What Is a Coupling Plug?
A coupling plug is used to connect pipes when laying piping, especially for smaller pipe sizes. They are generally used for fluids such as air, steam, water, and oil.
They are available for hoses, steel pipes, and copper pipes, and are available in various shapes and types.These include, straight, 90-degree bend, T-shape 3-way, and closed, as well as screwed, one-touch connection, plug-in, and barbed (jagged outer shape to make it difficult for the connecting tube to come loose) types of connection methods.
Uses of Coupling Plugs
Miniature pipe couplings are a type of coupling plug used to connect pipes or tubes or fittings together, and are used in a variety of situations when laying piping, just like ordinary couplings.
They are widely used in the food and chemical industries, as well as in nuclear power facilities and manufacturing machinery, and include elbows, nipple unions, tees, bushings, reducers, plugs, and others.
Applicable tube outer diameters range from ø3.2 to ø6 mm, and connection thread sizes are M3, M5, or Rc 1/8.
Principle of Coupling Plugs
Coupling plugs are important parts used to connect pipes (tubes) to each other, fittings to each other, pipes to fittings, or equipment and devices without leaking fluid in the piping. They are also used as general fittings, and to lay out the entire piping system.
The barbed or tapered pipe threads are used to join coupling plugs to pipes (tubes). There are also couplings of one-touch structure of which the tube can be easily connected to the miniature pipe coupling plugs, and some types can be connected without tools, allowing for easy connection and disconnection during installation and maintenance.
The material of the fittings (mainly the body in direct contact with the fluid, etc.) is stainless steel or free-cutting brass steel (some are electroless nickel-plated), and it is important to select a fitting that meets the needs of the Uses of the fluid and the environment in which it will be used, such as corrosion resistance, pitting corrosion resistance, and grain boundary corrosion resistance.
In addition, when the connection method is the taper-threaded type for pipes, the joints and piping cannot be oriented freely because the threading depth is not uniform. Therefore, union fittings are used to allow free change of orientation.
