Metal Expansion Joint

Metal Expansion Joints, also known as Bellows, are used to accommodate movement in pressurized pipe systems induced by thermal expansion, contraction, and minor vibrations. Expansion joints are developed in accordance with EJMA 10th or ASME standards, as applicable.

The manufacturing size range is from 100NB up to with pressure from 300KPa, 1000KPa, and 2000KPa.

Configurations for these are: single and tied
