Flat weld flanges are mainly used for the connection of pipeline systems, and the pipe is inserted into the inner ring of the flange through fillet welds for welding, which is suitable for working conditions with low pressure levels and small vibration and temperature fluctuations. Its core role and use are as follows: Core role Connecting pipes: Connecting pipe ends through bolts and flange holes to form a sealing structure 12 Enhanced sealing: Secure the tube with the flange through fillet welds to prevent leakage 23 Specific uses of low-pressure and normal temperature pipelines: suitable for pipeline systems in chemical, petroleum, municipal and other fields with a pressure ≤ of 2.5MPa, such as boiler pressure vessels, water supply and drainage, etc 34 Structural Features : Flat welded flange with neck (SO): Enhance the pressure bearing capacity through the neck, apply to a wider pressure range (PN≤2.5MPa), and are often used in high-risk scenarios 35 Plate Flat Welded Flange (PL): Simple structure, low cost, but weak rigidity, disabling high-risk scenarios 35 Installation and maintenance: Easy to install, only need to correct the perpendicularity of the sealing surface to complete the welding 34. Pay attention to the quality of the weld during maintenance to avoid high temperature and high pressure or frequent temperature fluctuation environments 4. Applicable scenario restrictions Pressure level restrictions: only suitable for PN≤2.5MPa working conditions, easy to leak in high temperature, high pressure or repeated bending environment 34 Materials and structures: Most of them are made of ordinary materials such as carbon steel plates, without neck design, and cannot be directly connected with butt welded pipe fittings
