Flaring tool

1. While copper and steel tubes are usually joined by soldering, brazing or welding, there are times when a mechanical joint may be required or preferred. If you connect tubes with a mechanical connection you need flaring. Flaring is a process to form the end of a tube to make a liquid-tight or a gas-tight connection. The most common flare tube ends and corresponding flare fitting standards in use today are the 45-degree SAE style, and the 37- degree AN style, also used with the JIC system. For a given size, the AN/JIC style tubing generally has a higher pressure rating SAE and AN/JIC connections 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. A copper tube used for propane, LP, or natural gas may use flared brass fittings of single 45°-flare type, according to NFPA 54/ANSI. Z223.1 National Fuel Gas Code. Nevertheless, all National Model Codes permit the use of flare fitting joints, the one should be consulted by the authority having jurisdiction are completely (AHJ) to determine acceptance for a specific application 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. Double-lap flaring usually is formed in the same shapes and meets the same specifications as the Single Flare. If you flare the tubing properly with the proper tools and right technique you’ll get the leak-proof connection 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 tool for stainless steel 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 cutting tool is used. A flaring tool kit usually consists of two main pieces – a reamer and a flare form. 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 The thing that makes the actual flaring is reamer, which has holding arms, a screw, and a conical point.
