Insulation Gasket Kit-Lamons

1) What is Flange insulation gasket kit?

In the oil and gas and petrochemical industry, refineries and petrochemical plants with dense pipeline systems, the number of flanges used is extremely large, so the issue of sealing is always put on top to prevent leaks from the sides. flange. At the same time, the insulation of these flanges is extremely important to suppress static electricity in the pipeline that causes rapid corrosion of the metal and is dangerous for the user and the system as a whole.

An insulation gasket kit will help you ensure two key issues:
- Prevents conduction between two flanges
- Ensure the sealing properties, prevent leakage at the joint between the two flanges

2) Where are flange insulation gasket kits commonly used? 

- The gas and oil pipeline system is installed offshore, in the sea environment
- Oil refinery pipeline
- Pipelines in petrochemical plants,...

3) Assemblely Flange Insulation Gasket Kits

- Insulation gasket:

• Gasket is usually composed of 2 main parts: Retainer and Sealing. Retainers will be made of hard, high-insulating materials. The Sealing part will be made of materials with good sealing ability, resistant to the exposed environment. And both must withstand high temperatures and pressures to ensure insulation and leak resistance.
• Retainer Section Thickness: 1/8" (3.18 mm); Retainer Materials: G7, G10, G10S, G11, Phenolic
• Sealing material:

- Insulation sleeves & Insulation washers

• Insulating sleeves and washers are usually made of the same thickness as the retainer part of the gasket
• Thickness: 1/8" (3.18 mm)
• Commonly used materials: G10, G11, PTFE, Phenolic

- Metal washers

• ZPS = Zinc plated Carbon Steel
• XPS = Xylan coated Carbon Steel
• SS = Stainless Steel

Types commonly used current

Type E 

Type E is a full face gasket with the same outside diameter as the flange and precision cut bolt holes. This design facilitates proper alignment of the gasket during installation and foreign material prevents flange isolation.
 

Standard thickness 1/8"

Type F
