The exhaust flex pipe connect the engine and exhaust system. It transports exhaust gases and absorbs the vibrations produced by the vehicle when driving. By keeping the exhaust system from shaking too much, the pipe helps other exhaust parts last longer.
A cracked or leaky pipe not only makes driving harder but it may also damage other parts of the vehicle. Also, if driving with a hanging flex pipe, the damaged part will noisily drag across the road surface. It can even throw out sparks that may ignite fuel vapor or fragments and can damage your vehicle’s underside.
So knowing the lifetime of the exhaust pipe and replace it in time is very important.
Usually the flex pipe should last 200,000 miles, or less than 9 months, exhaust flex pipe shall be replaced, depending on the environment & driving conditions.
If in the Mid-West where salt is used heavily on the roads, or near the ocean, or if in snowy winter, the time can be shorter.
There are some factors influencing how long the flex pipe last: material, type, flexibility. A flex pipe is consist of 4 main parts: bellow(essence part), outer side(outer braid), inner side(inner braid/interlock/without), cap(two ends). The bellow with flexibility is to absorb the vibration and decrease the noise. The outer&inner part is to protect the bellow.
For material, there are 2 choices: stainless steel 201 and stainless steel 304. Stainless steel 201 material is relatively hard, with a bit of steel, it is easier to crack and rust. While the stainless steel 304 contains nickel, it’s tough and has better fatigue resistance, also better resistance to corrosion.
In the aftermarket, stainless steel 201 is more universal used for it’s better price performance. The warranty is about 6 month. Then due to different environment and driving situation, it can be longer or shorter. While the stainless steel 304 with OE quality, the warranty can be 1 year.
For type, during the 3 types: base, inner braid, interlock types, the ones with inner sleeve can protect the bellow to make it work longer. That’s why they are popular in the aftermarket.
For flexibility, during the using, the vibration and high gas temperature will age the exhaust flex pipe and lessen the flexibility, then make it worn out to crack. So better flexibility can make the flex pipe last longer. If stainless steel 304 material and more flexible exhaust flexible pipe will last much longer to 1.5 or 2 years.
Hope the information above will help you with a better understanding about the exhaust flex pipe use and how long it can last in different situation.
T-bolt V band clamps are mainly used for solid sealing of pipe joints such as vehicles, ships, mechanical equipment, chemical equipment, oil suction, oil suction hose, dilute acid-base hose, spray hose, steel wire reinforced hose, etc. Coil spring design provides self-load compensation (constant pressure) to prevent leakage due to temperature fluctuations. Typical applications include heavy duty truck ventilation and cooling systems.
Compared with traditional bolt clamps, V-type clamps have the following four advantages:
1. Super easy to install;
2. After changing to bolt installation, the installation efficiency is greatly improved;
3. Due to the connection characteristics of the V-clamp, it can be installed in a narrow space, making the design of the connection end more compact, thereby saving space and realizing a compact design concept;
4. Due to the compact design, the weight of the assembly can be greatly reduced, which is beneficial to the lightweight of the vehicle and the improvement of fuel economy.
Automakers are now working to improve the performance of car engines. In order to meet the new exhaust emission standards and reduce the pollution of exhaust to the environment. This requires the exhaust system to work properly under high temperature, extreme corrosive conditions.
The main functions of the automobile exhaust hose are: to achieve a sealed and flexible connection between the engine and the exhaust system; to absorb the rocking displacement of the engine; to limit the engine's transmission of high-frequency vibration to the subsequent exhaust system.
When designing and manufacturing the exhaust hose, it is necessary to consider the position of the ternary converter, filter and muffler at the same time to ensure the continuous and good operation of the exhaust system.
Therefore, the exhaust hose must have corrosion resistance and good pressure resistance, which can effectively compensate for the displacement generated when the engine is working, eliminate the high-frequency vibration of the engine and the low-frequency vibration caused by uneven road surfaces, and transport the exhaust gas to 1000 ° C. Airflow noise.
A good exhaust hose can significantly improve the exhaust system, the NVH performance of the vehicle, and continuously improve passenger comfort.
Relying on Yueding's professional engineers and more than 20 years of manufacturing experience, the products can fully meet the demanding requirements of users.
The ripple of conventional compensator using qualified material 8 nickel 304, corrosion resistance, rust-proof, longer service life. We promise the part of ripple which comply with Chinese standards unit weight. But many manufactures often stretched the corrugate pipe to reduce the cost for more benefit. This approach will make the distance of ripple larger, so the capacity of squash and stretch is bad. Its affected the service life.
2.Issue spectrum test report
Products through the spectrum test before funmace, can issue the report on material according to the customize, accept the material inspection in any way.
3.High temperature resistance
We strictly customize high temperature resistance Flexible metal hose. When the temperature is less than 400 degree, we use 304 stainless steel. 600 degree use 321 stainless steel. 1000 degree use 310S stainless steel .
4.High pressure resistance
The range pressure of conventional material hosepipe is 1 -2.5Mpa. If you need high pressure type compensator, you can customize multilayer and composite corrugate pipe to enhance the resistance to high pressure.
How To Distinguish The Quality Of Metal Hose
1.Look at the appearance, the metal hose produced by a good stainless steel plate is bright in color and not easy to become black；
2. Determine the metal bellows, hold the finished product and bend it, and the good stainless steel plate has good flexibility；
3. The stainless steel wires on the steel wire mesh cover of the metal hose are ordered neatly, and it is not easy to fry the wires. This is the inspection of the metal hose production line equipment；
4. An effective method is to use a magnet to suck the metal hose, the real stainless steel plate is not sucked in.
The stainless steel plate of the metal hose refers to the steel that is resistant to weak corrosive substances such as gas, steam, water and organic chemical corrosive substances such as acids, alkalis, and salts. It is also called stainless steel. In the ordinary use of metal hoses, the steel that is resistant to weak corrosive substances is often called stainless steel, and the steel that is resistant to solvent substances is called acid-resistant steel.
Because of the difference in composition between the two, the former is not necessarily resistant to corrosion by solvent substances, while the latter is generally stainless steel. The corrosion resistance of the metal hose stainless steel plate lies in the aluminum alloy element contained in the steel. The basic aluminum alloy elements of the metal hose also include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to consider the requirements for the structure and characteristics of the stainless steel plate for various main purposes.
