Installation quality control of central heating metering systems for newly built residences

With the commonly used design mode of newly built residences, taking the installation of some concrete heat metering heating systems as examples, presents the relevant aspects of the installation quality control, including the construction drawings reviewing, the incoming inspection and storage of materials to be used, the installation of main heating equipment, the preparation and clearing of the ground trench, the laying method and technical specification of directly buried piping, the connecting method and quality control of galvanized piping and plastic piping, the concealing method and requirement of buried plastic piping, the pressure testing and cleaning of buried plastic piping and heating system, and the thermal regulating method and requirement of the heating system. Emphasizes the installation quality control and bending quality control of piping during construction and the commissioning after completion. Analyses the main issues existed in installation procedure and proposes some solutions.
