Detailed Product Description

1. Edge-Welded Bellows Definition:

Edge-welded bellows is the most flexible element connected with vacuum flanges or end fittings of any kind steel material at both ends. It consists of a number of mould thin metal plates or diaphragm discs, which are welded together at their inner or outer diameter / plate edge in pairs.

Edge-welded bellows has high specific expansion compensation, up to 80% of the overall length, and a very low spring rate.

2.1 Edge-Welded Bellows Function Requirements:
A Wide Varity of Movement
High Circle Life of Reciprocating Motion/Traverse
Stable Spring Constant
Insulation and the most tightness

2.2 Edge-Welded Bellows Characteristics:
Vacuum Tightness
Very High Flexibility
Very Low Stiffness
