If you need to connect steel or copper tubes together, you can do it by soldering, welding or brazing, and sometimes it’s preferred or even required to do it mechanically. To make a mechanical joint on tubes flaring is used. The process called flaring is a tube’s end forming, used for creating a gas- or liquid-tight connection.

Double-lap flaring offers additional strength for tube ends, that are subjected to more fatigue and stress. The inside surface of the flare is designed with a larger diameter, that does not interfere with system’s flow characteristics. To meet the same specifications as the Single Flare, Double-lap flaring can be formed in the same shapes.

If you flare the tubing properly with the proper tools and right technique you’ll get the leak-proof joint Firstly, you need to cut the tubing to the proper length using the appropriate tool. Secondly, don’t forget to slide the compression nut on a tubing The last thing is to use a flaring tool kit to make a flaring itself.

Most of flaring kits are relatively inexpensive and easy to find, despite the fact that different sizes of tubes require specific sets of equipment. To cut a tube the special <a href="https://www.bestflaringtool.com/best-pipe-cutter-and-tube-cutter/">best pipe cutter</a> is used. A common flaring tool kit has two main parts – a flare form and a reamer. A flare form is like a clamp with a number of holes used for various tube diameters. The tubing is firmly held by the flare form, allowing you to flare the pipe using minimum strength A reamer has a conical point, a screw, and holding arms and makes the actual flaring.

The 45-degree SAE style, and the 37-degree AN style, also used with the JIC system are the common standards for flare tube ends and flare fitting in use today. For a given size, the AN/JIC style tubing generally has a higher pressure rating SAE and AN/JIC connections are completely incompatible due to the different flare angle. The hydraulic hoses are usually 37-1/2° flare connections, and the refrigeration and air conditioning industry usually uses 45° flare connections. According to NFPA 54/ANSI. Z223.1 National Fuel Gas Code, copper tubes used for natural gas, Liquefied Petroleum, or propane may use flared brass fittings of single 45°-flare type Nevertheless, all National Model Codes permit the use of flare fitting joints, the one should be consulted by the authority having jurisdiction (AHJ) to determine acceptance for a specific application
