Small-diameter piping, thermal instrument layout and positioning of support and hanger design take fully into account the expansion space and insulation thickness. Large-diameter pipes after heat preservation plastering construction of valves, turbine, checking smooth surface, high temperature powder paint fully dry after. Protective coverings for electric equipment insulation boards designed with pressure plate, when ordering according to the installation diagram, model specifications publishing order, ensure when installing corners neat, uniform appearance, reduce the amount of on-site machining. Before valves, flange insulation shell construction, be sure to make a unified model, all valves, flanges, insulation cover unified, tidy and beautiful. When four parts such as pipes, boiler insulation, must do first article inspection, proof of design and construction methods, technology can meet the technological requirements, before extensive construction. Boiler steel beams, door opening boxes designed with insulation gaskets, flange cannot be oblique, even fastened. Back into the slope of the tubing during ins
