What are Stainless Steel Flanges and its Types?

A flange is the part that connects the pipe to the pipe. There are holes on the flanges and the bolts make the two flanges close. The flange is sealed with a cushion. Flange can be divided into threaded connecting flanges and welding flanges. Forged flanges make access for cleaning, repairs, modification or inspection much easier. We, Rajveer Stainless And Alloys are professional SS Flanges Manufacturer in India. We focus on national and international export product development, production and sales.

Slip on Pipe Flange

These pipe flanges slip over the pipe. They’re manufactured with an inside diameter that is slightly bigger than the pipe’s outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange. Slip on pipe flanges are typically provided with a raised or flat face.

Weld Neck Pipe Flange

These pipe flanges attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe’s inside diameter.

Blind Pipe Flange

These are commonly used for testing the flow of gas or liquid through a pipe or vessel. Blind pipe flanges also allow for easy access to the pipe in case work must be done inside the line. They are oftentimes used for high pressure applications.

Socket-weld Pipe Flange

Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe.
