How to properly store and maintain wear-resistant and anti-aging PVC welding hose to avoid aging?

Although the wear-resistant and anti-aging PVC welding hose has strong durability, it may still age, harden, crack or degrade in performance if the method is not appropriate during long-term use and storage. In order to extend its service life and ensure the safety and efficiency of welding work, correct storage and maintenance measures need to be taken.

The storage environment has a great impact on the service life of PVC welding hose. It is recommended to store the hose in a dry and ventilated indoor environment, avoiding direct sunlight, high temperature or extremely cold environment. Ultraviolet rays will accelerate the aging of PVC materials, making them hard and lose flexibility, while too low a temperature may cause the hose to become brittle and affect its bending performance. Therefore, when storing, avoid exposing the hose to sunlight or severe cold weather for a long time. If it must be stored outdoors, it is recommended to use a cover or protective cover for protection.

It is also key to avoid contact between the hose and corrosive substances. In the welding work environment, there may be oil, chemical solvents, welding slag or other corrosive substances, which may cause damage to the PVC hose. During storage and use, the hose should be kept away from direct contact with acids, alkalis, oils or solvents, and the hose surface should be wiped with a clean damp cloth after use to remove residual welding slag and stains to ensure that its surface is clean and pollution-free.

Reasonable storage methods can also effectively prevent hose deformation and damage. Long-term bending, excessive winding or squeezing will cause creases or breaks in the PVC hose. When storing, the hose should be coiled into a larger circle to avoid excessive bending or knotting. The hose should not be placed under heavy objects or squeezed for a long time to prevent its deformation or internal damage.

During daily use, correct operation can also help reduce the aging rate of the hose. For example, during welding operations, do not keep the hose close to high-temperature welding flames or welding slag splashing areas for a long time to prevent high temperature scalding or burning through the hose surface. Avoid dragging the hose on the ground during use to reduce friction loss with rough surfaces, thereby extending its durability.
