Standard Flanges (Weld-neck, Slip-on, Socket-weld, Lap-joint, Blind and Screwed Types) are manufactured by Dinesh Industries 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 Long Weld Neck flange manufacturers and supplier in India, Dinesh Industries manufacturer Long Weld Neck 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.
Long weld neck flanges operate when the connection pipes need to bend or go through different directions. Due to this reason, and the high pressure that occurs, long weld neck connection forging is crucial. They should be assessed to prevent damage.Connection forging is the addition of extra long weld neck flanges to aid in better flows for the pipes.
