Threaded Flanges

ASME/ANSI B16.5 THREADED PIPE FLANGES MANUFACTURER IN INDIA MANUFACTURER/EXPORTER OF HIGH QUALITY THREADED FORGED FLANGES CARBON, ALLOY, STAINLESS STEEL THREADED/SCREWED FLANGES

High-quality threaded or screwed flanges meeting ASME/ANSI/DIN standards are manufactured only in India by SK Tube Corporation. For common size carbon steel and stainless steel threaded flanges, we provide fast delivery options.

Because threaded flanges don't require welding to connect to pipes or other equipment, they are frequently utilized in low pressure piping systems. Even if welding the flange around the connection after assembly is possible, this isn't thought to be a good enough way to expand its uses. Similar to slip-on flanges, threaded flanges are also called screwed flanges because they include a threaded bore that makes welding not necessary for assembly. Pipes having exterior threads are typically utilized with threaded pipe flanges.

We provide organizations in a variety of industries, such as shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical facilities, and turnkey projects, with threaded pipe flanges made at our factory.

The US, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka are just a few of the nations and territories to which our items are frequently transported.
