Manufacturing note
Nascent fittings INC is a leading Manufacturer and Exporter of high-quality Slip on Flanges that are required while disassembling a pipe joint. Slip-on flanges are very common and are available in a large range of sizes to accommodate systems with higher flow rates and throughout. Simply match the flange to the outer diameter of the pipe you intend to connect. Installation is slightly more technical as you’ll need fillet weld both sides to secure the flange to the pipe. A slip-on flange is connected to the pipe or the fittings by two fillet welds, one executed inside and one outside the cavity of the flange. The bore size of a slip-on flange is larger than the outside diameter of the connecting pipe, as the pipe has to slide inside the flange to be connected by the execution of a fillet weld. Slip-on flanges are also defined as “Hubbed Flanges” and they are easy to recognize due to their slim and compact shape. Slip-on Flanges are available in a variety of materials, including Alloy Steel, Carbon Steel, LTCS, Nickel, Monel, Inconel, Hastelloy, Aluminium, Copper & Nickel, Stainless Steel etc.
Typical applications
- Industrial piping and process systems using Stainless Steel Flanges
- Project supply of Stainless Steel Flanges for oil & gas, power, chemical and general industry
