Disconnecting BLS ® joint disconnection Push the pipe into the socket in the axial direction until it is in abutment and take out the locking segments through the opening in the socket. Laying equipment and aids The following items of laying equipment and aids are available for assembling joints and fittings Laying equipment: DN Pipes Fittings 80 MMA, MMB, MMR 100 Lever and flanged so- Socket-bend: laying tool (e.g. V 301) 12 80 100 ckets: Lever 12 1 0 Laying tool V 301 200 2 0 300 (3 0) 00 00 00 V 301 V 302 (ZMU) V 302 + chain-equipped fork tool of V 301 700 800 900 1000 Rack assembly Rack assembly Aids: Dusting brush, cotton waste, wire brush, spatula, scraper (e.g. bent screwdriver), paint brush, lubricant, tracer. 121
Installation instructions 11.3 Installation instructions for ductile cast iron pipes with cement mortar coatings (ZMU) Applicability These installation instructions apply to the installation of ductile cast iron pipes to DIN EN with cement mortar coatings (ZMU) to DIN 1 2. To make the joints, the installation instructions which apply in the respective cases should be followed. What also apply are the guidelines given in DIN EN 80 and DVGW Arbeitsblatt GW 00-2 (for water pipelines) or DIN EN 10 and ATV-DVWK A 138 (for waste water pipelines). Installation Installation must be carried out in such a way that the ZMU is not damaged. The following options are available for protecting the restrained joints • a cement mortar protecting sleeve • shrink-on material or protective tapes (to DIN 30 72), • a mortar bandage (e.g. as produced by Messrs. Ergelit) for special applications. Cement mortar protecting sleeves Cement mortar protecting sleeves can be used on TYTON ® and BRS ® restrained joints up to DN 700 and on BLS ® restrained joints up to DN 00. Before the joint is assembled, the sleeve is rolled on and, with the larger diameter leading, is pulled onto the inserting end sufficiently far for the ZMU to project by approx. 100 millimetres. Fitting can be simplified by applying lubricant to the ZMU. Once the joint has been assembled and the seating of the gasket checked with the tracer, the sleeve is folded over, pulled to the end-face of the socket and rolled over the socket. It then rests firmly and closely in place. 122
