    Grooved pipe couplings are mechanical connectors used to join pipes in a variety of applications, providing a flexible and efficient method for assembling and disassembling piping systems.

    These couplings usually consist of two housings with washers between them and secured by bolts or nuts.

    It is used for grooved pipe connections.

    At the joint, the adjacent pipe ends are not allowed to have relative angular displacement and corresponding axial rotation.

    The two butt joints of this product are inclined grooved pipe joints.

    Standards related to grooved pipe joints generally address design, dimensions, materials, and testing requirements.

    Some common standards for grooved pipe couplings include:

    ASTM A536: This standard covers ductile iron castings for a variety of applications, including grooved pipe joints.

    ASTM A795: This standard specifies black and hot-dip galvanized (galvanized) welded and seamless steel pipe for fire protection applications and may involve the use of grooved joints.

    UL 213: Underwriters Laboratories (UL) Standard for Grooved Mechanical Joints and Fittings for Fire Service.
