Learn how flexible hydraulic hose improves construction equipment performance through vibration absorption, pressure transmission, and extended service life. Technical details from Hengshui Zhehan Rubber & Plastic Products Co., Ltd.

The qualification of crimping can be determined through the following multidimensional methods: external dimension verification, structural firmness inspection, sealing performance testing, and internal state re inspection.

The crimping of high-pressure rubber hose joints is mainly based on the crimping process, which is the core operation to ensure a firm seal under high-pressure conditions. The specific methods and key points are as follows:

Check the printing marks on the tube body: The outer layer of hydraulic rubber hoses is usually printed with inner diameter related parameters, and there are two common ways of identification:

The wear between high-pressure rubber hoses and hard pipes is often caused by relative friction, sharp edge scraping due to vibration during operation, or long-term contact friction caused by unreasonable pipeline layout, which can accelerate the loss of the outer rubber layer, expose the steel wire reinforcement layer, and significantly shorten the service life of the hose.
