Flanges

Buy affordable flanges online only at Emechmart

Flanges are the second most commonly used to join method after welding, providing a reliable way to connect piping systems to various instruments, valves, and other components of virtually any processing system. The use of flanges increases flexibility while maintaining the piping system and allows easier disassembly and better access to system components. You can buy pipe flange types online at Emechmart that are designed to enhance flexibility.

Generally, flange available at Emechmart consists of three parts:

·   pipe flange

·   sail rope

·   screw

In most cases, some gasket and bolting materials are made from the same, or materials approved as, the piping components you wish to connect. Stainless steel flange is the most common. However, flanges are available in a wide range of materials, so it is important to tailor them to your needs. Other common flange materials include Monel, Inconel, Chrome Moly, and many more, depending on the application. The best types flanges used piping depends on both the system in which you want to use the flange and your specific needs.

Best types of flanges and their features

Flanges are not a one-size-fits-all solution. Sizing aside, matching the ideal flange design to your piping system and intended use will help ensure reliable performance, long service life and the best value. Here is a look at the most common flange types available and you can buy stainless steel flanges online from our online store.

Threaded flange

Also known as a screwed flange, this style of flange has a thread inside the bore those mates with a matching male thread on the pipe or fitting. The threaded connection means you can avoid welding in many use cases. Simply match the threading to the pipes you want to connect.

Socket-weld flange

Ideal for small pipe diameters in low temperature and low pressure conditions, socket-weld flanges feature a connection in which you insert the pipe into the flange and then secure the connection with a single multi-pass fillet weld. Avoiding the limitations associated with threaded ends makes this style easier to install than other welded flange types.

Slip-on flange

Slip-on flanges are very common and are available in a wide variety of sizes to accommodate systems with high flow rates and throughputs. Simply match the flange to the outside diameter of the pipe you want to connect. Installation is a bit more technical as you will need a fillet weld on both sides to secure the flange to the pipe.

Lap joint flange

Featuring a two-piece design, lap joint flanges require butt welding of the stub ends of the pipe or fitting with the use of a backing flange to form the flanged connection. This design makes this style popular for use in systems with limited physical space or systems that require frequent breakdowns and maintenance.

Pipe flange

Like lap joint flanges, these flanges require butt welding for installation. However, their integrity, performance in systems with many repetitive turns, and their ability to be used in high pressure and high temperature systems make them a prime choice for process piping.

Blind flange

Used to terminate or separate piping systems, buy blind flange online that are essentially bolt able-blank discs. When properly installed and combined with a suitable gasket, they can achieve an excellent seal that is easy to remove when necessary.

Special flange

The flange types listed above are the most common. However, a range of additional special flange types are available to suit a range of uses and environments. Other options include nipple flanges, weld flanges, expansion flanges, orifices, long weld necks, and reducing flanges.
