I. Product Overview
The carbon steel storage tank is a large-capacity material storage container made from high-quality carbon structural steel plates through multiple precise processes such as professional cutting, rolling and welding, forming and reinforcement, anti-corrosion treatment, and pressure testing. It is a widely used general-purpose storage device in industrial production and material storage and transportation fields. The product features strong pressure-bearing capacity, stable structure, economic cost, and wide application range. It can be customized in various specifications such as vertical, horizontal, atmospheric pressure, pressure-bearing, and anti-corrosion according to different usage scenarios, storage media, and capacity requirements, and perfectly adapts to the long-term sealed storage of various industrial liquids, chemical raw materials, oil products, water media, etc. It is the core storage and transportation equipment for industrial enterprises, chemical parks, oil depots, water treatment plants, and other places. 
II. Product Classification 
(1) Arrangement by structural form 
Vertical carbon steel storage tank
It adopts a vertical cylindrical structure, with a small floor area, high storage space utilization rate, stable center of gravity, facilitating on-site installation and later pipeline connection. It is suitable for fixed positions in the factory and large-capacity material storage, and is the mainstream selection in the industry. 
2. Horizontal carbon steel storage tank
The horizontal cylindrical design features a low center of gravity and excellent stability, with superior pressure resistance. It is convenient for short-distance transportation and mobile installation, and is suitable for scenarios with small capacity, high pressure conditions, and limited space. 
(2) According to usage function and process 
Pressure-resistant carbon steel storage tank
Suitable for the storage of conventional materials under normal temperature and pressure conditions. It has a simple structure and high cost-effectiveness, meeting the basic storage needs for most neutral media, water, and oil products. 
2. Pressure-bearing carbon steel storage tank
Designed and manufactured in accordance with national standards, it features excellent pressure resistance and sealing performance. It can withstand certain pressure and is suitable for storing chemical media, gases, and volatile materials with pressure requirements. It has a high safety factor. 
3. Anti-corrosion carbon steel storage tank
The interior of the tank is treated with professional anti-corrosion coatings (such as epoxy coal tar asphalt, fiberglass reinforced plastic, plastic lining, etc.), and the exterior is coated with anti-rust and anti-corrosion paint to effectively resist the erosion of acids, alkalis and corrosive media, thereby extending the service life of the equipment. 
4. Insulated carbon steel storage tank
The tank body is equipped with an insulation layer and a protective shell, enabling the storage of materials at a constant temperature. This prevents the materials from solidifying, deteriorating, or evaporating due to temperature changes. It is suitable for oil products, chemical raw materials, and special fluid media that require temperature control.

IV. Core Product Advantages 
1. The material is sturdy and has strong pressure-bearing capacity.
The tank is made of high-quality carbon steel that meets national standards. It has high density, high tensile strength, and excellent toughness. The tank body is firmly welded and the structural mechanical design is reasonable. It has outstanding pressure-bearing, impact resistance, and deformation resistance capabilities, and can adapt to complex industrial environments. It is unlikely to deform or crack over a long period of use. 
2. Excellent cost-performance ratio, controllable costs
Compared with stainless steel and special alloy storage tanks, carbon steel has a lower raw material cost, and the overall equipment cost is more economical. Moreover, the processing technology is mature, the production cycle is short, the initial investment is low, and the later maintenance is simple, significantly reducing the equipment procurement and operation costs of enterprises. 
3. Excellent sealing performance, safe and reliable
Using fully automatic welding technology, the weld seams undergo dual inspections including non-destructive testing, water pressure test and air tightness test to eliminate leakage and seepage problems; the fully sealed structure effectively prevents material evaporation and leakage, isolates external impurities from contaminating, and ensures the safety of material storage. 
4. High degree of customization and strong adaptability
Based on the attributes of the storage medium, storage capacity, installation site, working pressure, and anti-corrosion requirements, etc., the tank body specifications, structure, anti-corrosion process, and accessory configuration can be flexibly customized to fully meet the individualized storage needs of different industries and different materials. 
5. Wide application range and strong practicality
It is suitable for normal temperature, normal pressure and various pressure conditions. It can be compatible with various non-strongly corrosive industrial materials for storage. The installation is convenient and the operation is simple. No complex debugging is required. It can be put into use directly after installation. 
V. Applicable Industries and Storage Media 
1. Oil storage: Various industrial oils such as gasoline, diesel, lubricating oil, heavy oil, engine oil, hydraulic oil, etc. 
2. Water treatment: Tap water, circulating water, sewage, reclaimed water, industrial cooling water, etc. 
3. Chemical Industry: Neutral chemical solvents, alcohols, aldehydes, non-strong acid and alkali chemical raw materials, industrial additives, etc. 
4. Other fields: Fire-fighting water, emergency storage water, building materials slurry, liquid feed, biological fermentation raw materials, etc. (non-corrosive materials with low corrosivity)
