Marine Flange

1. Construction: Marine flanges are generally composed of flanges, bolts, gaskets, etc. Flanges are a basic connection part with standard connection sizes. Bolts are used to fix flanges. Gaskets are used to ensure the sealing of flanges.
2. Features: Standardization: Marine flanges meet national or international standards, so flanges produced by different manufacturers can be used interchangeably.
High strength: The piping system on ships needs to withstand high pressure and tension, which is why marine flanges are made of strong materials.
Corrosion resistance: ships usually operate in a marine environment, marine flanges need to have good corrosion resistance to withstand the erosion of seawater and marine atmosphere.
Easily disassembled: marine flanges are bolted together and can be easily disassembled and reassembled for maintenance and replacement.

Material: Common materials used in marine flanges include cast steel, stainless steel, and bronze. These materials have good mechanical properties and corrosion resistance, which can meet the needs of various fluid delivery systems on ships.
Selection: When choosing marine flanges, it is necessary to select the appropriate material, specification and model according to the actual use scenario and demand. For example, for piping systems that need to withstand higher pressure and temperature, materials with high strength and high temperature resistance should be selected; for occasions that need to resist seawater erosion, materials with better corrosion resistance should be selected.

1. Installation: Before installing the marine flange, it is necessary to check that the flanges, bolts, gaskets and other parts are not damaged.
Connect the pipe or flange fittings to the marine flange and fix them with bolts. When tightening the bolts, they need to be tightened progressively in a diagonal sequence to ensure an even force on the flange joint.
Check that the sealing gasket is installed correctly and ensure that there are no leaks in the flange connection.
2. Maintenance: Check the marine flange connection regularly to ensure that the bolts are not loose or falling off.
If leakage is detected at the flange connection, replace the gasket or tighten the bolts when appropriate.
When removing and reinstalling the marine flange, care must be taken to protect the integrity of the flange and gasket to prevent damage.
