DEVICE FOR CONNECTING PIPES, A HIGH PRESSURE FLUID CONDUIT SYSTEM OF A DUAL FUEL ENGINE, DUAL FUEL ENGINE AND USE OF A TIE NUT

摘要

A pipe connection arrangement in a high-pressure fluid line system of a dual fuel engine, having first pipe element with outer sealing cone and conical shoulder adjoining the cone, having further pipe element with inner sealing cone and external thread, having a screw nut element with clamping sleeve region having inner clamping cone and threaded sleeve region having internal thread. The outer sealing cone of the first pipe element is arranged in the inner sealing cone of the further pipe element and the internal thread of the screw nut element is screwed on the external thread of the further pipe element. The inner clamping cone of the screw nut element is pulled against the conical shoulder of the first pipe element such that the outer and inner sealing cones are clamped with one another in a sealing manner, wherein the threaded sleeve region of the screw nut element is conical.
