General description for auto exhaust flexible pipe

1. Auto exhaust flexible pipe is the important connection parts to automobile exhaust system

2.According to the different needs, the auto exhaust flexible pipe can be configured with inner liner and interlock, it plays the role of reduction of noise from the engine.

3. product structure forms, size is complete, can meet the demand of various types of design, installed between the engine and the exhaust manifold three catalytic converters, can absorb various vibration, reduce noise, partial compensation installation and effect of thermal expansion and contraction, easy to install and prolong the exhaust system life.

4. The bellows have used of hydraulic forming technology, have good flexibility and air tightness, the main raw material is stainless steel 201 304 309S 316Ti 321 409l etc. Be able to withstand high temperature and salt corrosion, ensure the design demands on the whole life of auto exhaust system.

5. In order to facilitate the installation for maintenance services, we have designed and launched flexible pipes with nipple extension on each ends, the user could cut to length as per own needs, to ensure the installation size of the entire exhaust system.

Quality Assurance:

1. Processing of braid

Our braid products are done strickly followed our internal flow of processing, the products are in accordance with technical requirements such as: no less wire, broken wire, selfless head leakage, uniform appearance, close strict etc. for each process there’s a strict Quality Test Procedure.

2. Number of bellows:

For the same size of exhaust pipes, the number of our bellows has 30% more than that of our competitors.

The increase in number of bellows would increase the damping effect and noise reduction.

Under same operating conditions our products would greatly increase the product lifetime, reduce the use cost of owner.

3. Welding procedure

welding process has strict production process and operation guide book

welding consistent, smooth, neat

welding products without sand holes, porosity ,ensure that no leakage
