Orifice Flanges at Our Factory

Standard Flanges (Weld-neckSlip-onSocket-weldLap-jointBlind and Screwed Types) are manufactured by DM Special Steel Ltd to specifications of ASME B16.5, ASME B16.47, ASME B16.48, BS EN 1092, BS 4504, API-605, API-590, MSSSP44, DIN 2632 to 2638, DIN 2576, 2642, 2527, 2566. Flanges cover a full range of pressure ratings of these specifications (150 – 2500 psi for ASME & PN6-PN400 for DIN / EN flanges). Non-standard flanges are made upto a diameter of 4500 mm and the weight not exceeding 5,000 kgs.

One of the leading Orifice flange manufacturers and supplier in India, DM Special Steel Ltd   manufacturer Orifice Flanges in various types of carbon steel, alloy steel, stainless steel and duplex steel flanges as per customer recognised material standard (ASME/ANSI/DIN). The flanges are also manufactured as per customer specific requirements/drawings.

Orifice Flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. In other words, orifice flanges are used with orifice meters. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials. All orifice flange units are supplied with the plate, pressure connection holes, and jack screws.
