In the world of piping systems, there are many types of pipes, each designed for a specific purpose. Some of the most common are water and gas pipelines And electric welded pipes. Despite their similarities, these two types of pipes have differences in both design and application. It is important to understand these differences in order to select the appropriate material for a particular task.

ᗎ In this article, we will examine in detail what water and gas pipes and electric welded pipes are, their differences, areas of application, as well as the advantages and disadvantages of each type.

What is the difference between water and gas pipes and electric welded pipes


What are water and gas pipes?

Water and gas pipes (or pipelines for water supply and gas supply) are pipes that are designed to transport water and gas. Such pipes can be made of various materials, including steel, cast iron, plastic, and others. They are used in water supply systems, gas supply systems, and for other purposes related to the transfer of liquids and gases.

These pipes must meet strict quality standards as they often operate under high pressure and must provide reliable sealing and resistance to environmental influences.

Main characteristics of water and gas pipes:

  1. Materials: steel, polyethylene, polyurethane, cast iron, fiberglass.

  2. Strength: They must withstand high internal pressure.

  3. Corrosion resistance: Especially for pipes intended for water supply and gas supply, it is important that the material is resistant to corrosion.

  4. Low thermal conductivity: to prevent heat loss in heating systems.

  5. Tightness: The pipes must provide a reliable seal to prevent water or gas leakage.


What are electric welded pipes?

Electric welded pipes - these are pipes that are manufactured using the process electric welding. Electric welding is a method of joining pipes by heating and melting their edges with an electric arc. In this case, a strong welded joint is formed at the pipe joint. Electric-welded pipes are usually used in industry, in particular for creating pipeline systems that operate in difficult conditions.

Electric-welded pipes are often used in the oil and gas and chemical industries, as well as in the construction of various pipeline networks.

Main characteristics of electric-welded pipes:

  1. Manufacturing method: Various welding methods are used: straight-line, spiral, contact electric welding.

  2. Accuracy: Such pipes can be manufactured with high precision in diameter and wall thickness.

  3. Resistance to external influences: Electric-welded pipes have good performance characteristics, especially when it comes to steel pipes.

  4. Use in aggressive environments: Often used for systems that require high strength and resistance to chemicals and environmental influences.


The main differences between water and gas pipes and electric welded pipes

While water and gas pipes may be used in similar applications, there are several key differences between the two that are important to consider when selecting a pipe for a particular project.

1. Manufacturing method

  • Water and gas pipes can be manufactured using different methods such as welding, rolling or extrusion. Depending on the material, the manufacturing method will differ.

  • Electric welded pipes are always produced using electric welding, which allows us to create pipes with precise dimensions and guaranteed weld strength.

2. Application and areas of use

  • Water and gas pipes are designed to transport water, gas and other liquids that may be under pressure. They are often used in public utilities, at enterprises for installing water supply systems, gas supply, and in the petrochemical industry.

  • Electric welded pipes more often used in the oil and gas and chemical industries to create pipeline systems that must withstand high loads and exposure to aggressive substances.

3. Materials

  • Water and gas pipes can be made of steel, cast iron, copper, and also plastic (PVC, polyethylene, polypropylene).

  • Electric welded pipes Most often made of steel, sometimes of stainless steel or other alloys, depending on the specific operating requirements.

4. Strength and durability

  • Water and gas pipes must be as airtight and corrosion-resistant as possible, especially when it comes to drinking water pipes or gas pipelines.

  • Electric welded pipes are distinguished by high strength and the ability to withstand high mechanical loads and pressures, since the welded seam has high strength and reliability.

5. Resistance to external influences

  • Water and gas pipes must provide tightness and protection against leaks, and also be resistant to the effects of chemicals and external factors such as humidity and temperature fluctuations.

  • Electric welded pipes are particularly resistant to aggressive external influences and are highly resistant to internal loads, making them ideal for pipeline systems operating in difficult conditions.


Advantages and disadvantages of water and gas pipes

Advantages:

  • Universal application for different types of systems.

  • Durability and resistance to external influences (especially if the pipes are made of high-quality material).

  • The possibility of using various materials, including plastic, which can reduce the cost of pipes.

Flaws:

  • In some cases, they are less resistant to mechanical damage compared to electric-welded pipes.

  • Require careful preparation and installation, especially when it comes to welding.


Advantages and disadvantages of electric welded pipes

Advantages:

  • High strength of welded joints and resistance to high pressures.

  • Precision and reliability in production.

  • Good resistance to chemicals and the environment.

  • High durability and reliability when operating in difficult conditions.

Flaws:

  • More expensive to produce, especially if high quality alloys are used.

  • Production requires specialized equipment and technologies.

  • Additional corrosion protection may be required in aggressive environments.


Conclusion

Water and gas pipes and electric-welded pipes are two types of pipes that perform different functions and have their own characteristics. It is important to choose pipes depending on the operating conditions, requirements for strength, tightness and resistance to external influences. Water and gas pipes are most often used for water supply and gas supply, while electric-welded pipes are better suited for creating complex pipeline systems operating in aggressive environments.

The correct choice of pipes ensures the durability and efficiency of pipeline systems, as well as prevents possible leaks and damage, which will significantly reduce operational risks.
