Construction pipes are a basic element in every building and are used to transport different fluids such as water, gas and sewage. These pipes are produced in different types, each of which has specific characteristics, advantages and applications.
Types of building pipes
Metal pipe
Galvanized pipes: these pipes are covered with zinc coating and have high resistance to corrosion. They are used in water supply and sewage systems.
Copper pipes: due to their high thermal conductivity and resistance to corrosion, they are used in heating and cooling systems and transfer of industrial fluids.
Steel pipes: very high resistance to heat, They have pressure and corrosion and are used in heavy industries and piping systems with harsh conditions.
Plastic pipes
PVC pipes: they are light, cheap and resistant to corrosion. They are used in water supply, sewage and ventilation systems.
Polyethylene pipes: they are flexible, resistant to impact and freezing. They are used in irrigation and gas supply systems. PEX pipes: flexible, resistant to heat and pressure. They are used in floor and radiator heating systems.
cast iron pipes
have a very high resistance to pressure and impact. They are used in main sewage networks and high diameter water transmission lines.
Composite pipes
are a combination of two or more materials and are usually light, resistant and thermally insulated. They are used in industrial piping systems and tall buildings.
Pipes and fittings are very important and vital in the construction industry. Pipes are the vital arteries of all buildings, which are responsible for transporting water, gas, and even the electricity supply network. The importance of the presence of pipes in today's buildings is so high that it is basically impossible to build a building without using pipes.
Steel pipes
Steel pipes are among the pipes that have many applications in the construction industry. The types of steel pipes are:
Black Pipe
Black steel pipes are actually the simplest type of steel pipe, which are often circular in cross-section and have no protective coating. Black pipes are divided into two groups, seamed and seamless.
Sealed type of black steel pipes are used for transferring liquids, making metal artifacts and structures, and producing profiles. While its seamless type has almost similar applications, it is different in terms of construction. In this way, different welding methods of metals are not used in its production process. Also, in terms of the raw material, they have differences with the seamed type of black pipe. The major part of the country's needs in terms of the production of this pipe is provided from within the country.
Galvanized pipe
Galvanizing is actually the process of coating metal sheets. Galvanized metal sheets are actually plates that are hot or cold galvanized in their production process, or in simpler words, special coating.
Of these galvanized construction rolls, they are actually the black seamed steel pipes that are galvanized after being produced. The purpose of this coating is to protect the pipe against environmental conditions and the resulting decay and corrosion. Also, this coating protects the inner and outer walls of the pipe against moisture and chemicals.
Most of the galvanized construction pipes are available in the market as six-meter branches, and instead of welding, rib joints are used for them. These pipes are also known as white pipes in the market and they can be made of iron instead of steel. But its steel material has better quality and resistance.
Price of steel pipes
The price of steel pipes is determined according to the price of its raw material, i.e. steel. Since the price of metals, including steel, has always fluctuated a lot, especially now, to get its price, you need to know the daily price of steel pipe.
You can consult the experts of Kashishi company to get the daily price and buy steel pipe and get information about the latest products of this company along with the latest prices. Kashishi Trading is one of the most reliable companies in the field of production and distribution of all kinds of installation equipment, including all types of pipes.
Plastic pipe
If we ignore the use of plastic pipes for electrical installations and building wiring, the most important and most used plastic pipes in the construction industry is for water supply systems and cold and hot water transfer. The resistance threshold of plastic pipes is high and they have easy connections. Also, they have good resistance against moisture and can be produced in different types. These features have made plastic pipes to be used and popular in various industries, including the construction industry. The types of plastic pipes used in the construction industry are:
PVC plastic tube or polyca tube
The word Plica is actually something like Tide. Just as Tide is a very well-known brand name of a detergent manufacturer, and has become so common that people recognize the product name by its brand name, Polica is actually a brand name applied by top manufacturers of PVC pipes. You often see and know these pipes in gray color.
Polyca or PVC pipes have a very good resistance and will not break soon. This is what has made these pipes popular in the construction industry. Especially in the water and sewage facilities of the building.
One of the most common applications of PVC pipe or polica pipe in various industries is the use in the connections of sewage systems, industry and urban development, urban water and electricity supply systems, telecommunication lines and building air conditioning systems.
But besides the many advantages, the polica pipes are not without flaws. Among the defects of PVC pipes, we can mention things such as fragility against extreme cold, reduced resistance against extreme heat, and low resistance against external physical damage.
PE plastic tube or polyethylene pipe
PE pipes or polyethylene pipes are another common type of plastic pipes, which themselves have different types. The types of these pipes are divided due to their different features and advantages. The first type of polyethylene pipes have low density and high flexibility, but they show little heat resistance. On the other hand, the second type of these pipes have more thermal resistance, but their density and flexibility are less. And the third type, which is considered the best type of polyethylene pipe, in addition to its density and weight, it also has more resistance and expandability than the previous two types. Their weight has made them widely used in the construction industry. In addition to being used for water supply systems, these pipes are also used in making electrical hose pipes.
Pp plastic tube or polypropylene pipe
The most important feature of polypropylene plastic pipes is their high resistance to non-oxygen acids and heat.
In addition to the above three, there are other plastic pipes in the market. including cpvc, ABS and PB pipe. Each of them have their own special applications according to their characteristics, but they are never used as much as the three main models of plastic pipes.
Among all types of plastic pipes, the PVC and PE type, i.e., the poly pipe and the polyethylene pipe, are more common than others. All kinds of pipes are used in water and sewage systems.
Price of plastic pipe
Plastic pipes are generally cheaper than metal pipes. It is for this reason that in various industries, as long as there is no urgent need for metal and steel pipes, it is preferable to use plastic pipes. These types of pipes with different resistances can replace metal pipes in many cases.
Cast iron pipes
Cast iron pipes are mostly used in sewage systems. These pipes are made of cast iron and their connections can be different based on their material. Cast iron pipes are generally made in two types, with bushings and without bushings. The cast iron pipe with bushings is also called flat and the pipe without bushings is called flat.
Among these two main models of cast iron pipes, straight pipes have more pressure resistance, and are more useful due to their lower weight and thickness. These types of pipes are also more resistant to temperature changes due to their elasticity. Among the most important advantages of cast iron pipes are the resistance to pressure from inside and outside the pipe, the convenience of using an air compressor to open the pipe, and the cheaper price. He pointed to similar iron models.
But besides these advantages, it is better to point out the disadvantages of this cast iron pipe. Things such as slow installation speed, high rustability and high weight are the most important disadvantages of cast iron pipes.
