What are expander flanges?

Flanges are used for a number of reasons and purposes in the piping system. They can be used in combination with other fittings such as sockets and bends. A few flanges are made to combine two functions together, like the Expander flange. It acts are an expander, in other words, it acts as a reducer when connected in the opposite direction. Instead of having a weld neck flange and a reducer, the expander flange serves the purpose without the need for an extra connection and a fitting.

Where do we use steel expander flange the most?

Stainless steel expander flanges is used mostly in compressors, pumps, and valves in any piping system. The uses are in the oil and gas, offshore and onshore pipes, pulp and paper, chemical, and water supply lines. There are specifications for the expander flanges and the flanges range from 2 inches to 30 inches. The specifications are according to the ASME, ANSI, EN, DIN, and BS standards.

What are few factors to keep in mind during the Asme b16.5 expander flange selection process?

Asme b16.5 expander flanges has the dimension specifications. You need to know the requirements of your application first. Then you need to decide on the factors that have to be in your flanges. You need to know the flanges type you want to use. If you want to use the Alloy steel expander flanges, then you have to look for the material you need. Is it alloy steel, or any other material? Then the size of the flange, classifications, bolt holes, pressure class, and any other necessary information about your needs. Oftentimes, if you present your needs correctly, your suppliers can propose the right solution to you.

How to find out the right expander flange dimensions?

A350 lf2 expander flanges of other specifications have specific dimensions. You can find out the dimension according to the specification table presented for each flanges specification. 304 stainless steel expander flange can range from ½ inch to 48 inches. To check if a flanges has the right dimension according to the standard specification, you can measure a flange manually and check against the specification table.

How to test the performance of expander flange?

A350 lf2 expanding slip on flanges or any other flange can be tested to verify the performance. There are X-ray detectors, direct reading spectrographs, magnetic particle detectors, UI transonic flaw detectors, and methods of hydrostatic testing. The Class 150 expander weld neck flanges or any other specific flange can be tested to see if they meet the specified properties. Tensile test, yield point test, bending test, and impact test will provide information to verify if the flange performs as specified; but these are destructive tests. Destructive tests are usually performed at the manufacturing level.

What is the Function of ASME B16.5 SS Expander Weld Neck Flange and How Do They Work?

Asme b16 5 expander weld neck flanges ranges from ½ inch to 48 inches. The specialty of the flanges is that they combine the functions of a reducer and a weld-neck flanges. This reduces the space needed for two components. The Stainless steel expanding weld neck flanges has only two openings and no connections in between. This means, it is stronger than a welded neck flange and a reducer connection because it would reduce an extra connection. The Carbon steel expanding weld neck flanges is made of forged metal and has an even distribution of grain pattern and tensile capacities. The flange has an expanded end which has a larger diameter than the other side, thus acting as a reducer.
