1, Specification of dredging rubber hose
The dredging hoses are divided into below different types according to different dredging medium.
Large-diameter water delivery hose: mainly used for reporting or pumping water and other ZTE liquids at normal temperature, for industrial suction and drainage, agricultural and forestry irrigation, urban drainage, etc.;
Large-diameter suction and discharge hose: mainly used for dredger homework, river dredging at port and port;
Large-diameter oil-resistant hose: mainly used for the reporting and suction of gasoline and diesel, petroleum, emulsified oil, spark and other media;
Large diameter high temperature resistant hose: mainly used in high-temperature places, such as
superheated water and saturated steam;
Large-diameter wear-resistant hose: It is mainly used for the reporting and suction of solid granular powdered media, as well as the reporting of cement mortar.

3, Characters
1. The large-diameter suction and discharge hose is made of special synthetic rubber with a thickened inner rubber layer, which has high wear resistance.
2. The suction and discharge mud hose body has the advantages of small outer diameter tolerance, excellent water resistance, soft and durable hose body;
3. The small burst pressure of the hose can reach four times the working pressure.
4. According to the different working conditions, the suction and discharge rubber tube is made of corresponding materials. The product structure is reasonable in design, excellent in quality, strong and durable
