Bolt Tightening Software Specification
Important Information
The data produced by this software is only applicable when using Powermaster Bolt Tensioning tools.
The recommended bolt stress values assume that flange material yield strength is equal to or greater than 247 N/mm2.
Do not use the recommended ANSI B16.5 bolt stress values for flanges manufactured with material yield strength less than 247 N/mm2.
Flange service temperature range for the recommended bolt stress values are -101 ͦC to +200 ͦC. Or as limited by the piping class specifications or the bolt minimum or maximum temperature specification. Do not use the recommended bolt stress values outside of this range of temperature.
