Welded Black ERW Steel Pipe Q235B Scaffolding Pipe

Structure of Q235B Welded Black ERW Steel Pipe

ERW steel pipe is resistance welded steel pipe. ERW is an abbreviation for electric arc welding. It is used to transport gases such as oil and natural gas, water, and is also used in structural steel pipes. Because its manufacturing process does not involve any welding, seamless steel pipes are considered to have higher strength and greater reliability. Historically, seamless steel pipes have had better pressure resistance than other types of steel pipes and are generally easier to obtain than welded steel pipes.

Main Characteristics of Q235B Welded Black ERW Steel Pipe

• High manufacturing precision
• High strength
• Good appearance
• Reasonable price
• Low inertial resistance
• Strong heat dissipation capacity

Manufacturing Process - High-Frequency Welding (ERW)：The steel strip is first continuously cold-formed, then high-frequency current welding is performed using the skin effect and proximity effect, achieving direct metal-to-metal bonding without filler material. After welding, internal and external burrs are removed.
