Clamshell expansion joint
Clamshell expansion joint
Product Overview
Clamshell Expansion Joints are specially designed two-piece (split-type) metallic expansion joints, engineered for emergency replacement or field installation around existing piping systems without disturbing the pipeline. Named after their “clamshell” appearance, these joints are fabricated in halves, allowing on-site assembly via welding or bolting — making them the go-to solution for critical shutdowns, repairs, or retrofits.They are ideal for high-pressure, high-temperature applications where operational downtime must be minimized.
