Socket inside in particular sealing ring seat and retaining groove
Sealing ring
Apply lubricant to the hatched sealing face only.
Inserting the sealing ring
Clean the sealing ring and fold it so to form a heart.
Insert it into the socket such that the outer hard rubber claw sits firmly in the retaining groove.
If necessary, make two loops and smoothen them out.
The inner edge of the hard rubber sealing ring must not protrude from the centring collar.
Applying lubricant
Apply a thin film of lubricant to the inserted seal and to the spigot end – in particular to the chamfer.
Assembling the joint Push the spigot end concentrically and straight into the socket until it touches the sealing ring. The axes of the two joined elements (pipe sections or fittings) must form a straight line. When you are ready, check the sealing ring for firm seat all-round with a feeler gauge. Use the fitting tool to push the spigot end further into the socket until the second marking line is visible only. Tab 1, page 53 Last rev.: 05/2014

This thrust-resisting socket joint renders concrete anchoring blocks superfluous. The number of socket joints to be secured this way shall be determined as specified in DVGW standard GW 368. Always contact our customer service before you use these joints in gas pipelines, suspended pipelines or bridge pipelines.
1. Clean the socket and spigot end. 2. Clean the Tyton SIT® / TYTON SIT PLUS® ring, fold it so to form a heart and insert it into the socket. Note that the inner bend shall be situated between two steel segments (see Fig.). Apply a thin film of lubricant to the inserted sealing ring. 3. Slide the profiled code ring with colour stripe (blue for Tyton SIT® and white for TYTON SIT PLUS®) onto the spigot end. 4. Apply a thin film of lubricant to the spigot end – in particular to the chamfer – and insert it into the socket until it touches the sealing ring. 5. Attach the fitting tool to the socket and spigot end and force the spigot end into the socket. Make sure the spigot is inserted concentrically and straight. Caution! Turning an element in the circumferential direction (e.g. to bring a branch connection into position) shall be avoided; if unavoidable, it is essential that this is done before locking.

We supply a profiled rubber code ring with colour stripe on the outer shell (blue for Tyton SIT® or white for Tyton SIT PLUS®) for permanent marking. The code ring shall be attached as shown in the drawing.
Dismantling the thrust-resisting joint Unlocking tool
Note: After assembly of the thrust-resisting joint, the joined elements may be offset by an angle of up to 3°.
• Attach the fitting tool and force the spigot end further in towards the base of the socket, thereby relieving the steel segments. • Apply lubricant thinly to either side of the unlocking tools and hammer them into the gap at the socket all-round as far as they will go. • Take the joined elements apart with the help of a dismantling clamp or fitting tool. • If the unlocking tools cannot be driven in on the entire circumference, then the pipeline must be cut apart.

Fitting instructions for self-anchored joints Keula thrust protection for screw-gland socket joints
Application Keula self-anchored joints can be used in pipelines with sizes from DN 80 to DN 400. They are reliable up to a test pressure of 25 bar (DN 80 to DN 300) or 16 bar (DN 350, DN 400). The form-fit connection caused by the wedge-shaped grooves serves to absorb the thrust force caused by the internal pressure and makes an otherwise required concrete anchoring block superfluous. The wedges are nitrided to provide corrosion protection.
Preparation Pipe or F piece spigot end: Socket inside: Threaded ring: Sealing ring and sliding ring: Wedges:
Clean a length of about 200 mm and remove any paint residues. Remove any soiling. Make sure that the pockets in the threaded ring are unclogged. Apply a thin film of DVGW-approved lubricant to the sealing ring and sliding ring. Identical wedges are used for all nominal sizes. DN

Fitting instructions for self-anchored joints Keula thrust protection for screw-gland socket joints
Assembly and dismantling – Mount threaded ring (1), sliding ring (2) and sealing ring (3) (in this order) to the spigot end of pipe section or fitting (5) such that the distance (4) to the chamfer is at least 5 mm. – Fix the marking (7) in this position. – Screw parts 1, 2, 3, 5 and 6 (without wedges) together finger-tight and attach them firmly to the connection points so to adjust the required distance and offset angle (max. 2° to either side). – Tighten the threaded ring firmly with a suitable tool and check that the distance to the mark does not exceed 5 mm. – Insert the wedges (8) into the pockets of the threaded ring with their tips first and with their teeth facing the pipe. – Drive the wedges in all-round against the screwing direction with strong hammer blows (1.5 kg) so that about identical drive-in forces are exerted on opposite wedges. – How far they will actually go in depends on the offset angle and nominal size of the fitting (see drawing). – Use a hardened punch (size 10 x 15 x 150) if necessary (obligatory for nominal sizes of DN 250 and more). – While the wedges are driven in the triple teeth cut into the outer diameter of the pipe, thereby creating the thrust protection. – Cut off protruding wedge ends at right angles with an angle grinder. – If you turn back the threaded ring the wedges will be released and can be used again. – After about 3–4 turns, the joint is released such that the joined elements can be pulled apart and the wedges can be taken out. After having released the joint, you may grip the wedges with multigrip pliers to pull them out.

Slide the bolted-gland ring and the sealing ring beyond the mark. Insert the spigot end into the socket concentrically and check the insertion depth. Push the sealing ring uniformly into its seat. Do not use lubricants.
Tab 1, page 64 Last rev.: 05/2014
Fitting instructions for STO joints Bolted-gland socket joint
Assembling the joint Push the bolted-gland ring towards the sealing ring and align it with two hardwood wedges which are inserted between gland ring and spigot end on the top side. If the bolted-gland ring is well centred then it will be easy to insert the T-head bolts later.
Hardwood wedges
Insert the T-head bolts into the bolted-gland flange and bolted-gland ring and treat the T-head bolts and nuts with commercially available bitumen varnish. Screw on the nuts finger-tight. Now tighten the nuts with a ring spanner crosswise by a half to one turn each time.
The bolts are sufficiently tightened when the gland ring has been forced at least 6 mm into the sealing ring. The insertion depth after tightening the bolts can be determined by measuring the bolted-gland ring height and the distance from the outer edge of the bolted-gland ring to the sealing ring. The insertion depth should be as uniform as possible for a particular bolted-gland socket joint. Each joint thus requires at least three measurements at different points. Double-check the correct insertion depth. After having assembled the joint, pipe sections can be offset by an angle of up to 3°.

Fitting instructions for FF joints Flange-to-flange joint General
Tightening torque of the bolts of flanged joints with rubber gaskets The torque depends on the sealing material, the nominal size DN and the nominal line pressure PN. It can be calculated with the help of the following equations: MDPN 10 = DN/30 da Nm MDPN 25 = DN/10 da Nm MDPN 16 = DN/15 da Nm MDPN 40 = DN/ 5 da Nm (1 da Nm ≈ 1 kpm)
Position of the bolt holes in flanged fittings Generally, bolt holes in flanges shall be positioned such that they do not lie in a plane perpendicular to the plane of the pipeline. Due to the different number of bolt holes at the two ends of FFR pieces, upstream and downstream elements may lie twisted when such a piece is mounted wrongly.
