1、 Principles for selecting chemical transport hoses

In chemical production, corrosive chemicals often have characteristics such as strong corrosiveness, flammability and explosiveness, toxicity and harm. Therefore, when choosing chemical conveying hoses, the following principles must be followed:

 

Material adaptability

It is crucial to choose the appropriate hose material based on the properties of corrosive chemicals. For example, for highly corrosive media, polytetrafluoroethylene (PTFE) hoses are widely used due to their excellent corrosion resistance. PTFE hoses can withstand almost all known chemicals such as acids, alkalis, solvents, etc., ensuring that they will not corrode the inner wall of the hose during transportation. In addition, silicone hoses are suitable for high-temperature media, while polyurethane hoses are suitable for low viscosity media. For special occasions, metal materials such as stainless steel are also used due to their excellent corrosion resistance.

 

Work pressure and temperature range

When choosing chemical transport hoses, it is necessary to consider their working pressure and temperature range. Ensure that the hose can withstand the working pressure of the medium during use, while maintaining stable performance within the specified temperature range. Prevent safety hazards such as hose rupture and leakage due to excessive working pressure or high temperature.

 

Size and bending radius

The size and bending radius of the hose directly affect the conveying efficiency and adaptability of the hose in the installation environment. When selecting hoses, the appropriate size and bending radius should be chosen according to the requirements of the conveying system. Ensure that the hose can flexibly adapt to various complex environments during installation, while ensuring conveying efficiency.

 

Safety and reliability

The safety and reliability of chemical transport hoses are factors that cannot be ignored in the selection process. Verified products should be selected to ensure stable performance of the hose during use. At the same time, establish a regular inspection plan to check for any damage, wear, or aging on the surface of the hose, and promptly identify and address potential safety hazards.

 

2、 Safety performance of chemical conveying hoses

Chemical transport hoses play an important role in ensuring the safe transportation of corrosive chemicals. Its safety performance is mainly reflected in the following aspects:

 

Corrosion resistance

Chemical transport hoses are made of corrosion-resistant materials such as PTFE, silicone, etc., which can withstand the erosion of various corrosive chemicals. During the transportation process, the inner wall of the hose will not be damaged due to chemical corrosion, ensuring the safety of the transportation system.

 

High temperature and low temperature resistance performance

Some chemical transport hoses, such as silicone hoses, can maintain stable performance in high or low temperature environments. This ensures that the hose will not experience safety hazards such as deformation or cracking when transporting high-temperature or low-temperature corrosive chemicals.

 

Sealing performance

Chemical conveying hoses use professional connection methods such as flanges, quick couplings, etc. to ensure tight sealing under high pressure conditions. Avoiding gas or liquid leakage caused by loose or aging joints, ensuring the safety of the transportation process.

 

Flexibility and adaptability

Chemical transport hoses have good flexibility and adaptability, and can flexibly adapt to various complex environments and installation requirements. This enables the hose to reduce vibration and impact during transportation, reducing damage to the conveying system.

 

Environmental Protection and Sustainability

With the increasing awareness of environmental protection, more and more chemical conveying hoses are being made of recyclable and biodegradable materials. This reduces environmental pollution and promotes the development of green chemicals.

 

3、 Development trend of chemical conveying hose industry

With the rapid development of the global chemical industry, the demand for efficient, safe, and environmentally friendly pipeline materials is increasing day by day. The chemical conveying hose industry is developing in the following directions:

 

Material modification

By adding special additives or blending modification, the comprehensive performance of the hose such as wear resistance, temperature resistance, and aging resistance can be further improved. This helps to extend the service life of the hose, reduce replacement frequency and cost.

 

Environmentally friendly and sustainable

Develop recyclable and biodegradable materials to reduce environmental pollution. At the same time, strengthen the recycling of hose materials and promote the development of green chemistry.

 

Customized services

With the increasing demand for personalization and customization in the market, the chemical conveying hose industry has begun to provide customized services. According to the specific needs of customers, provide hose products that comply with standard specifications to meet their personalized needs.

 

Intelligent application

Apply intelligent technology to chemical conveying hoses, such as intelligent monitoring and warning systems. By monitoring the usage status of hoses in real-time, potential safety hazards can be identified and addressed in a timely manner, thereby improving the safety and reliability of the conveying system.

 

International standardization

With the increase of international trade and the development of the global chemical industry, the chemical conveying hose industry is moving towards international standardization. Develop unified standard specifications to ensure that the quality and safety of hose products comply with international standards.

 

In summary, chemical transport hoses play an important role in ensuring the safe transportation of corrosive chemicals. When selecting hoses, principles such as material adaptability, working pressure and temperature range, size and bending radius, as well as safety and reliability should be followed. At the same time, pay attention to the safety performance of hoses, such as corrosion resistance, high and low temperature resistance, sealing performance, flexibility and adaptability, as well as environmental protection and sustainability. With the rapid development of the global chemical industry, the chemical conveying hose industry is moving towards material modification, environmental sustainability, customized services, intelligent applications, and international standardization. Through continuous innovation and improvement, chemical conveying hoses will provide stronger guarantees for the safety and efficiency of chemical production.
