NEFT Energia is based in US, India & UAE. I met their representatives at the recently concluded Wind Power India 2012 exhibition in Chennai.
NEFT Energia supplies pipes, fittings, valves, flanges, gaskets, stud bolts, etc. to multiple markets and multiple industries, including the wind energy industry. For wind power plants, they supply main shaft, tower flange, lock plates, slewing ring, rotor blade disc, gear rim, etc.
According to their website, they mention that they can supply high quality wind tower products quickly, even if demand increases suddenly. They also say that due to their domestic 'just-in-time' manufacturing and warehousing/stocking, they are able to offer competitive prices for supplies.
