Product Description

Type D Flange Insulating Gasket Kits for High Temperature Service

Type D Flange Insulating Gasket Kits for High Temperature Service are a type of gasket kit used in pipeline systems for high-temperature applications to provide electrical insulation and corrosion protection at flange connections. These gaskets are designed to fit type D flanges, which are typically used in high-temperature pipeline system applications.

The Type D Flange Insulating Gasket Kits are made from materials that are designed to withstand high temperatures and pressures, such as mica, ceramic, or vermiculite. These materials have excellent thermal and electrical insulation properties, which help to prevent galvanic corrosion and extend the life of the pipeline system.

The kit typically includes insulating sleeves, insulating washers, insulating nuts, and insulating bolts in addition to the gaskets. These components are also designed to withstand high temperatures and pressures, and they work together to electrically isolate the two flanges and prevent galvanic corrosion.

In summary, Type D Flange Insulating Gasket Kits for High Temperature Service are specialized gasket kits designed for high-temperature pipeline applications. These kits include gaskets, insulating sleeves, washers, nuts, and bolts that provide electrical insulation and corrosion protection at type D flange connections in high-temperature pipeline systems.

We provide a service, manufacturing to our customers requirements. We make the gasket that you need, to meet your specifications in the most economical way. We can manufacture from sample, technical drawing, or electronic file. Our production machinery can manufacture straight from your own technical drawing file.

Insulating Gaskets are used for sealing and isolating flanges to prevent corrosion. They are used for dissimilar material flanges and cathodic protection piplines to control losses due to corrosion. They can be sued to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems. 

Insulating Gaskets Types:

Type E (full face) insulating gasket provides complete protection of both flange faces. The gasket has same outside diameter of flanges. This feature will prevent collection of foreign matter between the flange faces to ensure complete cathodic isolation. 

Type F (ring gasket) insulating gasket is manufactured to fit only the raised face surface of the flanges. Outside diameter of the gasket is desinged to be slightly less than the inside diameter of the bolt circle. It it recommended that the flanges be wrapped to prevent foreign material from shorting out the flanges.

Type D Isolating Gaskets are available for RTJ flanges, the common material is phenolic and GRE.
