1.Visual Inspection: Check the coupler surface for cracks, deformation, corrosion, or other defects, and verify whether bolts and nuts exhibit thread stripping or damage.
2.Mechanical Performance Testing: Includes slip resistance, failure resistance, torsional stiffness, and tensile performance, conducted using specialized mechanical testing equipment.
3.Dimensions and Weight: Measure key dimensions such as thickness, width, and height according to standard requirements, and confirm whether the weight complies with specifications.
4.Material Inspection: Analyze the chemical composition of the coupler material to ensure compliance with standard requirements.
5.Bolt Tightening Torque: For right-angle couplers and swivel couplers, verify whether the tightening torque meets the values specified in the standards.
Inspection standards primarily follow:《Technical Code for Safety of Steel Tubular Scaffolding with Couplers in Construction 》(JGJ 130-2011)、《Steel Tube Scaffolding Couplers》 (GB 15831-2016) and other relevant national standards.
