SANSO (Hebei Sanso Machinery)

Hebei Sanso Machinery Co., Ltd

Hebei Sanso Machinery Co., Ltd designs, builds, and installs ERW welded tube mills, drawing on more than 20 years of manufacturing know-how. The company's mills cover tube diameters from 8mm up to 508mm, built to customer-specified production speed, thickness, and specification.

Alongside complete welded tube mill lines, SANSO supplies individual replacement or integration components for existing lines: uncoilers, pinch and levelling machines, automatic shearing and end welding machines, horizontal spiral accumulators, and fully automatic packing machines. The company's factory images show CNC machining centres, a floor boring mill, and gear-making equipment, indicating in-house component manufacturing rather than pure assembly.

What SANSO Makes

Entry Section of Tube Mill

• Uncoiler
• Pinch and Levelling Machine (strip flattener — handles strip over 4mm thick, 238-1915mm wide)
• Shear and End Welder
• Accumulator (horizontal spiral type)

ERW Tube Mill (by OD range)

• ERW32 (round tube mill for construction pipe)
• ERW50
• ERW76 (32-76mm OD, 0.8-4.0mm wall thickness)
• ERW89 (38-89mm OD, 1.0-4.5mm wall thickness)
• ERW114 (48-114mm OD, 1.0-4.5mm wall thickness)
• ERW165 (76-165mm OD, 2.0-6.0mm wall thickness)
• ERW219

How long has SANSO been in business?
The company states more than 20 years of manufacturing experience.

What tube sizes can SANSO's mills produce?
Individual models cover specific ranges — for example, the ERW76 covers 32-76mm OD, the ERW114 covers 48-114mm OD, and the ERW165 covers 76-165mm OD, extending up to 508mm on the largest listed models.

Can SANSO's mills make square and special-shaped tube, not just round?
Yes — each ERW mill produces round tube plus corresponding square tube and special-shaped tube.

Does SANSO sell individual components for an existing tube mill line, not just complete mills?
Yes — uncoilers, pinch and levelling machines, shear and end welders, and accumulators are available separately for replacement or integration into existing lines.

Does SANSO make sheet piling equipment?
Yes — a steel sheet pile forming line that produces both U-shaped and Z-shaped piles from one machine by changing the rolls.
