A large pharmaceutical customer maintain the integrity of their water loop by replacing standard orifice gaskets with Holland Sanitary Orifices. The standard orifice gaskets provided by gasket manufacturers are typically molded over a flat stainless steel disc with the orifice size drilled as needed.

The problem stems from separation of the elastomer from the stainless steel orifice disc.  This customer was finding rapid deterioration of the bond.  During cleaning and SIP cycles the gasket material can separate from the stainless disc creating entrapment leading to microbial growth.  The two dissimilar materials; the elastomer and the stainless steel disc expand and contract at different rates during temperature changes causing deformation and separation.This area of separation is virtually impossible to clean.

The Holland Sanitary Orifice is a cleaner solution to this problem.  They are machined from solid stainless steel and are fully drainable in the Vertical position.  They are also available in eccentric designs for horizontal installation.
