Single, double, and triple pipe joints are common connecting fittings in piping systems, used to achieve branching connections in pipelines. They are classified as follows:
Single-way: Usually refers to a one-way connected pipe joint, used for connecting or branching a single pipe.
Double-branch: refers to a pipe joint with two branches, used to achieve the branching connection of two pipes.
"Three-way" refers to a pipe joint with three branches, used to achieve the branching connection of three pipes, commonly found in drainage systems, pneumatic systems, etc.
