A flanges is a poduct which is use to connect pipes, valves, pumps and other equipment to form a piping system. Flanges are usually welded or screwed type for connecting. Flanges joints are made by bolting together 2 flanges with a gasket between them to provide a seal and prevent from any leakage. Flanges facing are of different types like Raised face, flat face, Ring-Type Joint, Tongue & Groove, etc.

Stainless Steel ring type joint flanges

Duplex Flanges and Super duplex flanges are generally lower in cost, as lower percentage of alloying element is used in the manufacture of Duplex. The yield strength of 2205 Super Duplex products is higher compared to austenitic stainless steel products, as a result of which users can purchase relatively lower thickness duplex Flanges and duplex flanges.

Stainless Steel slip on flanges

Slip-on pipe flange usually slips over the pipe. Slip-on pipe flanges are typically made with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the slip-on flange to slip over the pipe. Slip-on pipe flanges are welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on pipe flanges can sometimes also have a boss/ring or hub, and can be made with a bore to suit either pipe or tube. Ring pipe flanges and hub pipe flanges are both considered slip-on pipe flanges because they both slip over the pipe.

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 are available with raised, flat or RTJ faces, and are also available in orifice configurations.

Stainless Steel Weld Neck flanges, ss welding neck flanges manufacturers

Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe.

We are well known for Stainless Steel Weld Neck flanges products. Advance technology and high quality materials are used to produce best & effective flanges. Stainless Steel Weld Neck flanges are produced in different dimension, shape and size as per the requirement of our customer.

Stainless Steel socket welding flanges, Ss Socket Weld flanges manufacturers

Stainless Steel Flanges are available in Weld Neck, Slip-On, Threaded, Screwed, Socket Weld, Lap Joint, Blind, Long Weld Neck & Orifice type. These Stainless Steel Flanges can be manufactured in size 1/2″ NPS to 60″ NPS as per different dimensional standards.

Socket weld flange is similar to the slip-on flange in outline, but the bore is counter-bored to accept pipe. Socket welding pipe flanges are typically used on smaller sizes of high pressure pipes. Socket weld flanges are widely used in high pressure systems such as hydraulic equipment and steam lines. Socket weld pipe flanges are attached by inserting the pipe into the socket end and then applying fillet weld around the hub of the flange. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. An optional internal weld may be applied in high stress applications.

Stainless Steel threaded flanges manufacturers

Threaded flanges are widely used in low pressure piping systems, as no welding is involved while connecting the flanges to pipes or other equipment. However, the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing its applications. Threaded flanges are also known as screwed flanges and are similar to slip-on flanges, but the bore is threaded to enable assembling without welding. Threaded pipe flanges are usually used with pipes that have external threads.
