What is ERW pipe used for?

ERW Pipe means Electric Resistance Welded Pipe, which are extensively used in agriculture, industry and construction activities. Considering the challenging and varied applications, ERW Welded Pipes need to conform to very high standard national and international specifications.

Electric resistance welding has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is widely used in various industrial sectors such as aviation, aerospace, energy, electronics, automobiles, and light industry. It is one of the important welding processes.

Where are ERW pipes used?

ERW pipe is versatile and can be used in a variety of applications. They are commonly used in the construction of buildings, bridges and other infrastructure projects. They are also used in the oil and gas industry to transport oil and gas from drilling sites to refineries. Additionally, ERW pipes are used in the manufacturing of cars, bicycles, and other vehicles.

Usages of ERW Pipe:

ERW Pipe is mainly used in low / medium pressure applications such as:

1. Oil and Gas Industry

Used for transporting oil, gas, and other fluids due to their strength and durability.

2. Water Supply Systems

Used in water pipelines and sewage systems because of their resistance to corrosion and high pressure.

3. Automotive Industry

Employed in the manufacture of vehicle frames, exhaust systems, and other structural components.

4. Construction

Utilized in building scaffolding, structural supports, and fencing due to their strength and ease of fabrication.

5. Agriculture

Used in irrigation systems, water wells, and other agricultural infrastructure.

6. Mechanical and General Engineering

Employed in manufacturing machinery, equipment, and general-purpose applications requiring reliable and cost-effective piping solutions.

Benefits of ERW Pipes:

Cost-Effective:
Lower production costs compared to other types of pipes, making them an economical choice for various applications.

High Efficiency:
The manufacturing process is highly efficient, leading to quick production times and consistent quality.

Precision:
The cold-forming process ensures precise dimensions and smooth surfaces, which are essential for many applications.

Strength and Durability:
ERW pipes have high tensile strength and can withstand high pressures, making them suitable for demanding applications.

Corrosion Resistance:
Often made from materials that resist corrosion, extending their lifespan and reducing maintenance costs.

Versatility:
Available in a wide range of sizes and thicknesses, making them suitable for a variety of applications.

Ease of Welding and Fabrication:
Can be easily welded and fabricated into complex structures, enhancing their usability in construction and manufacturing.

Tips: ASTM A53 is the grade of ERW high-frequency welded pipe, which is divided into Grade A and Grade B. ASTM A53 Grade B ERW is more popular than other grades. These pipes can be bare without any coating, or they can be hot dipped or galvanized and manufactured through welding or seamless manufacturing processes. In Oil and Gas, A53 grade pipes are used in the structural and non-critical applications.
