摘要： 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.

摘要： One aspect of the invention provides an elastomeric bushing including: a plurality of rigid members defining one or more internal annular ribs and one or more elastic members. The rigid members include: a first internal annular rib adapted and configured to engage a corrugation valley of corrugated tubing; and one or more trailing lips adapted and configured to extend through a central opening of a nut and engage said nut, thereby preventing axial movement of the bushing when a corrugated tubing is advancing through the bushing. The one or more elastic members are adapted and configured to: hold the plurality of rigid members in a substantially annular configuration; allow the plurality of rigid members to expand to allow a corrugation peak to pass under the first internal rib; and hold the plurality of rigid members against the corrugated tubing so that the first internal rib lies within a corrugation valley.

摘要： A coupler assembly (10) and method of manufacture (10) for use with pipe comprising a unitary annular body (20) forming first and second cylindrical openings for surrounding a pipe or piping sections to facilitate forming a fluid-tight seal therein. The unitary annular body (20) comprises a medial portion (64) formed from a first material having a first durometer and first and second lateral portions (56, 58) integrally connected to opposite ends of the medial portion (64). The first and second lateral portions (56, 58) are made from a second material having a second durometer relatively higher than the first durometer of the first material. The coupler assembly (10) further comprises at least one clamping assembly (26) surrounding the unitary annular body member (20) adapted for compressing the coupler assembly (10) into a fluid-tight seal.

摘要： A joint device for a corrugated pipe. A socket pipe in which a packing is forcedly inserted is joined to a non-corrugated part of the corrugated pipe and the non-corrugated part is expanded at the position of the packing. The joint device has a guide groove formed on the outer circumference of the socket pipe, a connector fit to the socket pipe, and a movable bolt screw-coupled to the outer face of the socket pipe and forcedly joined to the guide groove, so as to freely rotate the connector independently from the corrugated pipe.
