What is an ERW pipe?
Electric resistance welded pipe (ERW pipe) is a type of steel pipe made by welding steel coils lengthwise. ERW steel pipes are made from steel strips formed into a cylindrical shape and then welded together. Welds are formed by applying pressure and electric current to the steel to melt the edges of the steel and fuse them together. ERW pipe is available in various sizes and thicknesses to meet the requirements of different applications. ERW pipe is widely used in a variety of applications due to its strength, durability and cost-effectiveness.
Advantages and disadvantages of ERW pipe:
One of the main advantages of ERW steel pipe is its cost-effectiveness. Compared to other types of pipe, such as seamless or spiral-welded pipe, ERW pipe is less expensive to manufacture and easier to produce in large quantities. This makes them a popular choice for applications requiring large amounts of pipes.
Another advantage of ERW pipe is its strength and durability. ERW pipes are made from high-quality steel and are resistant to corrosion, rust, and other forms of degradation. This makes them suitable for applications requiring high strength and durability, such as the construction, oil and gas, and automotive industries.
However, ERW pipes also have some disadvantages. One of the major disadvantages of ERW pipes is that they are not suitable for applications requiring high pressure or temperature. They also have less dimensional accuracy than seamless pipes, which can cause problems with fittings and connections.
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.
Common applications of ERW pipes in various industries:
1. Oil and gas industry
ERW pipe is widely used in the oil and gas industry to transport oil and gas from drilling sites to refineries. They are used in onshore and offshore applications and are popular for their corrosion resistance and durability. ERW pipe is also used in oil and gas pipelines, drilling casing, and refineries.
2.Construction industry
ERW pipe is commonly used in water supply and drainage systems, gas pipelines and structural support columns. ERW pipe is popular for its affordability and strength, making it ideal for construction projects.
3. Mining
ERW pipes are used in the mining industry to transport materials and equipment. Due to their strength and durability, they are used in pipes, conveyors, and structural support components. ERW pipes are also used in water supply and drainage systems for mining operations.
4. Automobile industry
ERW tubes are used in the manufacture of cars, bicycles and other vehicles. Due to their strength and durability, they are commonly used in exhaust systems, vehicle frames, and suspension components. ERW ducting is also used in vehicles’ air conditioning and heating systems.
5. Furniture industry
ERW tubes are used in the manufacture of furniture such as tables, chairs and desks. Due to their strength and durability, they are used in frames, legs, and other structural components. ERW pipe is also used in shelving and storage racks in homes and businesses.
6. Agricultural industry
ERW pipe is commonly used in agricultural irrigation systems, greenhouse construction and fencing. They are popular for their affordability and strength, making them ideal for agricultural applications.
