Upper Housing
Installation
NOTE
These are torque values for RTW remote seals.
This is not the torque specification for the lower housing onto the process
threaded connection. Standard NPT torque values for the size threads in the
lower housing should be applied here.
Gasket Installation
Threaded seals with flushing connection rings come with a sealing gasket.
When connecting the remote seal, gasket, and flushing connection ring make
sure the gasket is properly aligned on the gasket sealing surface.
Alternative System
Installation Procedure
An alternative to threading the entire seal system assembly to the process
piping is to unbolt the seal upper and lower housing and thread the lower
housing to the hard piping separately. Bolt the upper and lower housings
together to the required torque specification.
Note that gaskets need to be replaced once they have been torqued. Thus
this alternative system installation procedure requires gasket replacement.
WSP SADDLE TYPE
SEALS
NOTE
For detailed manufacturing procedures designed to guide an operator through
performing alignment and welds at the connections for a flow-through seal
series, contact your local Emerson Process Management representative.
