CI Y type strainer and CI T type strainers are the important parts of piping systems to guard equipment against possible damage due to the trash and other particles which may get carried by the fluid. During the time of system start-up and flushing, the Strainers may be installed upstream of pumps to guard them against construction trashes, that may be left in the pipes. Permanent Strainers are installed at upstream of traps or control valves to protect them from corrosion products.
