Stainless Steel Flanges Manufacturers and Exporters

Flanges Manufacturer, Supplier, and Dealer in India

Satin Steels, a reputable manufacturer of flanges in India, operates in Mumbai’s steel market. We specialize in crafting an extensive array of industrial pipe flanges, NPT flanges, and PN16 flanges ranging from ½”NB to 48”NB. NPT flanges serve as vital connectors in piping systems, facilitating connections between pipes, tees, elbows, reducers, valves, and other piping components. We highly recommend NPT flange manufacturers in India who utilize top-quality materials.

Among the flanges we produce, forged flanges, weld neck flanges, threaded flanges, slip-on flanges, and blind flanges stand out as the most sought-after types. These flanges find widespread application across diverse industries, including petrochemical plants, refineries, pharmaceutical plants, oil and gas transportation, power generation facilities, marine operations, and wastewater treatment plants. A steel flange can function as a plate for covering or sealing the end of a pipe, a configuration commonly referred to as a blind flange.
