STEEL EXPANSION JOINT TYPE SF-11 Please comply with the general technical instructions regarding reaction force, moving force, fixed point load, installation instructions, etc. Subject to technical alterations and deviations resulting from the manufacturing process. AXIAL EXPANSION JOINT DN 15 – DN 500 STRUCTURE TYPE SF-11, STEEL BELLOWS PN 16 Vacuum-proof axial expansion joint consisting of a stainless steel bellows and welded flanges Multiple convolution bellows in various stainless steel grades Single ply or multi-ply structure Material grade* Possible uses Stainless steel Low temperature, acids, lyes, gases, fertilizers Media containing chloride, oil, soap, drinking water, food stuff, petrol * Check or inquire about the resistance of material grades to temperature and medium. ** Check or inquire about reduction in pressure by temperature. FLANGES / VERSIONS APPLICATIONS for compensating axial movement for reducing tension, in pipes and their system components, e.g. pumps compressors engines turbines machines process plants for installation in industrial applications gas and water supply exhaust systems heating installations to compensate for installation inaccuracies GUIDE SLEEVE Materials Standard: 1.4541 Welded flanges with turned seal Flange drilling for through bolts Standard Others ANSI, BS etc. Connection dimensions see technical annex page 213 – 215 Corrosion protection anti-corrosion primed SPECIAL DESIGN Other sizes (DN), lengths or pressure ratings on request.

PRESSURE RATE STANDARD PROGRAM PN 16 DN Ø di Internal guide sleeve Ø mm For larger sizes (DN) please see type SF-16. Also available with PN 10 flange connection. Table values refer to +20 °C, bellows material 1.4541, 1000 cycles. Max. allowable pressure pulsation of 1.6 bar (brief periods). Please inquire for deviating values. *Effective bellows cross sectional area is a theoretical value. ** his value represents the total possible movement. Example: D axtot= 28mm. This means that the expansion joint has a total movement T value of 28 mm (= +/- 14 mm). DN 15 – DN 32 Type SF-11 without inner...
