The difference between pipes and tubes is simply in the way it is sized..PVC pipe for plumbing applications and galvanized steel pipe for instance, are measured in IPS (iron pipe size).
Copper tube, CPVC, PeX and other tubing is measured nominally, which is basically an average diameter.These sizing schemes allow for universal adaptation of transitional fittings.For instance, 1/2" PeX tubing is the same size as 1/2" copper tubing.
1/2" PVC on the other hand is not the same size as 1/2" tubing, and therefore requires either a threaded male or female adapter to connect them.
When used in agricultural irrigation, the singular form "pipe" is often used as a plural.7 Pipe is available in rigid "joints", which come in various lengths depending on the material.
Tubing, in particular copper, comes in rigid hard tempered "joints" or soft tempered (annealed) rolls.PeX and CPVC tubing also comes in rigid "joints" or flexible rolls. The temper of the copper, that is whether it is a rigid "joint" or flexible roll, does not affect the sizing.7 The thicknesses of the water pipe and tube walls can vary. Pipe wall thickness is denoted by various schedules or for large bore polyethylene pipe in the UK by the Standard Dimension Ratio (SDR), defined as the ratio of the pipe diameter to its wall thickness.Pipe wall thickness increases with schedule, and is available in schedules 20, 40, 80, and higher in special cases.The schedule is largely determined by the operating pressure of the system, with higher pressures commanding greater thickness. Copper tubing is available in four wall thicknesses: type DWV (thinnest wall; only allowed as drain pipe per UPC), type 'M' (thin; typically only allowed as drain pipe by IPC code), type 'L' (thicker, standard duty for water lines and water service), and type 'K' (thickest, typically used underground between the main and the meter).
Because piping and tubing are commodities, having a greater wall thickness implies higher initial cost.Thicker walled pipe generally implies greater durability and higher pressure tolerances.Źródło: https://en.wikipedia.org/wiki/Water_pipe#Difference_between_pipes_and_tubes
Plumbing performed during house constructionLarge companies engaged in hydraulic performance of full-service plumbing.They can be rented during the construction of the house.They also participate in the process of putting up apartment buildings and schools of all sizes.It seems that the least complicated plumbing services are performed in the course of construction of the house, because they are limited to the performance of domestic water supply and sewage, and in the case of apartment blocks need to make a detailed plan of such a network adequate to the number and position of the individual apartments.However, in the case of schools you need to equip the bathroom in the right amount of sinks, where you will be able to wash their hands after using the toilet. In schools, sports can also stand up showers.
Plumbing snakes - some typesHand auger / hand spinner Hand augers are useful for clearing sink and bathtub drains.They are unsuitable for sending through flush toilets, because the wire might damage the bowl; also, flush toilets have relatively large drain pipes in which the narrow snake can be become tangled.(A 1?4-inch cable, for example, should never be used in a drain with a calibre of more than two inches.) Closet auger / toilet auger The closet auger (named after water closet) feeds a relatively short auger through a hook-shaped length of metal tubing.The hook shape makes it easier to feed the auger into the toilet.A plastic boot on the end of the auger protects the finish of the visible porcelain. Since most toilet clogs occur in the trap built into the bowl, the short cable is sufficient to break up or retrieve the greater majority of clogs.
