Bellows Testing | Destructive and Non - Destructive in India

 Bellows Testing | Destructive and Non - Destructive

Hydro Testing

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

What are metallic bellows and types of Bellows?

  What are metallic bellows? The main element of the expansion joint, which consists of one or more convolutions, is called bellows .  The performance of the bellow depends upon the geometric bellows. Hence the type of raw material and its properties, its geometric features, other influencing designing factors, construction or manufacturing method, and performance testing bellows are necessary to study. What are the types of bellows? Formed Bellows These types of Expansion Joint  used in the low-pressure system they are cost-effective and can be a substitute to the system Fabricated Bellows Formed from a thin wall tube, formed bellows contains only longitudinal welds, and exhibits significant flexibility Formed Bellows  shapes are made from single or multiply plies of suitable material (usually stainless steel) ranging in thickness from .004" to .125" and greater, and in diameter of 3/4 to over 12 ft

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.
