  • Threaded pipe fittings
    Threaded pipe fittings are pipe fittings with threads. Commonly used in water gas pipes, small diameter water pipes, compressed air pipes and low pressure steam pipes. Connected with threaded pipe end to form a pipeline. Appropriate adhesives (such as thick white paint, lead monoxide glycerin adhesive, etc.) can be applied to the threads to ensure sealing.
