Expansion Metal Joint

Overview

Expansion metal joints are engineered metallic devices designed to absorb movement and dimensional changes in piping systems or structural components caused by temperature fluctuations or pressure variations. Typically consisting of one or more flexible bellows, these joints accommodate thermal expansion, contraction, and mechanical vibrations, helping to maintain system integrity and prevent damage in critical infrastructure applications.

Featured Specs

• Diameter. 1″ – 20″
• Pressure. PN 16, PN 2.5 – PN 64 (Opsional)
• Material Bellow. AISI 304/AISI 316/AISI321
• Temperature. -90°C + 550°C

Utility Priority

Expansion metal joints are critical in utility and industrial systems where thermal expansion, contraction, and mechanical stress can compromise pipeline or structural integrity. By absorbing movement and relieving stress, they help ensure the long-term stability and safety of systems operating under variable temperatures and pressures, particularly in power plants, oil and gas facilities, and large-scale water infrastructure.
