Accumulator

The accumulator is a critical device used in ERW pipe equipment to store and buffer steel strip, ensuring that the forming and sizing machine can operate continuously at high speed without interruption caused by coil changes upstream. Through its specially designed structure and roller system, the accumulator forms the strip into a loop or wave shape, providing effective temporary storage of the strip material.

When the upstream uncoiler pauses for coil change or other operations, the steel strip stored in the accumulator can continuously supply downstream forming and welding equipment, guaranteeing seamless connection and uninterrupted production on the line. This device significantly improves overall production efficiency while effectively reducing downtime and material waste caused by coil replacement.

The accumulator accommodates various strip widths and thicknesses, featuring a flexible design that can integrate with levelers, shears, and other equipment to meet diverse production process requirements. Additionally, the accumulator system is typically equipped with sensors and automated controls to monitor and adjust strip length and tension in real time, ensuring smooth, safe, and efficient strip feeding throughout the process.
