The Flanged Spool Inspection Port Assembly (FS-1), nicknamed the 'spool', is a plug designed for mounting on a tank that is insulated with a polyurethane spray on insulation, without any jacketing. It is a double flanged inspection port that can be mounted to the tank surface using either silicone or mastic and then have the polyurethane sprayed around it. Once the foam hardens, a permanent inspection hole is created, giving a customer a cost-effective solution for future inspections.
The FS-1 can be configured to almost any thickness since Access Plug Flange cuts the sleeve prior to press fitting the flanges to it. Once the flanges have been press-fitted to the sleeve, a permanent solution is created.
The FS-1 comes standard in the 2 1/2", 500 °F configuration, but other configurations can be designed around your needs. Any Access Plug Flange inspection port can be configured to work with this application.
The FS-1 flanged spool inspection port carries Access Plug Flange's technology of the most reliable sealing mechanism on the market today.
