Specification

SEODescription

The Φ154-159 expansion tube, specifically designed as an Ordinary expansion 8x90 variant, is a robust Φ159 expansion pipe fitting engineered for industrial piping systems requiring precise alignment and thermal compensation. It features direct compatibility with standard 8-input/8-output configurations, seamlessly integrating with modular pipelines and supporting flange or threaded connections. Operating within a voltage range of 24V DC to 220V AC and temperature tolerance of -30°C to +120°C, this component excels in oil/gas, chemical processing, and power generation applications. Its compact 90mm axial expansion capacity and corrosion-resistant steel construction ensure reliable performance under high-pressure conditions. While offering exceptional durability and easy installation, its fixed expansion ratio may require supplemental joints for extreme thermal shifts. Critical interfaces include NPT and ANSI flange standards for universal adaptability.

SEOQandA_Product

question:Pipe deformation during expansion?
answer:Adjust pressure settings and ensure proper alignment of the expansion tool.
question:Uneven expansion diameter?
answer:Inspect mandrel wear and replace if worn; verify consistent heating.
question:Tool jamming mid-process?
answer:Clean debris from the expansion head and lubricate guide rails regularly.
question:Material cracking post-expansion?
answer:Use annealed pipes or reduce expansion rate for brittle materials.
question:Poor connection after expansion?
answer:Check mold calibration and ensure pipe end is prepped without burrs.
