Abstract

The invention discloses an elastic bulkhead penetration piece for a high-temperature pipeline, and belongs to the technical field of pipeline vibration noise control. The bulkhead penetration piece comprises a welding flange, an inner pipe, a metal corrugated pipe and a threaded flange, the outer circumference of the inner pipe is provided with two radial limiting bosses, a threaded section is machined at the position, at one end, of the outer circumference, and the threaded section starts from the end face of the inner pipe and ends on the step faces of the limiting bosses; the appearance of the metal corrugated pipe is of a spindle-shaped structure, and the inner circumference and the outer circumference of the position where the diameter is maximum are of a plane structure; the two ends of the metal corrugated pipe are welded to the opposite step faces of the two limiting bosses of the inner pipe, one end of the inner pipe is welded to the welding flange, the other end of the inner pipe is connected with the threaded flange through threads, and the position, where the diameter is maximum, of the metal corrugated pipe is welded to a through hole of a bulkhead. The elastic bulkhead piece can solve the vibration isolation problem of bulkhead penetration of the high-temperature pipeline, and meanwhile the requirements for strength, sealing performance, reliability and the like of the bulkhead can be met.

Description

technical field [0001] The invention relates to a marine pipeline accessory, in particular to an elastic penetrating part applied in the field of shipbuilding, and belongs to the technical field of pipeline vibration and noise control. Background technique [0002] For large ships, there are a large number of high-temperature and high-pressure pipelines in the system pipeline. When the pipeline passes through the bulkhead, deck or tank, in order to maintain the strength, sealing, high-temperature and high-pressure resistance of the bulkhead and the maintainability of the pipeline, usually The way of penetrating cabin parts is adopted. Due to the high-temperature characteristics of high-temperature and high-pressure pipelines, the heat aging speed of ordinary damping materials is accelerated at this temperature, and the strength drops sharply, which cannot meet the requirements of high-temperature characteristics. On the wall, the two ends of the penetrating piece are connec...
