Types of piping systems have been diversified to meet the need to move liquids and gases as well as to protect sensitive facilities such as electric cables.
Types of pipes can be used as tools made of metal, He found plastic and even materials such as wood, concrete and fiberglass. Pipes are used to move liquids, gases, sewage and fine particles. Generally, a piping system includes a complete connection of pipe equipment, including pipes, fittings, pumps, insulation, heat exchangers, valves. and tanks that are connected in an integrated way.
Apart from the common use of piping systems in building construction, these systems can be considered the main artery of industrial processes in factories and large industries.
Materials used in a variety of plumbing
Steel
The most used material in all types of piping systems is steel. Steel pipes in two types, seamless and welded, are used in piping systems.
Cast iron
Cast iron has a high resistance to corrosion and wear, so it is suitable for piping systems of underground water lines.< br>Copper
Due to the high cost of copper, this metal is used in precise plumbing where temperature is not an important factor.
One of the characteristics of copper pipes is that they do not leak, pollute water. they don't, they have a long life and durability.
Plastic
One of the most widely used materials for piping is plastic. Plastic pipes are mostly used in the construction industry.
Plastic pipes are cheap, flexible, light and resistant, that's why they are widely used in home plumbing systems.
These rust pipes They do not hit and are ideal for the sewage system.
Plumbing requirements
In all types of piping systems, there is a set of requirements that must be met:
The piping should be in such a way that the pipe and its connections do not impose too much weight on the system.
Support Sometimes the pipe must be adjusted in such a way as to prevent the pipes from sagging and at the same time allow the pipe to move freely to respond to natural contraction and expansion. (such as sewage piping), suitable points for steam exit should be considered.
Suitable insulation should be considered for the pipes so that they are safe from impact, corrosion and erosion.
The best method of water piping
In this method, water pipes enter the building and branches are taken from wherever possible. The traditional method was done with steel pipes, which had disadvantages such as corrosion and heavy weight. Over time, the use of plastic pipes became popular. 2. Branch piping
In this method, the branching of each unit is taken from the main riser and there is no difference between cold and hot water pipes. This method of piping is done using plastic pipes. 3. Collector piping
This piping method is considered one of the modern methods and unlike the branching method where one pipe was drawn from the main branch for each unit, in this method there is an independent valve for each unit. It is considered that it has nothing to do with other units.
This method is suitable for buildings with a high number of units and prevents water pressure drop due to high branching.
This method is Facing is not done, and for its implementation, there is no need to carve and install pipes in the depth of the wall and floor of the building.
The best method of sewage piping
This method is used in old buildings. In this method, after the installation of the sewer pipes and siphons, the piping is buried under the construction materials. This piping method is less expensive to implement. But if the piping system is defective, the cost of digging and repairs will be very high. 2. Under-ceiling sewage piping
In the under-ceiling sewage piping method, the pipes are placed under the roof of the lower floor instead of being buried under the material.
Among the advantages This method is that the pipes are not under pressure and it is much easier to access and repair it than the traditional method.
