Product Description
Stainless Steel Plate Flange Medium Bore DN65-DN300 ASTM A182 F304/F316 ANSI B16.5 Standard
Product Overview

Our medium bore stainless steel plate flanges covering the DN65 through DN300 range represent the core workhorse sizes for industrial process piping. Forged from ASTM A182 F304 and F316 stainless steel, these ANSI B16.5 compliant flanges cover the most commonly specified sizes in chemical plants, refineries, power stations, and water treatment facilities. The medium bore range offers the optimal balance of flow capacity and manageable weight, making it the preferred choice for process headers, pump suction and discharge connections, heat exchanger nozzles, and main utility distribution piping.

Key Features - Size Range Capability
  • DN65-DN300 Full Coverage: Eight standard sizes spanning 2.5 inch through 12 inch, covering more than 70% of industrial process piping flange applications from a single reliable source
  • Process-Optimized Dimensions: Each size in the medium bore range offers the optimal ratio of bore diameter to flange OD, providing robust connection strength without excessive weight or bolt torque requirements
  • Dual Material Availability: F304 for general process service and F316 for chloride-rich, marine, and chemical environments, both available across the entire DN65-DN300 range
  • Multi-Facing Capability: RF, FF, and RTJ facing options available across the medium bore range, enabling standardized flange procurement for projects with varying sealing requirements
  • Bulk Availability: 25,000 pieces per month production capacity with dedicated medium bore forging lines ensures consistent quality and competitive lead times for project-scale orders
Applications
  • Chemical process plant transfer lines and headers
  • Refinery product rundown and tank farm piping
  • Power plant cooling water and auxiliary system headers
  • Water and wastewater treatment process piping
  • Industrial cooling tower circulation lines
  • Pulp and paper mill stock preparation and bleaching lines
  • Mining and minerals processing slurry distribution
  • Food and beverage production main process piping
Quality Assurance
ISO 9001:2015 certified manufacturing. Every medium bore flange undergoes PMI, dimensional inspection per ANSI B16.5 tolerance tables, and visual surface examination. EN 10204 3.1 MTRs, hydrostatic testing, and third-party inspection available on request.
