Demand for hoses in the chemical industry

In modern chemical production, the transportation and discharge of materials are an integral part. Whether transporting chemical liquids, gases or solid particles, durable and reliable hoses are key equipment to ensure production continuity and safety. Chemical hoses must not only have excellent chemical resistance, but also be resistant to high and negative pressure, as well as have sufficient mechanical strength and flexibility.

Structural features of double-layer high fiber line chemical hose

As an emerging high-performance product, double-layer high-fiber chemical hose is widely used in the chemical industry. Its unique feature is its dual-layer construction combined with high-fiber thread reinforcement, which provides superior strength and abrasion resistance.

Inner material

The inner layer of the chemical hose is the part that directly contacts the medium, so it needs to have excellent chemical corrosion resistance. Corrosion-resistant polymer materials are usually used, such as PTFE (polytetrafluoroethylene), PVC (polyvinyl chloride), etc. These materials are not only resistant to corrosion by corrosive media such as acids, alkalis, and salts, but also have good heat resistance.

High fiber thread reinforcement

Double-layer high-fiber cords refer to the addition of one or more reinforcing layers made of high-strength fibers in addition to the inner polymer layer. Commonly used high fiber materials include aramid fiber, phenolic fiber, etc. These fiber materials have extremely high strength and tensile properties and can provide additional support under high and negative pressure conditions to avoid deformation and breakage of the hose.

Outer protection

In addition to the inner layer and reinforcement layer, the outer layer of the chemical hose is equally important. The outer layer material needs to have good wear resistance, anti-corrosion and anti-aging properties. Commonly used materials include EPDM (ethylene propylene rubber), CR (chloroprene rubber), etc. These materials can effectively protect the inner layer and reinforcement layer from the external environment and extend the service life of the hose.

Excellent performance of double layer high fiber line chemical hose

Resistant to high pressure and negative pressure

One of the biggest advantages of double-layer high fiber line chemical hose is its superior resistance to high and negative pressure. High fiber wire reinforcement provides strong pressure resistance, allowing the hose to withstand extremely high internal pressures without bursting. At the same time, its good structural design also enables it to effectively resist negative pressure under extraction conditions, preventing the hose from collapsing due to excessive internal and external pressure differences.

Chemical resistance

Due to the high corrosion resistance of the inner material, the hose can adapt to various highly corrosive media, including strong acids, strong alkali and organic solvents. This makes it widely used in the chemical industry, such as the transportation of chemicals, the discharge of corrosive waste liquids, etc.

Superior flexibility

Despite its high strength and high pressure resistance, the double-layer high-fiber wire chemical hose retains good flexibility. This makes it easier to operate and install in practical applications, and can adapt to complex pipeline layouts and small work spaces.


Chemical production line

In chemical production lines, high-pressure conveying and negative pressure extraction are common operations. The double-layer high-fiber chemical hose can operate safely in high-temperature and high-pressure environments to ensure that the chemical properties of materials do not change during transportation.

Environmentally friendly waste liquid treatment

In the field of environmentally friendly waste liquid treatment, hoses need to be in frequent contact with highly corrosive waste liquids. Traditional hoses are prone to corrosion and leakage in this situation, while double-layer high-fiber line chemical hoses effectively avoid these problems through the corrosion-resistant material of its inner layer and the high-strength properties of the reinforcement layer.


The petrochemical industry has particularly demanding requirements for transportation equipment. Due to its high pressure resistance and wear resistance, double-layer high-fiber chemical hoses can maintain stable performance during long-term transportation and will not be affected by the external environment. Invalid.

Select and maintain

Choose the right hose

When purchasing a double-layer high-fiber chemical hose, you need to choose a suitable model based on the specific use environment and transmission medium. For example, for high-temperature and high-pressure transportation environments, you should choose a hose with an inner layer made of PTFE material, and an outer layer and reinforced layer made of fiber and rubber materials that can withstand high temperatures.

Proper installation and use

Proper installation and use can extend the service life of the hose. During installation, excessive bending and violent twisting should be avoided to ensure that the hose is well fixed and fitted. During use, hoses should be checked regularly for wear, aging, leakage, etc., and maintained and replaced in a timely manner.

in conclusion

Double-layer high-fiber chemical hose has become an indispensable and important equipment in the field of chemical extraction due to its superior resistance to high pressure, negative pressure and chemical corrosion. Its unique double-layer structure and high-strength fiber reinforced layer not only improve the mechanical properties of the hose, but also effectively extend its service life. Whether it is production line conveying, waste treatment or petrochemical processing, double-layer high-fiber line chemical hose is a reliable choice.

Choosing high-quality double-layer high-fiber chemical hoses can not only improve production efficiency and safety, but also reduce maintenance costs during long-term use and improve the economic benefits of the enterprise.
