这是一种可方便拆装、重复使用,密封良好的组合式接头。经生产实践证明,可延长波纹体不锈钢软管的使用寿命3—8倍。 波纹体不锈钢软管的管壁较薄,约0.5mm,比橡胶管轻3—5倍,且不易弯折成“死角”。因此,在石油化工生产中得到较广泛的应用。 波纹体不锈钢软管经一段时间使用后(一般1—4年,个别不足1年),在软管和硬管的接合处,首先出现破裂,引起介质泄漏,这是因为在软管和法兰的压合处,柔性较差,由于软管管壁薄,操作时,活动范围大,往往是接近压合处的软管承受最大应力
This is a modular connector that is easily removable, reusable, and well-sealed. Proved by the production practice, extend the service life of corrugated stainless steel hose 3-8 times. Corrugated stainless steel hose wall thinner, about 0.5mm, 3-5 times lighter than the rubber tube, and not easy to bend into a “dead end.” Therefore, in the petrochemical industry has been more widely used. Corrugated stainless steel hose after a period of time (usually 1-4 years, respectively, less than 1 year), in the hose and pipe joints, the first rupture, causing medium leakage, it is because the hose and flange Of the pressure at the office, less flexible, due to thin hose wall, the operation, the scope of activities, often close to the pressure of the hose to withstand the maximum stress
