According to the resistance of rubber dielectric properties air brake pipe can be divided into water hose, air hose, acid-alkali pipe, oil pipe, heat pipe, etc., air brake pipe are widely used in industrial and agricultural machinery and equipment. There are various types of fabric hose,this is according to the transmission medium of air brake pipe is different, we choose appropriate materials, transport (positive negative pressure condition) is a kind of used to all kinds of liquid viscous fluid and solid material, such as medium flexible hose.
