"Spiraget®" Flange Insulation Kit Gaskets are designed to combat the effects of corrosion often found in flanged pipe system. Galvanic corrosion between dissimilar metal flanges, flange insulation associated with cathodic protection of underground piping are other examples where "Spiraget®" flanges insulating Kit Gasket can be put to effective use.
The Design and selection of materials used in "Spiraget®" Flange Insulation Kit Gasket, meet the twin purpose of sealing the flanges and insulating metal parts to prevent flow currents responsible for corrosion.
We design, manufacture & supply Flange Insulating Kit Gasket in three types:
Flange Insulation Kit Gasket will comprise of:
Available for use in ANSI B16.5, API, BS & DIN Standard. In this type, the central gasket is designed to be located inside the flange bolt circle and sits fully on the raised face portion of the flange. This type of gaskets will be supplied in all the materials as shown in "Materials Used " Table below.
Available for use in ANSI B16.5, API, BS & DIN Standard. In this type, the central gasket has its outside diameter as equal to that of flange outside diameter and precision cut bolt holes. This design helps easy alignment of the gaskets during installation. Type "E" gaskets are available in Neoprene faced reinforced phenolic material or other materials as shown in "Materials Used " Table below.
Available for use in ANSI B16.5, API, BS & DIN Standard In this type the gaskets available in fabric reinforced Phenolic. Available in basic "oval & octagonal" type. This type has the contact faces with oval shape. It provides a high reliability seal. These gaskets comply with ASME B - 16.20.
