Standard Flanges namely Weld-neck, Slip-on, Socket-weld, Lap-joint, Blind and Screwed Types are commonly manufactured by DINESH INDUSTRIES. Forged flanges cover a full range of pressure ratings 150 – 2500 psi for ASME & PN6-PN400 for DIN / EN flanges. As the best flange manufacturer, the non-standard flanges manufactured by us up to a diameter of 4500 mm and the weight not exceeding 5,000 kg.

One of the leading forged flange manufacturers and supplier in India, DINESH INDUSTRIES Forged Flanges Manufacturer In India various types of carbon steel, alloy steel, stainless steel and duplex steel flanges as per customer recognized material standard (ASME/ANSI/DIN). The flanges are also manufactured by us as per customer specific requirements or drawings.

Forged component flanges are mainly used on heat coupling of pipes where bending stress on the coupling, due to the expansion of section or due to other forces, is foreseen. We are an enterprising organization in the field of forged blind flange. Our aim is to provide quality products at reasonable price as per schedule and maintain good relationship with the best people in steel business. To know more for our quality of forged pipe flanges and excellent service contact us now.
