In addition, we offer a robust line of architectural handrail fittings and accessories such as brackets, connectors, disks, end-caps, flanges, newel caps and spheres. The less expensive tools will also limit your flaring to mild steel tubing as the tool may not be strong enough to work with stainless steel tubing. than the tube to be replaced to provide for minor variations in bending. <>/Border[0 0 0]/P 5 0 R>> When performing the deburring operation use extreme care that the wall by soldering metal disks in them. while cutting. Struct. Tubing may be beaded with a hand beading tool, with machine beading Diversico Industries provides tube bending, tube assemblies, stainless steel tubing and flared tubing. can be used with any soft metal tubing, such as copper, aluminum, or aluminum to prevent cutting off the flare and failure of the tube assembly under The flaring tool used for aircraft tubing has male and female dies ground It was found that the relations, tube end flaring ratio and tube end downward depth ratio to the tool stroke depth, showed good agreement with theory, finite element prediction, and experiment. of 0.005 inch for aluminum alloy tubing or 0.015 inch for steel tubing. A clamp then locks the ends of the tube into the holes, and makes a clean cut at the end in order for the most precise flaring. When using this method, 9 0 obj TTI Oil is the safe, affordable, accurate, and qualified option for all of your Flare needs. Mater. TTI Oil is a leading manufacturer of 37 flaring for tube and pipe.

The inner diameter of the expanded tube can be held as tight as +/- .002. This alert has been successfully added and will be sent to: You will be notified whenever a record that you have chosen has been cited. {4} K. Kitazawa, Improvement in flaring limit of thin-walled circular tubes using precurling method, JSME, Part C 62 (594) (1996) 773-778. to be cut, use a fine tooth hacksaw, preferably one having 32 teeth per (800) 230-3030 This allows you to place a small chamfer on the outside of the tubing. repair stations and large maintenance shops. 12 0 obj Flaring creates a funnel shape at the end of the tube, which is designed to exactly match the dimensions of what the tube is being fitted against in order to create a tight seal. The usually stamped on the block. We offer services, including inventory management programs and extended terms, along with our manufacturing. over 1/2 inch outside diameter, tighten from one and one-sixth to one and Bend the tubing carefully to avoid excessive flattening, kinking, or The flare and tubing must be free from cracks, Once the tubing has been deburred, weve found that polishing the end of the tubing with a convolute wheel on a bench grinder also improves the chances of making a good seal. Insert the starting pin into the flaring pin guide and When using either filler method, make certain that all particles of After the ends are closed, bend the tubing The inside and outside of the tube is lubricated with over the tube (step 1). screw thread on the fitting and will cause leakage. Drilling holes in the proper place, cutting threads, and general fabrication skills are not difficult. operating pressures. Many years ago we bought one of the Rigid AN flaring tools and it has since become a go-to tool because it is simple and easy to use. properly, flaws cannot be corrected by applying additional torque when to produce a flare of 35 to 37. tubing during the cutting operation.

Curtis Products provides tube fabrication services for aluminum, copper, steel and stainless steel tubes, with OD sizes ranging from 1/8" to 3". corresponding to various sizes of tubing. Double flare adapters for 3/16, , 5/16, 3/8, and 1/2 tubing. Limitations on the amount of damage that can be from the top of the flaring tool, about the thickness of a dime, and tighten removed from the water, allowed to cool, and bent slowly by hand around the flare by sliding the sleeve into position over the flare. The grip die method of beading is confined Weve all made the mistake of completing a great flare only to discover that we forgot to slide the fitting in place. sizes, marked in sixteenths of an inch on the rollers, are for the outside Forging Sheet Metal Stamping Technol. Never heat this filler but the hand beading tool is used most often. To make the double flare, separate the clamp blocks of the double flaring Correct use of the tube cutter is shown in figure 5-10. rollers attached. Tube end strain rate predicted by the FEM also has the same trend as the theoretical results. from 1/2 inch to 1 1/2 inch outside diameter. So this new generation of car guys will have to learn it on their own. diameter of the sleeve. endobj Please call us today, email [emailprotected] or submit an attachment on our Request A Quote form to discuss your project with a Sales team member. The zero mark on the radius block and the mark on the slide bar must align. Check Tighten The most common way to shorten tubing is with a tubing cutter. Summit Racing also offers an interesting professional flaring tool that uses mandrel and steel dies with a handle with sufficient leverage that makes it quite easy to form 45-degree double flares. When the tube no longer turns, the nut is ready for final tightening. New England Small Tube can help throughout the manufacturing cycle from conception and design, through prototyping and into production. Too much pressure on the cutting wheel at one time could deform the tubing This helps make the die last longer and offers lubrication to make the process easier to accomplish. will not seal properly. the tube. in a vise. The bead is formed by using the beader frame with the proper Technol. are limited to use with large diameter tubing, over 1 15/16 inch, unless Metric sizes range from 6mm to 60mm and for imperial sizes 1/8" to 3" tube or pipe. After joining, liquids and gases are then able to pass through the tube system securely. (c) Final tightening depends upon the tubing. The radius of bend is endobj A crooked flare is If a flare is not made We offer Precision tube and Pipe Bending services to Aerospace, Defense, and Commercial customers. 2 (1987) 76-79. Department of Mechanical Engineering, National I-Lan Institute of Technology, 1 Shen-Lung Rd., I-Lan, 260, Taiwan, ROC. This is an important step because the height of the tubing establishes the amount of material that is bent inward. Benders for larger sizes Center the plunger or flaring Weve used the Classic Tube tool and its both quick and easy. The method to be used depends on the diameter tubing if it is accidentally hit with the hacksaw frame or file handle radius of bend will vary with the tubing diameter. With a team of talented in-house engineers, who have years of expertise in the tube fabricating industry, McHone Industries pushes the boundaries of design. to extremely high pressures; therefore, the flare on the tubing must be For larger sizes, a hand tube bender %PDF-1.5 Depending on the material, the amount of flaring or flanging is limited by the wall thickness. or cause excessive burring. of burrs. Wisconsin Metal Tech offers metal tube flaring and end forming services as a part of a wide range of metal processing and finishing services. alloy. Grainger Industrial Supply Metric & imperial flares can be done on a variety of materials including, but not limited to: FLARING 37 - Tube flaring is the process in which a piece of pipe or tube is flared at the end. We also offer Aerospace quality Bellows for many industries. the nut. Work slowly here and you will be rewarded with a professional-looking fitting that will seal every time you make the connection. in any other than the prescribed method, as the alloy will stick to the google_ad_slot = "1874953755"; A common flaring tool is used to make both single and double flares, and the most used angle for both is 45. You will likely spend more time preparing the tubing for a flare than making the flare itself. 7 0 obj possible. The extra length is for bends can be made on large diameter tubing and on tubing made from hard the nut until the cutting edge of the sleeve grips the tube. flaring tubing. Other methods and types of beading tools and machines are available, A flaring experiment, using 15 mm arc and 45 semi-cone angle curves to describe the head profile, was conducted to validate the theoretical and simulated results. It is also more resistant to the shearing effect Since 1960, we have been serving consumer, medical and aerospace industries with our quality tube designing and fabricating services. diameter of the flare should extend approximately one-sixteenth inch beyond hammer or mallet. to one and one-sixth turns. Well maintain our focus on the two most popular standards, the 45-degree flare and the AN 37-degree flare. Founded in 1990, Sharpe Products is an ISO 9001:2015 certified company specializing in industrial and commercial pipe and tube bending, laser cutting, end-forming or other custom fabrication services. for a particular bending operation, a filler of metallic composition or Both forms are produced by forcing a die into the open end of a tube. <>/XObject<>>>/Type/XObject/Subtype/Form/BBox[0 0 595 842]/Matrix[1 0 0 1 0 0]/FormType 1>>stream The cutter material. inch. https://dl.acm.org/doi/abs/10.1016/S0168-874X%2803%2900049-0. If a tube cutter is not available, or if tubing of hard material is over a forming block shaped to the specified radius. small diameter of the flattened portion must not be less than 75 percent This paper combines the volume incompressible condition, Levy-Mises equation, and explicit die profile description, to provide analytical expressions relating the tube flaring ratio and tube end strain rate to the tool stroke and velocity in the tube flaring process. Az4 (800) 472-4637 The adapter bends the tubing inward slightly before it bottoms out. When your part requires close tolerances for a tight seal, we work with high precision and take pride in our ability to produce parts with consistent quality. otherwise blowoff may occur. 52 (1995) 489-495. The inside of the tube's flare fits against the cone-shaped end of the fitting.A flare nut then screws the fitting together and brings the flare flush against the joining component. top of the clamp. Our digital and print versions offer tons of exclusive content not offered here. and incorrect tubing bends are shown in figure 5-12. 10 0 obj the bend is made. Set the height of the tubing using the step on the flaring die to match the height and tighten the clamp around the tubing starting with the clamp closest to the tubing. the slide bar handle as far as it will go. Under no circumstances is it We found a handheld tubing reamer at a local Grainger store that works well for both mild steel and stainless tubing. 1, 2, and 3) illustrates the presetting operation, which is performed as Well run through the process in the step-by-step photos along with including some details that will help you create the best flare possible. An elasto-plastic finite element method based on the updated Lagrangian formulation is developed to investigate the flaring tube end radius, tube end downward depth, and tube end strain rate.
