We are the first company in India, manufacturing ASTM A105 Flange in high size by using German technology.
What is ASTM A105 Carbon Steel Flanges?
ASTM A105 is the standard specification for carbon steel forgings for piping applications including flanges, fittings and valve parts, etc. According to ASME B16.5 (Pipe Flange), this material is categorized into Group 1.1 which has the same pressure-temperature ratings as ASTM A216 Grade WCB, A515 Grade 70, A350 Grade LF2, A516 Grade 70, A350 Grade LF6 Class 1, A537 Class 1 and A350 Grade LF3. ASTM A105 flanges refer to forged carbon steel flanges for ambient and high temperature service in pressure systems. They can be manufactured to dimensional standards of ASME B16.5, ASME B16.47, MSS SP 44, API 605, BS 4504, EN1092-1 and L-005, etc. FitTech keeps a large amount of flanges available in stock covering flange types of welding neck, slip on, socket welding, threaded, blind, slip on plate, long weld neck, orifice and lap joint, etc.
