SEB - Single Expansion Bellows
Aflex Single Expansion Bellows allow for axial, lateral and angular deflection as well as combined movements. As SEB are unrestrained, the internal pressure from the bellows is transmitted onto the pipeline as pressure thrust (see pressure thrust page and calculator).
If the required main anchors and guides are not in place, use of a different type of Aflex bellows that restrains the pressure thrust within the assembly may be required, in that instance please contact us for bellows type recommendations. For enquiries or design queries in regard to anchors and guides please consult your pipeline designer, consultant or refer to the EJMA (Expansion Joint Manufacturers Association) standards.
