A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow ? liquids and gases (fluids), slurries, powders and masses of small solids.
The term "tube" is also commonly applied to non-cylindrical sections, i.e., square or rectangular tubing.
In general, "pipe" is the more common term in most of the world, whereas "tube" is more widely used in the United States. Both "pipe" and "tube" imply a level of rigidity and permanence, whereas a hose (or hosepipe) is usually portable and flexible.
Pipe assemblies are almost always constructed with the use of fittings such as elbows, tees, and so on, while tube may be formed or bent into custom configurations.For materials that are inflexible, cannot be formed, or where construction is governed by codes or standards, tube assemblies are also constructed with the use of tube fittings.Źródło: https://en.wikipedia.org/wiki/Pipe_(fluid_conveyance)
Pipe installation is often more expensive than the material and a variety of specialized tools, techniques, and parts have been developed to assist this.Pipe is usually delivered to a customer or jobsite as either "sticks" or lengths of pipe (typically 20 feet, called single random length) or they are prefabricated with elbows, tees and valves into a prefabricated pipe spool A pipe spool is a piece of pre-assembled pipe and fittings, usually prepared in a shop so that installation on the construction site can be more efficient..
Typically, pipe smaller than 2.0 inch are not pre-fabricated.
The pipe or pipe spool is retrieved, staged, rigged, and then lifted into place.
Small pipe is typically not heavy and can be lifted into place by the installation craft laborer.
However, during a plant outage or shutdown, the small (small bore) pipe may also be pre-fabricated to expedite installation during the outage.
