Swastik Pipe Wrapping Tape is a hot applied bituminous tape for corrosion protection as per IS: 10221, it is specially formulated corrosion resistant bitumen compound provides high penetration and high resistance to ageing. Swastik Pipe Wrapping Tape comprises of high tensile strength thermo-fusible HMHDPE film on both the sides. 2 mm Pipe Wrapping Tape is five layer without fiber glass inner core, whereas, 3 / 4 mm thick Pipe Wrapping Tape is seven layer tape with two inner cores; top core is of tough 45 gsm fiber glass and the bottom core is of 15 micron high tensile strength HMHDPE.

 

APPLICATION :

  • Coating material for drinking water pipelines, fire fighting pipelines, raw water pipelines in thermal plants etc.
  • Applied on buried and immersed pipes, fittings and appurtenances to protect them from high corrosive environment

 

ADVANTAGES :

  • Coating material for drinking water pipelines, fire fighting pipelines, raw water pipelines in thermal plants etc.
  • Applied on buried and immersed pipes, fittings and appurtenances to protect them from high corrosive environment Application

 

APPLICATION METHODLOGY :

  • Remove dust, flakes, oil, grease or other loose foreign particles by blasting, wire brush or compressed air.
  • Leave 200 mm from pipe ends for welding joints. Coat and wrap such left over part of pipe at site after welding and hydro testing.
  • Apply Primer on cleaned surface at 0.30 L/m2 to get DFT of 30 microns. • Allow the primed surface to touch dry, which may take 5 - 15 minutes.
  • show the flame of butane gas torch on to the surfaces till it becomes glossy-smooth.
  • Apply SWASTIK PIPE WRAPPING TAPE on the primed surface. Provide overlap of 25 mm between two adjoining layers. 
  • Wrap spirally and apply sufficient tension to ensure good adhesion and avoid pockets and bridging to meet holiday detection requirement. Tape joint shall face downward on outside of lap joint.
  • Complete necessary welding and testing of the joint before coating.
  • Recommend to apply at the time of pipe erection and lowering inside trenches to avoid any damage.

 

HEALTH AND SAFETY :

  • Use goggles and hand gloves during application 
  • Clean hands with warm water after application.

 

STORAGE :

  • Keep under shed away from heat. Do not stack more than three rolls in one column.
