No loss of integrity due to thermal expansion or ground stress as is common with flange isolation gasket kits
In-factory tested hydrostatically and electrically, to 1 1/2 times their working pressure. Non-destructive testing is also available.
Maintenance-free, reliable cathodic isolation of equipment in required isolation applications such as compressor stations The notion that flange isolating gasket kits are more cost efficient than monolithic joints is not well supported when figuring in all the variables. Materials, labor intensive installation, pre-online inspection and continuous maintenance as well as possible and probable replacement of deteriorated gasket kits all add up, ultimately making the IsoJoint® a very effective and cost efficient method of cathodic isolation. Benefits & Advantages Advantage In Savings
No labor intensive, complicated installation procedure required as with isolation gasket kits
No inspection pits, vaults or maintenance needed - weld into place and direct bury - reliable, worry-free cathodic isolation
Non-conductive epoxy coatings help prevent shorts, both externally and internally
Isolates stray currents impressed on the pipe from exterior forces such as electrical transmission systems, earth currents and currents flowing from point to point
Excellent bending and torsional resistance
Earthquake resistant - Acts as a thrust block or joint
