Cooling water hose has a wide range of application
In industrial environments facing different corrosive gas emissions, choosing the right material is crucial for industrial hoses. Because different corrosive gases have a great impact on the degree and rate of corrosion of hose materials, improper selection will cause premature damage to the hose, affect production efficiency, and may even cause safety hazards to equipment and personnel. Therefore, selecting industrial hoses of corresponding materials for different corrosive gas emissions is the key to ensuring smooth production.
Industrial waste gas treatment emissions
First, we should understand the properties of different corrosive gases. Gas emissions from different industries will vary. The following industries may produce corrosive gas emissions:
Chemical industry: In the production process, the chemical industry uses a large amount of acids, alkalis, salts and other chemical substances. These substances may produce corrosive gases during the reaction. Such as chlorine, ammonia, sulfur dioxide, etc.
Petrochemical: The petrochemical industry involves a large amount of petroleum processing and natural gas processing. The tail gas and waste gas generated during these processes may contain corrosive gases such as hydrogen sulfide and carbon dioxide.
Metallurgical industry: Iron-making, steel-making, coking and other processes in the metallurgical industry will produce a large amount of waste gas. These include corrosive gases such as sulfur dioxide, nitrogen oxides, and chlorine.
Machinery manufacturing: During the machinery manufacturing process, metal cutting, welding and other operations will produce high-temperature waste gas. It may contain corrosive gases such as hydrogen chloride, hydrogen fluoride, etc.
Textile printing and dyeing: Chemicals used in the textile printing and dyeing process may produce corrosive gases. Such as hydrogen chloride, sodium hypochlorite, etc.
Electric power industry: Coal-fired power generation and gas-fired power generation in the electric power industry will produce a large amount of waste gas. These include corrosive gases such as sulfur dioxide, nitrogen oxides, and carbon dioxide.
Corrosive gas exhaust hose selection
We can choose industrial hoses of different materials for different gases:
PTFE hose
This hose has very good chemical stability and corrosion resistance. It can be used to transport various corrosive gases, such as hydrofluoric acid, concentrated acid, concentrated alkali, etc.
silicone rubber hose
Silicone rubber has excellent high temperature resistance, oxidation resistance, corrosion resistance and other properties, and can be used to transport some corrosive gases, such as chlorine, ammonia, etc.
Polyurethane hose
This kind of hose has good corrosion resistance and can be used to transport some weakly acidic and weakly alkaline corrosive gases.
Fluoroplastic composite hose
This kind of hose is made of PTFE, metal and other materials. It has excellent corrosion resistance and mechanical properties and can be used to transport various corrosive gases.
