Appearance Requirements: The surface of the tensioner shall be free of visible scratches, dents, and signs of corrosion.
Dimensional Accuracy: The dimensions of all components of the tensioner must strictly conform to the requirements specified in the design drawings.
Material Properties: The materials selected for manufacturing the tensioner must possess the requisite mechanical properties.
Tensile Strength: The tensile strength of the tensioner must satisfy the design requirements. During tensile strength testing, the tensioner shall be mounted on specialized testing equipment, and the tensile force shall be increased gradually.
Locking Function: The locking mechanism of the tensioner must be reliable. Once the tensioner has been tightened to the required force, the locking device should effectively secure the assembly to prevent any loosening.
Corrosion Resistance: The tensioner must possess a certain degree of corrosion resistance to withstand various operating environments.
Fatigue Life: Since the tensioner is frequently subjected to tensile forces during actual use, it must possess a sufficient fatigue life.
Operating Force: The force required to operate the tensioner should fall within a reasonable range.
Marking Requirements: Important information-such as the specifications, model number, and rated tensile force-must be clearly marked on the tensioner.
