Foam in Place Testing & Inspection Port

Our customer had a need for an inspection port to be mounted on a tank that was insulated with a polyurethane spray on insulation without any jacketing. APF designed what we call the Flanged Spool Inspection Port Assembly (FS-1), nicknamed the 'spool'. 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 was created giving the customer a cost-effective solution for future inspections.

The FS-1 can be configured to almost any thickness since we cut 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.
