Laying instructions for ductile cast iron pressure pipes, fittings and valves, equipped with thrust-resisting joint Novo SIT 2286 ® General instructions For laying pressure pipes, fittings and valves with thrust resisting joint Novo SIT ® “laying instructions for ductile cast iron pressure pipes and fittings with TYTON ® -joint” should be observed. Application field Novo SIT ® -locking rings are available for dimensions DN 80 up to DN 1000 and for nominal pressures up to DN 80 — 300 25 bar (on request up to 40 bar) DN 350 — 600 16 bar (on request up to 25 bar) DN 700 — 800 10 bar (on request up to 16 bar) This self-anchoring, thrust resisting socket joint substitutes concrete anchoring blocks. The suitable number of thrust resisting connections has been laid down in DVGW standard GW 368 and has to be observed. Before installation in lines for bridges, ducts or river-crossings, please contact our service team. Figure: Novo SIT ® -ring with vulcanised segments made of chromium steel.

6 Laying 230 instructions for ductile cast iron pressure pipes, fittings and valves, equipped with thrust-resisting joint Novo SIT ® 1. Cleaning inside the socket, particularly the TYTON ® -groove. 2. Insert gasket (TYTON ® -ring) by deflecting and squeezing, so that the gasket is firmly bedded in its seating. The inner part of the inserted TYTON ® -ring should be slightly lubricated. 3. Insert Novo SIT ® -ring into the pre-chamber. 4. Cleaning of spigot-end, slightly lubricate and insert concentrically into the socket until it touches the TYTON ® -ring. 5. Suitable tackles to push the spigot evenly into the socket have to be employed, f.e. laying tool V 300 D acc. to the illustration. Deviation should be avoided. Important: Changes of circumferential directions have to be arranged before connecting (f.e. installation of outlets, tees a.s.o.). Laying device V 300 D Alternately moving of levers draws spigot into the socket Locking Attention: After connecting both parts, the locking of the segments has to be accomplished by moving the levers in the opposite direction. The exact position of the TYTON ® -ring has to be tested with suitable gauge between the segments on the whole circumference. Gauge Note: Deviation of the installed thrust resisting joint is possible as follows: up to DN 400 – 3 ° up to DN 700 – 2 ° up to DN 800 – 1 ° A pipe with 6 m length and 1° deflection deviates approx. 10 cm off the neutral pipe axis. Dismantling of thrust resisting joints Segment marking dots Push the spigot completely into the socket. Adjust dismantling blade to the outside diameter of the spigot, insert the blade into the hammering device, lubricate the blade slightly on both sides and drive the blades on all segments marking dots into the socket. Use pipe laying tool or dismantling collar to remove the sections from each other. Plates 6231
