Marine Watertight Hatch Cover
Marine Watertight Hatch Cover
Introduction
The watertight hatch cover is an important outfitting device. It is used to cover the hatch and protect the cargo in the cabin from wind, waves and rain. When the ship is loading and unloading cargo, it can be easily opened and closed, and the cargo hatch cover should have sufficient strength to ensure that it will not deform under specified wind waves or other set loads and affect its use. Watertight hatch covers can be made of aluminum and steel.

Features and consequences |
||||
1. The thickness of the plate does not meet the actual requirements, and the water pressure resistance performance is bad; 2. The handle is made of carbon steel and is easy to break; 3. The hinges are made of carbon steel, easy to rust; 4. The quality of the seal (PVC) is low, easy to deform, has a pungent smell, and has a short lifespan, which may cause water in the cabin, resulting in property damage, and in severe cases, endangering the safety of the ship's navigation. |
1. The coaming and cover is strictly in accordance with the IMO standard, and has passed the hydro test of various classification societies to meet the marine standard. 2. The stainless steel handle has a sturdy structure. 3. The high-quality hatch cover sealant ensures that the deformation of the hull, hatch coaming and hatch cover can be allowed during the voyage, and the hatch cover can be sealed under any circumstances. |
