Wao-loc Instrumentations is an esteemed, ISO 9001:2008 manufacturer of Stainless Steel 304/ 304H/ 304L Flangesthat are both heat-worked and cold-worked for better hardenability. We have been persistently working on offering excellent corrosion resistance flanges to industries having numerous moist and semi-moist atmospheres.

We are manufacturers of ASTM A182 Stainless Steel 304 Slip On Flange are the most commonly used flange grade; we anneal these flanges after forging for an improved corrosion resistance to acidic behaviour in the petrochemical and pharmaceutical industry. Our DIN 1.4301 SS 304H Weld Neck Flanges are high Carbon flanges, with a tensile strength of 75 ksi empowering to take up tasks in the ship building and steel Construction Industry. We are dealers and distributors of Stainless Steel UNS30403 Blind Flanges that are famous for being self-aligned flanges and do not come in contact with the inner flowing fluid, thereby not contaminating it and thus they are useful in flanging to valves and pumps.
