The diameter of the water pipes : all you need to know

diameter water pipes as the main parameter

water system, as we have said, the diameter plastic water pipe is one of the most important parameters of the aqueduct.On it depends the quality of the drinking water supply.This figure takes into account the construction of new communication systems or at their repair.It diameter affects bandwidth water.For example, a pipe with a larger diameter is sometimes not rational from an economic point of view, but with a small diameter pipeline may have a negative impact on all plumbing devices due to increased stress and pressure.

basic characteristics of water pipes.How not to make the wrong choice

All water pipes are distinguished not only by its size, but also the production of the material.And the first and second parameter depends on the ability to withstand a certain pipeline water pressure.

There are several materials that produce pipes for water: from various plastic polymers, metal or a combination of several kinds, and a combination of metal and plastic.

For each of the products of this type have a common characteristic - the amount of water pipes, which is the diameter.It can be divided into external and internal, as it is established on the basis of the thickness of the walls of the articles.It is up to the wall thickness depends on the level of working pressure.Steel pipes perfectly withstand high pressure due to its durability and reliability.However, heavy steel pipe, corrosion resistant, difficult to install, and is formed at its wall coating, which reduces the tube diameter and its bandwidth.Therefore, plastic analogue replaced the steel into the background.It has low weight, simple and easy assembly, relatively low cost, it is not subject to corrosion and the formation of plaque on the inside, and has plasticity.The only disadvantage of plastic pipes for water - when the temperature drops it is characteristic of linear expansion.This lack persists due to the metal-pipe, which is more reliable and much stronger.

How to properly and quickly determine the diameter of the pipes for plumbing

centimeters, millimeters, meters ... We are used to the metric system, it seems simple and is applicable to all.However, it does not match to calculate a plastic water pipe diameter.In this case, it applies special metric - inch (1 "= 25.4 mm.).The official designation of an inch looks a little different way, for example, 1 ", ¾", etc.These values ​​are used as the designation of the size of the internal water pipes.To connect the product with unknown diameters, you need to calculate it, it is quite simple.Alternatively, the Internet is easy to find ready-made conversion tables understandable for everyone.

In this metric, the values ​​look like this, for example, 16/1, with the number 16 - a measure of the outer diameter, and 1 - a wall thickness of the product.It follows that the inner diameter is 15 mm.

For household plastic water pipes, is considered optimal diameter of 1/2 "(12.7 mm.) And 3/4" (19 mm.).Also:

• pipe diameter 1/2 "(. 10 mm) and 3/8" (. 15mm) suitable for supplying water to various plumbing fixtures;
• pipe diameter of 3/4 "(20 mm.) And 1" (25 mm.) Is used as the main riser mains system.

If you find it hard to deal with the required dimensions, contact your local hardware store, calling these parameters or taking with him a sample.You will receive a free consultation, as well as pick up a suitable conduit and recommend the best for your situation fitting for you.
