Standard About Insulated Flange

Insulated flange is a device used to connect two flanges in a pipeline system. Its main feature is to add an insulation layer between the flanges to prevent heat, current, or other forms of energy from conducting at the flange connection point.

This design helps to reduce energy loss, improve system safety, and is suitable for applications that require prevention of medium leakage, insulation heat, or electrical insulation.

Main features and functions:

1.Insulation material: Insulation flanges usually use materials with good insulation performance, such as rubber, plastic, or fiberglass, as the insulation layer. These materials can effectively isolate energy conduction such as heat and electricity.

2.Preventing energy conduction: The main function of insulated flanges is to prevent energy from conducting at the flange connection point. This is very important for thermal insulation, electrical insulation, or other energy insulation in pipeline systems.

3.Prevent medium leakage: The insulated flange forms a sealed insulation layer between the flanges, which can effectively prevent medium leakage in the pipeline system and improve the safety of the system.

4.Suitable for different temperatures and pressures: The insulated flange design is flexible and can adapt to use under different temperature and pressure conditions. This enables it to play a role in various industrial applications.

5.Easy to install and maintain: Insulated flanges typically have a simple structure, making them easy to install and maintain. This helps to improve the operational efficiency of the pipeline system.

6.Widely used: Insulated flanges are widely used in pipeline systems in industries such as petroleum, chemical, power, and heating, especially in situations where insulation capacity is required.

Rigor test

1.  Insulating joints and insulating flanges that have passed the strength test should be tested for tightness one by one at an ambient temperature of not less than 5°C. The test requirements should be in accordance with the provisions of GB 150.4.
2.  The tightness test pressure should be stable for 30 minutes at 0.6MPa pressure and 60 minutes at design pressure. The test medium is air or inert gas. No leakage is considered qualified.

It should be noted that different insulated flanges may be suitable for different environments and working conditions. Therefore, when selecting and using insulated flanges, it is necessary to make appropriate choices based on specific application requirements and the working conditions of the pipeline system.
