Finishing & Packing Section for ERW Tube Mill: Stacker and Automatic Bundling System

In a modern ERW tube mill, the Finishing & Packing Section plays a critical role in improving production efficiency and ensuring standardized pipe delivery. This section is mainly responsible for handling finished pipes after cutting, including stacking, counting, bundling and preparation for storage or shipment. Among all finishing equipment, the pipe stacker and automatic bundling machine are the key units.

Pipe Stacker in ERW Tube Mill Finishing Section

The pipe stacker is installed after the cut-off unit and is used to receive finished pipes from the production line. Its main function is to stack pipes in an orderly and stable manner according to preset quantity or layer requirements.

The stacker helps ensure smooth pipe flow, reduces manual handling, and minimizes surface damage during stacking. It is suitable for round, square and rectangular ERW welded tubes with different sizes and lengths. Depending on production requirements, the stacking process can be configured for single-layer, multi-layer or bundle preparation.

Main advantages of pipe stacker:

• Stable and consistent pipe stacking

• Reduced labor intensity and handling time

• Improved safety and production continuity

• Easy integration with bundling and packing equipment

Automatic Bundling Machine for ERW Welded Pipes

After stacking, pipes are transferred to the automatic bundling machine for counting and bundling. This equipment is designed to bundle finished pipes into standard packages using steel straps or other strapping materials, ensuring uniform bundle shape and secure packaging.

The automatic bundling machine improves packing efficiency and provides consistent bundle quality, which is especially important for export-oriented ERW tube mills. Bundling parameters such as pipe quantity per bundle and strapping positions can be adjusted according to customer requirements.

Key functions of automatic bundling machine:

• • Automatic pipe counting and positioning

• • Uniform and tight pipe bundling

• • Reduced manpower requirement

• • Improved packaging efficiency and consistency

Importance of Finishing & Packing Section in ERW Tube Mill

A well-designed Finishing & Packing Section helps ERW tube manufacturers reduce labor cost, improve production efficiency and meet international delivery standards. By combining pipe stackers and automatic bundling machines, tube mills can achieve smoother production flow and more reliable finished pipe packaging.

This section is widely applied in carbon steel ERW tube mills used for construction, furniture, scaffolding and general industrial applications.
