Thread Line Piping

  • Pipe is gravity fed into measuring system, then roll cut to length and label is applied
  • Pipe is then gravity fed to Landis threading machines
  • Thread sealant with Teflon is applied
  • Thread fittings are assembled to the pipe
  • Assembled Pipe is gravity fed to the PACE make on machine then hydraulically Torque
  • Line piping is separated by the number inclusive of all diameters then tied in easy to handle groups
  • Master bundles are color coded
  • 2'-6' and under bagged pieces contents are marked, palletized, shrink wrapped, identified and color coded

Welding Piping

  • Pipe is gravity fed into the N.A.P Quick cut measuring system and cut to length
  • Pipe is labeled and color coded
  • Gravity fed to PACE hydraulic roll groove machine
  • Groove depth and flare are checked
  • Additional procedures for galvanized pipe
  • Pipe is then gravity fed to the N.A.P. Universal Welder
  • Outlets welded to galvanized pipe are galvanized cold sprayed
  • Blast cannon removes all dust and dirt from inside of pipe
  • Welds are die penetrate and developer tested
  • Pipe is bundled by identification wrapped and color coded

Hanger

  • Plain or Plated rod can be cut to length and assembled with fastener and ring
  • Hanger assemblies are grouped, tied and tagged by the identification number
  • Hangers are bagged, palletized, wrapper identified and color coded
Hydralist fabrication sheets are provided with the delivered project
