Rubber straws used in dredging projects are generally the optimal choice. Unlike the positive pressure of the discharge pipe, these straws operate under negative pressure. They are equipped with a skeleton for support to prevent collapse due to suction, and are mainly used to absorb silt, sediment, and other materials.

Structure:Abrasion-resistant layer: This layer ensures long – term wear resistance during the material absorption process.Reinforcement layer: Composed of high – strength fibers and steel wires or steel rings, it provides strong resistance against collapse under suction.Outer adhesive layer: It features corrosion resistance, ultraviolet resistance, ozone resistance, and anti – aging properties.

Features:Abrasion resistance: The rubber material’s high abrasion resistance effectively reduces the friction caused by silt and sand during dredging operations.Corrosion resistance: It can withstand the corrosion of seawater and various chemical substances well.Flexibility: The rubber’s good flexibility makes it easy to lay and use in complex terrains.Compressive resistance: It can bear high internal pressure, ensuring it doesn’t break easily when absorbing silt and sand.

Applications:River channel dredging: Used to clear silt and sediment in river channels, maintaining smooth water flow.Port dredging: Applied in ports and docks to ensure safe ship passage.Mine tailings treatment: Used for absorbing sediment and waste from mine tailings.Sewage treatment: Capable of absorbing sludge from sewage treatment plants.Maintenance:

Regular inspection: Check the rubber tube for signs of wear, cracks, or aging.Cleaning: Clean the silt and sand from the pipeline promptly after use to prevent blockages.Storage: Store the rubber tube away from direct sunlight and high – temperature environments to extend its service life.Usage: Rotate the tube after a period of use to avoid prolonged wear on the same inner glue layer area.

Selection Factors:Working condition – based selection: Select the appropriate rubber tube according to working conditions such as silt type, flow rate, and pressure.Brand and quality: Opt for brands with extensive production experience and reliable quality to ensure operational safety and efficiency.
