The structure of the shaped pipe and its use

The structure of the shaped pipe and its use

The special-shaped pipe is a general term for seamless steel pipes having cross-sectional shapes other than round pipes. Now it is widely used in various structural parts, tools and mechanical parts. Compared with round tubes, special-shaped tubes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce the structural weight and save steel. The following for everyone to say the structure and its use?

The role of car exhaust pipe

The role of car exhaust pipe

What is the role of car exhaust pipes? Let's take a look. The automobile exhaust pipe has the function of reducing vibration and noise and prolonging the life of the exhaust noise reduction system. The main material of the exhaust pipe is stainless steel. For ordinary cars, the exhaust gas of the car is under a lot of pressure when it leaves the engine, so the noise generated will drive people crazy

Classification of automobile exhaust pipes

Classification of automobile exhaust pipes

What are the classifications of car exhaust pipes? Let's take a look. 1. General original pipe. 2. Back pressure pipe (as environmentally friendly as the original factory): The principle is the same as the original factory, but the sound is better than the original factory. Most of the factory cars mainly generate the pressure to return to the cylinder according to the change of the volume of the lattice plate muffler or pipe in the pipe, once the engine catches fire.
