GOAD'S New Tank Lining Technology Featured in Article by NACE® International
Submitted by: GOAD COMPANY
St. Louis, MO (OPENPRESS) November 4, 2011 -- GOAD COMPANY announced today that international corrosion engineering society, NACE® International, has published an article that features GOAD'S development of a new welding technique used with flexible PVC linings.
The story, published in the October edition of Materials Performance, reports on an improved welding process for polyvinyl chloride linings (PVC) developed by GOAD that, "helps prevent aggressive chemicals from seeping behind a plastic lining and attacking the underlying substrate."
The article contrasts the decades old hot gas/hot air welding technique with the new patent-pending welding method and carried out by a machine. The old traditional welding method, carried out by hand, relies on seams and strips to seal the joints between sheets. This approach leaves perfect channels and gaps at these intersections behind the tank lining. If the hot air sealing isn't executed perfectly or a leak occurs and contained solution reaches these gaps, the solution is now free to flow behind the entire lining system and corrode the substrate.
GOAD COMPANY CEO Curtis Goad, who was interviewed for the story, revealed that the new N-FUZE® welding technology is based on the much higher quality and more consistent extrusion welding process used on rigid plastics. The article goes on to point out that the major benefit of machine welding is that it produces an extrudant that, "infuses into the substrate's pores and voids as well as joins the PVC sheet lining." Tank linings carried out in this manner outperform hand welded linings and have a service life 2 to 3 times longer.
GOAD COMPANY has manufactured process vessels for well over 50 years and services industrial linings in tanks and pits all over North America from its central U.S. location in Missouri.
