Product Description

Product Description

Cathodic Protection VCS Flange Insulating Gasket for Steam

Cathodic protection and VCS (Vertical Cuttings Dryer System) flange insulating gaskets are two distinct concepts serving different purposes in industrial applications.

 

Cathodic protection is a corrosion prevention technique used to safeguard metallic structures-such as pipelines, storage tanks, and offshore platforms-from corrosion. It works by making the metallic structure the cathode in an electrochemical cell, where a sacrificial anode supplies electrons to the structure, thereby inhibiting corrosion. This technique is widely employed in the oil and gas industry to protect pipelines, offshore structures, and other equipment from corrosive damage.

 

In contrast, VCS flange insulating gaskets are designed to electrically isolate flanges in pipeline systems, preventing galvanic corrosion between dissimilar metals. By providing electrical insulation between flanges, these gaskets halt galvanic corrosion and extend the pipeline's service life. They are commonly used in the drilling industry to isolate the drill string from drilling fluid.

 

In summary, cathodic protection is a proactive technique for preventing general corrosion, while VCS flange insulating gaskets specifically address galvanic corrosion between dissimilar metals in 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.
