Stenflex Type: 12F DN80 Swivel Joint

■ A pressure resistance test according to Annex 1, Section 3.22 of the Pressure Equipment Directive 2014/68/EU is normally not carried out by the manufacturer. This is to be
performed by the user after installation in the piping system (PT = 1.43 x PS).
■ The user is responsible for providing any necessary safety and monitoring facilities (such
as the installation of temperature sensors, pressure-limiting valves, measures for avoiding pressure jolts and liquid hammers).

manufacturer. Tighten the screws several times in a crosswise manner so that an evenly distributed seal-pressing
effect is achieved. After approx. 24 hours of operation, the settling is to be balanced out by
re-tightening the screws. In the unlikely event of a leak the manufacturer must be contacted.
For torques which are not stated please contact the manufacturer.

■ Non-tensioned rubber-type expansion joints can be applied for the combination (superimposition) of axial, lateral and angular movements. Observe the reduction of the
individual movements! If in doubt, consult the manufacturer.
■ Fixed points must definitely be adequately dimensioned. Fixed points must be capable
of coping with the force FFP from the sum of the axial thrust force (F1), the expansion joint
adjusting force (F2) and the frictional forces from the guide bearings (F3) (Fig. ).
■ In principle, o n l y one expansion joint shall be installed between two fixed points.
■ With several axial expansion joints, the pipe pattern must be subdivided by interim fixed
points.
■ The piping with axial expansion joints must be exactly guided with bearings. Guide bearings are to be arranged on both sides of the expansion joint. A fixed point replaces a
guide bearing. Fig. .
