    Description

    LS-B51M Bending Test Apparatus for Metallic and Composite Conduits is engineered to evaluate the bending performance of metallic and composite conduit systems in accordance with international and national standards. Utilizing precision-engineered fixtures, the apparatus applies controlled stabilizing forces to specimens, inducing standardized bending at specified angles and curvature radii. Post-test inspection involves visual examination for surface cracks, assessment of weld integrity, and measurement of cross-sectional deformation to determine mechanical resistance under bending stress conditions.

    The equipment operates with repeatable, standardized procedures, ensuring controlled bending processes that yield objective and reliable data for quality assurance in conduit product manufacturing and compliance verification.
