ASTM A350 LF2 Forged Flange and SA350 LF3 Blind Flange manufacturers in India
FitTech Industries Pvt. Ltd. was established in 1985 and have 3 decades of experience in manufacturing carbon steel pipe fittings and flanges in accordance to ASME B16.9/ B16.11 with commitment to provide world class quality to our customers at competitive price by using innovative production system and process.
Our factory is located at Village Poman, Taluka Vasai, District Thane, Maharashtra, India. It is easily accessible through NH No.8 and 35 K.M. from International & Domestic airports. We have invested 3 million dollars (20 Million Rupees) to upgrade our factory making it of world level with high grade sophisticated production equipments producing all grades of Pipe Fittings, Butt Welded Fittings, Flanges with atomization and electric panel control with green technology.
We are the first company in India, manufacturing ASTM A105 Flange in high size by using German technology.
What is ASTM A350/A350M-07 Carbon Steel Flanges?
This specification covers several grades of carbon and low-alloy steel forged or ring- rolled flanges, forged fittings and valves intended primarily for low-temperature service and requiring notch toughness testing. They are made to specified dimensions, or to dimensional standards, such as the ASME and API Specifications referenced in Section . Although this specification covers some piping components machined from rolled bar and seamless tubular materials (see ), it does not cover raw material produced in these product forms.
