An Overview of Welded Steel Pipe: Types and Applications

2023-05-12


Welded steel pipes are manufactured through the process of welding steel plates or coils together. They are widely used in various industries such as oil and gas, construction, water supply, and transportation. In this report, we will provide an overview of the types of welded steel pipes available and their common applications.
1. Types of Welded Steel Pipes
There are four main types of welded steel pipes based on the manufacturing process:
- Electric Resistance Welded (ERW): This type of pipe is manufactured by rolling metal plates or coils and welding them together using high-frequency electric currents. ERW pipes are commonly used in water supply and heating systems, as well as for transporting gas and oil.
- Double Submerged Arc Welded (DSAW): This type of pipe is manufactured by submerging two arcs, one inside and one outside the metal plates or coils, welding them together. DSAW pipes are commonly used in the construction of buildings and bridges, as well as for transporting gas and oil.
- Spiral Submerged Arc Welded (SSAW): This type of pipe is manufactured by rolling metal plates or coils into a spiral shape and welding them together. SSAW pipes are commonly used in water supply and drainage systems, as well as for transporting gas and oil.
- Seamless: This type of pipe is manufactured by melting steel and then rolling it into a seamless tube. Seamless pipes are commonly used in high-pressure applications, such as in the oil and gas industry.
2. Applications of Welded Steel Pipes
Welded steel pipes are used in a wide range of applications due to their durability and strength. Some of the common applications include:
- Oil and Gas: Welded steel pipes are used for transporting oil and gas from drilling sites to refineries, as well as for storage and distribution.
- Construction: Welded steel pipes are used in the construction of buildings, bridges, and other structures, as well as for underground water and sewage systems.
- Water Supply: Welded steel pipes are used in water supply systems, such as for transporting water from reservoirs to treatment plants and distribution networks.
- Transportation: Welded steel pipes are used in transportation systems, such as for transporting gas and oil through pipelines and for constructing rail and road tunnels.
In conclusion, welded steel pipes are an essential part of various industries and applications due to their durability and strength. By understanding the different types of welded steel pipes available and their common applications, we can make informed decisions when selecting the appropriate type of pipe for a particular application.
