Annular Space Seals and Custom Solutions for Your Building entry

Standard solutions for home entries often fall short of expectations or may not align with specific structural conditions. This can also occur when sealing media conduits. To address these specialized needs, Hauff-Technik provides an extensive range of customized solutions, including annular space seals. Designed for maximum adaptability, these seals are perfect for renovating or retrofitting existing media lines.

Casing Pipes and Flanges for Every Application

Custom solutions may be necessary for the renovation or retrofitting of entries in base plates and wall areas. In such cases, a wall breakthrough is often utilized, particularly when there is no empty pipe available for building entry. The key challenge is to ensure a gas- and water-tight seal at these entries in both the base plate and the wall.

Hauff-Technik's custom solutions are versatile and applicable in various scenarios. We offer stainless steel casing pipes with central flanges designed for embedding in concrete, which create an effective waterproof barrier. These stainless steel pipes provide a standardized receptacle for sealing packages. Additionally, we supply fixed and loose flange casing pipes made from stainless steel, which can be secured in multiple ways. Furthermore, we offer a range of solutions for embedding, anchoring, or concreting in walls, ceilings, and floors.

Custom Solutions for Retrofitting Annular Space Seals

In many cases, it becomes necessary to install a supply line into a building at a later date, or existing media lines may need to be sealed. Standard solutions often fall short in these situations. Custom sealing systems utilizing annular space seals are the ideal solution.

Existing supply lines can pose significant challenges for construction companies. Typically, installing an annular space seal requires disconnecting the line. A more efficient approach involves the use of a split flange, which consists of two parts that are placed around the lines before being bolted together. Complementing this, a split annular space seal can be installed over existing lines, enabling retrofitting with minimal effort while ensuring complete gas and water tightness.

Annular space seals with segment ring technology are designed to accommodate multiple media lines, allowing for effective sealing of casing pipes with several supply lines. Furthermore, individual supply lines can remain unused, making it easy to introduce additional supply lines later on. This flexibility makes Hauff-Technik’s solutions both intelligent and future-proof.
