FRB Coating Tank

The coating system consists of applying a coat of coal-tar enamel having a minimum thickness of 24 micron/2.4mm over the primed pipe and one wrap of glass-fiber mat.

A second coat of coal-tar enamel having a minimum thickness of 2400 micron/2.4mm follows this and wrap of glass-fiber mat followed immediately by an outer-wrap of coal-tar impregnated glass fiber felt.

The minimum thickness of coating (without the outer-wrap) is 4800 micron/4.8mm +/- 1.0/0.0mm. When the protrusion of weld seam interferes with this thickness, the thickness of the coating above the weld seam should meet the specified thickness.

For water, crude oil and gas pipelines, the anti-corrosive protections mostly utilized are hydrocarbon base systems (oil or pit carbon derivates) mixed with mineral fillers.

Features & Benefits

  • Do not crack
  • High tensile strength / breaking, tear strength Resistant to longitudinal / transverse tension, provides reinforcement, protection from mechanical damage due to strain on pipe during handling - laying, commissioning & operation, withstand pressure due to soil movement, cold bending etc.
  • High temperature resistance / tolerance - thermally stable, stable up to 288 0C, can be used in both hot & cold application, unaffected under load in hot bitumen at 288 0C, structural, composition stability
  • Smooth surface

Additional strength added by yarn reinforcement spacing option.
