Chemical hose

 

1. Structure and materials

Chemical hoses are usually composed of three parts: inner layer delivery medium, outer layer shell and middle reinforcement material. The inner layer is in direct contact with the chemical medium, so it is required to have good corrosion resistance and temperature resistance; the outer layer plays a protective and supporting role, usually with high strength and wear resistance; the middle reinforcement material is used to improve the overall strength and pressure resistance of the hose.

 

The inner layer materials of chemical hoses are diverse, such as rubber, polytetrafluoroethylene (PTFE), polyester polyurethane, etc. These materials have different corrosion resistance and temperature resistance, which can be selected according to the specific medium and use environment. The outer layer materials are mostly metal braided mesh, metal spiral tube or polymer material to enhance the strength and pressure resistance of the hose.

 

2. Features and advantages

Corrosion resistance: The inner layer material of the chemical hose can resist the erosion of various chemical media to ensure the purity and transmission efficiency of the fluid.

High temperature resistance: Some chemical hoses can work normally in high temperature environments to meet the transmission needs of high temperature fluids.

Pressure resistance: Due to the reinforcement layer, the chemical hose has a high pressure resistance and is suitable for the transmission of high-pressure fluids.

Good flexibility: The chemical hose has good flexibility and can be easily installed and disassembled in a complex pipeline system, reducing installation and maintenance costs.

Safety protection: The chemical hose can isolate the transported chemicals, prevent leakage and overflow, and protect the working environment and the safety of the staff.

III. Application areas

Chemical industry: used to transport various acids, alkalis, salts and other chemicals.

Health care: used to transport medicines, biological products, etc.

Oil extraction: used to transport oil, natural gas, etc.

Food processing: used to transport food raw materials, additives, etc.

Laboratory: In chemical laboratories, chemical hoses are often used to transport hazardous chemicals to experimental equipment to avoid direct contact.

IV. Maintenance and care

Regular inspection: Check the chemical hose regularly to ensure that its surface is not damaged or aging.

Cleaning and maintenance: Keep the pipeline clean during use to avoid debris and dirt clogging the pipeline.

Avoid excessive bending: Avoid excessive bending of the pipeline during installation and use to avoid damaging the pipeline structure.

Correct storage: When not in use for a long time, the pipe should be stored in a dry, ventilated place to avoid direct sunlight and rain.

5. Precautions

Choose a suitable hose: Choose a suitable chemical hose according to the properties of the conveying medium, working pressure, temperature and other parameters.

Comply with operating procedures: During installation and use, relevant operating procedures should be followed to avoid excessive bending, stretching or extrusion of the hose.

Replace damaged hoses in time: Once the hose is found to be damaged or aged, it should be replaced in time to avoid safety accidents.

In summary, as a special conveying pipeline, chemical hose plays an important role in many fields. It can safely and efficiently transport various chemicals, protect the working environment and the safety of staff, and improve production efficiency.
