CAUTION | |
Bolts secured with Nord_Lock washers must be tightened to 15% more torque than the values shown in this table. If Loctite 243 is applied, the below tightening torques have to be increased by 50 %. Apply the values to bolting connections between EKATO components. For bolting connections of subsuppliers’ components refer to the values given in the subsuppliers’ manual (→ chapter 9) For bolted connections (eg screw with nut) inside the vessel, which are made of different materials, the material with the lower torque value at operating temperature (see table) is relevant to the selection of the proper tightening torque. Do not apply the values to clamping hubs made from bent plates, not to EKATO set screws, not to standard set screws and not for mounting flanges; see separate data (→ chapter 4.3) For special materials not mentioned here check the data on the following page or on the assembly drawing, (→ chapter 1), or the agitator cross sectional drawing (→ chapter 8) The values apply to optimum lubricated threads, i.e. both the thread and the nut seat shall be lubricated with thread grease based on molybdenum disulphide (MoS2) or chlorinated paraffin; remove excess-lubricant from the parts in contact with product; if necessary use special grease with food compatibility For threaded joints outside the vessel normally the ambient temperature applies; exception: boltings between seal or lantern and mounting flange, in these cases the process temperature applies |
