Internal Coating Pipes

Maharashtra Seamless Limited (MSL) manufacture and supply internal coated pipes (epoxy coated). A spraying nozzle has been used to spray the liquid epoxy inside the pipe as per the required thickness. Before applying the epoxy paint, internal surface of the pipe is cleaned. The typical coating thickness for gas pipelines varies between 60 to 100 μm and for water and other liquids it varies between 200 to 500 μm.


  • Increase flow of gas/water by 20%
  • Suitable for Service Temperature up to 80°C
  • Excellent Corrosion Resistance
  • High Steel Adhesion
  • Low mechanical & abrasion Resistance
  • High Impermeability for water / gas
  • Low Electrical Resistance
  • Ease of cleaning the pipeline and ease of water
  • Decrease line maintenance and up keep costs
