The Hydraulic Flange Spreader Series is designed for safe and efficient flange separation in industrial maintenance and pipeline applications. Featuring compact structure, automatic retraction, and anti-slip design, the series includes SWR-8, SWR-40, SWR-401, and 24T Split-type models to meet different flange spreading requirements in confined working environments.
The series includes compact hydraulic flange spreaders for routine maintenance tasks as well as high-capacity split-type spreaders for heavy-duty flange separation applications. Featuring narrow jaw designs, anti-slip mechanisms, automatic retraction systems, and high-strength forged components, these tools help operators achieve safe and precise flange opening while reducing downtime and manual labor.
Whether used for gasket replacement, flange alignment, pipeline inspection, or equipment maintenance, the Hydraulic Flange Spreader Series delivers dependable performance in confined spaces and demanding industrial environments.

Application
The Hydraulic Flange Spreader Series is widely used in oil & gas, petrochemical, power generation, marine, and industrial maintenance industries. It provides a safe and efficient solution for flange separation during pipeline installation, inspection, repair, and gasket replacement operations. Whether performing routine maintenance on process pipelines, servicing power generation equipment, separating flanges in petrochemical facilities, or supporting offshore platform maintenance projects, these tools help operators create controlled flange gaps while minimizing damage to flange faces and sealing surfaces. Their compact design and reliable spreading force make them ideal for both onshore and offshore applications where safety, efficiency, and precision are critical.
