Safe-T-Sponges® are available with or without laminate in various sizes.
Irregular shapes and sizes can be made from emailed prints.
PL-2 attached to ADV-67 lanyard protect this flange opening. Our lanyards are high strength with stainless steel carabiners at each end. Available in standard 6’ and custom lengths they allow quick and strong attachment and removal of Safe-T-Sponges ®. Lanyard attachment is standard ‘best practice’ in nuclear applications and gaining acceptance during fossil outages.
Laminated Safe-T-Sponges® like this L-PL-8 offer extra heat resistance if needed.
LE (Laminated Enclosed) Sponges are covered on all sides with laminate offering improved durability.
PL-2s protect fossil boiler tubes during and after weld prepping. Safe-T-Sponges ® were originally developed for boiler tube repair and replace hand made ‘gags’. Supplied standard with ID tags or available with RFID technology QC managers and Superintendants can provide controlled, high quality, low cost debris control during outages. X-Ray visible, flame resistant, protected by flame retardant high visibility white laminate and proven during hundreds of outages. Safe-T-Sponges ® are the standard for boiler tube F.M.E.
Large diameter ‘doughnut’ sponge surrounds a PL-6. Doughnut sponges allow quick F.M.E. on piping that surrounds a smaller, interior pipe. This is one of many ‘specials’ manufactured by Advanced F.M.E. Products.
