    Description

    LS-B51M Bending Apparatus for Metallic and Composite Conduits is engineered for standardized mechanical testing of metallic and composite conduit systems. Utilizing precision-engineered fixtures, this apparatus applies controlled stabilizing forces to specimens, inducing bending at specified angles and curvatures. Post-test evaluation includes visual inspection for surface cracks, assessment of weld integrity, and measurement of cross-sectional deformation to determine mechanical resistance under bending stress conditions.

    The equipment operates in strict compliance with international and national testing standards, ensuring repeatable and verifiable test procedures. The bending process features precise control mechanisms, delivering objective and reliable data for quality assurance and compliance verification of conduit products.
