Floating Head Failure

This pix shows the typical failure at the leading edge of floating head.

ERS Rehabilitation includes

  • Blasting to removed all failed coating and corrosion.
  • Salt-X to draw out chlorides and other contaminants.
  • Welding and machining at Schmidt to re-establish the proper mating surfaces.
  • Blast again to remove salt bloom, other contaminants and properly prepare the surface for coating applicationApply 2 coats of ERS-5400 Channel Guard 5400 HP @ 8-10 mil/coat within overcoating window.
  • Apply 1 coat of ERS-5600 Rino Glass @5-6 mil and trail this final coat up over the leading edges and onto both the partition plate and circumferential gasket surfaces, over the nubbin (if any) and terminate at the bolt circle.
  • We take care to break the sharp corner of the leading edges to create a single monolithic coating system incorporating the gasket surfaces and wetted surface areas.  This system eliminates the failure point at the leading edges.
