2. What are Marine Hydraulic Watertight Doors?

Marine hydraulic watertight door are watertight doors that automatically close rooms on board ships.

They are driven by hydraulic devices, so the door leaf opens and closes reliably.

So marine hydraulic watertight door can close quickly during emergency situations.

They can also be opened and closed manually. Marine hydraulic watertight door allow for manual operation.

So you can freely select the operating method.

3. How do Hydraulic Watertight Doors Work?

The door is opened and closed by a hydraulic operating device.

Hydraulic pumps apply pressure to cylinders to open and close the door leaf.

There is also a control panel for remote control and manual operation on site.

Marine hydraulic watertight door are closed by device when the alarm sounds.

4. Frame Structure Design of Marine Hydraulic Watertight Doors

The marine hydraulic watertight door system is composed of door frame and door leaf.

AdditionSteel plate as bearing structure is the skeleton.

Apply sealing rubber strips to complete the watertight.

It should also be equipped with guide rails to guide the door.

So the hydraulic watertight door can be moved normally and not leak even if the water pressure is large.

5. Materials for Marine Hydraulic Watertight Doors 

Marine hydraulic watertight door are made of marine grade steel.

So they can bear great force without deformation.

Marine hydraulic doors also use stainless steel components.

Corrosion resistance is also a big advantage of stainless steel.

Doors also require seals to ensure that there are no leaks.

Watertight doors will guarantee long-term tightness with high-quality seals.

6. Painting Treatment and Anti-corrosion Processing

Shipping involves saltwater, so anticorrosion protection is required.

First of all, the surface of the marine hydraulic watertight door shall be sandblasted.

Then epoxy paint or anti-corrosion paint can be used for surface protection.

Furthermore, a complete coating system can also help prolong service life.

Marine hydraulic watertight door can work properly in harsh marine environments.

7. Characteristics of marine hydraulic watertight door

Marine hydraulic watertight door can bring people greater safety.

Firstly,the doors can close quickly,and isolate the water quickly.

Secondly,the hydraulic driven structure can guarantee smooth operation.

What’s more,it can equip the alarm system timely when occurring accidents.

In conclusion,the marine hydraulic watertight door have long-lasting durability.

8. Working performance advantages under marine environment

Marine hydraulic watertight door are used in a harsh vibration and pressure environment.

So they can work stably under marine environment.

In addition,the marine hydraulic watertight door have strong sealing,anti leak.

Therefore,it can improve the ship’s survivability.

Hence,the marine hydraulic watertight door have lower safety risk during use.

9. Application field of marine hydraulic watertight door

Marine hydraulic watertight door is widely used in the key area of ships.

Such as,isolating engine room quickly,eg:cut off the compartment quickly.

Else,the position of the bulkhead door need reliable watertight door to seal.

Furthermore,the marine hydraulic watertight door are also used on offshore boats.

So,it is suitable for commercial ships and industrial ships.

10. SOLAS Standard Compliance

Watertight doors need to adhere to regulations.

So marine hydraulic watertight door follow SOLAS regulations.

Additionally, classification society demand operation testing.

At ZHENXING Ship, every marine hydraulic watertight door passes.

That way customers are SOLAS regulation compliant.

For marine safety references, visit:

• International Maritime Organization (IMO)
• SOLAS Convention on Ship Safety
