What is a dielectric flange kit?

What is a dielectric flange kit?

Flange Isolation Gasket Kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection. By eliminating metal to metal contact, static current is halted to prevent corrosion and aid in the cathodic protection of the pipe.

What is the purpose of insulating flange?

Insulating flanges are those flanges equipped with plastic pieces that insulate and prevent the flow of an electric current between two metal surfaces. Insulating flanges are used in cathodic protection systems to prevent electrolytic corrosion.

How does a flange insulation kit work?

Contrary to the conventional nut and bolt system of flanged joints, the insulation kit uses a stud with a washer and nut on each end of the flange joint. The insulating sleeve is then inserted into the bolt holes using one insulator on each side of the flange.

What does an isolation kit do?

Flange isolation kits are used to seal and electrically insulate flanges, thereby maintaining the integrity of piping systems. Flange isolation kits are used to seal and electrically insulate flanges, thereby maintaining the integrity of piping systems.

What is a flange kit?

A flange kit contains everything required to install a flange onto a pipe. A flange collar, gasket and connection hardware are typically included in a flange kit. Using the supplied flange ring, the pipe is fitted with a ring that is designed to match the flanged connector on the new piece of pipeline being installed.

What is flange insulation kit?

A flange insulation kit consists of one washer for each nut, one full-length insulating sleeve for each bolt, a gasket (type F, E, D, O), and thick plated steel washers for each nut.

Should flanges be insulated?

Removable Insulation Jackets for Flanges and Unions. Unions and flanges are essential connecting points in the piping system. To avoid problems with overall system functioning, it is essential to insulate these items.

What is flange insulation gasket kit?

The gasket isolation kit consists of a special gasket, isolation sleeves for all the stud bolts and nuts, and special washers. Flange Insulation kits are designed for electrically insulating the flange and act as an insulator between dissimilar metallic flanges.

What comes in a flange kit?

Kits include: a pair of flanges, hardware (nuts and bolts) and a pair of drop-in style gaskets. Flange interior is NPT(F) threaded so you can screw it onto the water line. May be used with S x MIP adapter if using PVC pipe.

What is a flange kit lighting?

Ceiling Frame Flange Kits are extruded aluminum frames that act as individual fixture T-Bar frames to support the weight of any G (grid) trim recessed fixture in drywall or plaster ceilings. The kits snap together without the use of tools.

What are insulation kits?

» Insulation kits are used to provide electrical isolation between the metal surfaces of a flanged joint, by means of eliminating any metal-to-metal contact between the flange face and fasteners.

What is insulation joint?

Insulating Joints are used on pipelines to provide electrical isolation to prevent corrosion. They provide current spreading on cathodic protection systems. They provide electrical separation between pipeline section and the adjoining neighboring structures and pipelines.

What are the different types of dielectric flange isolation kits?

Dielectric flange isolation kits are available for ASME B16.5, B.1647, API flanges of all sizes and classes, from 1/2 up to 80 inches. There are four major types of gasket isolation kits, designated as F, E, D, and O. Each type of flange kit fits flanges with specific faces (RF, FF, RTJ).

Why do you need a flange isolation gasket?

Flange Isolation Gasket Kits provide an effective seal and electrical isolation of flanges. By eliminating metal to metal contact, static current is halted to prevent corrosion and aid in the cathodic protection of the pipe.

When do you need a flange insulation kit?

FLANGE INSULATING KITS – TGCD CPI Flange Insulation Kits are typically used on offshore installations, seawater environments, chemical installations; oil refinery pipelines where the flanges need to be properly plane to prevent leakage and also must be insulated.

Why do you need a Drake flange gasket?

Drake flange protectors seal the flange internals to prevent foreign objects or debris from lodging between the flanges, forming a bridge, creating a short, and compromising the entire cathodic protection system. Ordering the correct Flange Isolation Gasket Kit requires knowing the specifications and type of service for your particular application.
