Or you might have found paper clips fascinating. The steel tube, pipe, or beam is laid out straight and the ends are pulled around the appropriate sized die to form the radius. Visit any airport or museum built in the past couple decades and count the number of curved metal structures you find.with the right equipment. As adults, we rely on curved steel beams, pipe, tubes, and angles in everything from a simple park bench to spiral staircases to some parts of modern skyscrapers. Here are four ways the construction sector bends the metal beams and pipes that support our buildings.Forming steel tubes, beams and pipes is not as hard as it looks.Table Forming SteelTable forming is the fourth process. Even as a child, you were most likely bending metal for fun..Mandrel works best when the steel tube or pipe has a heavy wall and/or requires a tight radius because it prevents the material from rippling.
The steel tube, pipe, channel, bar or steel beam is fed through the press, which applies pressure every 6 or 7 inches until the material is bent to specificationsPress is used to bend bigger, heavier beams, pipes, channels, bars or tubes (24 inches or thicker) that do not require a very tight radius. There are different kinds of rolling processes.Rolling is effective when the material metal, plastic, glass, whatever - must be bent a great deal.But if all that is too much for you, pick up those pipe cleaners and Copper Fittings manufacturers wow your kids with the colorful pipe-cleaner clowns you can form by bending metal at home.. As the mandrel moves, it bends the metal around the appropriate sized die to form the radius.Roll Forming SteelRolling is the best known way to bend metal, perhaps because it is the least costly. This method is ideal for producing steel coils, spiral staircases and the like.. This is a less common process than rolling or mandrel. Obviously, this process is of little use for bending metal beams or sheets, however, it is used in bending exhaust pipes, molten glass and in very tiny cases, jewelry.Have you ever wondered how they do it? I mean, how can you bend a steel beam and still keep the strength to support an airport roof? Well, there are four ways. Hot rolling (above the recrystallization temperature) mostly produces sheet metal. For instance, it can produce bends up to 360 degrees. Most non-ferrous metal structures are rolled cold, but steel is usually rolled hot. Rolling uses an appropriate size die that adjusts to the steel tube, angle, pipe, channel, bar or steel beam and revolves at the same peripheral speed, turning in opposite directions.Because rolling requires less set-up work and uses pre-made dies, the cost is less than other ways to bend and form steel, so companies often choose this when it suits their specifications.Mandrel Metal BendingMandrel bending is also fairly well known.Table forming is used primarily to bend smaller, heavier steel tubes, pipes, channels, bars or steel beams that require a tight radius. However, it is capable of producing large, load-bearing steel support beams used for schools, roofing, skyscrapers, gymnasiums, malls and bridges.
Mandrel can only bend steel tubing up to 180 degrees, but it produces a bend that is uniform all the way up and down the pipe or tube. Perhaps you were making pipe-cleaner clowns. As the metal passes through the roll, the machine applies pressure to bend the tubing or the beam to the desired radius. In this process, a metal shaft, or mandrel, is fitted inside the steel tube or pipe. One thing is for certain, the metal you were bending as a child was not steel beams or tubes, and it never had to be strong enough to hold up a stadium roof or a roller coaster.Press to Bend SteelThe Press method is the third way to bend metal
