Slip on Flange

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

India's SK Tube Corporation is a specialized producer of premium slip-on flanges that meet ASME/ANSI/DIN standards. For common size carbon steel and stainless steel slip-on flanges, we provide rapid delivery options. Just-in-time programs are available for slip-on flanges made in certain stainless steel grades, nickel alloy, and alloy steel.

Typically, a slip-on pipe flange is placed over the pipe. The internal diameter of a slip-on pipe flange is normally constructed to be somewhat larger than the pipe's exterior diameter. As a result, the pipe can be covered by the slip-on flange. To give strength and stop leaks, slip-on pipe flanges are welded, typically from the inside as well as the outside. Slip-on pipe flanges can be constructed with a bore to fit either pipe or tube, and they can occasionally also feature a boss, ring, or hub. Because they both slip over the pipe, ring and hub pipe flanges are referred to as slip-on pipe flanges.

Slip-on flanges are generally preferred by users over weld neck flanges, as they are a cheaper option than weld neck flange and the fact that less accuracy is required when cutting pipe to length.

Slip-on flanges come in orifice designs and with faces that are raised, flat, or RTJ.
Slip-on pipe flanges produced at our plant are available to businesses in a range of sectors, including turnkey projects, petrochemical facilities, waste water treatment plants, paper mills, pharmaceutical plants, shipbuilding, and power generating.

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.
