Pipes are long, cylindrical tubes that are used to transport fluids (liquids or gases) or to protect electrical and optical cables and wires. They are typically made of materials such as metal, plastic, or concrete.
Fittings are used to connect pipes together, or to connect pipes to other pieces of equipment such as pumps, valves, or appliances. They can be made from a variety of materials, including metal, plastic, and rubber. Some common types of fittings include elbows, tees, couplings, adapters, and flanges.
Pipes and fittings are used in a wide range of applications, including plumbing, heating and cooling systems, industrial manufacturing, and construction. The selection of the right pipe and fitting material and size depends on the application and the type of fluid or gas being transported.
