Every internal combustion engine needs an exhaust system. Thousands of explosions occur every minute in an engine. Therefore, it releases a lot of exhaust through a pipe to continue running properly. For two stroke engines, the amount of backpressure is very important. For typical engines, such as four-stroke engines, a straight pipe system is effective if your area allows it.
Building Straight Pipes
With a tube bender, a straight pipe is one of the simplest and easiest exhaust systems to design. The system consists of a single pipe that connects to the exhaust manifold of an engine and directs exhaust away from the engine. It does not have a muffler or baffles. Professional calls the tube “straight” because no obstructions exist within the pipe, not because of the pipe’s shape.
If you need to design a straight pipe system or if you want to sell them at your business, you need a tube bender that allows you to perform a mandrel bend.
Mandrel Bending
A mandrel bend is a popular piping method, because it does not create any type of crimping or compression inside the pipe. It is a smooth bend, so it does not compress any metal parts. The alternative is crimping the pipe, which involves bending it and creating wrinkles at the point of the bend. The mandrel is much simpler and easier to bend, but it is not effective for exhaust pipes or many other applications.
Many appliances require a mandrel bend, especially if they must move fluids. A crimped bend creates turbulence at the site of the crimping. That turbulence can alter backpressure, slow down the flow, and create added pressure as the fluid exits the pipe.
Bending pipes in a fluid manner allows you to create stunning exhaust pipes.
