Funktionsbeschreibung
Movements are concurrent.

Werkstoffe
Merkmale
Patented penetration seal design
(U.S. patent 7478839).
Unlimited axial movement.
Floating ring design permits lateral
movement without introducing high stresses
into the penetration pipe and boiler wall.
Insulated
Sealing efficiency is augmented, rather than
reduced, by particulate build-up:
maintenance between shutdowns is
minimized.
Maintenance and seal replacements can be
performed without cutting pipe or welding.
Robust design limits replacement parts to
stainless steel wire mesh seals and
insulation.

Case pipe: A53B, A106B, 10 mm (0.375”)
Flange ring: A516-70, 12 mm (0.5”)
Inner ring: A516-70, 12 mm (0.5”)
Sliding ring: A516-70, 38 mm (1.5”)
Inner seal: Braid hose with stainless steel
filler
Outer seal: Braid hose with stainless steel
filler

PSS penetration slider seals are used to reduce
heat loss and gas seepage at points where
pipes penetrate a boiler wall. They permit
unlimited axial movement and can be easily
maintained.
