Description

Product details

This image covers industrial Flanges, which are bolted connector disks used to link pipes, valves, pumps, and other process equipment to create a maintainable piping network. ## ⚙️ Technical Specifications## Sizing & Dimensional Standards * Size Range: 1/4“ NB to 76” NB. * Dimensional Standards: ANSI B16.5, DIN Standards, JIS Standards, and BS 10. * Pressure Ratings / Classes: * ANSI/ASME: 150#, 300#, 400#, 600#, 900#, 1500#, 2500#, 3000#, 6000#, and 9000#. * British Standards (BS 10): Table D, E, F, and H. * DIN/European Standards: ND 6, ND 10, ND 16, ND 25, ND 40, ND 64, and ND 100. ## Flange Facing Options * Raised Face (RF) & Flat Face (FF). * Small & Large Male-Female (M&F). * Small & Large Tongue & Groove (T&G). * Ring Joint (RTJ) (for extreme high-pressure/temperature configurations). ------------------------------ ## 📋 Material Specifications & Design Standards## 1. Stainless Steel (Corrosion Resistant & Chemical Duty) * Standards: ASTM A240 (Plate stock) and ASTM A182 (Forged grade). * Grades: F304, F304L, 304H, 316, 316L, 316H, 316Ti, 321, 309, 310, 310S, 321H, 317, 347, 347H, and 904L. ## 2. Carbon Steel (High Pressure & Structural) * Standard Grades: ASTM A105 (Premium industrial forgings), IS 2002, IS 2062, and A516 Grade 70 (Boiler/pressure vessel quality). ## 3. Alloy Steel (Chrome-Moly / Power Plant Infrastructure) * Standard: ASTM A182 * Grades: F1, F5, F9, F11, F12, F22, and F91. ------------------------------ ## 📐 Product Types & Component Categories * Weld Neck: Features a long tapered hub welded directly to the pipe bore; ideal for high-pressure, severe-stress environments. * Slip-on: Slips over the pipe end and is welded both inside and outside for easier installation alignment. * Blind / Spectacle Blind: Used to securely isolate line sections. A standard blind permanently caps a run, while a spectacle blind can be flipped to either block or allow flow. * Socket Weld: Designed for small-diameter, high-pressure pipes where a smooth internal fluid flow is preferred. * Threaded / Screwed: Attached to pipes via matched threads, completely avoiding the need for on-site structural welding. * Lap Joint / Loose: Used alongside stub ends for systems requiring quick, frequent alignment and clean-out access. * Oriface: Specialized flange set incorporating pressure monitoring ports to easily gauge fluid flow velocity. ------------------------------ Are you interested in viewing a bolt hole circle dimension table for a specific class (like 150# or 300#), or would you like to review gasket material compatibility for these facings?
