The ship door is mainly the cabin fire door on the ship. The Marine door has a fireproof door frame and a fireproof door panel, one side of the fireproof door panel is hinged with one side of the fireproof door frame, and the other side has a door lock and a handle. It is characterized by an escape door above the fire door panel, and a small door panel with wind grating type at the escape door. One side of the grille type small door panel is hinged with the corresponding edge of the escape door, and the other side is provided with a latch for closing or opening the grille type small door panel. When using this type of Marine door, when encountering fire and the door panel cannot be opened, not only the cabin can be ventilated, but also the personnel can escape in time to prevent casualties.


Marine door system is made of door inner frame manufacturing, door panel manufacturing, door core panel manufacturing, door body assembly, door side panel clamping, door panel and door inner frame welding, door panel assembly process. The new fire door has the characteristics of light weight, strong, shake resistance, flame retardant, sound insulation, heat insulation, fire prevention and high strength, beneficial to assembly, and beautiful appearance.


According to the fire protection requirements of the ship's internal installation Settings and drawings, different levels of fire doors are selected. Usually the higher fire protection requirements are the selection of A-60 fire doors.


Steel fire doors are usually used more on ships. Single-sided stainless steel and double-sided stainless steel fire doors are used in places such as the kitchen, where there are more water sources. Specifically, double-sided stainless steel fire doors are used more in the kitchen, and single-sided stainless steel fire doors are used to touch the external environment on one side and touch the kitchen environment on the other.


Marine door installation method:


Assembly method: When assembling, pay attention to maintain the proper placement of the fire door, confirm the seat to try the door is not good close, the size of both sides is not suitable, after confirming the seat, you can do a good job of reinforcement, according to the specifications of the fire door is not the same, usually the way of reinforcement can be divided into three kinds:


1) Single heavy wall: the reinforcement method can be directly assembled in the top and bottom groove, then the thickness of the door frame is suitable for the width of the top and bottom groove, after assembly, the self-tapping screws are used on the top and bottom groove to strengthen the seat to ensure the fire door.


2) Double wall: usually occurs in such places as the cab, there is a composite cotton board on one side, and a steel wall on the other, and the assembly is reinforced with screws and nuts around.


3) Triple wall: usually occurs in the part of the ship from the strip steel wall, there are two layers of composite rock wool board inside and outside, and the reinforcement is in the case of composite rock wool board without assembly, the form of welding is used to fix the fire door.


Precautions during assembly:


The technical content required for the assembly of single and double walls is not much, and the welding temperature during welding should be paid attention to in the case of assembling three walls, and the temperature should be maintained to prevent the temperature from being too high and the door frame from deformation.
