Control valve instrumentation engineering

Contact and division of labor with other installation works. Described below.
1 meter time to take the source component installation, completion of the construction unit should be installed by the process and pipeline. Process piping manufactured or prefabricated, installed at the same time to complete the installation. For example, take the openings of the source component and welding should be completed before the process piping or equipment corrosion lining, purge, pressure testing; high-pressure steel, alloy steel, non-ferrous metal pipe to take the source components should be used machining methods; furnace installation and other masonry or concrete pouring on to take the source components should be buried in the masonry or cast. Take the source valve should be installed after passing inspection, and should not be used sleeve type connection.
2 installed directly in the process piping instrumentation, such as orifice, rotameter, control valves, pipeline installation and construction units should be in the purge of the process piping and pressure test before installation. If you need to process piping installed at the same time, you should purge process piping, pipeline installation and construction units will remove the instrument, and install short tube, after the completion of the purge these instruments installed by the pipeline installation and construction units.
Control valve the measurement orifice Automation Instrumentation required for installation support, base or boom should be pipeline installation and construction units to complete the installation o. Maintenance of instrumentation and automation equipment required operating platform, connecting channels and other components from the installation and construction equipment and piping installation and construction units.
