Stainless Steel Flanges
A flange is a forged or cast steel ring used to join pipe sections mechanically or to connect pipe to a pressure tank, pump, valve, or another piece of equipment. Stainless Steel Flanges are made from a variety of stainless steel components. A number of stainless steel components are used to make stainless steel flanges. Flanges made of stainless steel are easy to examine, clean, and change. 
The chemical composition and mechanical qualities of stainless steel are used to grade it. The most common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600, 900, 1500, and 2500. Stainless Steel Flange is denoted as SS Flange.
Viha Steel & Forging is a leading Stainless Steel Flanges Manufacturer in India. We have all types, shapes, sizes, the thickness of Stainless Steel 1.4301 Flanges in India. We are an ISO 9001/2015 certified company. 
Why Choose Stainless Steel Flanges?
Stainless ...
... Steel flanges are essential in industries Homes and buildings, Transport materials, Automotive industry. It also provides several benefits:

Corrosion and stain resistance:

Stainless steel flanges perform well in a variety of climatic conditions and with several corrosive media. When exposed to warm chloride conditions, it resists pitting and crevice corrosion. Additionally, it is resistant to corrosion that occurs at temperatures below around 60°C.

Material Benefits:

Stainless steel is strong and resistant to pressure. The combination of corrosion resistance with high strength allows a reduction in flange weight and thickness. 

Versatility and strength:

To enhance the corrosion-resistant qualities of stainless steel, other elements can be added, including nitrogen, molybdenum, and nickel. Flanges made in accordance with ASTM A182 may withstand high temperatures and retain their strength up to approximately 800°C.

Environment-friendly:

You can use stainless steel in all types of water. Applications include drinking water in public supply. The flanges have excellent resistance to the full range of potable waters, including various chloride levels. Stainless steel is one of the low-maintenance metals because of its non-corrosive properties. It is unlikely that it needs a replacement for decades.

Economic benefits:

Stainless steel flanges are low maintenance and do not have an additional coating for outdoor and indoor applications. The expected lifetime of a stainless steel system is for more than 50 years. It helps in reducing the maintenance, replacement, and downtime costs over the life of the installation.
Types Of Stainless Steel Flanges:
1. Stainless Steel Slip-On Flange
A slip-on flange is a ring that is fitted over the pipe end, with the flange face extending far enough from the pipe end to allow a weld bead to be applied to the inside diameter. Viha Steel & Forging may be an Indian supplier of ANSI B16.47 Slip On Flanges in India.
2. Stainless Steel Long Weld Neck Flange
Long weld neck flanges can be employed in both high-pressure and high-temperature industrial applications. It is similar to weld neck flanges, with the exception that the neck is extended and serves as a boring extension. We manufacture Long Weld Neck Flange with top-quality materials in different sizes according to the client’s requirements.
3. Stainless Steel Weld Neck Flange
A welding neck flange has a long tapered hub on which a pipe may be welded. This flange is often utilised in high-pressure and high/low temperatures.
4. Stainless Steel Blind Flange
The blind flange is essentially a flange without a hub or a drilled centre. Blind flanges have a flange-like face thickness, a matching face type, and a bolting pattern that is comparable to that of a flange. It can also be employed to seal a pressure vessel's nozzle opening.
5. Stainless Steel Lap Joint Flange
A lap-joint flange is a two-part assembly with a stub end that is covered by a lap-joint ring flange. This kind of flange connection is very suitable for flanges that are huge or difficult to change.
6. Stainless Steel Threaded Flange
Stainless Steel Threaded Flange is circular with Female NPT threads in the centre and cutouts for bolts. Pipes with exterior threads are utilised with threaded flanges. 
7. Stainless Steel Companion Flange
Stainless Steel Companion Flange is a pipe flange that is internally threaded to accept a pipe length and drilled to allow bolting to another such flange or sometimes: a similar setup for connecting two shaft components
8. Socket-Weld Flanges 
Socket-weld pipe flanges are typically used on smaller sizes of high-pressure pipes. The pipe is inserted into the socket end of these pipe flanges, and the top is filled with fillet welding to secure it. This makes it possible for a smooth bore and smoother gas or liquid flow inside the pipe.
9. Stainless Steel Orifice Flange
Orifice flanges are disc-shaped flanges having a Raised Face or Ring Type of Joint face. We only make and supply ASTM | ASME | ANSI Orifice Flanges that have been thoroughly tested.
