Steel Rubber Composite Pipe

Steel-rubber composite pipe has good corrosion resistance, wear resistance and impact resistance. It is widely used in fine tailings conveying system of mines in metallurgy, electric power, chemical, petroleum, coal, cement and other industries, coal-fired power plant ash conveying system, chemical anti-corrosion, coal mine backfilling and Rivers, port dredging, pipelines and other fields. It is especially suitable for working with a delivery temperature between -50 °C and +120 °C.

Main Feature

Characteristics of steel and rubber composite pipe

1.a wide range of applications Wide application

The steel-rubber composite pipe can be used for a long time under the environment of -50 ° C ~ +120 ° C. The lining rubber will not be separated from the steel pipe due to temperature changes.

2.very high impact resistance.

The rubber deforms under impact, absorbs the kinetic energy of the particles, and then returns most of the energy back to the particles in the form of bounce, reducing the impact force and greatly improving the service life.

3,.good wear resistance

The rubber lining can be formulated according to the needs of wear resistance, and its wear resistance is more than five times that of steel pipes and more than four times that of ceramics.

  1. Good anti-corrosion performance.

The rubber lining can be formulated according to the requirements of anti-corrosion. It is suitable for corrosive environment. The steel-rubber composite pipe can resist corrosion of various acids, alkalis, salt and sewage, and can be used in complex and harsh chemical corrosion environments.

  1. The running resistance is small and the energy consumption is reduced.

The rubber-lined steel tube produced by our company is produced by high-pressure air bag extrusion process. The inner wall is smooth, compact and impervious, saving operating costs and reducing costs.

  1. Light weight, easy to install and maintain.

The steel frame of the rubber-lined steel pipe only acts as a bearing, and can be thinned to the minimum pressure level. Its weight is 20-30% lighter than ordinary steel pipe, and the rubber-lined steel pipe is not afraid of bumping, the lining will not be broken, and the rubber-lined steel pipe is used. The service life is 4-5 times higher than that of pure steel pipe. The average annual investment is low during the service life, and the weight is light, the bracket cost can be saved, the resistance consumption is small, the operation cost is saved, and the comprehensive cost of the rubber-lined steel pipe is greatly reduced, which can save the user. A lot of money.

  1. Can be recycled.

The steel pipe only needs one-time investment. The used old steel pipe can be used after repairing the rubber. The rubber is equivalent to 4-5 times of the life of the metal pipe. Further saving money, energy saving and environmental protection.

Technical Specification

Specifications of “Five” steel and rubber composite pipeSteel and rubber composite pipes are divided into shapes: straight pipes, curved pipes, elbows, tees, etc.

  • Steel and rubber composite pipe according to pipe diameter: DN80-DN630. See Table 1 for details.
  • According to the thickness of the inner lining of the tube: can range from 4.5mm to 12mm, can also be determined according to customer requirements to determine the thickness of the rubber production.
  • Seamless steel pipe lined steel and rubber composite pipe specification sheet / (Table 1)
