ERW steel pipes are commonly made of carbon steel or low alloy steel. This type of steel pipe is suitable for various sizes and thicknesses, ranging from small pipes for plumbing applications to larger pipes for oil and gas pipelines. What's more, ERW steel pipes usually have a smooth surface finish, making them suitable for a wide range of applications. These pipes can be bare (uncoated) or coated with galvanized coating or anti-corrosion coatings for enhanced durability.
ERW steel pipes serve many functions and are used for many purposes, such as water and wastewater transportation, oil and gas pipelines, structural and construction projects, HVAC systems, industrial and commercial plumbing, and many mechanical and engineering applications.
ERW steel pipes are crafted from high-quality steel materials, making them strong and able to withstand high-pressure conditions and heavy loads. This not only ensures superior strength and structural integrity, but also contributes to the pipes' versatility and durability.
ERW steel pipes come in a wide range of sizes - from small to large diameters - allowing for flexibility in various applications and optimum solutions for different requirements.
High weldability is one of the standout features of ERW pipes, as they are manufactured through electric resistance welding. This creates a strong and reliable weld seam that runs along the length of the pipe, upholding a consistent and durable connection between pipe segments.
ERW steel pipes come in a wide range of sizes, with outer diameters (OD) ranging from a few millimeters to several feet, and wall thicknesses measured in millimeters or inches. Typical pipe sizes are 6 meters (20 feet) and 12 meters (40 feet) in length, although they can be customized to specific lengths for project requirements. The material grade used for ERW steel pipes is important, as it determines their mechanical properties and suitability for different applications. Common materials include carbon steel (e.g., ASTM A53, API 5L) and low alloy steel, but ERW steel pipes can also be manufactured in specialty grades, such as stainless steel and duplex steels.
The oil and gas industry has a great demand for ERW steel pipes as there is extensive use of these pipes for transportation of oil, gas and other hydrocarbon fluids. These pipes are primarily used in pipelines that cover all the stages from upstream exploration and production to midstream transportation and downstream refining and distribution.
ERW steel pipes are also popularly used in water and sewage systems for a number of purposes, including municipal, industrial and agricultural purposes. All these uses highlight the reliability and efficiency of these pipes as they are able to effectively transport potable water, wastewater and for irrigation purposes.
Finally, the construction and structural engineering industries make good use of ERW steel pipes as these pipes are widely used in various structural applications. ERW pipes are commonly used in building frameworks, columns, beams and other structural components. As these pipes offer strength and durability, they are well-suited for load-bearing structures.
