aircraft tubing tools

| First, this particular type of tube bending often consists of tight radius bends some of these less than 1 x D. Also, the tube bending can include high wall factors of 200 plus, and oftentimes little or no straight between bends. Two types of flaring tools are used to make flares on tubing: the impact type and the rolling type. [Figure 10A and B] Flares are frequently subjected to extremely high pressures; therefore, the flare on the tubing must be properly shaped or the connection leaks or fails. These holes are countersunk on one end to form the outside support against which the flare is formed. Should you ever need any further information then our experienced sales team are just a phone call or email away and will happily answer any questions you may have. The radius of bend is usually stamped on the block. Instructions for Rolling-Type Flaring Tools. A small amount of flattening in bends is acceptable, but the small diameter of the flattened portion must not be less than 75 percent of the original outside diameter. An AN818-4D nut fits -inch tubing, and the D means aluminum. In fact, Tools For Bendings aircraft tools are known in our shop as ACQ. Use a knife or the burring edge attached to the tube cutter. On small aluminum tubing, the designation may be stamped on the surface; but more often it is shown by a color code, not more than 4" in width, painted at the two ends and approximately midway between the ends of some tubing. The yoke is used to center the flaring pin over the end of the tube to be flared. If the code markings are hard or impossible to read, it may be necessary to test samples of the material for hardness by hardness testing. With the right tools, some practice and a big stamp on your forehead reminding you not to forget the AN818 collar, flare fittings are easy. SIOUX Mini Palm Drills - KEYLESS CHUCKS, Chicago Pneumatic Drills (Standard & Threaded), LIBERATOR KIT / LIBERATOR Hi-Lok Ratchets, JIFFY Pneumatic Hi-Lok Installation Tools, Hollow Collar Cutters-for Removing Hi-Lok Collars. The tools are self-gauging; the proper size flare is produced when tubing is clamped flush with the top of the die block. In modern aircraft, aluminum alloy, corrosion-resistant steel, or titanium tubing have generally replaced copper tubing. For the best experience on our site, be sure to turn on Javascript in your browser. LAS Aerospace Ltd is registered in England No 2041506. Scratches, abrasions, or minor corrosion on the outside of fluid lines may be considered negligible and can be smoothed out with a burnishing tool or aluminum wool. The hand beading tool works somewhat like the tube cutter in that the roller is screwed down intermittently while rotating the beading tool around the tubing. Tighten to the specified torqueassuming aluminum fittings, its 40 to 65 inch-pounds for -inch tubing, 75 to 125 inch-pounds for -inch tubing. The objective in tube bending is to obtain a smooth bend without flattening the tube. Slip yoke over the flaring bars and center over adapter. When cutting tubing, it is important to produce a square end, free of burrs. Makes smooth short radius bends up to 180. Damaged tubing and fluid lines should be repaired with new parts whenever possible. Rancho Santa Margarita, CA 92688 Connecting the tubing to the fitting requires slipping the nut and collar onto the tube, and then forming (flaring) the end of the aluminum tube to a female 37 cone. Another important factor in aircraft tube bending is ensuring the finest quality material is used. More Info, Herber Aircraft offers Rynglok hydraulic tube repair systems, which facilitate permanent repairs while tubing is still on the aircraft. 194 West Dakota Avenue | Denver, CO 80223, Copyright 2022 Tools for Bending. Automotive engineers, however, settled on 45. 2 part listings most relevant to your search. Ste. Another characteristic of aircraft tube bending is its low production with many frequent tool changes. The fittings are machined from aluminum (anodized a beautiful deep blue) or steel (gray). [Figure 9]. Next, back off the cone just enough to remove the adapter. Two types of flaring tools are used to make flares on tubing: the impact type and the rolling type. The store will not work correctly in the case when cookies are disabled. The item you've selected was not added to your cart. Cut the tube squarely and remove all burrs. [Figure 5], Hand benders come in different sizes that correspond to the tube diameter. Stock and pricing of all parts listed on this site is live, all prices exclude VAT and shipping. (adsbygoogle = window.adsbygoogle || []).push({}); Two kinds of flares are generally used in aircraft tubing: the single flare and the double flare. If a tube cutter is not available, or if tubing of hard material is to be cut, use a fine-tooth hacksaw, preferably one having 32 teeth per inch. The sizes, marked in sixteenths of an inch on the rollers, are for the outside diameter of the tubing that can be beaded with the rollers. After making the cut, polish the end of the tube with fine crocus cloth, emery paper or a Scotch-Brite wheel. In this method, the tube is filled under hot water with a fusible alloy that melts at 160 F. Double flare tool. The new Malco Ratchet Action tube cutter makes it easy to make clean cuts in tight spaces. Behind the cone are threads that will accept a nut (part number AN818 (n)(x), where n is the diameter tubing in sixteenths of an inch and x designates the material. sales@lasaero.com Make the cut about one-half inch from the flaring tool. The tool consists of a flaring block or grip die, a yoke, and a flaring pin. You have entered an incorrect email address! Anneal brass, copper, and aluminum by heating to a dull red and cool rapidly in cold water. East - Peachtree City, GA [Figure 3] This tool is capable of removing both the inside and outside burrs by just turning the tool end for end. Steel fittings are often preferred on engine cases and sumps, but most of the time fittings within the airframe will be aluminum. The tools are self-gauging; the proper size flare is produced when tubing is clamped flush with the top of the die block. A new piece of tubing should be cut approximately 10 percent longer than the tube to be replaced to provide for minor variations in bending. What could be more fun? Flares soft copper, aluminium and For making up to 90 and offset bends. When using either filler methods, make certain that all particles of the filler are removed. Turn the feed screw down firmly, and continue until a slight resistance is felt. The cutter can be used with any soft metal tubing, such as copper, aluminum, or aluminum alloy. This is necessary to prevent cutting off the flare and failure of the tube assembly under operating pressures. Other methods and types of beading tools and machines are available, but the hand beading tool is used most often. Northeast - Harrisburg, PA Any slight angle will make if difficult to start the nut, and if you do get it started, you run the risk of splitting the aluminum flare. In the case of attachment to a hose, it may be necessary to bead the rigid tube so that a clamp can be used to hold the hose onto the tube. Just as time is natures way of keeping everything from happening at once, the tube is natures way of getting gases and liquids from one place to another without a mess. Deburr both the inside and outside of the tubing to be flared. If a flare is not made properly, flaws cannot be corrected by applying additional torque when tightening the fitting. Terms & Conditions, Copyright 2022 Tools for Bending. Next, back off the cone just enough to remove the adapter. Final tightening depends upon the tubing (step 3). (Somewhere, long ago, aircraft engineers concluded that 37 was the magic, non-leaking angle. It is also more resistant to the shearing effect of torque. This bells out the end of the tubing. After cutting the tubing, carefully remove any burrs from inside and outside the tube. The production CNC tube bender is an example of this type of machine. Do not use with corrosion-resistant steel or titanium. Place the fitting in a vise (step 2), and hold the tubing firmly and squarely on the seat in the fitting. Under no circumstance is it permissible to use an automotive-type flaring tool that produces a flare of 45. The best tool for flaring the tube is the rotary flaring tool. Getting a torque wrench onto fittings is usually difficult and often impossible, so an alternative method is to tighten the nut as tightly as possible by hand, and then use a wrench to tighten it once more flat. Kitplanes.com and the Kitplanes logo are protected properties under international copyright law. This is used for cleaning the burr left by the cutter on the inside of the tubing. Cut the tube squarely and remove all burrs. The hand beading tool is used with tubing having 14" to 1" outside diameter. Limitations on the amount of damage that can be repaired in this manner are discussed in this site under Rigid Tubing Inspection and Repair. If a fluid line assembly is to be replaced, the fittings can often be salvaged; then the repair involves only tube forming and replacement. Portable hand swage tools are used for tube repair, l Southwest - Chandler, AZ Standard bend radii to which bending tools form the various sizes of tubes, Figure 8. A double flare is used on soft aluminum alloy tubing 38 outside diameter and under. If the tubing is small and made of soft material, the assembly can be formed by hand bending during installation. In some cases, to resist vibration and allow relative movement, tubes take the form of flexible hoses. Insert tubing between the segments of the die block that correspond to the size of the tubing to be flared. After removing the adapter, advance the cone directly into the belled end of the tubing. To ensure consistent tubing dimensions and characteristics, all material required for a tube bending job should be procured from one supplier and should preferably be from the same lot or heat number. Fax: 800-329-3020, West - Corona, CA A crooked flare is the result of the tubing not being cut squarely. Always read the tool manufacturers instructions, because there are several different types of rolling-type flaring tools that use slightly different procedures. The use of a saw decreases the amount of work hardening of the tubing during the cutting operation. Advance the clamp screw against the end segment and tighten firmly. The tube can also be closed by flattening the ends or by soldering metal disks in them. The typical mistake is to push too much tubing into the flaring tool (bypassing the little finger). In addition to other classifications or means of identification, tubing is manufactured in various wall thicknesses. An easy way to hold small diameter tubing, when cutting it, is to place the tube in a combination flaring tool and clamp the tool in a vise. On at least one end is a male cone, with an included angle of 37. This is not a difficult operation, but it must be done in the correct order with the right tools. Slip yoke over the flaring bars and center over adapter. And properly made, they can last the life of the airplane. In addition you can search our entire inventory of over 125,000 part numbers. It works well enough on larger sizes, but at sizes of less than about inch its usually best to use a deburring bit. With a steady motion, pull the form handle until the zero mark on the form handle lines up with the desired angle of bend, as indicated on the radius block. Phone: Slip the fitting nut and sleeve on the tube. Flareless tube assemblies should be preset with the proper size presetting tool or operation. The most common connection for fuel, vent and brake lines is a single-flare fitting. USA. To prevent thinning out of the flare wall, do not overtighten. Address: After the bend is made, the alloy is again melted under hot water and removed from the tubing. First, make sure fittings and tubes are matched for size. You can edit the text in this area, and change where the contact form on the right submits to, by entering edit mode using the modes on the bottom right. The wall thickness is printed on the tubing in thousandths of an inch. Put a drop of light oil or a dab of Boelube on the cone of the flaring tool. The radius blocks are so constructed that the radius of bend varies with the tube diameter. Other problems could arise from ragged or crooked cuts on the end of the tubing or failing to clean the tube properly. Tools For Bending specializes in aircraft tube bending and can ensure the proper bending tools and processes are being used. Advance the cone downward until the shoulder of the adapter rests on the flaring bar. Although identification markings for steel tubing differ, each usually includes the manufacturers name or trademark, the Society of Automotive Engineers (SAE) number, and the physical condition of the metal. Although the use of flareless tube fittings eliminates all tube flaring, another operation, referred to as presetting, is necessary prior to installation of a new flareless tube assembly. Use these tools only to flare soft copper, aluminum, and brass tubing. Corrosion-resistant steel tubing, either annealed CRES 304, CRES 321, or CRES 304-18-hard, is used extensively in high-pressure hydraulic systems (3,000 psi or more) for the operation of landing gear, flaps, brakes, and in fire zones. When the tube hits the stop, close the top of the tool and tighten the clamp. All rights reserved worldwide. The flare and tubing must be free from cracks, dents, nicks, scratches, or any other defects. So the four necessary pieces are the fitting, the nut, the collar and the tube.

This bells out the end of the tubing. Select the hole in the flaring bar that matches the tubing diameter and place the tubing with the end you have just prepared, extending above the top of the bar by a distance equal to the thickness of the shoulder of the adapter insert. All orders are subject to our standard terms and conditions. The inside and outside of the tube is lubricated with light oil to reduce the friction between the rollers during beading. Store the fusible alloy filler where it is free from dust or dirt. Special chipless cutters are available for cutting aluminum 6061-T6, corrosion-resistant steel, and titanium tubing. Cut off the end of the tubing, if it appears damaged. Be sure all filings and cuttings are removed from the tube. [Figure 7-10]Figure 7-10. The solution is to install fittings that will allow fluids to pass, run the tubing between them and fasten the tube to the fitting with a threaded fastener. When the tube no longer turns, the nut is ready for tightening. This will permit their separation. [Figure 7-7 (A and B)] Flares are frequently subjected to extremely high pressures; therefore, the flare on the tubing must be properly shaped or the connection will leak or fail. The industry standard Rol-Air is the choice of professionals. [Figure 1]. But as you approach the 2022 Kitplanes.com. Aircraft Mechanic School Study Supplement for Future Aviation Maintenance Technicians. The ordinary production tube bender accommodates tubing ranging from 14" to 112" outside diameter. Excessive flattening causes fatigue failure of the tube. [Figure 15] The bead is formed by using the beader frame with the proper rollers attached. But where flexibility isnt required, theres no need for heavy and expensive hoses. No movement of the sleeve pilot, except rotation, is permissible. Mate the flared end of the tube with the conical end of the fitting. You will probably see some tiny stretch marks, but there should be no cracks or splits. +44 (0)1837 658080 Tubing may be beaded with a hand beading tool, with machine beading rolls, or with grip dies. We are also the UK and European distributor for Aircraft Spruce and Speciality, with whom we have been doing business with for over 25 years. To determine this point, slowly turn the tube back and forth while tightening the nut. After sawing, file the end of the tube square and smooth, removing all burrs. The yoke is used to center the flaring pin over the end of the tube to be flared. Too much torque will simply crush and split the aluminum flare. Advance the clamp screw against the end segment and tighten firmly. [Figure 13].
