• Blind Flanges.
• Socket Weld Flanges.
• Orifice Flanges.

What is stainless steel flange?

Stainless Steel Flanges are made up of different stainless steel materials. The ASTM A182 Weld Neck Flange are made up of a super austenitic material that has good corrosion resistant properties with low carbon in its composition. The applications include utility scrubber assemblies.

What are the two main types of flanges available?

We usually consider two main families of flanges, the standard flanges and the special ones.

What is the difference between RF and FF flange?

Flat face (FF) flanges are similar to the RF flanges, but they do not have the raised area like the RF flange. Instead, the whole surface is flat. They are commonly used in low temperature and pressure environments such as pump suctions or water treatment flanges.

What is pad type flange?

Studding Outlet Flanges are usually designed to be installed in the inside or outside of vessels and tanks. A common alternative name for studding outlets is “pad flange.” To clarify, the pad flange and the studding outlet are the same part and pad flanges are not a variation of studding outlet.

What is a SORF flange?

Slip-On Raised Face Flanges (Sorf) These flanges are attached to the pipe by filler welding at the hub and at the end of the pipe inside the flanges. These are available in the wide variety of sizes and application.

What is MS flange?

View Cast Iron Flanges Price list, MS pipe Flange Manufacturer. Flanges are pipe fittings that are used to connect pipes or fittings together to perform different functions. Mild Steel Flanges are common in usage as they provide a medium range of strength and corrosion resistance in a balance.

What is blind flanges?

A blind flange is a solid flange as shown below. The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. Blind flanges, just like standard pipe flanges, can be raised face (RF) or flat faced (FF).

What is the difference between DIN and ANSI flanges?

The Difference Between ANSI and DIN DIN is most commonly specified in European countries, while ANSI is usually specified in the United States. DIN standards use metric measurements (mm and bar) to measure the valve and flange sizes and pressures.

How do you choose flange material?

When choosing the ideal flange material, refer to the standards required for your intended application, consider the pipe material that will connect to the flange, and ensure the flange material you choose is rated for the temperature and pressure it must withstand. Or, contact API International, Inc.

Which flanges require a full face gasket?

ASME B31. 1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon steel flange must be removed, and that a full face gasket is required.

What are the main types of steel flanges?

Weld Neck Flanges Their distinct feature is their protruding neck.

Which stainless steel is least magnetic?

The least magnetic steels. Stainless steel type 304, which contains 8\% nickel and 18\% chromium , along with small amounts of carbon, nitrogen and manganese make this steel nonmagnetic.

What size is pipe flange?

One common standard toilet flange size is 4×3, and this is the measurement you will find beside most flanges available at your hardware or plumbing stores. The 4×3 size refers to the two diameters in the flange pipe. The top side of the flange, which connects to the toilet, is 4 inches in diameter, while the bottom diameter of the pipe is 3 inches.

What is flange hex nut?

A hex flange nut is a fastener that incorporates both a hexagonal nut with a flanged or washer-like base, which is a wide area on the bottom of the nut that extends outward past the typical diameter of the nut.
