Sodium bicarbonate used in a cleaning machine causes hoses to wear and is very dangerous

A customer had a cleaning apparatus that uses air to blow sodium bicarbonate to clean metal parts used in rolling stock (train cars). The wear on the PVC hose conveying the sodium bicarbonate was so heavy that the hose would break in less than a month, causing the sodium bicarbonate to leak. Operation would have to be stopped because of the high level of danger this posed.

It has been half a year since switching to the chemical resistant and non-adhesive TOYOFUSSO Hose. The inner surface has not been worn and the hose displays high wear resistance compared to PVC, which should significantly expand the frequency of replacement.
