They depend on the scope of these works, which are used in the course of their machines and materials hydraulic and size of installed sanitation.

Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone.
Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains.
Logs were used for water distribution in England close to 500 years ago.
US cities began using hollowed logs in the late 1700s through the 1800s.8 Today, most plumbing supply pipe is made out of steel, copper, and plastic; most waste (also known as "soil")11 out of steel, copper, plastic, and cast iron.11
The straight sections of plumbing systems are called "pipes" or "tubes".
A pipe is typically formed via casting or welding, whereas a tube is made through extrusion.
Pipe normally has thicker walls and may be threaded or welded, while tubing is thinner-walled and requires special joining techniques such as brazing, compression fitting, crimping, or for plastics, solvent welding.
These joining techniques are discussed in more detail in the piping and plumbing fittings article.Źródło: https://en.wikipedia.org/wiki/Plumbing#Materials
