Product Description
ASME B16.5 Grade 1 Grade 2 Grade 5 Raised Face WNRF Weld Neck Flanges Class 300
ASME B16.5 standard weld neck flanges with raised face (WNRF) in Class 300 pressure rating, available in Grade 1, Grade 2, and Grade 5 materials for various industrial piping applications.
Key Features
- Weld Neck Flange (WNRF): Features a long, tapered neck welded to pipe for strong, smooth connection
- Raised Face (RF): Sealing surface raised above flange body for improved gasket sealing
- Class 300: Rated for 300 psi maximum pressure at specified temperatures
- Material Grades: Available in Grade 1 (A105 carbon steel), Grade 2 (A350 LF2 low-alloy steel), and Grade 5 (A182 F5 high-strength alloy steel)
Material Grade Specifications
Grade 1 (A105 Carbon Steel):
- Suitable for moderate temperature and pressure applications
- Temperature range: -20°F to 800°F
- Good machinability and strength for standard piping systems
Grade 2 (A350 LF2 Low-Alloy Steel):
- Higher strength than Grade 1 for demanding environments
- Temperature range: -50°F to 1000°F
- Excellent impact resistance for cryogenic applications
Grade 5 (A182 F5 Alloy Steel):
- High-strength material for extreme conditions
- Temperature range: up to 1000°F+
- Resistant to thermal stresses in power plants and refineries
Raised Face Design
- Raised height typically 1/16" to 1/4" depending on flange size
- Optimized for Class 150, 300, and 600 applications
- Provides superior pressure-tight seal with gasket
Class 300 Pressure Rating
Designed to handle 300 psi at temperatures ranging from 150°F to 1000°F depending on material grade.
Applications
- Oil & gas pipelines
- Petrochemical processing
- Power generation plants
- Chemical processing systems
- Heat exchangers and pressure vessels
