Standard Corrugated Metal Hose With Spiral Wave Type

According to the standard of GB/T14525-2010 (General specification of corrugated metal hose assemblies) , we Have improved our technology of making corrugated metal hoses to satisfy the standard needs, and related experiments were passed by authorities. Below are related definitions and technical terms : DN（mm）— Inside nominal diameter, Inside diameter of corrugated metal hose is not smaller than the 98% of Inside nominal diameter ID （mm）— Inside diameter OD （mm）— Outside diameter Pd（Kgf/c㎡）— Dynamic working pressure, means at normal temperature, dynamic test conditions, the highest working pressure the hose can endure. Rd（mm）— Dynamic bending radius, means at normal temperature, dynamic test conditions, the smallest bending radius the hose can reach, and the bending cycles is not less than 50000 times. — Standard flexibility. — The highest working pressure. Ps（Kgf/c㎡）— Static working pressure, means at normal temperature, static test conditions, the highest working pressure the hose can endure. Rs（mm）— Static bending radius, means the smallest bending radius the hose can endure during installation. Pb （Kgf/c㎡）— Exploding pressure, means the hose will explode when reaches that pressure, it’s vale is at least 4 times of the normal working pressure. Pt（Kgf/c㎡）— Leakage test pressure under water — it equals 1.5Pd in dynamic applications. — it equals 1.5Ps in static applications.
