About product
Marine pressure-resistant watertight doors are critical safety devices on ships, used to isolate compartments and withstand a certain level of water pressure. Their primary function is to effectively prevent seawater from entering in the event of hull damage or compartment flooding, ensuring the vessel’s overall stability and navigational safety.
- Pressure Rating: Depending on the location and design requirements of the bulkhead, doors are classified as light-duty (0.1 MPa) and heavy-duty (≥0.3 MPa), with some special models capable of withstanding higher water pressures.
- Testing and Certification: All watertight doors undergo rigorous hydrostatic testing and are certified by classification societies such as CCS, ABS, DNV, or LR, ensuring watertight integrity and reliability.
- Safety and Reliability: The door structure and sealing system are optimized to allow rapid opening and closing in emergencies while maintaining long-term stability and safety.
