Carbon steel flat welded flange has the following properties:
Good strength and plasticity: with high strength and good plasticity and toughness.
Cheap: Compared with other types of flanges, the price is relatively low.
Easy connection: bolt connection, easy to align when assembling.
Good sealing performance: Through the fastening of the bolt, the flange gasket is squeezed to form a seal.
However, carbon steel flat welded flanges also have some limitations:
Poor corrosion resistance: After a period of use, corrosion may occur, resulting in medium leakage.
High welding requirements: relatively high welding technology requirements, such as poor welding, easy to cause weld cracks.
Not suitable for high pressure and high temperature environment: Due to its structural characteristics, flat welded flange is not suitable for high pressure and temperature occasions.
When using carbon steel flat welded flange, it is necessary to select the appropriate material and specifications according to the specific working conditions and medium conditions, and design, manufacture and installation in strict accordance with the relevant standards and specifications to ensure its performance and safety and reliability.(YNMT)·
