Pipe support variant 2
Maximum allowable torques
Standard bolts must be well lubricated and tightened evenly around gasket.
Leakage/damage to water meter or piping may arise if bolts are overtightened.
Torque calculations
All values are theoretical and are calculated on the assumption that:
● All bolts are new and material selection is according to EN 1515-1 table 2.
● Gasket material not exceeding 75 shore A is used between the water meter and mating
flanges.
● All bolts are galvanized and adequately lubricated.
● Flanges are made of carbon steel.
● Water meter and mating flanges are correctly aligned.
