Specification

SEODescription

The Φ273 expansion joint is a robust Steel expansion 8x70 solution designed for OD273 pipe systems, offering axial, lateral, and angular movement compensation. This unit features 8-layer steel reinforcement with 70mm maximum displacement capacity, suitable for pipelines requiring high-pressure tolerance up to 25 bar. It operates across -20°C to +120°C environments, compatible with standard industrial voltage ranges (24V-240V AC/DC). The joint integrates directly with flanged piping systems without additional adapters, supporting seamless connectivity in oil/gas, chemical processing, and power generation applications. Key advantages include exceptional vibration damping and corrosion resistance, though its rigid steel construction limits flexibility in compact spaces. The maintenance-free design ensures long-term reliability in high-stress pipeline networks.
