Insulating flanges

Insulating flanges and sets of dielectric flange isolation.

There are only two common types of dielectric insulation for flanged connections.

The first type - is insulating flange.

Manufactured in compliance with the size and standard of the compound used. In particular, this type of insulation is the most reliable and widely used. Insulation insert must be located between the two end fittings (flanges), ensures high integrity and completely prevents the passage of stray currents from one part of the pipeline to another. Typically such articles are made of materials with high dielectric characteristics as Polyamide (Kaprolon) or Teflon (PTFE). Material for making such an element should be selected in compliance with the temperature parameters of the product transfer and chemical resistance.

This product is frequently used at the berths of the oil and transshipment terminals, at the junction of the pipe and the flexible connection (hose) is used for supplying the product.  When correctly choosing a place and method of installation insulation flanges, can be in use up to 10 years. The materials from which these products are made do not react with the product or the environment, not subject to aging and resistant to UV radiation. Insulating flanges guaranteed have resistance of at least 1000 ohms.

Our company has been manufacturing insulating flanges for all diameters of flanged joints in standards "German Institute for Standardization» (DIN), «American Association standards» (ASA / ANSI), «Japan Industrial Standards» (JIS). There is also a possibility to produce parts of not standard versions.

Product Advantages:

Lack of reducing the diameter of the through wiring

Lack oscillation and no loss of working pressure

Maximum high rate of resistance (ohms)

Warranty exclusion of stray currents, when applying kerosene flow rate of up to 4.7 m / s.

All products supplied by us are manufactured on CNC equipment control system. This production guarantees maximum precision and convenience products at the further operation. Materials for the production of parts purchased only on the territory of the European Union, from world-class manufacturers. On delivery of our products, you get all the manufacturer certificates of quality for the material and certified hydrostatic test report at the maximum operating pressure.

Since we ourselves are manufacturers of insulating flanges, we are able to offer products for special performance. You have to choose a right material and technical features of your desired product!

The second type - Dielectric kits.

Also manufactured in compliance with the size and standard of the compound used. Much cheaper option comparing it with the insulation flanges. It is no less reliable and widely used. The kit consists of a dielectric gaskets, grommets, and special washers for bolts standard sizes. It is important to note that the size and length of the original screws when installing insulating kit - do not change!

The standard sleeves and insulating washers are made of caprolon or PTFE, with good dielectric properties. The insulating gasket to be installed in place of the original, can be made of different materials, and according to the customer depending on the performance and the working medium temperature.

The materials from which these products are made do not react with the product or the environment, not subject to aging and resistant to UV radiation. Insulation kits guaranteed have resistance of at least 1000 ohms.

Our company has been manufacturing insulating flanges for all diameters of flanged joints in standards "German Institute for Standardization» (DIN), «American Association standards» (ASA / ANSI), «Japan Industrial Standards» (JIS). There is also a possibility of delivery of goods is not the standard version.

Product Advantages:

Lack of reducing the diameter of the through wiring

Lack oscillation and loss of working pressure

The high rate of resistance (ohms)

The low cost of the product.

The following factors can be attributed to minuses of a Dielectric kit:

Like any other gasket, gasket insulation package can be applied just once, unlike the insulating flange. Experience in the use of dielectric kits shows that washer and sleeve may be deformed and easily spoiled already at the installation stage. We as a manufacturer of insulation kits, recommend annual testing for resistance to confirm the isolation of all elements. Once every 6 months to carry out a visual inspection of connections and at the slightest damage to replace the insulation kit or elements.

Given all the above infomation, this product is very popular and cost-effective. Widely used and complies with all regulatory requirements.

The standard sizes are always available on stock in sizes DIN and ASA.
