AC ERW mills can produce a wide range of steel pipes and tubes, making them suitable for various industries and applications.

• DC ERW mills: Different from AC ERW mills, direct current (DC) ERW mills use DC as the power source in the welding process. DC ERW mills have some advantages over AC ERW mills, such as better control of the welding process and higher welding speeds. These advantages lead to improved efficiency and product quality. DC ERW mills are commonly used in industries that require high precision and productivity.

• High-frequency (HF) ERW mills: High-frequency ERW mills use high-frequency electrical currents to weld steel pipes and tubes. The high-frequency welding process can provide faster welding speeds and better control of the heat-affected zone, resulting in high-quality welded seams. HF ERW mills are suitable for producing precision steel pipes and tubes that demand high dimensional accuracy and surface quality.

• Low-frequency (LF) ERW mills: LF ERW mills are the opposite of HF ERW mills, which use lower-frequency electrical currents for welding. They work at a lower frequency, which provides a different welding characteristic compared to HF ERW mills. LF ERW mills are cost-effective solutions for some applications that do not require high precision but have high production volumes.

• Dual-phase ERW mills: Dual-phase ERW mills can switch welding phases between AC and DC according to different production needs. This versatility allows them to optimize welding performance based on various factors such as material type, thickness, and desired output. This flexibility makes dual-phase ERW mills suitable for handling a wide range of steel grades and meeting diverse customer requirements.
