Flange Insulation Kits There Are Three Main Forms

Flange insulation kit group there are three main specifications: 1.RF type flange (APS TYPE F) insulation gasket group is only applicable to the protruding face of the flange protruding flange, where the rubber gasket parts without bolt holes, Mainly by the four parts: Flange with non-bolt holes 3.0mm thick insulation pads (rubber pads), insulation sleeve, bolt hole insulation pads (phenolic resin gasket) and stainless steel washers. 2.FF Type Flanges (APS TYPE E) Flanges for insulating flanges with the same overall dimensions as the flanges with flange bolt hole washers make installation easy and convenient. Mainly by the four parts: Flange with non-bolt holes 3.0mm thick insulation pads (rubber pads), insulation sleeve, bolt hole insulation pads (phenolic resin gasket) and stainless steel washers. 3.RTJ-type flange (APS TYPE D) RTJ flange insulation gasket group for RTJ flange ring groove surface, made of reinforced phenolic resin, the size in line with ANSI and API standards, the shape of an oval and octagonal. There are BX gaskets up to 15000PSI.

Insulation Gasket Special heat-resistant material selection: Gasket: NEMA grade G7 and G10 Durabla, Durlon, Lydall, JMRD81 Casing: Nomex, NEMA grade G7 and G10, Durabla, Durlon Washer: NEMA grade G7 and G10, Durabla, Durlon The above materials are selected according to the special conditions such as the temperature of the medium carried in the flange. Insulation flange is mainly used in gas transmission and distribution lines and gas pressure regulating, metering, storage and other equipment, its main role is to gas transmission and distribution pipeline sections, equipment and pipelines insulated from each other to protect them from chemical Corrosion, extend pipeline and equipment life. Products comply with SY / T0516-1997 "Insulation Flange Design Technology" standard.

According to the different insulation seal is divided into pressure seal type insulation flange (Type I insulation flange) and self-tight sealed insulation flange

 1. Cathodic protection

In order to ensure the effectiveness of the cathodic protection of stainless steel pipes, the pipe must be divided into easy-to-handle lengths, and the use of an insulating flange kit ensures the sealing and insulating properties of the flange.

2. Isolation of static electricity

When using pipelines to transport flammable and explosive media, the use of insulated flange kits to reduce or eliminate this potential hazard should the conditions of explosion be met by static electricity, cathodic protection systems, or eddy currents.

3. Galvanic corrosion

The contact of different metals will accelerate the weak stability of the metal corrosion, this corrosion is called galvanic corrosion. Galvanic corrosion plant occurs between the metal flanges of different materials, the use of a suitable insulation flange kit can eliminate galvanic corrosion.
