IMPROVED END CONNECTOR FOR HIGH PRESSURE REINFORCED RUBBER HOSE

摘要

An improved swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the improved connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20,000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the improved connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the improved device will fail before the connector pops off the hose. The improved connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.
