Rubber lined pipe mainly utilizes the unique properties of rubber, such as high elasticity, high air tightness, impact resistance, wear resistance, chemical medium resistance, vibration absorption, etc., and has good adhesion with metal objects; through the physical and chemical properties of rubber itself, the effect of pipeline conveying medium on external structure such as impact force and corrosion is reduced. Due to the buffering effect of rubber, the service life of the pipeline is greatly extended, and the cost of users is reduced. Therefore, it is suitable for the anti-corrosion lining of various pipelines and tank equipment, and is widely used in desulfurization, chemical industry, metallurgy and other industries.

- Application principle

Use the "softness over hardness" of rubber to solve the pipe lining mainly based on wear resistance, and use the high corrosion resistance and high temperature resistance of rubber to protect the transmission pipeline.

- Advantages of use
1. Excellent structure

The reinforced skeleton steel pipe of the pipe and the rubber layer are compounded into a whole using high-performance adhesives, which overcomes the shortcomings of steel pipes that are not resistant to pressure, plastics and rubbers that are not resistant to pressure, and glass fiber reinforced plastics that are brittle and have poor impact resistance. At the same time, it has the common advantages of steel pipes and wear-resistant rubber, and has a high comprehensive cost-effectiveness.

2. High strength and high impact resistance

The rubber elastomer has low density, light weight, good vibration absorption performance and excellent mechanical impact resistance, high strength, good rigidity, no creep, strong impact resistance, earthquake resistance, and water hammer resistance, and is easy to transport, install and maintain.

3. Wide temperature adaptability

Desulfurized rubber lined pipes can be used for a long time in the range of -50°C to +150°C, and the rubber lining will not be separated from the steel frame due to temperature changes.

4. Energy saving

Good lubricity, small running resistance loss, saving running costs. The reinforced skeleton steel pipe and the rubber layer of the pipe are compounded into a whole using high-performance adhesives, which overcomes the shortcomings of steel pipes that are not resistant to pressure, plastics and rubbers that are not resistant to pressure, and fiberglass that is brittle and has poor impact resistance. At the same time, it has the common advantages of steel pipes and wear-resistant rubber, and has a high comprehensive cost-effectiveness.

5. Good performance, the service life generally reaches more than 15 years (theoretical value) under normal use pressure and temperature. After 6-8 years of use, the pipeline is rotated nearly 90° once, and the service life will be longer. The rubber lined pipe can be repeatedly lined with rubber for 4 times, which reduces costs, shortens the production cycle, and ensures the construction period.
