ASTM A105 Flanges Manufacturer in India

ASTM A105 Flanges Manufacturer and Supplier in India

ASTM A105 Flanges are forged carbon steel flanges used to form robust connections between pipelines. It’s made from ASTM A105 carbon steel, they ensure mechanical strength and good performance at room temperatures and elevated temperatures, both in oil and gas, petrochemicals, power plants and industrial processing systems. There are several types of flanges that include Weld Neck, Slip-On, Blind, Socket Weld, Threaded and Lap Joint flanges whose size and pressure class are determined based on the requirements of the pipe system. The difference from the material is that the sizes of the flanges comply with ASME B16.5 and ASME B16.47 standards. Solitaire Overseas is an experienced manufacturer and supplier of ASTM A105 Flanges in India.
