How to Seal Floor/Ceiling Penetrations
在所有加工设施中，员工和产品安全都是最重要的问题。在维护安全处理环境方面的主要组件是控制处理区域内和周围的条件。
楼层的未密封差距and ceilings become pathways that allow airborne particles, moisture, and pests to escape from one area to another where they can contaminate product and create health hazards for employees.
密封渗透的重要性
Sealing all penetrations in a process setting is an important step in producing a safe product and maintaining a healthy work environment. In this post, we focus on floor barriers and penetrations.

实用渗透的考虑因素
为结构的公用事业创建的渗透 - 加热，通风，空调，电气和管道夹具 - 也需要密封to prevent contamination and to preserve the integrity of each space’s fire ratings。Perhaps less evident than when sealing wall penetrations, floor/ceiling penetrations often pass between spaces of widely variable uses and temperatures — and therefore fire ratings. Usingflexible boot sealshelps to maintain rating integrity by protecting fire-rated sealants and insulation from wear and damage.
Electrical lines and air-hoses可以密封, as can plumbing piping, electrical conduit and virtually any other penetrant that must traverse a floor/ceiling barrier.
Sealing of plumbing and sprinkler systems
工厂运营商合理地专注于food在思考密封渗透时的加工设施，但是管道和喷水灭火系统的渗透同样重要。
药物加工中的细菌，灰尘和制造残留物 - 它们的行为与空气和水相同，所以始终寻求阻力最小的路径。That’s why all penetrations should be sealed- 无论是处理系统的一部分还是由管道，加热或喷水灭火系统创建。
户外应用
在室外且不断暴露于元件的渗透性很少需要卫生，但它们仍然需要正确地密封以承受暴露于紫外线和极端温度的变化。Silicone boots紫外线稳定，其温度范围为-40°至500°F, which makes them less susceptible to degradation.
审美差异
由于高放置（天花板）或其在清洁（地板）期间的情况下，地板/天花板渗透比墙壁穿透更明显。是因为，美学经常在楼层和天花板的密封剂设计中发挥作用。例如，工业资产管理理事会(IAMC) and theSociety of Industrial and Office Realtors（SIOR），名称植物设计和美学作为未来肉类加工厂的基本因素。
Food processing plants of all kinds are more than businesses--they represent social relationships with employees and their communities and therefore have contributions to make to a larger regional identity (Moline, 2015).Silicone boots are by far the neatest, most attractive option available。
Therefore, plants that take pains to keep processing facilities polished without paying attention to penetration seals risk undermining the integrity of their efforts. As the following images show, the choice of penetration seal can make a significant difference in plant aesthetics.
Securing flexible boots to floors and ceilings
Boot rings secure flexible boots to floors and ceilings to stabilize the penetrant and maintain the seal in concrete and metal or to ceiling or floor tiles of various materials.
Auditing Your System to Seal Penetrations
为了保持高卫生标准，必须常规审核系统并确保所有渗透都是密封的。通过花时间来审查您的环境，不仅您可以提高美学的外观和感觉，但您还可以保证员工的安全和产品完整性。
What to Review
开孔和部分密封的孔可以产生和转移污染物。
Flexible boots create seals that prohibit transfer of contaminants.
橡胶靴和密封件和金属环都没有产生任何残留物，因此它们比密封技术更有效，具有允许渗漏或促进自己的污染物的潜力。当无挡裂缝填缝干燥并突破时，它从成为作为问题的一部分的解决方案的一部分发生变化。
Old or damaged insulation similarly contaminates spaces with dust and particulates.
Avoid utilizing putties, sealants, & caulks on existing pipe
While the pipes below appear to be sealed, water and vibration eventually turn unprotected seals to dust.
Use重启硅胶靴的风格，正确密封现有管道
Boots can be cut to the correct diameter and wrapped around pipes. In addition to adhesive seals, the rings can be secured to ceiling materials with screws.
Gravity works against floor/ceiling sealants by pulling escutcheon plates away from penetrations.
锚定密封件不易受重力的力量。
Don't omit sealing plumbing lines in areas that must remain sanitary.
Omitting plumbing lines from a sealing audit can permit contaminants to travel throughout a plant.
Seal all penetrations in sanitary rooms.
Two features of silicone boots for existing piping ensure a tight fit: horizontal cut lines for matching pipe diameters, and metal staples that slide over the seam for crimping.
Flexible sealing boots解决了围绕现有管道密封的挑战。The pliable silicone boot has a split that allows installers to wrap the boot around the piping。分裂接缝的两个加强侧由硅氧烷弹性体制成，其可以与不锈钢钉卷曲一起卷曲。结果是永久性的卫生压缩密封，不会裂开或分开时间。
Modular mechanical seal assemblies can be installed into existing piping penetrations but should only be used in areas that do not require a hygienic design.
Tube-in-Tube Transitions
Floor penetrations often incorporate a section of pipe or sanitary tube in the opening as a sleeve to protect the process piping running through it.套筒经常用作踢腿，并给出工艺管道足够的空间以在不受限制的情况下移动和振动。
必须密封套筒（外管）和工艺管道（内管）之间的间隙以防止碎屑从上方落入其中。用于该应用的管管密封必须完全密封间隙并允许内管根据需要移动和振动。
The rigid design of metal escutcheon plates makes them ineffective as tube-in-tube sealing devices.
消防额定应用
可燃油，爆炸性粉尘和易燃液体和气体只是许多食品和制药设施中的一些火灾危险。Processing environments that contain potential threats to fire safety may require penetrations with some level of passive firestop for delaying or preventing fire from passing through the penetration. Requirements for a proper penetration firestop are addressed in numerous standards and codes:
- 承销商的实验室UL 1479
- ASTM E814
- NFPA 101 and NFPA 70
- Life Safety Code
- National Electrical Code
- International Building Code
Most of the current standards require more than simply filling an opening with a firestop sealant. They also require a complete system made up of a fire-rated barrier, the penetrating material, and the firestop sealing agent.
Fire codes for your facility are locally developed and enforced, so联系您当地的消防元帅或建筑码检查员，了解您的设施是否需要逃避系统。
几种产品地址用于各种类型的穿透的FireStop应用，从完整的多组分密封系统到膨胀（热扩展）密封剂和枕头到玻璃纤维或矿棉包装。为您的食品，乳制品，饮料或药物穿透选择遗漏方法，可提供适当的防火和卫生密封以保护您的卫生环境。
Stainless steel escutcheon plates are not fire-rated and they don’t provide hygienic seals around penetrants, so they are not the right choice for a fire-rated penetration application in sanitary environments.
柔性硅胶靴子不防火等级themselves, but they properly seal penetrations that have been filled with one or more firestop insulating products. The fire-rated material inside the penetration gap is effectively sealed off from any exposure to your sanitary environment with a high-grade hygienic silicone seal that is temperature rated up to 500°F.
Next Steps
作为卫生处理机，您努力确保您的植物环境保持安全，安全和清洁，以及通过楼层和天花板支付管道的高标准的问题需要有效的解决方案。
