Abstract

The invention discloses a low pressure pipeline mounting process used in a 300m<2> sintering low temperature waste heat power generation system. The mounting process comprises the following steps of manufacturing pipes, pipe fittings as well as elbows, supports and hangers in configuration of pipeline accessories; mounting pipeline welding positions in mounting of the pipelines, middle and low pressure pipelines, drain and blow off pipes, valves, flanges, the supports and hangers; assembling welding joints, testing a pipeline system, and cleaning the pipeline system. The process can be suitable for the pipeline paving in the 300m<2> sintering machine low temperature waste heat power generation system by orderly mounting the pipelines, so the power generation efficiency is ensured, and the problem that the existing mounting process cannot meet the pipeline paving demands in the 300m<2> sintering machine low temperature waste heat power generation system.

Description

technical field [0001] The invention relates to the field of electromechanical installation, in particular to a 300m 2 Low-pressure piping installation process in sintering low-temperature waste heat power generation system. Background technique [0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants. It is the main equipment in the draft sintering process. It can sinter concentrate powder and rich mineral powder with different components and particle sizes into blocks, and partially eliminate the sulfur contained in the ore. , phosphorus and other harmful impurities. The sintering machine is divided into several specifications of different lengths and different widths according to the sintering area. Users can choose according to their output or site conditions. The larger the sintering area, the higher the output. The sintering machine is not a machine, but a project consisting of several processes. Wit...
