What Is a Flange Insulation Kit?
Flange insulation kits provide electrical isolation, preventing stray currents from traveling through the pipeline as they have the ability to isolate sections of the targeted pipeline in order to improve the cathodic protection efficiency and reduce the risk of leaks.
The insulation gasket kit is installed between two bolted flanges to break the electrical flow across the joint, preventing galvanic corrosion and electrochemical reactions that cause corrosion.
Kits must be installed at specific locations in piping systems to help maintain integrity, protection, and safety.
Components of the kit can include:
- Insulating gasket
- Sleeves (for each bolt)
- Insulating washers
- Steel back-up washers.
Kits are available in various configurations to meet a range of needs, with these sealing material systems designed to fill the gap and prevent leaks and contamination, and provide electrical isolation.
Installed between flanges made from dissimilar metals, flange insulation kits electrically isolate flanges, eliminating metal-to-metal contact and preventing galvanic corrosion.
Key Components of Flange Insulation Gasket Kits
Protecting the pipeline systems, these specifically formulated kits can withstand high temperatures, high pressure, and aggressive chemical environments with flange insulation gasket kits, including:
Insulating Gasket
The insulating gasket helps to prevent metal-to-metal contact as it acts as the central sealing element.
Insulating Sleeves
Isolating stud bolts from the flange bolt holes, insulating sleeves help to protect the bolts from electrical contact.
Insulating Washers
Help to provide an electrical barrier, maintain isolation while under compression, and prevent leaks.
Steel Backup Washers
This element of the flange insulation gasket provides mechanical strength, distributing bolt loads and protecting insulating washers from crushing.
Note: All four components of the flange insulation kit must be present and correctly positioned to ensure maximum protection and efficiency.
Types of Flange Insulation Kits
The main types of flange insulation kits available include:
Full Face (FF) Kits
This is one of the most common gasket kits available. This kit ensures that the full-face gasket extends to the bolt circle with holes for each bolt, covering the entire flange face, i.e., the outer diameter matches the flange diameter, and the bolt hole openings align with the bolt pattern.
This type of kit is versatile, offers simple installation, comprehensive surface protection, and great stability. It is most suited to general service applications with flat-faced flanges or if full electrical isolation is required.
Raised Face (RF) kits
Suitable for raised flange faces only, here the gasket kit covers the raised face portion, i.e., the outer diameter is smaller than the bolt circle diameter.
This kit provides concentrated gasket stress for better sealing, making it suitable for the oil and gas industry and the petrochemical sector.
Ring Type Joint (RTJ) insulation kits
Suitable for ring-type joint flanges and high-pressure and high-temperature applications, as the gasket kit provides incredible sealing and electrical isolation.
This gasket style can be oval or octagonal in design and is most commonly found in oil and gas, petrochemical, and power sectors.
Orifice flanges
Primarily used in flow measurement systems, this type of insulation kit contains extra sealing elements on both sides, making it suitable for refining and chemical processing.
The key difference between isolation and sealing performance is that flange isolation kits are primarily designed to prevent galvanic corrosion by preventing metal-to-metal contact.
In comparison, sealing gaskets are primarily designed to provide a robust seal to prevent leaks and contamination.
Note: All flange kits should be marked with the flange size, type, pressure rating, and material grade.
Materials Used in Insulation Gasket Kits
- Phenolic – cost-effective, prevents corrosion, offers high strength, and has an operating temperature of 100 degrees Celsius.
- G10 / G11 – with a G10/G11 core, these gaskets comprise epoxy glass and laminate.
- PTFE – suitable for chemical and high temperature applications due to the resistance this material can offer.
- GRE – glass reinforced epoxy.
Material Selection Factors
It’s vital that you make the right material selection for the intended application where the gasket insulation kit will be placed.
You should always choose high-quality and certified products from a reputable supplier, taking into consideration:
- Operating temperature
- Pressure rating
- Chemical exposure
- Offshore vs onshore environments.

Applications of Flange Insulation Kits in Aberdeen
Flange isolation kits form an effective isolation barrier between flanges, breaking the galvanic corrosion circuit, preventing stray current conduction, and providing an effective seal against the risk of leaks and contamination.
Applications of flange insulation kits can be found in:
- Offshore platforms (North Sea)
- Subsea pipelines
- Refineries and terminals
- Water treatment and utilities.
Flange Insulation Gasket Kits for Corrosion Protection
Widely used across industrial industries, flange insulation gasket kits aid in the elimination of metal-to-metal contact, preventing corrosion and aiding in the cathodic protection of the piping system.
All elements of the gasket kit are made with chemical stability and dielectric properties, with minimal water absorption.
Critical in maintaining pipeline integrity systems, cathodic protection protects against flaws and degradation, both of which can be found in offshore structures.

FAQs About Flange Insulation Kits
What does a flange insulation kit do?
Spiral wound gaskets are used to prevent leaks in critical applications, often found in the oil and gas, petrochemical, and industrial power industries. They can be used in pumps, pipes, valves, and heat exchangers.
What is the difference between spiral wound and ring-type gaskets?
Ring-type gaskets are solid metal gaskets, whereas spiral wound gaskets are made up of metal strips and soft filler windings, providing more flexibility due to improved recovery under compression.
Which materials are best for spiral wound gaskets?
The standard is 316 stainless steel inner ring, with a graphite filler winding, and a carbon steel outer ring.
Can spiral wound gaskets be reused?
No, once the spiral gasket has been compressed, the gasket will be permanently deformed and therefore, unable to be used again without leaks occurring.
What standards apply to ring-type joints?
Industry standards include ASME B16.20 and EN Standards, EN1514-2.
