Inflatable Purge System 150mm Inflatable Purge Dam TMIPS006

Especially insulated heat covered infl atable purge system for purging applications in pre-heated pipes can be supplied upon requested

  • Made from fi re-retardant “Flameshield” proban cotton for increased resistance to
  •  damage from scorching and burning.
  •  Armoured, robust connection hose.
  •  Bypass hose for additional gas inlet/exhaust.
  •  Reinforced stitching and crimping for improved tear-resistance.
  •  Strong eyelet pull loops.
  •  Reduces fl ow rate during hot passes to 5 to 10 lpm.
  •  Available for pipe diameters from 2” to 96”.
  •  Special hose barb connections available for easy connection to gas source

OPERATION OF INFLATABLE PURGE SYSTEM
Step 1

  • The defl ated Purge System can be easily placed in the pipe by using the pull tags.

Step 2

  • Once the two dams of the Purge System are in position on either side of the weld joint, there is a glowtape in the middle of the dams to advise “in position”.
  • The dams are infl ated by opening the argon source to 5-10 lpm fl ow rate and will quickly seal the pipe.
  • The pressure will open the purge valve and purging of the space between the pipe and the purge dam begins once dams are infl ated.
  • During purging, the air between the Purge System and the pipe is pushed through the exhausts of the purge system away from the vicinity of the weld until the oxygen level is low enough to start welding, as per the welding procedure.
  • Use a purge gas monitor to advise oxygen levels.
  • The Purge System requires a constant fl ow rate of inert shielding gas of up to 3-5l/min to maintain a positive purge pressure.

Step 3

  • After completion and the weld has cooled below oxidation temperature the Purge System can be easily defl ated by interrupting the argon gas supply. Once defl ated remove from the pipe.
  • Note: For best welding results, use infl atable weld purge together with a weld gas analyser
  • (TMWGA001 or TMSCGA) and aluminium tape to seal the prep areas while purging to reduce gas usage.

Applications

  • The Purge System can be used whenever welding stainless steel and reactive metal pipework.
  • Also suitable for purging autogenous weld fi t ups as well as scheduled pipework that requires a gap between two bevelled pipe ends.
  • Standard Purge Bags: 100°C
  • Heat Resistant Purge Bags: 350°C continuous - 500°C short term
