Brief introduction

The oiltight hatch cover is mainly used for the entrance and exit of the cargo oil tank of the oil tanker for personnel inspection and clearance, and has oil and gas tightness. Oil resistant materials are used as dense fillers. The transmission parts are generally made of copper alloy to avoid sparks caused by collisions during opening and closing. There are two types of oblong shape and circular shape, and the common type is horizontal rotation. The diameter of the through hole of the circular shape hatch cover is generally 600mm ~ 1200mm, and there is an observation hole with a diameter of not less than 150mm on the hatch cover plate, and the hole is equipped with an oil-tight cover closing device and a fireproof copper wire net.

Design feature

• Marine rotating oiltight hatch cover:

Usually designed round or square to suit the shape of the oil hatch.

The structure is rotatable and is usually equipped with a powerful sealing system, such as high-quality rubber seals, to ensure that the oil does not leak.

High-strength metals, such as stainless steel or aluminum alloy, are often selected to meet the challenges of the Marine environment.

• Ordinary marine small hatch cover:

A variety of structures can be fixed, pull up and down or sidesslip, etc., to adapt to the needs of different ship areas.

Usually does not have particularly strict sealing requirements, can be used to cover hatches, cargo holds, decks and other areas.

A wide range of materials can be metal, plastic, composite materials, etc., according to actual needs and budget choices.

functional comparison

• Marine rotating oiltight hatch cover:

It is mainly used to cover the oil hatch of the ship to ensure the safety of oil storage and prevent environmental pollution and ship accidents caused by leakage.

With excellent sealing performance and structural strength, it is suitable for scenarios requiring strict control of oil management and leakage prevention.

• Ordinary marine small hatch cover:

It is more widely used and can be used to cover various areas such as hatches, cargo holds, decks, etc., mainly to protect cargo and cabin facilities from the external environment.

The function is mainly in the convenience of cargo storage and ship operation, which usually does not require particularly strict sealing requirements.

Application scenario

• Marine rotating oiltight hatch cover:

Suitable for ships requiring strict control of oil management and leakage prevention, such as oil tankers, oil tankers, etc.

It is widely used in situations that require compliance with strict regulatory requirements, protection of the Marine environment and ensuring the safety of ships.

• Ordinary marine small hatch cover:

It is suitable for general cargo ships, passenger ships and multi-purpose ships, and is used for covering various hatches, cargo holds and decks.

It is mainly used for the convenience of cargo storage and ship operation, and has a wide range of applications.
