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. Effective control can be attained where a branch is connected to the mainline, where two pipelines of different material connect or where well-coated pipe meets a poorly coated system. Advance Products and Systems, Inc., is the exclusive provider of the IsoJoint® monolithic weld end isolating joints. The IsoJoint® is manufactured in sizes ranging from 1/2” diameter to 150” diameter with an ANSI rating of 150# to 2500# and up to API 10,000#. All types of carbon and stainless steel are used in their manufacturing. For truly superior cathodic isolation, Advance Products and Systems offers an IsoJoint® manufactured according to ASME VIII Division 1 standards and certified by ISO 9002 Quality Assurance making it the supreme monolithic joint on the market today.
