Abstract

The invention provides an off-line assembling and quick installing method for pipelines of a confined space, and aims at reducing the confined space pipeline installing and welding difficulty, changing a conventional technological procedure, shortening the construction period and improving the production efficiency. The method is characterized by comprising the steps that 1, the pipeline installing positions, varieties, number and areas are determined according to a pipeline installing drawing; 2, the pipelines in the confined space are manufactured into a frame type pipe network according to relevant data in a manufacturing field; 3, the frame type pipe network is installed on corresponding parts by being divided into a plurality of portions or integrally installed on the corresponding parts before a structure or a platform or equipment is hoisted; 4, the equipment with the frame type pipe network is installed in position; and 5, the tail-end pipeline of the frame type pipe network is connected with a medium pipeline. According to the new technology, the construction procedure that the pipelines are prefabricated and assembled in advance and then assembled on the equipment in an off-line mode to be installed together with the equipment is adopted, therefore, the construction time in the confined space is correspondingly shortened, and the quality and the installing precision are improved.

Description

technical field

[0001] The invention relates to the technical field of pipeline installation, in particular to a quick installation method for off-line assembly of pipelines in a confined space. Background technique

[0002] In industrial pipeline installation work, the difficulty of pipeline installation in some confined spaces lies in the limited space and narrow working interface. During construction, after the previous process is generally completed, the materials are transported, installed and welded on site within a limited space; or at the manufacturing site, after welding some components, the components are transported to the installation site for follow-up work. Due to the limited space for construction, the installation work is more difficult, the work efficiency is reduced, the welding quality of the pipeline is relatively poor, and corresponding follow-up quality hidden dangers are generated.
