  • Product Description
  • Threaded fittings are a type of fittings with threads, mainly used in pipeline systems to assemble and connect pipes through threaded connections. Threaded fittings are commonly used for small diameter pipelines, such as water and gas pipes, small diameter water pipes, compressed air pipes, and low-pressure steam pipes. They are connected to threaded pipe ends through threads to form pipelines. To ensure sealing, appropriate adhesive such as thick white paint or lead monoxide glycerin adhesive 12 can be applied to the threads.

    Types and uses of common threaded fittings

    Single head threaded short section: a short section used to connect pipes, usually used for connecting small diameter pipes.

    ● Flat head outer thread: a short pipe with external threads, used to connect other pipe fittings with internal threads.

     Double headed threaded short section: a short section with threads on both ends, used to connect two pipes or other threaded fittings.

    ● Hexagonal head pipe plug: A pipe plug with a hexagonal head, used to seal pipes or serve as a connection point.

    ● Square headed pipe plug: A pipe plug with a square head, used to seal pipes or serve as a connection point.

    ● Round headed pipe plug: A pipe plug with a round head, used to seal pipes or serve as a connection point.

    ● Threaded pipe cap: A pipe cap with threads used to seal the end of a pipeline.

    ● Threaded four-way: used for diverting or merging pipes in four directions.

    ● Threaded elbow: used to change the direction of pipelines.

    ● Threaded tee: used for diverting or merging pipes in three directions.

    Standards and materials for threaded fittings

    The standards for threaded fittings mainly include ASME B16.11, which specifies the size, pressure rating, and material requirements for threaded fittings. Common materials include gray cast iron, malleable cast iron, cast brass, bronze, forged alloys, and carbon steel. There are four pressure levels, including Class 2000, 3000, and 6000.

    Application scenarios of threaded fittings

    Threaded fittings are commonly used in low-cost, non harsh piping systems, such as domestic water, fire protection pipelines, and industrial cooling systems. Due to their simple connection method and low cost, they are suitable for pipeline connections in these situations. ‌
