✔️ What is a tube? Introducing all types of pipes and fittings

What is a pipe?

The pipe is a hollow cylindrical part that is used to transfer the flow of fluids such as water and gas, which is installed in the facilities of residential buildings and large industrial environments. . Pipe factories use materials such as iron, plastic, steel and polymer materials in the production process. style="font-family: IRANSansFa; font-size: 1rem;">Some people think that the tube (pipe) should have a round appearance, but you should know that pipes are produced in hexagonal and even square shapes. This model of shapes is often seen in steel pipes.

✔️ Applications of pipes in different industries and construction

As you know, pipes are one of the most useful tools around us that can pass liquids and gases well. Pipes that are used in the field of liquid transportation, usually transport sanitary materials such as water from one place to another. Factories use plastic and metal raw materials to make pipes with this function. Other models are used to transport urban waste and chemical substances of industrial plants, the materials of such pipes are made of steel and polyethylene.

✔️ Related Products

Some pipes are only for transporting fluids such as gas and can pass all kinds of gaseous materials. The raw materials and materials of these types of pipes are special steel alloys, therefore they can be used to transport gaseous materials in refineries and petrochemical sectors. The design of this model of pipes is such that they can withstand the highest pressure and do not have any problems during the transfer of gas materials from one place to another. Many petrochemical companies and industrial factories are using metal tubes these days, because its compounds and raw materials are among the best resistant steel alloys.

✔️ Types of pipes and its connections

pipes are produced in various sizes and diameters, according to the materials and their applications, the name or the size of the outer diameter of the pipes is one of the criteria. And it is a very important feature that is directly related to the durability and pressure of the pipes. The same pipe factories produce this efficient device from the smallest size, i.e. 3 inches, to the largest diameter size, i.e. 65 inches. Pipes can be used in different sectors according to their diameter and specifications.

What is a polymer pipe?

Polymer pipes are pipes that, due to their properties and specifications, are currently used in various industries and facilities of all kinds of buildings. This model of tubes supports high physical and chemical properties due to raw materials used in their production stages. This has made them attract the attention of many producers and consumers.

✔️ Benefits of polymer pipes

Polymer tubes are one of the best options for metal pipes, because metal pipes rust and corrode in a very short time. In addition to being light, plastic tubes are very cheap and can be installed in the shortest possible time. Polymer Pips usually do not suffer from pressure drop, their flexibility is high and they form well, most importantly, they are electrically non-conductive and have health properties such as resistance and strength against microbiological hazards and sedimentation. Due to the fact that polymer pipes have many advantages and benefits, but they cannot withstand high temperature and pressure, the flammability of these pipes causes them to be damaged quickly. These types of pipes are very popular among industrialists and many contractors of construction facilities choose this model of pipes to move and transfer liquid materials. It should be noted that some Pips are produced using a combination of polymer and metal, and according to their type of use, they determine the physical, chemical and mechanical properties of the pipe.

✔️ Applications of polymer pipes

Polymer pipes are used in water supply and irrigation systems, horticultural and agricultural lands. They are also widely used in sectors related to urban sewage, water supply for gardens, industrial factories, animal husbandry, chemical and industrial materials, food products, etc. Currently, polymer pipes can be used instead of galvanized pipes in facilities for transferring hot and cold water.

✔️ Types of polymer pipes

The first polymer Pip produced was used as cellulose nitrate. Then different models were made such as nylon tube, polyethylene, polypropylene, polybutylene and liquid crystal polymer tubes. The types of polymer pipes are polyethylene PE pipe, PVC pipe or polyvinyl chloride PVC pipe, polypropylene pipe PP and polybutylene PB pipe. Next, we will introduce each of these pipes:

✔️ Polyethylene pipe

Polyethylene pipes are pipes that can be used to make several types of polymer pipes with high consumption. The most important of them is mesh polyethylene pipe, which is introduced with the abbreviation PEX. Many builders and designers use these pipes in underfloor heating systems, because they have high resistance to heat and high pressure, and show good resistance and strength against impact. Polyethylenes are not suitable for use in hot piping systems. They can only be used to transfer cold water.

✔️ Propylene pipe

Propylene pipes have the same use as PVC pipes, although with a slight difference, propylene has more resistance and efficiency. The lifespan of propylene pipes reaches fifty years. This pipe has a variety of connections and today it has attracted the attention of many industry and construction people. Propylenes have different types, including homopolymer, impact copolymer and organ copolymer.

✔️ PVC pipe

You must have seen PVC pipes in gray or white colors. Unlike polymers, PVC Pips are flammable and likely to break at sub-zero temperatures. Of course, note that the ignition will not only spread to other parts of the PVC pipe, but it will disappear in the same part where the ignition took place. PVC pipes should not be exposed to direct sunlight, as they will be damaged and lose their effectiveness. UV rays from the sun affect the quality of the tube. For this reason, PVC pipes are not used to transfer hot water. PVC pipes are produced and marketed in two types, UPVC and CPVC. CPVC pipes have more resistance and strength due to having more chlorine.

✔️ Plastic or Polymer Pipe Features

Many people know plastic pipes as green pipes. These types of tubes are produced from identical parts. Currently, one of the best types of pipes in urban sewage piping systems in the world are plastic pipes. Plastic tubes: They have very good strength and resistance. They withstand high pressures with the greatest strength. They have significant durability and longevity. They do not rot or rust. They are completely suitable for sanitary environments. Can be installed on the wall They are very quick and easy to install. Plastic pipes have many features and advantages, but the only drawback of these pipes is their low resistance to high heat. You can use plastic pipes in drinking water and construction sewers.

✔️ Five -layer pipe

Five-layer pipes or PEX AL PEX tubes are one of the newest generations of pipes in the plumbing industry, whose raw materials are a combination of metal and polymer. In the construction of five-layer Pips, only one aluminum layer is used, and this layer is installed between two other layers. The two layers in the five-layer pipe are connected to the polymer inner and outer parts. The metal layer designed for five-layer pipes can greatly reduce the force of sudden and strong impacts and protect the pipe from various damages. In fact, the five-layer pipe is produced by one layer of aluminum, two layers of polymer and two layers of glue. It should be noted that many defects and defects of metal and propylene tubes were solved in this type of tubes. For this reason, it is easy to use these types of pipes in building plumbing systems and facilities.

✔️ The benefits of five -layer pipes

Five-layer pipes are easy to install and have simple connections. Insulation of five-layer tubes is very suitable. Due to their resistance, they do not suffer from corrosion. They are light weight and have good flexibility. They withstand high temperature and pressure. They prevent the penetration of oxygen into the space inside Pip. None of the defects of polymer and metal pipes can be seen in five-layer pipes. They are very easy to transport. The resistance and durability of five-layer pipes is high and they have a good lifespan.

✔️ Five -layer pipe applications

They are used in the air conditioning departments of different places.
