Component Specifications

Definition
The base/sealing surface is a precisely machined structural component that forms the foundation of industrial water tanks. It serves dual functions: providing stable mechanical support for the tank assembly and creating a perfectly flat, smooth interface for gaskets or sealants to prevent fluid leakage. This component must maintain dimensional stability under varying loads and thermal conditions while ensuring consistent sealing performance throughout operational cycles.
Working Principle
The base/sealing surface operates on mechanical sealing principles where two precisely machined surfaces create a barrier against fluid passage. When compressed with gaskets or sealants, microscopic imperfections are filled, creating a hermetic seal. The component distributes structural loads evenly while maintaining flatness within specified tolerances to prevent stress concentrations that could compromise the seal integrity.
Materials
Stainless steel (AISI 304/316), carbon steel with corrosion-resistant coating, or engineered polymers (PP, PVC) depending on application requirements. Surface finish: Ra ≤ 1.6 μm for metal surfaces, specific roughness requirements for polymer surfaces.
Technical Parameters
  • Load Capacity ≥2× operating load
  • Surface Roughness Ra 0.8-1.6 μm
  • Flatness Tolerance ≤0.1 mm/m
  • Corrosion Resistance Per ASTM B117 salt spray test
  • Thermal Expansion Coefficient Matched to tank material
Standards
ISO 9001, DIN 28018, ASME BPVC Section VIII, EN 13445
