What is an exhaust flex pip

The automobile exhaust flex pipe is also called automobile exhaust pipe. It is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler to make the entire exhaust system flexibly connected, thereby reducing vibration and noise, and is convenient Install and extend the life of the exhaust muffler system. It is mainly used in light cars, mini cars, and passenger cars. Its structure is a double-layer corrugated tube covered with steel wire mesh sleeve, and the two ends of the straight edge section are jacketed with snap rings. In order to achieve better noise reduction, the bellows can be equipped with a telescopic Section or net set. Material: The main material is stainless steel SUS304, the material of the ferrule and the pipe can be stainless steel or aluminized steel.

Installation and management requirements for Metal Hose

The Metal Hose consists of internal metal bellows and an external stainless steel mesh sleeve and such joints. It is used as a compensating element, sealing element, connecting element, and compensation element in various gas and fluid piping systems as well as in length, temperature, position, and angle compensation systems. They are used in aerospace, petrochemical, mining and electronics, mechanical shipbuilding, medical and health, light textile and electronics, energy and construction, and other fields. In the installation process excessive twisting, stretching and bending can cause damage to the Metal Hose and the selection of the joint pulling, and jamming, so that the selection of the joint spring loss of compensation capacity, so the correct installation is to ensure the life of the Metal Hose guarantee. Below I will give you specific instructions.

This is the list of contents：

·Installation requirements

·Installation method        

Installation requirements

(1) The Metal Hose must be checked before installation and problems must be eliminated in time.

(2) During lifting, measures must be taken to prevent damage to the Metal Hose.

(3) During installation, do not hit or tap the outer surface of the Metal Hose with hand tools. Do not use strong flanges and bolts to eliminate installation deviations, to prevent welding slag from spilling onto the hose, and to prevent mechanical wear.

(4) Metal Hose should be installed in a straight line in a free state. Do not stretch or compress it axially and place it naturally in a horizontal position. This will avoid forcible pulling, squeezing, or bending away from the mesh of the Metal Hose, which should not be subjected to tensile stress and should be kept in a free position.

(5) After installation, the height of the Metal Hose from the natural ground should be greater than its lateral displacement compensation. No brackets or supports should be provided on the Metal Hose.

(6) Pipes and Metal Hose connected to storage tanks shall be installed after passing the water test before being put into production.

(7) Metal Hose connections should be used to ensure safety without vibration, that small earthquakes are not a problem, that medium earthquakes are resistant and that large earthquakes do not leak.

Installation method              

L-type installation, more common, the overall look of neat and beautiful, reduces the length of the pipeline installation, but the axial stress generated by the pipeline will act on the Metal Hose, which will reduce the service life of the hose valve.

Z-type installation, due to the length of the pipe and the number of elbows increased, correspondingly increased the investment in the project. But the axial displacement of the pipe system can be absorbed by the pipe system itself, reducing the axial stress on the Metal Hose. This arrangement is conducive to the stability of the pipe system.

In the installation of a Metal Hose, both consider the tank settlement, temperature deformation and earthquake, and other factors generated by the lateral displacement, but also consider the various factors generated by the axial displacement, only a reasonable Metal Hose installation, to make it play its due role, to ensure the safe operation of the transmission.

How to choose the metal hose?

Talking about how to choose the metal hose:

1. Pressure: The actual working pressure of the metal hose, the nominal pressure is PN/working pressure P.

2. Medium: The chemical properties of the conveying medium in the metal hose. Determine the material of each part of the hose according to the corrosion resistance table.

3. Temperature: the working temperature and range of the medium in the metal hose; the working environment temperature of the hose. At high temperatures, the temperature correction factor must be corrected to determine the maximum allowable pressure at the working temperature to determine the correct choice of pressure level.

4. Size: nominal diameter of metal hose, joint type and size, hose length.

As a kind of flexible pressure-resistant pipe, the metal hose is installed in the liquid conveying system to compensate for the mutual displacement of the pipes or the connecting ends of machines and equipment, absorb vibration energy, and play the role of vibration reduction and noise reduction. It has good flexibility and light weight. , Corrosion resistance, fatigue resistance, high and low temperature resistance, etc.

Stainless steel metal hose is a high-quality flexible pipeline in modern industrial pipelines. It is mainly composed of bellows, net sleeves and joints. Its inner tube is a spiral or ring-shaped thin-walled stainless steel corrugated tube, and the outer mesh sleeve of the corrugated tube is woven by stainless steel wire or steel belt according to certain parameters. The joints or flanges at both ends of the hose are matched with the joints or flanges of the customer's pipeline.

The corrugated pipe of the hose is formed by high-precision plastic processing of seamless or longitudinally welded stainless steel pipes with extremely thin walls. Due to the elastic properties of the bellows contour, the hose has good flexibility and fatigue resistance, making it easy to absorb various cyclic loads of movement and deformation, especially in the pipeline system, which has the ability to compensate for large displacements. In addition to the original excellent equipment for making hoses, our factory introduced two high-precision and high-tech automatic welding and forming production lines for corrugated pipes in 2012, which greatly improved the quality of the hose and made the length of the produced hose. Restrictions to meet the needs of extra-long hoses. The nominal diameter range of the hose is DN6-1000mm, and the length is optional.

The mesh sleeve is the main pressure-bearing part of the hose installed in the pressure pipe, and it also protects the corrugated pipe. According to the pressure in the pipe and the application site, one or more layers of stainless steel wire or steel belt can be selected for weaving. The pressure range of the hose is generally PN0.6-32.0MPa, up to 42.0MPa.
