Bolt Torque & Tensioning

ISS offers hydraulic bolt torque/tensioning services to serve most industrial requirements. The controlled application of torque on a flange joint connection ensures even distribution and uniform displacement of pressure. Specific applications are determined based upon the critical nature of the flange and the pressure, temperature and material that will be passing through the line. Also calculated into the process is the “k” factor or friction coefficient that comes into play when bolting lubricants or Teflon is introduced. Bolt elongation can be verified utilizing extensometers and trained technicians.
