Pipes and Fittings

Pipes and fittings are among the most important items in the construction facilities. The following presents information related to material, size, application, selection table, and the best purchase price of all types of pipes and fittings.

Pipes and Fittings Review, Selection, and Pricing

In general, pipes are responsible for transporting or maintaining a variety of fluids, whether liquids or gases with different densities. Some people think that the pipe should have a round appearance, but you should know that there are pipes with square and hexagonal shapes, often seen in steel pipes.

According to their application, pipes are made of different materials such as steel, plastic, copper, cast iron, cement, PVC, etc.

Types of Pipes and Fittings

There are many types of pipes and fittings in terms of material:

Steel Pipes and Fittings

Steel pipes are pipes that are made of steel and are widely used in various industries, especially for connections. Pipes that are made of steel and used in building facilities are mainly divided into three groups: galvanized pipes, black pipes, and Manisman pipes.

All steel pipes can withstand high pressures and their operation is simple due to the long length of the branches (6 meters), but because they do not have an external cover, they are quickly corroded.

Galvanized Steel Pipes and Fittings

Galvanized pipes, which are one of the most important types of steel pipes, have a silver color and are mainly used for hot and cold water piping in buildings.

If the hot and cold water galvanized pipes are installed on top of the false ceiling or any other free space such as the duct of the building pipes and away from moisture with a layer of primer tape around the pipe or even black primer paint, it will have a very long life. they will be.

Naturally, to prevent the corrosion of galvanized pipes that are installed and implemented under the tiles and joinery of buildings, inside the channels of the building floor, etc., the use of primer paint with even two layers of primer tape can guarantee the length Life and durability of galvanized pipes against corrosion.

The implementation of proper thermal insulation around all the hot water pipes will significantly reduce the heat losses of the hot water pipes.

According to topic 16 of the National Building Regulations, galvanized steel piping, from a nominal diameter of 100 mm ("4") and above, the rib connection is no longer responsible and only flange connections should be used.

Black Steel Pipes and Fittings

Black steel pipes, which are traditionally mainly used in the water piping of cooling and heating systems of buildings, are also suitable if they are installed away from moisture and inside the ducts and risers with two layers of stainless coating.

Black steel pipes and fittings used in cooling and heating systems, after anti-rust paint and testing, must be completely isolated by suitable insulators to prevent heat loss.

Mannesmann Pipes and Fittings

These pipes, which are considered to be a type of seamless steel pipes, have the greatest thickness and strength of the body and the highest pressure tolerance and physical forces and are mainly used in gas piping of houses and apartments.

These pipes are used only by using Manisman connections and in the form of welding, such as welding the sides of the knee to the pipe.

Cast Iron Pipes and Fittings

These pipes are made of cast iron, and depending on their application, the types and amount of alloy, the shape and length of the pipe, and the type of connections are different, and they are often used in the sewage piping system.

Cast iron pipes are mainly produced in two types (one-sided and double-sided) and two flat ends.

Plastic Pipes and Fittings

In general, the plastic pipes used for supply water and sewage are:

• PVC Pipes (PolyVinyl Chloride)
• PE Pipes (PolyEthylene)
• ABS Pipes (Acrylonitrile Butadiene Styrene)
• PP Pipes (PolyPropylene)
• CPVC Pipes (Chlorinated PolyVinyl Chloride)
• PB Pipes (PolyButylene)
  
  

PVC pipes can be called the most used pipes in this category. Among the advantages of using PVC pipes are a much easier and faster connection of the pipe and its connections compared to other pipes, no need for painting, lightweight and the ability to install in false ceilings, smaller external diameter, and chemical resistance.

Disadvantages of PVC pipes are things like very high sensitivity to cold, loss of form and strength to heat, and low resistance to external shocks.

Dry-type PVC sewer pipes are produced in two types weak pressure in blue-gray color and strong pressure type in light gray color. Low-pressure PVC pipes are used in rainwater ventilation piping and connections for rainwater balconies and connecting pipes for sanitary facilities, but high-pressure PVC pipes are used in building sewage systems as vertical and collecting pipes, and The main sewage discharge pipe is used.

According to topic 16 of the National Building Regulations, the use of polyethylene pipes and fittings in sanitary sewage piping inside the building is allowed up to a maximum pipe diameter of 5 cm ("2"). or more, especially as a sewer riser in buildings is strictly prohibited).

Multilayer Pipes and Fittings

The five-layer pipes are a smart combination of metal and polymer and an aluminum pipe with longitudinal ultrasonic welding forms the main body of Super Pipe. This metal layer provides resistance to pressure, heat, and oxygen penetration.

Two layers of PEOC polymer and two layers of special glue make up the other components of these pipes, which has increased the life of these pipes to more than a hundred years in hard working conditions and at high pressure and temperature, even with a 2.5 times safety factor.

Pipes and Fittings Diameter Calculation

In order to calculate the diameter of hot and cold water pipes, you can use the diagram below.

You can also use the diagram below to calculate the diameter of steel pipes for heating and cooling systems.

Buy Pipes and Fittings

Pipes and fittings are produced in various sizes and diameters according to their materials and applications, the outer diameter size of pipes is one of the essential parameters and characteristics that is directly related to durability and pressure.

You must first determine the required power and pressure to easily choose and buy pipes and fittings.
