Producing Process and Maintenance of Layflat Rubber Hose

Layflat rubber hose (also called folded rubber hose) is one kind of large diameter rubber hoses which Hesper make. The main material used in the manufacture of this rubber hose is synthetic rubber, with different rubber formulations selected based on varying application requirements. Common rubber types include nitrile rubber, neoprene rubber, and silicone rubber, each with its specific applications. For example, some rubber varieties offer better resistance to oils and greases, while others are better suited for high-temperature environments. This diversity of materials allows folded rubber hoses to adapt to a variety of complex working conditions.  

Production process of layflat rubber hose

The production of layflat rubber hose is a complex and meticulous process involving multiple technological steps. The first step is rubber compound preparation, where raw rubber is mixed with various additives according to a specific formula and then compounded using an internal mixer to ensure uniform distribution of the components. Temperature and time control are crucial in this process, directly affecting the performance of the final product. Next is the molding process, where the compounded rubber is extruded to form a tube blank, and then a reinforcing layer is embedded within the blank.

The weaving or winding of the reinforcing layer is a key step determining the hose's pressure-bearing capacity. Modern production often uses automated weaving equipment to ensure the reinforcing layer is evenly covered on the tube blank surface. After the reinforcing layer is processed, an outer rubber overlay is applied to make the pipe structure more complete. Finally, in the vulcanization stage, the molded pipe is placed in a vulcanizing tank, where a chemical reaction occurs under specific temperature and pressure, causing the rubber molecules to cross-link and form a stable three-dimensional network structure, thereby obtaining the desired physical properties.

Quality monitoring is maintained throughout the entire production process. From raw material inspection upon arrival to finished product testing before shipment, each step has strict standard requirements. The process control for the folded parts is particularly stringent, requiring that repeated folding prevents cracking or damage.

Usage Precautions and Maintenance

Proper use and maintenance are key to ensuring the performance of folded rubber hoses and extending their service life. Before use, carefully inspect the hose's appearance to ensure there are no scratches, bulges, or other obvious defects. For first-time use, a pressure test is recommended to ensure the hose's sealing performance meets requirements.

During installation, avoid excessive bending or twisting, especially in low-temperature environments where the rubber material hardens. Handle with extra care to prevent damage. Ensure the working pressure is within the hose's rated pressure range during use, avoiding sudden pressure surges, which may damage the hose structure.

For daily storage, clean and completely dry the hose. Fold it according to its natural bending radius; do not force it backwards. Store in a cool, dry environment, avoiding direct sunlight and high-temperature heat sources. Keep it away from oils, chemicals, and other substances that may corrode the rubber. Regular inspection is essential maintenance, it is recommended to conduct a thorough inspection of in-use folded rubber hoses every three months, paying particular attention to joints and frequently folded areas.

If cracks, hardening, deformation, or other signs of aging are found in the hose, replace it immediately. Under normal circumstances, the lifespan of a properly used folded rubber hose can reach several years, but the specific replacement cycle depends on the actual frequency of use and the working environment.
