Flange Insulation Kits The Validity Of The

The working principle of the flange is to use the insulation flange in the insulating flange and high-strength insulation pad insulation properties of the insulation flange on both sides of the electrical insulation to work. According to the engineering practice, our insulation performance of the insulation flange according to "insulation flange design technical requirements" (SY / T0516--1997) in the relevant requirements and "buried steel pipe cathodic protection parameters test method" (SYJ23- 86), the test results show that: insulation pads and fastening bolts insulation pads in the insulation between the working surface of the resistance value to meet the regulatory requirements.

Pipeline insulation flange is mainly used in gas transmission and distribution pipelines and gas pressure regulation, metering, storage and other equipment, its main role is to gas transmission and distribution pipeline between the sections, equipment and pipeline insulation isolation, to protect it from Chemical corrosion, Flange Insulation Kits extended piping and equipment life. Products meet SY / T0516-1997 "insulated flange design technical requirements" standard.

1. cathodic protection

In order to ensure the effectiveness of the cathodic protection of the stainless steel pipe, the pipe must be divided into easy-to-handle lengths, Flange Insulation Kits and the use of an insulated flange kit ensures the sealing and insulation of the flange.

2. Isolate static electricity

When using a pipeline to transport flammable and explosive media, Flange Insulation Kits the use of an insulated flange kit can reduce or eliminate this potential hazard if explosion conditions are ignited due to static electricity, cathodic protection systems or vortex currents.

3. galvanic corrosion

The contact of different metals will accelerate the stability of the weak metal corrosion, Flange Insulation Kits this corrosion is called galvanic corrosion. The galvanic corrosion plant takes place between metal flanges of different materials, and the use of a suitable insulating flange kit eliminates galvanic corrosion.

Insulated flanges are collectively referred to as pipe flanges for both the sealing performance required for buried steel piping and the electrical insulation required for electrical corrosion protection works. It consists of a pair of steel flanges and between two flanges Insulation seals, Flange Insulation Kits flange fasteners and fastener insulation parts and with two flanges have been welded with a pair of steel short tube.

Insulating flange is an important pipeline attachment which is indispensable in gas transmission and distribution and oil pipeline system. It is mainly used in gas transmission and distribution system and gas pressure regulating station. Its role is to make the gas pipelines and gas The transmission and distribution lines are insulated from each other to protect them from electrochemical corrosion, Flange Insulation Kits prolong the service life, and can be used directly.

Insulation flange can be in the pipeline required by the medium temperature, pressure, long-term reliable work, have sufficient strength and sealing performance, Flange Insulation Kits so the insulation flange is widely used in gas transmission and distribution lines and gas pressure regulation, metering, storage and other equipment The

Insulated flanges have the electrical insulation required for the electrochemical protection of the buried pipe. Therefore, the insulating flange can isolate the equipment and pipelines from each section of the gas pipeline to protect it from chemical corrosion and prolong Pipeline and equipment life.
