Class 300 Industrial Plate Flange

Product Description
Stainless Steel Plate Flange ASTM A182 F316 ANSI B16.5 Class 300 Medium Pressure Industrial Piping
Product Overview

Our Class 300 stainless steel plate flanges form the backbone of medium-pressure industrial piping, offering 2.6 times the pressure capacity of Class 150 while maintaining manageable weight and dimensions. Forged from ASTM A182 F316 stainless steel with molybdenum addition for superior pitting resistance, these flanges deliver maximum working pressures of 740 psi at ambient conditions.

Conforming to ANSI B16.5 Class 300 standards, they are the go-to specification for chemical processing, refinery utility systems, marine piping, and medium-pressure steam and gas service.

Key Features - Pressure Class Range
  • Class 300 Pressure Rating: Maximum allowable working pressure of 740 psi (51.0 bar) at 100°F, positioning this as the workhorse class for process industry applications requiring 2-3x safety margin over Class 150
  • F316 Enhanced Corrosion Resistance: Molybdenum-bearing 316 stainless steel provides critical resistance to chloride-induced pitting and crevice corrosion, extending service life in coastal, marine, and chemical environments
  • Balanced Design Philosophy: Thicker flange body and larger bolt circle compared to Class 150 provides pressure capability where needed while maintaining competitive cost and weight profiles
  • Full Size Spectrum: Available across the complete DN15-DN600 range, supporting everything from small chemical injection lines to large process headers within the Class 300 envelope
  • Dual Facing Options: RF standard with RTJ option available for high-integrity sealing in hazardous or high-temperature service
Applications
  • Chemical and petrochemical process piping
  • Refinery product transfer and utility systems
  • Marine and offshore platform seawater and firewater piping
  • Medium-pressure steam distribution and condensate return
  • Industrial gas supply and distribution networks
  • Pharmaceutical and biotechnology process utility piping
  • Pulp and paper mill chemical recovery systems
Quality Assurance

ISO 9001:2015 certified. Every Class 300 flange undergoes PMI, full dimensional verification, and visual examination. Hydrostatic shell testing, NDE (PT/UT/RT), and third-party inspection by SGS, BV, or TUV available on request.
