STEEL-EXPANSION JOINT TYPE SF-10 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 2800 STRUCTURE TYPE SF-10 Steel bellows PN 2,5, PN 6, PN 10, PN 16 Vacuum-proof, short-length axial expansion joint, consisting of a stainless steel bellows and rotable flanges Multiple convolution bellows in various stainless steel grades Single ply or multi-ply structure DN 15 – DN 500 with flared ends DN 600 – DN 2800 with pre-welded flared ends Material grade* Possible uses Stainless steel Low temperature, acids, lyes, gases, fertilizers Heat-resistant steel Nickel-based alloy Media containing chloride, oil, soap, drinking water, food stuff, petrol Hot gases, steam, air Sulphuric acid, phosphoric acid, petrol, öl, gases * Check or inquire about the resistance of material grades to temperature and medium. ** Check or inquire about reduction in pressure by temperature. FLANGES / VERSIONS Rotable flanges Flange drilling for through bolts Standard APPLICATIONS for compensating axial movement for reducing tension, damping noise and oscillation in pipes and their system components, e.g. pumps engines machines for installation in industrial applications gas and water supply exhaust systems heating installations drinking water systems to compensate for installation inaccuracies SPECIAL DESIGNS Other sizes (DN), lengths or pressure ratings on request.

PRESSURE RATE STANDARD PROGRAM PN 2,5 C ax Axial spring rate N/mm Table values refer to +20 °C, bellows material 1.4541, 1000 cycles. Please inquire for deviating values. For pure axial movement: inner diameter of internal guide sleeve mentioned in tables PN 6, PN 10, PN 16. If D ax and D lat occur simultaneously, the table values must be reduced accordingly. The sum of all shares must not exceed 100 %. *Effective bellows cross sectional area is a theoretical value. ** his value represents the total possible movement. Example: D a

STEEL EXPANSION JOINT TYPE SF-10 AXIAL EXPANSION JOINT DN 15 – DN 2800 PRESSURE RATE STANDARD PROGRAM PN 6 C ax Axial spring rate N/mm A* Effective bellows cross sectional area cm2 Table values refer to +20 °C, bellows material 1.4541, 1000 cycles. 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 value T of 28 mm (= +/- 14 m
