Laying instructions for ductile cast iron pressure pipes, fittings and valves, equipped with thrust-resisting joint Tyton SIT 2326 ® General instructions For laying pressure pipes, fittings and valves with thrust resisting joint Tyton SIT ® “laying instructions for ductile cast iron pressure pipes and fittings with TYTON ® -joint” should be observed. Figure: After cleaning, the Tyton SIT ® thrust-resisting ring ( with segments ) has to be deformed acc. to the illustration an inserted into the socket. Application field: Tyton SIT ® -locking rings are available for dimensions DN 80 up to DN 400 Ductile cast iron pipes with wall thickness k 10 and more. DN 80 — 200 16 bar DN 250 — 400 10 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. Assembling steps 1. Cleaning inside the socket, particularly the TYTON ® -groove. 2. Tyton SIT ® -ring has to be cleaned, deformed acc. to the illustration and inserted into the socket. Ensure that the S-bend is located between two segments during deformation. The inner part of the inserted Tyton SIT ® -ring should be slightly lubricated. 3. Cleaning of spigot-end, slightly lubricate and insert concentrically into the socket until it touches the Tyton SIT ® -ring. 4. Laying tool V 300 D has to be mounted acc. to the illustration, so that both parts can be pushed together ( see page 230 ). Deviation should be avoided! 6233
Laying instructions for ductile cast iron pressure pipes, fittings and valves, equipped with thrust-resisting joint Tyton SIT 2346 ® 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 SIT ® -ring has to be tested with suitable gauge between segments on the whole circumference. Gauge Note: Deviation of the installed thrust resisting joint is possible up to 3°. A pipe with 6 m length and 1° deflection deviates approx. 10 cm off the neutral pipe axis. Dismantling of thrust-resisting joints 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 around the whole circumference into the socket. Use pipe laying tool of dismantling collar to remove the sections from each other. In case the blades can not be inserted properly on whole circumference the line has to be cut. Marking of the installed thrust-resisting joint Dismantling plate We supply profiled rubber-rings with blue stripes. Fixing of this marking rings should be in accordance with the illustration. 6235
