Structure and Characteristics
1. Structure: Marine flanges are generally made up of flanges, bolts and seals. Flange is a standard connection size and shape of the main connection. Screws are used to fasten the flanges together. Sealing gaskets are used to make sure the flange connection is sealed.
2. Features:
● Standardization: Marine flanges comply with national or international standards to ensure interchangeability of flanges manufactured by different manufacturers.
● High Strength: Marine flanges are generally made of high strength materials because of the high pressure and tension of the marine pipeline system.
● Corrosion resistance: Ships normally operate in ocean environments. Marine flanges are required to be resistant to corrosion in sea water and ocean atmosphere.
● Easy to dismantle: Marine flanges are bolted together to allow easy disassembly and re-assembly for repair and replacement.
Working Principle
The working principle of Marine flanges is mainly through the bolt hole on the flange, and the two flanges are closely connected with bolts, so as to realize the connection and sealing of pipes, valves and other components. It uses the sealing washer between the flange, under the action of the bolt fastening force, to form a reliable seal, prevent the leakage of the medium, and ensure the normal operation of the system.
Main Structure
Marine flanges mainly consist of the following parts:
1. Flange: the main part of the connection.
2. Sealing surface: ensure the tightness of the connection.
3. Bolt hole: used to install fastening bolts.
4. Flange neck: connecting flange and pipe parts.
