Abstract
A hose and rigid pipe connecting system used in a high pressure system comprises: a hose made up of connecting a core pipe and a corrugated pipe, the outer side of the corrugated pipe being wound and woven by metal wires; a rigid pipe; a transition joint connecting the hose and the rigid pipe; and a retaining ring buckled on the outer side of the hose and the transition joint. The invention has the advantages that the sealing performance between the hose and the rigid pipe can be greatly improved, and the problem that the connecting part of the hose and the rigid pipe can not bear pressure Or resist high and low temperatures is solved; besides, the axial tensile strength and sealing reliability are improved by winding and weaving metal wires on the outer side of the metal corrugated pipe and then welding with the core pipe.
