Problems solved by technology

[0005] However, fully referring to the installation accuracy control method of DN550 metal flexible pipes in previous products, the pipeline needs to be welded and machined many times, which will increase the risk of flaw detection repair and machining accuracy control, and the DN650 metal flexible pipe cannot be guaranteed. The installation accuracy of the connecting pipe increases the construction cost, the construction period becomes longer, and the product quality is very unstable

Abstract

The invention provides a method for controlling the mounting size of a DN650 metal flexible connecting pipe. The method is suitable for controlling the mounting precision of an ultra-large-diameter metal flexible connecting pipe, and the mounting quality of the metal flexible connecting pipe is ensured. According to the method, the advantages of a traditional method are absorbed, a DN650 mounting precision control process method is provided through scientific analysis and experimental research, so that the pipeline mounting quality of a circulating water system is effectively improved, a scientific, reasonable and efficient process method is provided through experimental research, each construction link is precisely controlled, the construction efficiency and the construction quality are improved, the welding shortening amount of a stainless steel pipeline is obtained through a welding test, and the pipeline manufacturing precision is effectively improved. The method is suitable for being popularized and applied as the method for controlling the mounting size of the DN650 metal flexible connecting pipe.

Description

technical field [0001] The invention relates to the installation of large-diameter metal flexible joints in the field of ships, in particular to a method for controlling the installation size of DN650 metal flexible joints. Background technique [0002] Flexible connection is also called flexible connection and flexible connection. It is a connection method that allows the connection part to undergo axial expansion and contraction, and a certain amount of displacement in the vertical axis. The connection method adopts elastic joints such as rubber joints, corrugated pipes, pipe fittings with special structures and flexible packing. It isolates vibration, reduces noise, and can prevent displacement from damaging pipelines and adjust installation errors. [0003] Flexible connections are usually divided into three types of connectors: vacuum rubber tubes, plastic tubes and metal tubes. Among them, vacuum rubber tubes are mostly used for pipeline connections with a diameter l...
