Monolithic Isojoint

IsoJoint® provides for current control by separating pipe work into distinct zones and effectively eliminating long-line currents. This assures increased plant and equipment life by reducing or eliminating corrosion damage. 

  • No inspection pits, vaults or maintenance needed - weld into place and direct bury - reliable, worry-free cathodic isolation

  • Isolates stray currents impressed on the pipe from exterior forces such as electrical transmission systems, earth currents and currents flowing from point to point

  • Butt Welds at either end of the Joint to Weld into place and direct bury

  • 1 year Warranty

  • Stock Available: 2” thru 20” ANSI 150, 300, & 600

  • Non-conductive epoxy coatings help prevent shorts, both externally and internally

  • Hydrostatically tested (1.5xMAOP)

  • Designed & Manufactured to ASME VIII, Division I

  • Isolates stray currents impressed on pipe from exterior forces such as electrical transmission systems, earth currents and currents flowing from point to point

  • Ultrasonic, X-ray and dye penetrant tested

  • Non-conductive epoxy coatings help prevent shorts, both externally and internally
