AN IMPROVED PROCESS FOR MANUFACTURING A HOT REHEAT SYSTEM STRAINER HOUSING TO HOLD A STEAM STRAINER FOR CARRYING STEAM BOILER TO IP TURBINE.

摘要

The invention relates to a HRH steam strainer housing (1) is connected between HRH steam pipe and an interceptor valve. A HRH steam strainer (10) is welded over a blanking device (2) of the housing and then it is uplifted by an assembly device inside the strainer housing. When the strainer gets fixed inside the hosing, a graphite gasket (3) is inserted into the housing after which a protective ring (4) is inserted. A segmental split ring (5) is inserted in a slot available in the housing. This segmental split ring protects the elements (2, 3 and 4) from falling. A tightening cover (6) is inserted into which studs (7), washer (8) and nuts (9) are tighten for final assembly. Each item is assembled in such a way that the housing is safe in operation. A drain stub is provided to drain the condensed steam from Strainer Housing.
