Beyond manufacturing, we act as your technical partner for food, dairy, beverage, pharmaceutical and biotech projects. We support sample validation, documentation review and technical troubleshooting, delivering reliable, compliant sanitary tubing and fittings for global buyers.

In-house Manufacturing & Production Capacity

We own integrated production lines, manufacturing sanitary tubes directly from stainless steel coils. With polishing & precision machining equipment, we supply standard sanitary tubing and fittings in bulk and accept custom orders. In-line inspection ensures stable material quality and reliable delivery.

Sanitary stainless steel tubing is continuously formed and discharged on automatic tube-making machines.

High-cleanliness sanitary tubing after precision cutting and polishing is neatly stacked for subsequent processing.

The automated fitting machining center performs high-precision turning and end-face machining on slender stainless steel tubes.

Large stainless steel coils neatly stored in the workshop serve as the main raw material for the sanitary tubing production line.
