Stainless Steel Tube Mill
Large Diameter Industrial Precision Pipe Mill
The large diameter industrial precision pipe mill extends welded stainless steel pipe to Φ219–630 mm for industrial pipelines: food pipework, breweries, natural gas, sewage treatment, petroleum, ventilation, construction, bridges and aerospace.
The hydraulic automatic flow runs uncoiling through product storage, including internal seam flattening, enclosed seam grinding and in-line black annealing.

What is in the Large Diameter Tube Mill
The hydraulic automatic flow runs uncoiling through product storage, including internal seam flattening, enclosed seam grinding and in-line black annealing.
- 01Hydraulic automatic uncoilingHydraulic uncoiler with leveling, shear and butt welding keeps the heavy coil flow continuous.
- 02Internal seam flatteningInternal weld bead is flattened in-line, a requirement for large diameter industrial pipe.
- 03Enclosed seam grindingSealed box-type grinding station contains dust and noise on the large line.
- 04In-line black annealingBlack annealing in-line restores ductility in the weld zone before sizing.
Common questions
