Flange Size Chart Reading Guide Understanding flange dimension tables is essential for proper flange selection, procurement, and installation. This guide explains how to read and interpret ASME flange size charts. Key Dimensions in Flange Charts 1. Nominal Pipe Size (NPS) The designated pipe size the flange connects to. Note that NPS does not equal actual […]
Understanding ASME Flange Standards When selecting flanges for piping systems, engineers often face the decision between ASME B16.5 and B16.47 standards. Understanding the key differences ensures proper specification and cost-effective design. ASME B16.5 Overview Size Range: NPS 1/2 to NPS 24 Pressure Classes: 150, 300, 600, 900, 1500, 2500 Applications: General process piping, refineries, chemical […]
Understanding Flange Pressure Ratings Flange pressure rating indicates the maximum pressure a flange can safely withstand at a specific temperature. Selecting the correct rating is critical for system safety and compliance. ASME Pressure Classes Class Max Pressure (bar) Max Pressure (psi) Typical Applications Class 150 19.6 285 Low pressure water, air, general service Class 300 […]
Threaded Flange Overview A Threaded Flange connects to pipes using internal threads, eliminating the need for welding. This makes threaded flanges ideal for applications where welding is impractical or where quick installation and disassembly are required. Design Characteristics Internal threads match pipe external threads (NPT or BSP) No welding required for installation Tapered threads create […]
Understanding Lap Joint Flanges A Lap Joint Flange consists of two components: a stub end and a backing flange. The stub end is butt-welded to the pipe, while the backing flange rotates freely around it, allowing for easy bolt hole alignment during assembly. Design Features Two-piece construction: stub end + backing flange Backing flange rotates […]
What is a Socket Weld Flange A Socket Weld Flange is designed for small-bore, high-pressure piping systems. The pipe is inserted into a recessed socket area and fillet welded to the flange hub, creating a strong, leak-proof connection. Key Features Socket bore matches pipe outer diameter for precise fit Fillet weld provides strong mechanical connection […]
Flange Standards Overview Flange design, manufacturing, and inspection must follow strict international and national standards. Understanding different standard systems is crucial for proper flange selection. ASME Standards (American) ASME B16.5: NPS 1/2 to 24 Pressure Classes: 150, 300, 600, 900, 1500, 2500 Face Types: RF, FF, RTJ, MFM EN Standards (European) EN 1092-1: Main European […]
