tubes with thin walls can be bent right knee.If the pipe has a thick wall, before bending, bending place of the future must be very hot.This can be done by using a gas burner.When on-site heating pipe begins to depart scale, you can begin to bend the pipe.Steel pipes thus becoming bright red and the aluminum can be heated up to the moment when the paper, held close to it will not ignite.
However, not all of the pipe can be bent by heating in the fold.Galvanized pipe, for example, do not tolerate heat.Without using the welding machine can bend a pipe using bending tool.It can be manual or hydraulic and electric.With it, you can bend the pipe in the form of the roll, duck, st
aples or withdrawal.For bending the pipe, it is necessary to lay the long bench under the clamp end, place the fold-oiled machine with oil and fold the short end of the pipe.Pipes, crossbows bend pipe prodavlivaya it at the inflection point."Crossbow" bent metal pipes and non-ferrous metal.In automatic benders are a bit easier: just need to install on the device desired angle fold to enclose the pipe and reduce the handle.
Without bender can bend the pipe by using ploskoparapllelnoy plate.plate.It has a groove in which the tube is bent, holding a special collar.Bending so only pipes with a diameter up to 4 cm. Automatic benders are a bit easier: just need to install the device on the desired bending angle, put the pipe and reduce the handle.
Another way - to use a metal plate with holes of the same diameter.There are inserted pins, moving that you can achieve different pipe bending radius.However, this method is good for long tubes.To add a short tube, need a very large force.
To pipe is formed at the fold, fill it with dry sand, carefully seal the edges so that sand does not spill during bending.Hold the pipe in a vise so that the fold was a place away from the clutches of the lips.After the tube was heated at the fold and bend the selected method.
Another method used in bending the pipe to prevent it from breaking or addition - insert it into the bendable tube strong spring.Then to extract it, strapped to the last round of the wire.When the pipe bend, pull out the spring by pulling the wire.
Tip 2: How to bend the metal tube
Most often bent pipes need to install plumbing and heating equipment.If you find already bent pieces of pipe failed, you can make them at home, using special devices.
- - gas burner;
- - sand;
- - vise
metal by bending both tension and compression tests.To tube is not broken, and she caved in, it should be inserted in the spring, which is bent at the knee will keep the tube on its walls.Remove the spring will be pulling her long wire.
Protect pipe can, filled it with dry sand.After filling tighten pipe in a vice and heat in the place where it is necessary to perform the fold.To gripe is not lost strength, heat pipe near them.Soon the scale starts to fly away from the pipe.This means that the sand is warmed.
warmed whether pipe visually determine: steel pipe will take the bright red color.Certificate of heated aluminum tube serve the paper, which began to char for presentation to her.Galvanized pipe is , on the contrary, can not be heated to bend, as this could be disrupted its cover.
Also clutches, tubes can be bent in the pipe nip.The metal plate with small holes screwed studs.They should be rearranged in order to bend the tube has been desired shape and radius.However, not always possible to ensure that the pipe was bent exactly as it should.Above all, such a device for bending pipes of great length.
Also, for bending pipes, you can use a plane-parallel plate originally having the desired curvature.Pinch pipe in clamp and start bending it in the groove of the plate.In this device can be bent pipe diameter up to 4 cm.
With bending tool (machine Volnov) bent pipe O15, 20 and 25 mm.You can bend it pipe a retraction, ducks, staples or the roll.To this end, under the clamp bench lay the long side of the pipe, lubricate place bending machine oil and fold the short side.
bending pipe O28 mm, use a special machine for bending pipes.Install it on the desired angle of bending the pipe, and inserting it into the machine, pinch grip.Using any tool to measure the length of the pipe only after bending.The size obtained in front of him - the procurement.
