STEEL EXPANSION JOINT TYPE SG-11 NOTE 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 – 50 FEMALE THREAD STRUCTURE TYPE Sg-11 / STEEL BELLOWS PN 16 acuum-proof axial expansion joint consisting of a stainless steel V bellows and threaded connection parts Bellows with flared ends, connection parts with union nut and flat packing onnection parts with female thread C Multiple convolution bellows in various stainless steel grades Single 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. APPLICATIONS for compensating axial movement for reducing tension, in pipes and their system components, e.g. pumps compressors engines turbines machines to compensate for installation inaccuracies for installation in exhaust systems heating installations gas supply lines VERSIONS / Threaded connection parts Female thread Union nut with female thread acc. ISO 228-1 Standard Dimensions Corrosion protection PRESSURE RATE STANDARD PROGRAM PN 16 DN C ax Axial spring rate N/mm A* Effective bellows cross sectional area cm2 Ø D2 Female thread Ø inch 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. **This value represents the total possible movement. Example: D axtot= 28mm. This means that the expansion joint has a total movement value of 2
