CPI-CATJOINT

CPI-CATJOINT for fuperior cathodic protection , it is a monolithic isolating joint which effectively and efficiently stops short circuits and stray currents from damaging pipelines and equipment.  Employs one or more, preassembled pressure seals and isolating ring.  Unlike isolating gasket kits, CPI-CATJOINT does not depend on an installer fitting gasket, sleeves and washers into a flange on location. Any one of these parts could be damaged causing a complete breakdown of the isolated flange, thus loosing cathodic isolation.  Because are welded into place as one piece units, field problems are virtually non-existent and the integrity of the isolation is kept intact. Furthermore, once installed, CPI-CATJOINT can be buried and forgotten ending your maintenance worries. In contrast, inspection pits and vaults must be used to monitor below ground isolation gaskets. And constant visual inspections of above ground isolation gaskets are necessary to check for shorts in the gaskets. This requires a continuing maintenance program during the entire life.

No  loss  of  integrity  due  to  thermal  expansion  or  ground  stress  as  is  common  with  flange  insulation  gasket  kits.  100%  tested  hydrostatically  and  electrically,  to  1-1/2  times  working  pressure.  Non-destructive  testing  is  also  available.

Maintenance-free,  reliable  cathodic  isolation  of  equipment  in  required  isolation  applications  such  as  compressor  stations.

  • 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.

In extreme applications they are […]

  • O-RINGS

    O-RINGS The use of O-rings extends to many fields. The main function that characterizes this type of joint is its ability to maintain the seal, preventing the mixture of liquids and gases. They are characterized by their versatility and resistance to high pressures and temperatures. The type of elastomer used in its manufacture can vary. We can offer […]

  • RTJ GASKETS – TG30-TG31

    RTJ joints are indicated in applications high pressures and temperatures. They are designed to be accommodated in specific slots and flanges contact surfaces of the gasket and the flange must be carefully machined and finished. They are particularly suitable for very high pressures, up to 1000 psi. The RTJ gasket material should be a little softer than the flange itself […]
