Duplex Flanges Manufacturers in India
Alloy 2205 Blind Flanges
Duplex Slip On Flange
DDS Weld Neck Flange
Duplex Flanges connect desalination, offshore and pulp bleach piping. Chloride stress cracking rarely troubles them in warm brine. We hold half to 24 inch stock as a Duplex Flanges Supplier in Mumbai. Pressure classes run from 150 up to 2500. Duplex Weld Neck Flange suits high pressure and cyclic loading. Duplex Slip On Flange fits low pressure cooling water lines. Duplex Blind Flange shuts off spare nozzles and test points. Each piece passes PMI, and hydro testing comes on request.
Duplex only performs when its ferrite balance is right. We measure every heat with a calibrated ferrite meter. Readings must fall between 35 and 55 percent. ASTM A923 tests then rule out harmful intermetallic phases. Results go on the MTC for your inspector. That rigour ranks us among Duplex Flanges Manufacturers In India.
Desalination plants in Saudi Arabia and Oman order heavily. Offshore operators in Norway specify duplex for firewater rings. North Field expansion projects source from us as a Duplex Flanges Supplier in Qatar. Our Abu Dhabi trading partner keeps Duplex 2205 Flanges ready.
