Component Specifications

Definition
A door plate is a flat or shaped structural component designed to seal and provide access to manholes, inspection ports, or service doors on industrial machinery and equipment. It serves as a removable barrier that maintains containment integrity while allowing maintenance, cleaning, or inspection access to internal compartments.
Working Principle
The door plate functions as a removable closure that seals against a mating flange or frame using gaskets or seals. It is secured with fasteners (bolts, latches, or clamps) to withstand internal pressure, vacuum, or environmental conditions while maintaining a leak-tight seal. When removed, it provides safe access to internal components.
Materials
Typically constructed from carbon steel (ASTM A36), stainless steel (304/316), aluminum alloys (6061-T6), or composite materials. Material selection depends on corrosion resistance, strength requirements, temperature exposure, and regulatory compliance.
Technical Parameters
  • Seal Type Gasket or O-ring groove
  • Thickness 3-25 mm
  • Surface Finish Ra 3.2-12.5 μm
  • Pressure Rating Up to 10 bar
  • Temperature Range -40°C to 200°C
  • Flatness Tolerance ≤0.5 mm/m
Standards
ISO 9001, ASME B16.5, DIN 2501
