How does a 3/8 cloth-covered high-pressure sandblasting hose maintain flexibility?- Ningbo Shunlong Rubber Hose Co., Ltd.

The 3/8 cloth high pressure sandblasting hose can maintain its flexibility, which is inseparable from the high quality materials it uses. The inner and outer layers of this type of hose are usually made of durable and elastic synthetic rubber as the main material. This rubber material can not only withstand the impact of high-pressure fluid, but also has excellent flexibility, allowing the hose to bend easily during use. The woven fabric in the sandwich layer enhances the overall structural strength without significantly increasing stiffness. Woven fabrics are usually made of high-strength fibers that effectively disperse the pressure on the pipe wall and form a perfect combination with the rubber material, achieving both flexible and durable performance.

Structural design is also an important factor in hose flexibility. The design concept of the cloth-covered high-pressure sandblasting hose is to ensure its high strength while retaining flexibility to the greatest extent. The wall thickness is precisely calculated so that it is neither too thin to reduce the pressure resistance nor too thick to cause difficulty in operation. The braided fabric in the reinforcement layer is woven in an interlaced pattern, which allows the hose to remain stable when subjected to high-pressure fluids while reducing resistance when bending. The outer fabric design provides additional protection for the hose, which is both wear-resistant and non-slip, making the hose more flexible and safer during use.

In order to maintain this flexibility, correct use and maintenance are also particularly important. In daily use, operators need to avoid excessive bending of the hose or keeping it in an extreme bending state for a long time to avoid causing irreversible damage to the material structure. Avoiding long-term exposure of the hose to static high pressure is another key measure to maintain its flexibility. If a hose remains stationary for a long time under high pressure, its internal structure may become hardened due to the continuous force and lose its original elasticity.

External maintenance of the hose should not be neglected either. Sandblasting hoses are easily exposed to various abrasive particles or corrosive substances during use. Regularly cleaning dirt or grease on the surface of the hose can effectively reduce the damage of the external environment to the flexibility of the material. When not in use, the hose should be stored in a dry environment away from direct sunlight or extreme temperatures. Too high a temperature will accelerate the aging of the rubber, while low temperatures may cause the material to become brittle and affect its flexibility. In order to extend the service life, you can also regularly apply rubber protective agent to the outer layer of the hose to improve its anti-aging ability.
