1. Material of large-diameter suction and discharge hoses

Rubber type: Large-diameter suction and discharge hoses are usually made of highly weather-resistant and wear-resistant rubbers, such as EPDM (ethylene propylene diene monomer rubber), NBR (nitrile rubber), etc. These materials not only provide good chemical resistance, but also withstand extreme weather conditions and physical damage.


Reinforcement materials: In order to ensure the structural stability and durability of the hose, some reinforcement materials such as polyester fiber, nylon or steel wire are often added to the hose during the manufacturing process. These reinforcement materials help prevent the hose from collapsing under negative pressure or extreme conditions. Among them, the spiral steel wire ensures that the large-diameter suction and discharge hose can withstand negative pressure, not be sucked flat, and not deformed.

2. Uses of Large-diameter Suction and Discharge Hose

Industrial Applications: In industrial settings, large-diameter suction and discharge hoses are widely used to transport oil, chemicals, water, and other liquids. They are often used in oil depots, chemical plants, and water treatment facilities, and their chemical resistance and high strength make them ideal for these environments.


Agricultural Applications: In agriculture, this hose is used in irrigation systems to effectively transport large amounts of water to farmland. They are also used to drain and clean ponds, rivers, and other water bodies, helping to maintain the cleanliness and efficiency of water conservancy facilities.


Construction Applications: In the construction industry, large-diameter suction and discharge hoses are used to pump out water from construction sites, treat wastewater, and clean up spills in concrete mixing plants. In addition, they are often used in urban drainage systems to treat rainwater and domestic sewage.


To summarize, large-diameter suction and discharge hoses have become one of the indispensable equipment in the fields of industry, agriculture, and construction due to their powerful functionality and diverse application backgrounds. Understanding the material and purpose can help users better select and use this equipment, thereby improving work efficiency and reducing operating costs while ensuring safety and environmental protection.
