Low Corrosion Food Ingredients"
The food industry has requirements for the "hygiene" of storage tanks. Vertical carbon steel storage tanks need to undergo "food grade anti-corrosion treatment" and be suitable for storage of "normal temperature, non acidic food raw materials" (acidic raw materials such as vinegar and juice need to be stored in stainless steel tanks):
Edible oil/fat storage:
Edible oil processing plants and grain and oil enterprises: Use 100-1000m 3 vertical carbon steel storage tanks to store soybean oil, rapeseed oil, and palm oil (which are liquid or semi-solid at room temperature). The tanks are coated with "food grade epoxy resin" (in accordance with GB 4806.10-2016 food contact standards), and inert gas protection devices (such as nitrogen to prevent oil oxidation and deterioration) are installed on the top of the tanks. Heating coils are installed at the bottom of the tanks (to melt semi-solid oils and fats in winter for easy discharge).
Raw material storage in the brewing industry:
Distillery and soy sauce factory: Use vertical carbon steel storage tanks with a capacity of 50-500 cubic meters to store "brewing water" (such as underground water and purified water from the distillery) and "grain raw materials (such as crushed sorghum and wheat)" (open storage tanks with rain shelters). The tank walls are made of food grade anti-corrosion to prevent metal ions from precipitating and contaminating the raw materials;
Attention: Fermented alcoholic beverages, soy sauce, and other media containing acidic or organic substances should be stored in stainless steel tanks to avoid corrosion of carbon steel.
5、 Metallurgical and Machinery Manufacturing Industry: Storage of "Industrial Auxiliary Materials/Waste Liquids"
The metallurgical and mechanical manufacturing industries require the storage of media such as coolant, lubricating oil, and waste oil. The "wear-resistant and easy to maintain" characteristics of vertical carbon steel storage tanks are suitable for the industrial environment of this scenario
Coolant/lubricant storage:
Steel plants and machine tool factories: Use 50-200m 3 vertical carbon steel storage tanks to store "emulsion" (coolant for metal cutting) and "mechanical lubricating oil" (for equipment lubrication). The tank walls are coated with "anti rust coating" (the workshop environment is dusty and oily, preventing carbon steel from rusting), and the tank bottom is equipped with a filtering device (to filter impurities and ensure the purity of coolant/lubricating oil).
Waste oil/liquid storage:
Mechanical factories and automobile repair shops: Use small vertical carbon steel storage tanks of 20-100m 3 to store "waste engine oil" (to be recycled) and "cleaning waste liquid" (such as oily wastewater after parts cleaning, which is pre treated and transported to the environmental protection department). The tank walls are coated with anti-corrosion to prevent waste liquid corrosion, and the tank top is equipped with a sealing cover to prevent odor diffusion.
6、 Construction and Building Materials Industry: Storage of "Building Materials/Construction Accessories"
The construction and building materials industry requires the storage of "large quantities, room temperature, and non corrosive" solid or liquid building materials. The "large volume, high stability" of vertical carbon steel storage tanks can improve storage efficiency:
Storage of cement/dry powder building materials:
Cement plants and construction sites: Use 100-1000m 3 vertical carbon steel storage tanks (open type, with dust covers) to store cement, dry powder mortar, putty powder, etc. The tank walls are made of thick walled carbon steel (≥ 10mm), which can withstand the lateral pressure of dry powder. A screw conveyor is installed at the bottom of the tank (directly transported to the mixer to reduce manual handling);
Advantages: Compared to traditional cement silos, carbon steel storage tanks have better sealing, reduce dust leakage, and have a longer service life (up to 10-20 years).
Storage of Coatings/Adhesives:
Building materials factory: Use 50-200m 3 vertical carbon steel storage tanks to store "water-based coatings" (such as wall paint, waterproof coatings, neutral or weak alkaline) and "building adhesives" (such as epoxy resin adhesive, stored at room temperature). Apply an "internal anti-corrosion coating" inside the tank (to prevent slight corrosion of solvents in the coating), and install a mixer on the top of the tank (to maintain uniform coating and prevent sedimentation).
