Among all the characteristics of a pipeline system, pipe diameters are considered one of the most important indicators. It is this indicator that determines the choice of a particular product sample when installing the system. Also, the geometric cross-sectional size may mean parameters that we will consider below:
- Inner diameters. This indicator is the main geometric characteristic. In order to fix the pipes with each other, it is also necessary to know the internal diameters of the fittings.
- Outer pipe diameters. This value is measured in millimeters and indicated in special documents. They are divided into nominal and nominal diameters.
It is the outer diameter that can be considered an important indicator for pipes made of polyethylene, polyvinyl chloride or polypropylene. However, in many countries the internal diameters of plastic pipes are also taken into account.
In order to make the installation of the pipeline system more convenient, standard diameters are used that allow you to choose a specific product sample, based on approved standards. In these standards there is a list of those values that pipes should have when installing the system.
But during the manufacture of products, manufacturers may allow slight deviations from the nominal values. Such deviations usually do not exceed one millimeter. In order to prevent breakage after installation of the pipeline system, pipes from one manufacturer should be purchased. Only in this case, the joining of pipes with each other will be more dense and accurate.
To select the diameters of the pipes, you should use the standard method of calculation, with which the optimal section will be selected. It should be understood that the cross section provides the necessary throughput. It is from this indicator that the proper functioning of the entire system as a whole will depend.
In order to create such systems as water supply, sewerage, air conditioning and gas supply in country houses, you can use a combination of pipes with different cross-sections. Such pipes can be easily connected to each other with the help of modern fittings, which will provide the necessary reliability and tightness. The diameters of the pipes in inches in this situation should not be less than 6.3.
It is possible to use pipes with a large diameter. Typically, the geometric size of the pipes in such situations reaches 1200 millimeters. Large diameter pipes are used when installing sewer systems or for drainage systems. This is due to the fact that there is no need to maintain pressure in this case. Polypropylene pipes, which are used for the installation of gas pipeline systems, can have a diameter of up to 2400 millimeters. Products whose pipe diameters reach similar sizes are used in cases where urban communication systems are installed. But there are situations when such pipes are purchased to create private projects. In this case, selection, measurement and installation are carried out strictly on an individual basis, and it is very important to maintain constant contact between the customer and the contractor.
