API 7K Certified Safety Clamps for Tubular Operations

API 7K Certified Safety Clamps for Tubular Operations

API 7K certified safety clamps are engineered to provide secondary securing measures during tubular handling, delivering reliable grip retention under demanding rig floor conditions. Manufactured from high strength alloy steel with quench and temper heat treatment, these clamps maintain structural integrity under repeated high torque cycles and heavy duty loads. Available in WA and MP series, each configuration is designed for specific operational needs.

    WA Series Safety Clamps

    WA Safety Clamps: Used for handling flush joint pipes and drill collars, preventing accidental tubular drops during make-up or break-out of drilling equipment.

    Safety Clamp Features

    1.High strength alloy steel with controlled heat treatment for optimal toughness and wear resistance.
    2.Multi-link chain structure distributes radial load evenly, reducing stress concentration and surface damage on tubulars.
    3.All clamps undergo proof-load testing and dimensional verification to ensure API Spec 7K compliance.
    4.Adjustable configurations accommodate a wide operational range without sacrificing grip security.
