Laying instructions for ductile cast iron pressure pipes and fittings, equipped with thrust-resisting joint Düker SPEZIAL, particulary for flanged sockets and collars 2486 Assembling steps: • Clean spigot/s in the area of sealing moves and mark the installation depth. • Insert screw ring, locking ring/s (DN 80 – 250) or element rubber ring/s (DN 300 + 400), SPEZIAL screw-ring/s, gliding ring/s (DN 80 – 400, t = 3 mm) and gasket/s (lubricate inside) in this sequence onto the spigot and pay attention to the correct position (see mounting drawing). • Lubricate spigot/s, thrust-face/s and outside surface/s of gasket/s, gliding ring/s and locking ring/s (element rubber ring/s), the thrust-face/s and thread of screw rings as well as sealing chambers and the thread of the sockets with lubricant. • Insert spigot into the socket and check the installation depth. In case of installing a collar lubricate sealing chambers and thread of screw, too and insert them onto a spigot. After the axial positioning of spigots to each other (avoid deflection and observe installation depth), put the collar in centre to the spigots and adjust centrical. • Impress gasket equable into the sealing chambers. Push gliding ring until it touches the gasket. Screw down screw ring by hand as far as possible and tighten it with the help of a hammer or ram. Here, avoid the turning of the socket. In case of installation a collar tighten both sides alternately. The turning of the socket can be avoided by using a second hook wrench (see illustration). Because of the setting behaviour of the gasket, a post hammering after 5-10 Minutes is recommended. • Turn in the locking rings (element rubber rings) until it touches the SPEZIAL screw ring. Insert the screw rings by hand and tighten them with hammer blows. • Deflection: After finishing the connection in centrical position, pipes can be deflected up to 3°. For mounting the connection, the following parts are necessary: Pos. 1: Screw ring made of ductile cast iron, inside chamfered Pos. 2: Element rubber-ring with segments made of steel Pos. 3: gasket Pos. 4: Special screw ring made of ductile cast iron, with internal- and external screw thread Pos. 5: Simple gliding ring made of steel Mounting drawing for collars with thrust-resisting joint Düker SPEZIAL 6249
6 Laying 250 instructions for ductile cast iron pressure pipes, fittings and valves, equipped with thrust-resisting joint Novo GRIP ® III Application field: Novo GRIP ® III-locking rings are available for dimensions DN 90 / 110 / 140 / 160 / 225 and for nominal pressures 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 have to be observed. Before installation in lines for bridges, ducts or river-crossings, please contact our service team. Gasket Novo GRIP ® III-ring PE-HD-pipe Assembling steps 1. Cleaning of socket and spigot. 2. Insert gasket into TYTON ® -chamber. 3. Insert Novo GRIP ® III-ring into pre-chamber. 4. Spigot of pipe has to be rounded and smoothened. 5. Insert stabilising bush completely. 6. Throb spreading wedge into stabilising bush until stretching. Backlog of spreading wedge has to be cut to justify with the bush. 7. Insert pipe into the socket through Novo GRIP ® III-ring until touching the gasket. 8. Connect the joint by employing commercial pipe-laying tools. Please avoid deviation during drawing the spigot into the socket! Important: Changes of circumferential directions have to be arranged before connecting. (f.e. installation of outlets, tees a.s.o.) Note: Fittings and valves with a nominal dimension of DN 200 for pipeline diameters of 225 mm haven‘t got a standard Novo socket! These parts are equipped with an adapted geometry and are marked with the sign „for PE-HD Pipes“. Please consider this when you order your pipeline components. 6251
