Description

PIB Welding Agent is a fast evaporating solvent used as a welding solvent based on non-aromatic solvents. Used for welding and bonding Plysolene PIB together using application advice below as a guide.

Technical:

  • Application - Welding Solvent
  • Density - 0.72
  • UN Number - 1268
  • Odour - Low - aliphatic
  • Colour - Clear
  • Flashpoint Degrees C - 25
  • Water Miscible -  No
  • VOC Content %age Volume – 100

Application:

PIB sheeting is very easily applied to the insulated pipeline. Suitably sized pieces are cut and wrapped around the outside of the insulation. Endlaps of 80mm should be allowed and 500mm side laps underneath the pipes.

The overlaps are solvent welded by applying Plysolene Welding Agent E with a stiff brush.

The solvent should be applied with a circular scrubbing movement to both surfaces so that they become tacky before the overlap is pressed together. The use of too much solvent can cause premature failure as the excess solvent will continue to dissolve the PIB long after the weld has been made.

PIB is a thermoplastic elastomer and does soften with increases in temperature and therefore it should not be used to hold the insulation in place around the pipe. This should be secured in place prior to covering with PIB.

For very large ductwork/pipelines, having a diameter in excess of 300mm, use 1.0mm or 1.2mm.

For ventilation ductwork, the sheeting should be fully bonded to the fixed insulation material, which should be high density resin bonded glass-fibre or mineral-wool slab. If expanded polystyrene is used, the edges of the polystyrene should be well taped and all sections should butt up to one another to minimise the effects of movement and to prevent a temperature gradient existing over any gap.

The main cause of failure on ventilation ductwork is air leakage within the ventilation system.

Any air leak leads to a build-up of moist air within the insulation material that becomes wet as the air cools and condensation occurs. Over a period of time this can lead to a complete failure of the lagging. The best solution is to eliminate all air leaks, but if this is not possible, very small ventilation holes in the underside of the ductwork can prevent the build-up of moist air within the insulation.
