NEE has the capacity to electropolish and passivate your large vessel fabrications up to 8’ long by 5’ in diameter. Our expertise includes:

  • Thorough understanding electropolishing large vessels – From rigorous surface finishes to aesthetic requirements, NEE can meet your requirements.
  • Expert surface prep – NEE specializes in the tooling, masking, and surface preparation often needed due to the wetted surfaces, ports and flanges of large vessels.
  • Design and in house fabrication of custom cathodes – To ensure we meet your specifications, NEE designs and fabricates custom cathodes, a critical component of the large vessel electropolishing process.

Companies in the pharmaceutical, vacuum, marine, architectural and food service industries turn to NEE for their large vessel electropolishing needs. Our process fully complies with ASTM B912, “Standard Specification for Passivation of Stainless Steel Using Electropolishing.”

Examples illustrating how we can help you:

large electropolished part

NEE specializes in stainless steel finishing of very large parts, such as this 10’+ manifold, part of a water purification system.

large component finishing

NEE’s capabilities include electropolishing large bulky items, such as the finishing of this stainless steel housing. Electropolishing helps reduce corrosion and gives parts a clean, uniform finish.
