Are you looking for the best steel pipes for your project? You have recently heard about ERW steel pipes that can help you meet high and low-pressure requirements. These rounded steel pipes are mostly used for oil, natural gas, and other vapour-liquid transportation. Therefore, other engineering applications can also use these round structural steel pipes for fencing, scaffolding, line pipes, etc.
No doubt, it has become more popular in the transportation pipe & construction tube industry. Learn how ERW steel pipes are manufactured and the advantages of using them.
What is ERW Steel Pipe?
Electrical Resistance Welded ( ERW) Structural Steel Pipe is made of carbon steel coil, which has low strength and hardness properties. Also, the durability is increased by the weld seam that runs parallel to the pipe.
At APL Apollo, ERW structural steel pipes and tubes are manufactured by transforming cold flat steel strips into rounded tubes and passing them through a set of forming rollers to produce a longitudinal seam. The two edges of a seam are heated with a high-frequency resistance and pressed together to form a bond.
No metal filling will be needed for the longitudinal ERW as impurities in the heat zone are extruded during the welding process. Thus, this process makes electro-welded steel pipe more durable.
Five Key Advantages of Apollo ERW Steel Pipes
Steel ERW pipes are formed from hot rolled steel plates through repeated shaping, bending, welding, heat treatment, sizing, straightening, cutting, and heat treatment.
1) High dimensional accuracy: Electrical-resistance welded pipes are rounded pipes with a small diameter and thin width of the wall. It is made with high-frequency induction welding to achieve accurate dimensions.
2) Good mechanical properties: Manufacturers can control the strip rolling of ERW steel pipe effortlessly because of its innovative welding technology. ERW Steel pipes can be rolled effortlessly because of its innovative welding technology, which enables manufacturers to control the strip rolling process. The welded part is also passed through online heat treatment technology to improve its performance. Hence, it helps to reduce material wastage.
3) Higher Elongation: Straight seam welded steel pipe can elongate 8% -10% higher than traditional seamless steel pipes. Besides, an electric-welded steel pipe consumes less carbon than other steel tubes and pipes.
4)Uniform wall thickness: ERW steel pipe has high concentricity and uniform thickness after heat treatment. Its microstructure makes the steel pipe more durable and resistant to collapse. Also, it offers higher elongation compared to other seamless steel pipes.
5) Longitudinal resistance: Welded steel tubes undergo rigorous heat treatment to ensure their durability. It will not collapse during transit and can provide high resistance to all external forces. This is why it can be used to manufacture small diameter thin-walled pipes, commonly used in the city to transport gas and crude oil.
Summing Up! Only the best ERW steel pipes will offer you all the advantages mentioned in the list. APL Apollo manufactures structural steel pipes and tubes with higher resistance to heat and temperature. They are easy to install and have a long service life. Click here to know more.

The Benefits and Drawbacks of ERW Pipes
Electric Resistance Welded (ERW) pipes are commonly used in a wide range of industries, including oil and gas, construction, and water supply. ERW pipes are created by the process of electric resistance welding, which involves passing an electric current through a metal strip to create a weld between two pieces of metal. The use of ERW pipes has increased in recent years due to their many benefits, including cost-effectiveness, ease of use, and availability. However, like any other product, ERW pipes also have their drawbacks. In this essay, we will explore the benefits and drawbacks of ERW pipes and examine their overall effectiveness as a product.
Benefits of ERW Pipes:
1'Cost-effectiveness:
One of the most significant benefits of ERW pipes is their cost-effectiveness. ERW pipes are less expensive than seamless pipes, which are produced through a more complicated process. ERW pipes are also more cost-effective than welded pipes made using other methods. The lower production cost of ERW pipes makes them an attractive option for industries looking to reduce costs.
2'Ease of use:
ERW pipes are easy to use, making them a popular choice for industries that require quick and efficient installation. ERW pipes can be easily cut and welded together, which reduces the need for specialized tools and equipment. ERW pipes also come in a variety of lengths and diameters, making them adaptable to a wide range of applications.
3'Availability:
ERW pipes are readily available, making them an attractive option for industries that require a constant supply of pipes. ERW pipes are produced in large quantities, making them widely available from a range of manufacturers. The availability of ERW pipes reduces the risk of production delays and ensures a steady supply of pipes for industries that rely on them.
4'Strength and Durability:
ERW pipes are strong and durable, making them suitable for use in a wide range of applications. ERW pipes are made from high-quality steel and are designed to withstand the rigors of use in harsh environments. ERW pipes are also resistant to corrosion, making them a reliable option for use in industries that require corrosion-resistant pipes.
5'Versatility:
ERW pipes are versatile, making them suitable for use in a wide range of industries. ERW pipes are used in the construction industry for the construction of buildings and bridges, in the oil and gas industry for the transportation of oil and gas, and in the water supply industry for the transportation of water.
Drawbacks of ERW Pipes:
1'Welding Defects:
One of the drawbacks of ERW pipes is the potential for welding defects. The welding process used to create ERW pipes can create defects such as porosity, lack of fusion, and cracks. These defects can reduce the strength and durability of the pipes and can lead to leaks and failures.
2'Quality Control Issues:
Another drawback of ERW pipes is the potential for quality control issues. ERW pipes are produced in large quantities, and it can be challenging to ensure that each pipe meets the required quality standards. Quality control issues can lead to defects in the pipes, reducing their strength and durability and increasing the risk of failure.
3'Limited Size Range:
ERW pipes have a limited size range, which can be a drawback in some industries. ERW pipes are typically available in smaller diameters than seamless pipes, which can limit their use in industries that require larger pipes.
4'Susceptible to Corrosion:
Although ERW pipes are resistant to corrosion, they are still susceptible to corrosion in certain environments. ERW pipes that are exposed to corrosive materials or environments may corrode over time, reducing their strength and durability and increasing the risk of failure.
5'Reduced Load Capacity:
ERW pipes have a reduced load capacity compared to seamless pipes. The welding process used in ERW pipes creates a welded seam along the length of the pipe, which can be a weak point. This welded seam reduces the load-carrying capacity of the pipe compared to seamless pipes, which have a continuous structure without any welded seams. In applications where high pressure or heavy loads are involved, seamless pipes may be a more suitable choice.
Conclusion:
ERW pipes offer several benefits, including cost-effectiveness, ease of use, availability, strength, durability, and versatility. These advantages make ERW pipes a popular choice in various industries. However, it is essential to consider the drawbacks associated with ERW pipes, such as welding defects, quality control issues, limited size range, susceptibility to corrosion, and reduced load capacity.
To mitigate these drawbacks, proper quality control measures should be implemented during the manufacturing process of ERW pipes. Regular inspections and testing can help identify and address welding defects and ensure that the pipes meet the required quality standards. Additionally, proper maintenance and protection against corrosion can extend the lifespan of ERW pipes in corrosive environments.
In conclusion, while ERW pipes have their drawbacks, their benefits and overall effectiveness make them a viable option for many applications. It is crucial to consider the specific requirements and conditions of each project when selecting the type of pipe to use. Proper installation, maintenance, and quality control practices can maximize the benefits of ERW pipes and minimize the potential drawbacks, leading to successful and efficient pipe systems in various industries.
