Flat Welding Neck Flange

Описание

The main feature of flat welding neck flange

• Design Features: The design feature of a flat welding neck flange is having a flat flange face and a flange neck. The flange face can be connected to other flanges, while the neck is welded to the pipeline. The neck is relatively short and does not have a tapered structure.
• Flange Connection: Flat welding neck flanges are connected to the pipeline by welding. The neck is welded to the pipeline, and the flange face is used to connect with other flanges, usually secured with flange bolts.
• Pressure Rating: Flat welding neck flanges are suitable for various pressure ratings, including common ratings such as 150LB, 300LB, 600LB, 900LB, 1500LB, and 2500LB.
• Material Selection: Flat welding neck flanges can be made from various materials, including carbon steel, stainless steel, alloy steel, etc., to meet different working environments and medium requirements.
• ASME/ANSI Standard: ASME B16.5 is the flange standard established by the American Society of Mechanical Engineers (ASME), which includes specifications and dimensions for WN flanges. Common ASME/ANSI standards include 150LB, 300LB, 600LB, 900LB, 1500LB, and 2500LB ratings.
• DIN Standard: DIN 2631-2638 is the flange standard set by the German Institute for Standardization (DIN), which includes specifications and dimensions for WN flanges. Common DIN standards include PN6, PN10, PN16, PN25, PN40, and PN64 ratings.
• EN Standard: EN 1092-1 is the flange standard established by the European Committee for Standardization (CEN), which includes specifications and dimensions for WN flanges. Common EN standards include PN6, PN10, PN16, PN25, PN40, and PN64 ratings.
• JIS Standard: JIS B2220 is the flange standard set by the Japanese Industrial Standards (JIS), which includes specifications and dimensions for WN flanges. Common JIS standards include 5K, 10K, 16K, 20K, and 40K ratings.
