What kind of connections do the pipes have? 

Pipes can be connected using different types of fittings. Some common connections are:

Local connection (coupling): This type of connection is used to connect two pipes together and can be temporary or permanent.
Valve connection: This type of connection is used to control the flow of liquids or gases in pipes.
Elbow connection: This type of connection is used to create different angles in the path of pipes.
Tee connection (T): This connection is used to connect three pipes to each other and create a radius in the flow path.
Cross connections: This connection is used to connect four pipes to each other.
Flexible connections: This type of connection is used to connect pipes that need flexibility.
Locking connections: This type of connection is used to connect pipes that need to be connected and disconnected quickly and temporarily.
Flange connections: This type of connection is used to connect larger pipes and at higher pressure.
These are just a few of the types of plumbing fittings. The choice of the type of connection depends on the specific application of piping, the type of material to be moved, the size of the pipe and the working conditions.
 
In addition to the types of pipe connections that were mentioned earlier, we will discuss some other connections in the following:

Suction fittings: These fittings are used to connect two pipes together so that they can be easily separated. These fittings are usually used for easy replacement of parts or maintenance.

Connecting fittings (connector): These fittings are used to connect two pipes of different types and sizes.

End fittings: These fittings are placed at the end of pipes to block or temporarily close the flow.

Screw connections: This type of connection is usually used in metal pipes. A screw connection is created by twisting two parts of the pipe together and can provide more flexibility.

Welded connections: In this type of connection, two pipes are welded together. This method is used to connect metal pipes using heat and creates a very strong connection.

Sealed Fittings: These fittings use sealing materials to create a leak-free connection between two pipes.

Press fittings: These fittings are made by pressing two pipes together. This method is used to connect plastic and metal pipes and creates a quick and strong connection using a press tool.

Sealing connections: This type of connection is used to prevent water or gas leakage in piping connections. These connections are usually made using rubber or Teflon seals.

Sliding fittings: This type of fittings is used to connect sliding pipes that have the ability to expand and contract. These connections are used especially when they need more flexibility.

Mechanical joints: These joints are used to connect pipes to each other by using mechanical parts such as cuts, locks and screws. These connections can be easily repaired and replaced.

Clamp fittings: This type of fittings is used to quickly and easily connect pipes to each other or to related equipment such as pumps and tanks.

Cylindrical fittings: These fittings are used in pipes that have thin walls. These connections are created by pressing a metal cylinder inside the pipes and make the two pipes connect.
