Base/Sealing Surface: Load Capacity ≥2× operating load

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.

Frequently Asked Questions

What is the primary function of the base/sealing surface in water tanks?

It provides structural stability while creating a perfectly flat interface for sealing elements to prevent fluid leakage.

How often should base/sealing surfaces be inspected?

During routine maintenance (typically every 6-12 months) and whenever the tank is drained for service, with particular attention to flatness and surface condition.

Can damaged sealing surfaces be repaired?

Minor imperfections can be machined or ground, but significant damage usually requires component replacement to maintain sealing integrity.
