We often use hoses in our life. In the process of using hoses, we should pay attention to whether hoses are abnormal. Here are the ways to check whether the PVC hoses are abnormal.
First of all, we can confirm whether the appearance of PVC suction hose is abnormal, such as trauma, hardening, softening, discoloration, etc. During the normal use of hoses, periodic inspection must be carried out once a month. The service life of the hose is largely influenced by the characteristics, temperature, velocity and pressure of the fluid. When abnormal signs are found during pre-operation inspection and periodic inspection, please stop using immediately, repair or replace new hoses.
