ERW Steel Pipe Specifications：

Packaging & Protection
Each pipe surface is coated with a thin layer of anti-rust oil to prevent corrosion during shipping. Pipes are then wrapped with waterproof film and bundled with heavy-duty galvanized steel strapping. Threaded or beveled ends are fitted with protective caps to avoid damage. For added moisture protection, VCI paper can also be applied.

Container Loading & Space Optimization
Bundled pipes are loaded into standard shipping containers for secure transport. To maximize container utilization, we use pipe nesting – inserting smaller pipes into larger ones – which can significantly increase loading capacity and reduce shipping costs. All loading and unloading are carried out with soft slings and careful handling to maintain surface quality.

1. Oil & Gas Transmission

ERW steel pipes are extensively used in long-distance oil and gas transmission pipelines. Manufactured to API 5L standards with grades from X42 to X70, these pipes provide reliable strength, pressure resistance, and excellent weldability. Their consistent dimensional accuracy ensures smooth field welding and a secure pipeline system, making them ideal for onshore and offshore energy transportation.

2. Low-pressure Fluid Conveyance (Water, Gas, Steam)

For municipal water supply, gas distribution, and low-pressure steam systems, our ERW pipes meet standards such as ASTM A53, BS 1387, and GB/T 3091. Available in various diameters and wall thicknesses, these pipes offer a cost-effective and durable solution for transporting fluids at moderate pressures. Threaded ends and galvanized coatings can be provided for enhanced corrosion protection and easy installation.

3. Structural & Scaffolding Applications

Black ERW pipes are widely used in building construction, scaffolding systems, and structural frameworks. Compliant with standards like ASTM A500, EN 10219, and JIS G3444, these pipes provide high strength-to-weight ratios and excellent bending properties. They are commonly used for scaffolding poles, support columns, trusses, and temporary structures, offering stability and safety on construction sites.

4. High-temperature & Boiler Applications

For high-pressure and high-temperature services, ERW pipes manufactured to ASTM A106 or GB/T 5310 standards are suitable for boiler tubes, heat exchangers, and superheaters. These pipes are designed to withstand elevated temperatures and pressures while maintaining structural integrity. Strict ultrasonic and hydrostatic testing ensure reliable performance in demanding thermal environments.

5. Piling & Foundation Applications

Our ERW steel pipes are also ideal for piling and foundation projects, meeting ASTM A252 standards for pipe piles. Used in bridge piers, port facilities, and deep foundation supports, these pipes offer excellent bearing capacity and driving resistance. Thicker walls and large diameters can be customized to suit different soil conditions and load requirements, ensuring strong and stable substructures.
