PVC pipe for plumbing applications and galvanized steel pipe for instance, are measured in IPS (iron pipe size).
Worth to know
The difference between pipes and tubes is simply in the way it is sized.
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
City of hydraulicCity of hydraulic engaged in the execution of various works.
Some of them are contracted by the city authorities and owners of various public buildings, and others by owners of private flats and houses.
Therefore, the scope of hydraulic works performed in cities is very wide.
It includes both Pip drains and supervising the work performed after the flooding of the city by heavy rains and repair of hydraulic failure in flats and houses and installation of new sanitary facilities.
Such an installation can be performed by plumbers working alone or working in the company hydraulic system.
While the work is carried out after heavy rains need to rent a large company hydraulic system.
Additional services performed by plumbing work
Many plumbers addition to the usual review of the hydraulic exercises at home are also various additional services.
Sam overview of hydraulic involves assessment of the plumbing and the quality of work of individual sanitation.
In contrast, additional services may be performed by a plumber-Tile Fitter.
This type of specialist will be able to put tile in the kitchen and the bathroom and paint the walls in these rooms.
It will now also replacing defective cams and seals, and set the most appropriate water pressure and adjusts the stream of water flying to the needs of the household.
It will also be able to check the efficiency of underfloor heating and water meter.
As a result, the entire network plumbing and home heating will be able to work without complaint..
