Pro: A permanent, flexible, and easy-to-install design maintains secure seal despite slope, misalignment, or movement.Ĭon: Greater initial expense than other solutions.Īs a hygienic processor, you work to ensure your plant environment is kept safe, secure, and clean, and the problem of maintaining high standards with piping thatpenetrates through walls needs an effective solution. With this design, there is no need for caulks or sealants, and with a mounted base, the boot will not separate from the wall, floor or ceiling. Installation of flexible boot seals is much easier than escutcheon plates due to a self-sealing base that fastens securely to walls, floors, and ceilings using a pre-drilled stainless steel mounting ring with screws. The elastomer boot also dampens piping vibration and absorbs noise. Unlike a rigid metal escutcheon plate, a flexible design maintains a secure seal around the piping despite pipe slope, misalignment, or movement. The flexible boot can be trimmed to size in the field to maintain an air-tight seal around the piping. Pro: Provides rigid, watertight seal around penetrations.Ĭon: Non-hygienic design precludes their use in food, dairy, beverage, and pharmaceutical environments without additional seal.Īn effective alternative to escutcheon plates is a type of sealing device that incorporates an elastomer boot to seal around the piping. Note: If not allowed to flex slightly, piping is subject to material fatigue and potential failure in joints and connections. This feature is an advantage in some utility, drain, or sewer applications but would create stresses in most process piping installations due to thermal expansion and contraction. Once installed, the rigid design holds the piping securely and doesn’t allow movement. Some designs can offer fire-rated or pressure-rated options, but their non-hygienic design precludes their use in food, dairy, beverage, and pharmaceutical environments without being covered by an external seal designed for sanitary settings. Modular mechanical seals are often used to provide a rigid, watertight seal around pipe penetrations in concrete foundations and structural openings where a hygienic seal is not required.Įach mechanical seal must be assembled using elastomer links, pressure plates, and bolts. The ring slides into the opening and, when tightened, expands to fill the gap. This seal design incorporates a series of elastomer segments or links that are bolted together to form a ring around the penetrant. Pro: Inexpensive, short-term solution that provides decorative trim to penetration.Ĭon: Over time plates will separate from the wall and lose their hygienic seal. Their design can’t compensate for piping misalignment, pipe slope, movement or vibration. Combined with the movement and vibration of process piping, the plate soon separates from the wall, exposes the gap it was meant to cover, and begins to slide down the piping.Īlthough escutcheon plates are relatively inexpensive and may be a short-term solution to covering piping penetrations, they do not provide a hygienic, permanent seal between the piping and the wall or ceiling. They typically remain in position for a brief period until, over time, the caulk or sealant inevitably dries out and loses its adhesive qualities. Most escutcheon plates are installed by applying caulk or sealant to the back of the plate and pressing it against the barrier. They are a common and inexpensive solution for covering gaps, but they have proven to be ineffective for most processing facilities. They temporarily cover the gap in the opening and provide a decorative trim to the penetration.
