High-performance chemical hose: a new industrial choice for acid, alkali and corrosion resistance

 

In modern industrial production, the selection of chemical pipelines is crucial. Especially when it comes to the transmission of corrosive chemicals, choosing a reliable and durable hose can effectively improve production efficiency and reduce maintenance costs. This article will explore in detail the characteristics of chemical solvent resistant hoses, especially the advantages of EPDM hoses.

 

The importance of chemical solvent resistant hoses

 

In the chemical, petrochemical, pharmaceutical and other industries, there are many types of chemicals, including acids, alkalis, solvents, etc. During the transportation of these chemicals, if improper pipe materials are used, it is very easy to cause corrosion, leakage or other dangers, which not only affects production safety, but also may cause environmental pollution. Therefore, it is particularly important to choose chemical solvent resistant hoses.

 

Ideal characteristics of chemical solvent hoses

 

1. Corrosion resistance: A high-quality chemical solvent hose should be able to resist the erosion of various corrosive chemicals. Different chemicals have different corrosion characteristics, and the hose material needs to have a wide range of chemical resistance.

 

2. High/low temperature resistance: Many industrial chemical reactions need to be carried out at extreme temperatures. Therefore, the hose must be able to withstand high and low temperature environmental changes and maintain stable performance.

 

3. High mechanical strength: During industrial use, the hose needs to withstand certain mechanical pressures, including bending, stretching and compression. Therefore, mechanical strength is an important criterion for ensuring service life and safety.

 

4. Abrasion resistance: Chemical solvent hoses need to have good abrasion resistance to ensure that they are not easily damaged during long-term use.

 

Advantages of EPDM hoses

 

EPDM is known for its excellent chemical resistance and environmental adaptability and is widely used in liquid transportation in the chemical industry.

 

1. Excellent chemical resistance

 

EPDM has excellent antioxidant, ozone and acid and alkali resistance. In particular, it has shown good resistance to some common acids (such as nitric acid, phosphoric acid) and alkalis (such as sodium hydroxide). This means that in the chemical industry, it can effectively reduce the risk of chemical corrosion and ensure the safe transportation of materials.

 

2. Excellent heat and cold resistance

 

EPDM hose can withstand a wide temperature range of -40℃ to 100℃, which allows it to maintain its elasticity and mechanical strength in different temperature environments. Whether in the cold winter or the high-temperature chemical workshop, EPDM hose can do the job perfectly.

 

3. Excellent mechanical properties

 

Compared with other types of hose materials, EPDM shows higher tensile and compression resistance. This property greatly reduces the risk of damage to the hose due to mechanical stress during use.

 

4. Eco-friendliness

 

EPDM does not contain halogens and does not release harmful gases during combustion, which meets environmental protection requirements. In addition, it can be recycled and reused to further reduce the impact on the environment.

 

Application areas

 

Due to its wide range of excellent properties, EPDM hose has been widely used in many industries.

 

1. Chemical industry: Used to transport acid and alkali solutions, chemical solvents and other corrosive liquids to ensure the safety and stability of the transportation process.

 

2. Pharmaceutical industry: In the pharmaceutical process, pollution needs to be strictly controlled, so it is particularly appropriate to use hoses with strong chemical resistance.

 

3. Agricultural irrigation: It is not only used to transport chemical fertilizers, but also resists pesticide erosion and improves agricultural production efficiency.

 

4. Food industry: Although it is mainly used for chemical material transportation, its non-toxic properties also make it limited in use in some food processing equipment.

 

Precautions for selecting EPDM hoses

 

When selecting suitable EPDM hoses, you should pay attention to the following points:

 

1. Chemical compatibility: Make sure that the selected hose material can resist all chemical components in the application environment.

 

2. Working pressure: Confirm that the hose can support the pressure range of special applications to avoid the risk of rupture due to overload.

 

3. Temperature adaptability: Check the temperature adaptability range to ensure that it can still operate normally under extreme temperature conditions.

 

4. Certification and standards: Select products that meet industry standards and relevant safety certifications to ensure quality and safety.

 

Conclusion

 

When choosing industrial chemical hoses, EPDM hoses are undoubtedly the ideal choice for acid, alkali and corrosion resistance. Through the information provided in this article, I hope to help you better understand and choose chemical piping products that suit your needs. Choosing the right hose not only improves the safety and efficiency of industrial production, but also saves a lot of maintenance and replacement costs for enterprises.
