BELOCK STTEL X BRASS Dielectric Flange, For HVAC SYSTEM

We Bostan Engineering introduce ourselves as an ISO 9001:2015 Engaged in design manufacturing & Exporter of Dielectric Unions, flanges & Bimetallic flanges.
Dielectric Flange:are designed to be installed between pipes of dissimilar metals to avoid electrolysis,which leads to corrosion and pipe failure.
SIZES:
2.1/2" TO 8"
MATERIAL OF COUNSTRECTION
1) Body Mild steel Flange with EPOXY Couted2) Tailpiece-Brass3) Insulation-Nylon4) Gaskets-EPDM (Sandard), Viton (High Temp.)
OPTION
1) Boby Alloy Steel with Hot dip zinc Galvnized, SS 304 & SS & FLANGE 3162) Tailpiece-Copper3) Insulation-Taflon4) Gaskets- Viton (High Temp.)
SPECIFICATION
The Dielectric Flange fitting shall be rated for 250 PSI Also available of 300 PSI (ANSI B 16.42 OR B 16.24). Thebody and nut shall be epoxy coat, the insulator shall be nylon, the tailpiece shall be brass and the gaskets shall be EPDM RUBBER. Union and flange can be provided with any connection type ( welded,sweat, thraeded, etc) and can be made transition between different pipe size. Also available NPT threadingon request.FEATURES:
Maximum working water pressure 300 PSI, Maximum working water temperature 180°F.Threaded connection-ANSI B 1.20.1, Copper connections - ANSI B 16.22.

Why use Dielectric Unions:
It is use to Electrolytic corrosion occurs in plumbing systems that contain dissimilar metals. Copper present in heating systems is a metal that dissolves very easily. Waterborne copperparticles thus circulate in heating network and come in contact with other metals forming an electric pile phenomenon. Water and the 2 dissimilar metals form a “battery” where electric current carries ions from one metal to another causing it to dissolve.

APPLICATIONS:
Dielectric Flange can be used on all installations of heating, air conditioning, hotwater storage tanks, chilled water processing tanks, FCUs and AHUs.

ORDERING:
BOSTAN ENGINNERING is Manufacturer for several qualities of dielectric union andflange. To order the Right union and flange for your particular application indicate that you need a dielectric flange and specify the model, type, pipe thread size, and coating. An example in included to help illustrate this process.
