Installation can be divided into sub-projects, the division of engineering and engineering units. Sub-project is based on use, type of transmission does not With the media and materials, and equipment category are projects. For example, water supply installations, drainage installation, installation of power transformer Engineering, instrument panel installation, the temperature instrumentation installation works. Division project is divided according to type of installation works, cases of Such as the piping installation, electrical installation, automatic installation of instrumentation, process furnace installation works. Unit works A unit project. For example, industrial buildings, a factory installation project is a unit of engineering, plant outside the region to Water, drainage, heat and gas pipeline installation is a unit works. Multi-unit project or sub-division of engineering project Composition. Installation of industrial automation instruments, also known as instrumentation engineering. Instrument works shall be in accordance with the design and construction drawings and instrument installation manual provisions and other provisions of the relevant standards. Modify the design must be approved by the original design unit agreement. Instrument Engineering and other associated installation work and division of labor. Described below. 1. Instrument time to take the source components, installation, by the process and the completion of pipeline installation and construction units. Should be manufactured or prefabricated process piping installation at the same time to complete the installation. For example, take the source components of the hole and the soldering process piping or equipment shall be corrosion, linings, purging and pressure testing before its completion; high pressure, steel, nonferrous metal pipe should be used to take the source components machining methods; the furnace such as masonry or concrete pouring will take a body installed on the source component should be buried in masonry or the pouring of people at the same time. Take the source valve should be installed after passing inspection, and not suitable sleeve type connections. 2. Directly installed on the process piping on the instrument, such as orifice, rotor flowmeter, control valve, pipe installation and construction units should be in process piping purge and post-installed before the pressure tests. If you need to be installed with the process piping should be in the process pipe purge, by the pipe installation and construction units will be removed meter and install a short tube, purge after the completion of pipeline installation and construction units by the installation of these meters. 3. Control valves, measuring instruments and other automated plate to install the required support, the base or the boom by the pipe installation and construction units to complete the installation o. Instrumentation and automation equipment needed to maintain the operating platform, connecting channels and other components from the equipment and pipe installation construction unit installation and construction. 4. Instrumentation, automation equipment and pipe insulation insulation installation and construction works by the construction unit. 5. Instrumentation, automation equipment, insulation, heat and emissions associated with mains pipeline project, instrument use compressed air, hydraulic mains pipeline installation and construction works by pipeline installation and construction units. 6. Instrumentation, automation equipment and auxiliary equipment connected pipelines, insulation, heat and emissions from pipeline with branch pipe from the meter installation project installation and construction units facilities. 7. Special meter has been installed by a professional install the unit installation and construction. For example, analytical instruments, with the introduction of auxiliary equipment, the installation of a dedicated instrument designated by the manufacturer of professional installation unit installation and construction. 8. If you are not specified in the design of instrumentation and automation equipment, installation, construction units should be determined in consultation with the general contractors to construction units and division of labor.
