Wall sealing Alflow sells wall-sealing systems for the food, pharmaceutical and chemical industries. The wall-sealing systems are used to seal a sanitary pipe penetration in ceiling, floor or wall, so that it is easy to clean and no bacteria can accumulate. See the selection of wall-sealing systems from leading manufacturers on this site, and transport the particular liquids in the best possible way. What is wall-sealing? Our wall sealing forms a flexible and hygienic seal that allows piping to move without breaking the seal. The wall sealing is made of a flexible material that allows certain movement, so that e.g., vibrations and longitudinal movements of the piping does not affect the tightness in any way. With its unique silicone sealing ring under the stainless-steel flange, the wall sealing forms a close seal to the substrate. At the same time, the sheath itself is also made of silicone, so it fits completely close to the pipe, without the use of sealant or any other type of seal, which makes the system quick and easy to install. Installation of our wall-sealing systems is just as simple - the screw holes are pre-drilled and clear cutting rings indicate where to cut. The wall-sealing system helps keep process areas isolated from the surrounding space. The airtight seal keeps water, dirt, mould and dust out and can be easily adapted to most pipe types and pipe diameters. Find the right wall sealing for your application The wall-sealing system is made of hygienic silicone in accordance with the FDA. Silicone is durable and resistant to extreme temperatures and water. Even after extensive tests equivalent to 158 years of outdoor use, the wall-sealing system remains waterproof and shows no signs of degradation. The wall sealing can withstand high flushing pressure, e.g. when cleaning with a high-pressure cleaner, and they are durable at temperatures from -50 to + 250°C. The wall sealing is flexible and can be supplied for pipe sizes from 1 to 355mm. The range of wall sealing includes: • Pipe-to-pipe for sealing pipe-to-pipe • Standard wall sealing for sealing wall, floor and pipe penetrations • Grooved cable gland for installation in cut out holes • Reboot cable gland for installation on existing installations • Multi-lead-through for sealing, e.g., cable glands Reboot wall sealing is a universal, moveable silicone pass-through system for existing tubing. This seal is fitted to existing installations by simply mounting it around the pipe, and closing it with small clamps, ensuring that the installation is completely tight.
