8,000 m² Manufacturing, Controlled from Forming to Packing
With more than 10 years of manufacturing experience, Yuanzhou produces sanitary stainless steel valves and fittings in an 8,000 m² facility. The elbows shown here move through forming, end preparation, mechanical polishing, dimensional and internal-surface inspection, and protective packing. We manufacture in 304 and 316L stainless steel and support 3A, DIN, SMS, ISO, ASME BPE, RJT, IDF and BS requirements for food, dairy, beverage, pharmaceutical and biotech process lines.
Measured Quality Control
Inspection goes beyond visual checks. For each production batch, surface roughness is measured, wall thickness is checked at multiple points, and ovality is verified by comparing the maximum and minimum outside diameters. The results are checked against the drawing or order specification, while internal and external surfaces are also examined for scratches, pits, deformation and contamination before release.
