Wear resistance of asphalt rubber hose

The asphalt rubber pipe can be used for sewage pipes, rainwater pipes, and can also be used to transport various chemical liquids, sewage and various corrosive media.

  1. The asphalt rubber pipe can be used for sewage pipes, rainwater pipes, and can also be used to transport various chemical liquids, sewage and various corrosive media.
  2. The asphalt rubber hose is corrosion-resistant, has good wear resistance and long service life.
  3. The asphalt rubber hose is suitable for various pipe joints, and can be used for pipeline plugging projects and maintenance of pipelines.
  4. The asphalt rubber hose is resistant to low temperature, and can still maintain elasticity and flexibility at -60°C, and its hardness will not change under low temperature conditions.
  5. The asphalt rubber tube has strong anti-ultraviolet ability, and can keep the color unchanged under direct sunlight.
  6. The asphalt rubber hose has good corrosion resistance, and its performance against acid, alkali and other chemical media is stable.

First, appearance

The appearance of the asphalt super wear-resistant rubber pipe is generally divided into two parts: the pipe body and the joint. The body of the asphalt super wear-resistant rubber hose is generally white, uniform in color, no spots, no cracks, and the surface is smooth, no wrinkles, no nodules, etc. The joint is black or yellow, uniform in color, without obvious cracks and bubbles. There are no obvious gaps, slag inclusions, etc. at the connection between the pipe body and the joint.

Second, the tube body

  1. Material of asphalt rubber hose: natural rubber, styrene-butadiene rubber, neoprene rubber, EPDM rubber.
  2. The hardness of the asphalt rubber tube: 70-90 degrees.
  3. Heat aging resistance of asphalt rubber hose: it can work for more than 20 years at 80 degrees, and more than 10 years at -40 degrees.
  4. Oil resistance of asphalt rubber hose: within a certain pressure range, the medium is acid, alkali, oil, etc., and it can be used for a long time without deterioration.
  5. Wear resistance of asphalt rubber hose: within the specified pressure range, the greater the thickness of the pipe body, the better the wear resistance. And the smoother the inner wall of the tube, the better the wear resistance.

Third, the structure

The asphalt rubber hose consists of an inner rubber layer and an outer rubber layer. Its main features are:

  1. The asphalt rubber hose has high wear resistance while maintaining good elasticity and flexibility.
  2. The asphalt rubber hose has strong oil resistance and aging resistance, and can be used in various harsh environments for a long time, especially suitable for the transportation of various chemical liquids, chemical media, sewage and other media.
  3. The outer surface of the asphalt rubber tube is coated with a layer of transparent wear-resistant paint to protect the internal rubber from corrosion.
  4. The asphalt rubber tube has good electrical insulation performance and can be used for various power cable protection tubes.
  5. The asphalt rubber hose has good anti-ultraviolet ability and can be used outdoors for a long time.

Fourth, installation

  1. When the rubber pipe is connected with the pipe, flange and joint, the butt joint must be used, and the flange connection must be welded, and the joint must not have slag inclusion and welding.
  2. When the rubber tube is connected to the pipe fittings, it must be ensured that the size of the inner and outer ports at the end of the rubber tube is consistent.
  3. During the transportation, loading and unloading and storage of the rubber tube, avoid impact, drop, heavy pressure and mechanical damage.
  4. The correct direction of the asphalt super wear-resistant rubber tube should be maintained during installation.

Fifth, the connection method

The asphalt rubber pipe is suitable for various pipe joints, such as stud bolts, threaded joints, flange connections, etc., and adopts different connection methods to meet the connection requirements of different pipe materials. The asphalt rubber hose is suitable for installation, maintenance and replacement of pipelines. The diameter of the asphalt rubber pipe has various specifications such as DN15 and DN80. The joints of the asphalt rubber pipe include internal thread stud bolt (BVB) joints and external thread stud bolt (BVV) joints. When installing the asphalt rubber pipe, Different joint methods can be selected according to pipe materials and usage requirements.
