Reducing 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 Reducing flange manufacturers and supplier in India, DM Special Steel Ltd   manufacturer Reducing 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.

Reducing flanges are designed for when there is a change in the pipe size. The predominate flange (dimensions) matching the larger pipe size (NPT) but having a smaller bore matching the smaller pipe size (NPT). These flanges normally come in blind, slip-on, threaded and weld neck flanges. They are available in all pressure classes and provide a good alternative to connecting two different sizes of pipe. This type of flange should not be used if an abrupt transition would create unwanted turbulence, such as at a pump.
