Fitwel Industries LLP is one of the popular names in Metal World in India & abroad. We are the last 30 years existing firm, indulged in manufacturing, supplying & exporting Duplex stainless steel Lap Joint Flange or Super Duplex Stainless Steel Lap Joint Flange. While using UNS s31803/s32205 Duplex LJFF Flanges or UNS s32750/s32760 Super duplex LJFF Flanges, you get some special advantages like Since the Pn16 Duplex Steel Lap Joint Flange is made from duplex grade stainless, they tend to have excellent mechanical properties like high tensile strength, good toughness, good hardness as well as good resistance to corrosion. The PN10 super dupex lap joint flange with the stub end assembly is normally used in piping systems that require regular dismantling for inspection and cleaning. These Loose flanges slip over the pipe and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).
The pressure-holding ability of the UNS s31803 Lap Joint Flange A105 is slight, if any, better as compared to Slip-On flanges. And the fatigue life for the UNS s32205 Lap Joint Flange ASME B16.5 assembly is only one-tenth that of Welding Neck flanges. The UNS s32750 Lap Joint Flange, ASME B16.5 Class 300 Lap joint flange could be used in all pressure rating environments. Loose flange is available in a full-size range.
We also offer these products at customized sizes and shapes to our respected clients. We Export Slip On Flanges in Qatar, Kingdom Of Bahrain, Saudi Arabia, Indonesia, United States, Singapore, Malaysia, Turkey, UAE, Russia, Ukraine, South Africa, Australia, etc.
