Bellows Testing | Destructive and Non - Destructive

To assure the user that the product has been properly designed and manufactured; it is required for quality check and inspection of bellows performance. It requires some method of examination and testing of the product. The user may specify the kind of testing required in the acceptance criterion. Various testing being done as part of the bellows manufacturing are:

Following are the non-destructive examinations that are recommended for the quality check and inspection and testing after manufacturing.

1. Radiographic examination

2. Liquid penetration examination

3. Fluorescent penetrate examination

4. Magnetic particle examination

5. Ultrasonic examination

6. Halogen leak examination

7. Mass Spectrometer examination

8. Air jet leak examination

Following are the Destructive examination is also recommended depending upon the application

1. Pressure Testing

(a) Hydrostatic test

(b) Pneumatic tests following destructive tests are also recommended depending upon the application.

1. Squirm testing

2. Meridional yield rupture testing

3. Fatigue life testing

Externally Pressurized Expansion Joint | Flexpert Bellows

Externally Pressurized Expansion Joint Externally Pressurized Expansion Joint is the perfect solution when the expansion joint must absorb large axial movement under High Pressure. Externally Pressurized Expansion Joints Absorbs large axial movements without squirm. Eliminates main anchors. Minimum guiding required for externally pressurized expansion joints Heavy duty construction for bellow protection. The Externally Pressurized Expansion Joints provide very low turbulence to f the flowing medium due to the fact that the internal surface of pipeline itself works as the liner for this expansion joint. As the thermal expansion in externally pressurized expansion joints occur the bellows element brining the internal guide rings closer reducing the gap between them and then medium can flow through this joints as if it were not there.

Manufacturing Expansion joints (Bellows) from India

What is an expansion joint? An Expansion Joint is used in the piping system to absorb thermal expansion or terminal movement, where the use of an expansion loop is impractical. Expansion joints are in different shapes and materials. Expansion joints are rubber, metallic , Teflon joints Where are Bellows used? Bellows are located between the section of bridges, paving slabs, railway tracks, and piping system. The Expansion joints are incorporated to endure the stress Why expansion joints are used? Expansion joints are used to absorb the thermal expansion. They also can be used to absorb contraction in the cryogenic line and reduce the vibration in the piping system. They are nessccary in the system to convey high-temperature substances such as steam or exhaust gases or to absorb movement and vibration. How do you install expansion bellows in a pipe system? Apply Lubricant Insert expansion ...
