Classification of Large Diameter Rubber hose

There are many types of large-diameter dredging rubber hoses, and their technical processes are also different. Large-diameter rubber hoses with different structures and different skeletons have different processing methods for the skeleton layer and hose forming equipment.

Shandong Hesper’s large-diameter rubber hose is composed of medium-resistant synthetic rubber inner rubber layer, multi-layer cloth/cord/steel wire winding reinforcement layer, and synthetic rubber outer rubber layer which has good weather resistance and wear resistance.

According to the working pressure state, large-diameter rubber hoses can be divided into high-pressure large-diameter rubber hoses and low-pressure large-diameter rubber hoses. Among them, low-pressure large-diameter hoses are further divided into low-pressure delivery large-diameter rubber hoses (positive pressure) and low-pressure suction large-diameter rubber hoses (negative pressure).

The skeleton layer of the low-pressure large-diameter rubber hose is a multi-layer fabric/cord winding reinforcement layer, plus a spiral steel wire skeleton reinforcement layer. The negative pressure suction hose adopts a double-layer spiral steel wire skeleton reinforcement layer to ensure the pipe body does not suck or deform.

Large-diameter hoses are divided into large-diameter water delivery hoses, large-diameter mud suction and discharge hoses, large-diameter oil-resistant hoses, large-diameter acid and alkali-resistant hoses, large-diameter high-temperature resistant hoses, large-diameter steam hoses, and large-diameter wear-resistant hoses.

Large-diameter water hoses are mainly used for conveying or pumping water and other neutral liquids at room temperature, mainly used for industrial suction and drainage, agricultural and forestry irrigation, urban drainage, etc.; 

• 
• Large-diameter mud suction and discharge hoses are mainly used for dredger operations, port terminals River dredging;
  
  
  Large-diameter oil-resistant hoses are mainly used for the transportation and suction of gasoline, diesel, kerosene, lubricating oil, emulsified oil, spark oil and other media;
  
  
  Large-diameter high-temperature resistant hoses are mainly used for high-temperature occasions, such as superheated water and saturated steam, etc. ;
  
  
  Large-diameter wear-resistant rubber hose is mainly used for solid particle powder medium transportation and suction, and cement mortar transportation.
