11.2 Installation instructions for DN 600 - DN 1000 BLS ® joints Applicability DN 00 - DN 1000 BLS ® joints These installation instructions apply to ductile cast iron pipes and fittings with longitudinal force-fit BLS ® restrained joints. Where appropriate the installation instructions for pipes with cement mortar coatings (ZMU) should be followed. In the case of buried pipelines, the number of joints to be locked has to be decided in accordance with DVGW Arbeitsblatt GW 3 8. The permitted tractive forces for trenchless installation techniques are laid down in DVGW Arbeitsblätter GW 321, 322-1, 323 and 32 (draft), or see section 2, page 20, Table 2.1.

Installation instructions Cleaning The locking segments and those surfaces of the seating for the gasket, the retaining groove and the locking chamber which are indicated by arrows should be cleaned and any build-ups of paint should be removed. A scraper, e.g. a bent screwdriver, should be used to clean the retaining grooves. Clean the inserting end. Assembling the joint Fitting the TYTON ® gasket (see pp. 10 -107) The opening in the end-face of the socket should always be positioned at the crown of the pipe. Use the laying tool to push the inserting end of the pipe into the socket of the pipe which is already in place until it is in abutment. 11
