In medical facilities, surface hygiene and chemical resistance are paramount. Hebei Huayu Environmental Engineering Co., Ltd offers enamel‑coated steel tanks whose glass‑like interior and exterior surfaces resist microbial growth and repeated disinfection.
Manufacturing Process
Steel panels are shot‑blasted to promote enamel adhesion, then coated with a ground‑glass base layer and successive enamel frit layers. Kiln firing at 750–820 °C fuses the glass particles into a continuous, non‑porous coating. Both internal and external surfaces can be enameled, simplifying cleaning and preventing corrosion from hospital disinfectants.
Design Details
Sectional or Welded: Sectional tanks use gasketed flanges for confined‑space installation; fully welded tanks eliminate seams in less constrained areas.
Surface Quality: Enamel thickness and hardness are tested to resist scratching, chipping, and chemical attack. Surface roughness is maintained at Ra ≤ 0.8 µm to minimize bacterial harborage.
Fittings and Access: Sanitary‑grade inlet/outlet flanges, overflow lines with backflow prevention, and bolted manways with gasketed covers ensure a sealed environment.
Installation and Validation
After assembly, each tank undergoes hydrostatic testing and visual inspection for enamel integrity. Hebei Huayu provides validation protocols, including wipe‑tests and microscopy reports, to support medical‑facility quality assurance programs. Installation supervision includes training on gentle cleaning methods to preserve the enamel coating.
