Pipes and fittings

Polypropylene pipes and fittings are widely available in the industry. Their features include light weight, resistance to wear and welding, good thermal and electrical insulation, and chemical resistance. The presence of methyl group in the structure of polypropylene has caused its properties to change compared to polyethylene and it is a better heat insulator.

pipe

It is a piece in the shape of a hollow cylinder by which liquids and gases can be transported. The material of the pipe can be iron, plastic, steel, lead, aluminum, clay, cement, and polymer, each of which has its own use. The pipes are generally round. But some steel pipes can be produced in the form of hexagonal or square molds.

Connections

They are a type of interface between pipes and the reason for using them is to create a branch and in some cases to help reduce the size and dimensions of the pipes and to divide and change the flow path. The material of the fittings may be rubber, copper, steel, plastic, etc.

Introducing all types of pipes and fittings

Cast iron: their resistance to corrosion and useful life (100 years) has made them the type of pipes that are used in water and sewage systems. Their prices are reasonable.

Galvanized: The material of this type of pipe is white exposed iron with a diameter of 12 mm to 15 cm and a length of 6 meters. In order for these pipes to be galvanized, they must be placed in a zinc solution after production. This type of pipe is used to transport liquids and gas. Galvanized pipes are severely affected by the destructive effects of acidic and alkaline substances. These pipes are produced in two types, light and medium, which are easy to work with and have a useful life of almost 10 years, and their prices are low.

Wrought Iron: These pipes are very similar to galvanized pipes and the only difference between them and galvanized pipes is that they are also made without seams, their diameter is from 12 mm to 15 cm, and because of their lightness, it is not difficult to work with them. Wrought irons generally have a decorative aspect, but they are also used to transfer liquids and gas.

Steel: This type is one of the most widely used pipes in the industry, and after production, they are galvanized in a solution to protect them from rust. These types of pipes are light in weight and last approximately 25 to 50 years.

Copper: The most widely used pipes for water supply and air conditioning are copper pipes, but they have a high price compared to other pipes. The diameter of these pipes is small, and due to their resistance to rust, their life is long, and they are also resistant to heat and high temperatures. They show and are a good choice for transferring hot water and steam and have good plasticity.

Plastic: Plastic pipes are light in weight, which makes it very easy to work with them, and they have the ability to transport liquids and gases, and alkaline and acidic substances (because they are resistant to rust), but due to their high expansion coefficient, they have the ability They don’t transport hot materials and because of their smooth inner surface, they get less sediment and also plastic pipes are resistant to electric currents and are also flammable in combustion conditions.

Asbestos cement: They are made from a combination of asbestos, silica and cement, which are damaged by external pressure and impact, while they have good strength, their internal surface is smooth and resistant to corrosion and rust, but their sedimentation is high and can be made in diameters. They are 4 to 36 inches and can be connected to cast iron pipes.

Concrete: produced in two types, flat and simple, with diameters of 400 to 2400 mm, and in fact, concrete pipes with a diameter of less than 600 mm are called plain, and the rest, which are made of rebar, are called flat. The pure type of concrete pipes is suitable for use at low pressure, and the reinforced type is suitable for use at high pressure. Due to the weight of these pipes, it is difficult to move them, but they do not have much maintenance cost, and their average lifespan is between 35 and 50 years. They are resistant to rust, but they are defenseless against corrosive substances. In general, these pipes are suitable for use at low pressures.

Clay: Made of glazed clay that is not resistant to stress, it is used in low pressure lines, they are resistant to corrosion and have a long life.

What is the pipe and fittings industry?

The pipe and fittings industry produces and distributes all types of pipes and fittings used in the transmission and distribution of various materials, including liquids, gases, steam, oil, water, sewage, heat, cold and chemicals. This industry is one of the vital industries in the various economic infrastructures of a country.

The most important details of the pipe and fittings industry include:

1. Production of pipes: The production of all types of pipes with different materials including steel, polymers, PVC, polyethylene, reinforced concrete, etc. is done for the transmission of liquids and gases in various scales, from urban distribution lines to oil and gas transmission lines.

2. Production of fittings: production of various fittings such as couplings, elements, all types of valves, flanges, etc., which are used to connect and connect pipes and create the correct conduction transmission.

3. Distribution and sales: Pipes and fittings produced are supplied to distributors, contractors, organizations and different companies.

4. Marketing and technical consulting: This industry includes marketing activities to attract customers and provide technical consulting to customers regarding the type of pipes and fittings suitable for their needs.

5. Large projects: This industry plays an important role in large projects such as the construction of oil and gas transmission lines, construction of water and sewage facilities, building construction, chemical industries, etc.

6. Research and development: The development of new technologies in the production of pipes and fittings in order to improve their quality, resistance, productivity and increase their useful life is of particular importance.

7. Standards and regulations: The production of pipes and fittings must comply with the relevant standards and regulations of the country and industry to ensure the safety and quality of material transfer.

The pipe and fittings industry is of particular importance due to its important role in the supply and transfer of liquids and materials in the economy and infrastructure of different countries, and advanced technologies are used in it.
