Features/Benefits:

  • Compact design
  • Low profile
  • Complete range of sizes and pressure classes

  • Weld preps are per API 5L (ANSI B16.25 available upon request)
  • All welding processes are in accordance with ASME VIII and IX
  • Manufactured to applicable ANSI, ASTM, ASME, AISI, API, IEC, and ISO standards
  • Each joint is factory tested to verify the mechanical integrity and electrical resistance to satisfy cathodic protection requirements
  • Manufactured to ISO 9001 quality standards
  • Epoxy coated
  • Eliminates electrical shorts and stops stray current in a pipeline system
  • Most economical and reliable method that can be used to cathodically protect a pipeline system
  • Can be installed above or below ground
