ConCRETE CoRE TEmPERInG REHAU protective sleeve REHAU compressed-air pipe cap REHAU manometer REHAU compressed-air plug nipple Illustration 9-19: REHAU Protective sleeve Illustration 9-20: REHAU Compressed-air pipe cap Illustration 9-21: REHAU Manometer Illustration 9-22: REHAU Compressed-air plug nipple The REHAU protective sleeve made of polyethylene is used for expansion joints. It can also be used for leading connection lines through from the concrete ceiling to above the ceiling. The REHAU compressed-air pipe cap is used for pressure tests at the construction site and is assembled to the REHAU BKT modules with the REHAU compression sleeve joint at the factory. With the REHAU concrete core temperature control installed on site, it is assembled by the customer. The REHAU manometer is used in conjunction with the REHAU compressed-air plug nipple during pressure test at the construction site. The pressure tests are to be performed before concreting and after inspection of the lower boarding level at the construction site.
