Weld Neck Flanges / WNRF Flanges

We provide one-stop solution for a wide range of steel flanges used in diverse industries. These steel flanges are used to connect pipe system of Oil fields, refinery, gasplant , power plant & Ships etc. All the flanges are manufactured in conformity with National & International Standards under strict quality control. The use of high grade steel imparts properties such as resistance to corrosion, ability to withstand temperature and pressure, high tensile strength and more. Random Material sampling and 100% inspection for dimensions and finish ensure that each flange is manufactured as per customer's requirement.
