What is the general material used for chemical storage tanks?

The chemical storage tank is the equipment for storing chemicals, and the choice of its material is directly related to the corrosion resistance, pressure resistance, heat resistance and other properties of the storage tank. Generally speaking, the materials of chemical storage tanks are mainly as follows:

1.Carbon steel: Carbon steel is a commonly used storage tank material, which is relatively low, but its corrosion resistance is poor and it is susceptible to chemical erosion, so it needs to be treated with anti-corrosion.

2.Stainless steel: Stainless steel is a material with good corrosion resistance, which is relatively high, but its service life is long, not easy to rust, and it is suitable for storing some chemicals that are more corrosive.

3.FRP: FRP is a material with excellent corrosion resistance and pressure resistance, its light weight, high strength, good insulation performance, suitable for storing some chemicals with strong corrosiveness.

4.Polyethylene: Polyethylene is a plastic material with good corrosion resistance and pressure resistance, which is relatively low, but its heat resistance is poor, and it is suitable for storing some chemicals at lower temperatures.

5.Polypropylene: Polypropylene is a plastic material with good corrosion resistance and pressure resistance, which is relatively low, but its heat resistance is poor, and it is suitable for storing some chemicals at lower temperatures.

To sum up, the material selection of chemical storage tanks should be comprehensively considered according to the nature of the stored chemicals, the use environment and use requirements of the storage tank, and other factors, and the appropriate materials should be selected to ensure the safety and reliability of the storage tank.

Chemical storage tanks are generally made of polyethylene PE

It is possible to use polyethylene, and now advocate "replacing steel with plastic".

The rotomolded polyethylene storage tank can fully meet the storage of most chemical liquids, and can be thickened and equipped with a hoop protective sleeve.

According to the medium and the use of working conditions, generally no corrosion at room temperature and pressure using carbon steel, corrosion-resistant oil glass fiber reinforced plastic and plastic, pressure vessels and media have higher requirements for equipment using stainless steel or better alloy steel!

Corrosion-resistant chemical storage tanks can be made of polyethylene, polypropylene, polyvinyl chloride, stainless steel, carbon steel, titanium, steel lined plastic, FRP and other materials. The material of carbon steel storage tank is more than that of Q235.

The problem is indeed a bit big :

Since I asked, I'll give you some examples.

1. Large chemical industries such as coal chemical industry, phosphorus chemical industry, etc., need some atmospheric large vault storage tanks for storing acid, alkali and intermediate materials, generally made of carbon steel or carbon steel lining, etc., with a volume of about 10,000m per tank, and then some pressure storage tanks are needed: such as liquid ammonia spherical tanks, compressed air storage tanks with double heads, etc.

2. The petrochemical industry mostly uses some large floating roof tanks to reduce the volatilization of materials in the storage tank.

3. Fine chemicals are mostly small corrosion-resistant storage tanks (hundreds of liters to dozens of cubic meters), mostly made of shirt acacia tetrafluorine, PE-lined or glass-lined materials. There are also some stainless steel storage tanks used to hold a number of conventional potato dust machine solvents or other non-corrosive materials.

4. Other industries such as pharmaceutical and chemical industries, mainly stainless steel storage tanks.

5. New energy (metallurgical and chemical industry) uses more non-metallic storage tanks, such as PP material, FRP material, etc.

This is based on actual needs, taking into account factors such as cost, usage, storage security, etc., and your question is a bit vague.

1. Metal storage tanks, carbon steel storage tanks, stainless steel storage tanks, aluminum storage tanks, etc., 2. Non-metallic storage tanks, plastic storage tanks, ceramic storage tanks, FRP storage tanks, etc. 3. Metal and non-metallic composite storage tanks, steel-lined PTFE storage tanks, steel-lined polyethylene storage tanks, steel-lined polyolefin storage tanks, steel-lined rubber storage tanks, etc.

Enamel jars are usually used, and other materials are also available, such as glass, special plastics, etc.

From the Internet can only sort out these, if there is a specific demand, it is recommended to go to the hydrochloric acid storage tank manufacturer to understand the details.

The hydrochloric acid storage tank is available in 2 materials, plastic and fiberglass;

1. Considering the short-term investment income, PP plastic storage can be selected, which has low cost and can generally be stored for 3-5 years, which can meet short-term needs.

2. Considering the long-term investment income, you can choose FRP storage tanks, especially those manufacturers that specialize in the production of corrosive liquids.

The plastic storage tank made of PE can hold hydrochloric acid, and there is no problem for the PE storage tank to store chemical liquids, as long as the temperature does not exceed 75 degrees. Hydrochloric acid, sulfuric acid, methanol are all OK. Plastic (polyethylene) storage tank containers do not add any additives, plastic fillers, etc. in the production, completely made of the company's unique formula modified reinforced polyethylene (LLDPE + MDPE + imported PE) materials, from the tank body to the inlet and outlet port, manhole, flange, etc. are the whole one-time forming without welded seams, so the storage tank also has the advantages of no welded seams, no leakage, light weight, low temperature resistance, aging resistance, impact resistance, corrosion resistance, maintenance-free, long life and so on.

Abstract:Chemical storage tank is a storage tank used in the chemical industry and an important infrastructure of the chemical industry. The function of chemical storage tanks is mainly to store and release acid, alkali, alcohol, gas, liquid and other extracted compounds, with excellent performance and long service life.

There are many types of chemical storage tanks, which can be divided into different types according to different classification methods, such as above-ground storage tanks, offshore storage tanks, semi-underground storage tanks, underground storage tanks, submarine storage tanks, etc., and raw material tanks, finished product tanks, intermediate product tanks, waste tanks, etc. Let's take a look at the classification of chemical storage tanks. 1. What is a chemical storage tank?

Chemical storage tank, as the name suggests, is a storage tank used in the chemical industry, mainly used to store chemical raw materials, is a common storage supplies in chemical plants, requiring section dust to have excellent corrosion resistance, and has high strength and long service life.

2. What does a chemical storage tank do?

The chemical storage tank is an indispensable and important infrastructure in the chemical industry, and its main role is to store the extracted compounds such as acid and alkali, alcohol, gas, and liquid.

3. What are the classifications of chemical storage tanks?

There are many types of chemical storage tanks, which can be divided into different types according to different classification methods:

1. Classification by location: it can be divided into above-ground storage tanks, offshore storage tanks, semi-underground storage tanks, underground storage tanks, and sea spring bottom storage tanks.

2. Classification according to oil products: it can be divided into ** storage tank, edible oil tank, lubricating oil tank, fuel storage tank, fire water tank, etc.

3. Classification according to use: it can be divided into raw material tanks, finished product tanks, intermediate product tanks, waste tanks, etc.

4. Classification according to the method: it can be divided into vertical storage tanks, spherical storage tanks, hyperbolic storage tanks (drop-shaped storage tanks), horizontal storage tanks, catenary storage tanks (non-torque storage tanks), etc.

5. Classified by temperature: normal temperature storage tank, low temperature storage tank, high temperature storage tank.

6. Classification according to pressure: atmospheric storage tank, low-pressure storage tank, high-pressure storage tank.

7. Classified according to tank materials: polyethylene storage tanks, rubber storage tanks, FRP storage tanks, ceramic storage tanks, polypropylene storage tanks, stainless steel storage tanks, etc.
