Shuk Product Catalogue


Flange insulating sets are used in flange applications where electrical isolation and resistance to corrosion are required. The kits are used as an insulator between dissimilar metal flanges or to electrically isolate sections of pipework in cathodic protection systems, preventing the flow of electrostatic charge along the pipelines. They are designed to minimize the effects of Electro- chemical corrosion. Our Flange Insulation Kits provide the perfect seal, and protect flanges, valves and pipelines against corrosion while improving safety and reducing the risk of fire. Our kits have a wide range of applications

but are typically used on offshore rigs, chemical installations and oil refinery pipelines, where galvanic corrosion protection and electrical insulation are required. The temperature range for the gasket is -54ºC to 104ºC and they are constructed from materials with extremely robust dielectric strength. Flange Insulating Kits come in three sets - RF, FF and RTJ. Each set is supplied with a gasket, sleeves and washers, plus steel washers.

The gasket can be:

• Raised face (type F - IBC)

The gasket for RF and FF is either 3mm thick phenolic or 3mm thick Neoprene faced phenolic.

• Full face (Type E)

• Oval RTJ gasket (Type D)

The gasket for RTJ type is an oval phenolic RTJ gasket.

Pikotec ‘VCS’ Insulating sets also available, suitable for either RF/FF or RTJ Flanges. Gaskets with steel core, spring energized seal ring SS316/ (PTFE), G10 washers, Mylar sleeves and steel washers (other materials upon request).

The insulating sets are available for standard ASME/ANSI B 16.5 flanges and special sizes and longer sleeve lengths are also available. Gaskets for high temperatures are also available on request. Sleeves are also available in Mylar and Polyethylene.

Phenolic RTJ gaskets available to R 60 and some BX styles.
