SS 304/304L Flange Manufacturers in India
We are a leading stainless steel 304/304L flange manufacturers and suppliers in India, with ex stock inventory of 600 tons. Stainless steel 304 flanges are used for connecting pipes, valves, pumps and other equipment to form a piping system. The use of flange provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
We are manufacturers of all types of flanges such as Weld Neck Flange, Slip On Flange, Blind Flange, Plate Flange, Threaded Flange, Socket Weld Flange, Lap Joint Flange, Tubesheet, Long Weld Neck Flange and, Anchor Flange. We specialize in producing Orifice Flange, Long Welding Neck Flanges, Expander Flange and Reducing Flange. We are manufacturers of SS 304 flanges in size range of 1/2″ (15 NB) to 48″ (1200NB), in compliance with dimensions as per ANSI B16.5, ANSI B16.47 Series A & B, MSS SP44, ASA, API-605, AWWA, Custom Drawings. Additionally, we can produce custom size flanges and rings for all our customers. As one of the leading SS 304 flange manufacturers, we stock over 80 tons of stainless steel flanges. We can deliver custom size CNC machined flanges in 7 days, and standard size flanges in 2-3 days.

What is a Flanges? What are the Various Types of Flanges?
A flange is type of fitting used to connect pipes, valves, pumps and other equipment to form a piping system. A flanged joint involves three separate components; the flanges, the gaskets, and the bolting. One of the most important advantage of using a flange is that it allows more flexibility in maintenance.
The various types of flanges include: Weld neck Flanges (WNRF), Slip-on Flanges (SORF), Blind Flanges (BLRF), Lap Joint Flanges, (SOLJ), Socket-weld Flanges (SWRF), Screwed (Threaded) Flanges, Long weld neck Flanges (LWNRF), Spectacle Blind Flanges, Spacer & Blind Flanges, Ring Type Joint Flanges (RTJ), Reducing Flanges, Raised Face (RF) Flanges, Orifice Flanges, Large Diameter Flanges, Custom Flanges, Drawing Flanges, Forged Flanges, Plate Flanges, Flat Face Flanges, etc.

What is 304 Stainless Steel? About 304 Stainless Steel
Stainless steel 304(SS304) is the most basic stainless steel known as 18-8 grade with higher chromium and low carbon content. The low carbon content restricts carbide precipitation during welding as well as minimizes its susceptibility to intergranular corrosion. Stainless steel 304L(SS304L) is an extra low-carbon variation of SS304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. Both SS304 and SS304L have excellent resistance to a wide range of atmospheric, chemical and petrochemical, and food industry corrosions. Usually, they can be used in applications with the maximum temperature of 1650°F[900°C] exhibiting good oxidation resistance.
304L alloy’s lower carbon content helps minimize/eliminate carbide precipitation during the welding process. This allows 304L stainless steel to be used in the “as-welded” state, even in severe corrosive environments.
If you were to use standard 304 stainless in the same way, it would degrade much faster at the weld joints.
Basically, using 304L eliminates the need to anneal weld joints prior to using the completed metal form—saving time and effort.
In practice, both 304 and 304L can be used for many of the same applications. The differences are often minor enough that one isn’t considered massively more useful over the other. When stronger corrosion resistance is needed, other alloys, such as grade 316 stainless steel, are usually considered as an alternative.
