Threaded plugs are primarily used to seal and protect threaded openings in a variety of industrial applications. They are commonly used in piping and hydraulic systems, as well as in mechanical equipment, to prevent fluid or gas leakage. They also help to protect against contamination, corrosion and damage to internal components.
Forged plugs are mainly used in piping systems to close or seal the ends of pipes. They are widely used in industries such as oil and gas, petrochemicals, power generation and water treatment. Forged plugs are renowned for their exceptional strength, durability, and resistance to high pressure and temperature.

What are pipe plugs?
They are fasteners designed to seal the end of a threaded pipe. They consist of cylindrical pieces of metal with external threading. When inserted into the end of a threaded pipe, they seal it. Just one pipe plug is needed to seal the end of a threaded pipe.

How do pipe plugs work?
Pipe plugs work by creating an obstruction at the end of a threaded pipe, thus sealing it. With the water or fluid supply to the pipe turned off, you can insert a pipe plug. You will need a driver for this, such as a hex socket or wrench. As you turn the appropriate driver, the pipe plug will recede into the pipe.
All pipe plugs have external threading, which enables them to seal threaded pipes. If a pipe has internal threading, you can use a pipe plug to seal its end. The external threading of the pipe plug will connect to the internal threading of the pipe.
How to Choose Pipe Plugs
If you want to seal the end of a threaded pipe, you need to choose the right size of pipe plug. It will only provide an effective seal if it fits properly. If the pipe plug is too big, it may leak. Alternatively, it may not fit at all. Measure the pipe and choose a plug to match.
Different types of pipe plug have different drive types. The drive type will determine the type of driver you need to install and remove a given pipe plug. Some pipe plugs have a hex socket drive. Others have a hex wrench drive type.
You should also consider the material when choosing pipe plugs. Since they are designed for use inside pipes, which are typically filled with water or other fluids, pipe plugs must be corrosion resistant.
