High Quality Alloy Steel Flange with SGS

Precision alloys are known for their unique physical and mechanical properties, making them essential in various high-performance applications such as precision motors, electrical appliances, measuring instruments, telecommunications equipment, and precision machinery. These alloys can be categorized into different types based on their application and special characteristics, including hard magnetic alloys, magnetically soft alloys, elastic alloys, expansion alloys, thermo-bimetal, resistance alloys, thermocouple alloys, electric conduction alloys, electric contact alloys, shape memory alloys, and superconducting alloys.

Flange Types and Specifications

• Welding Neck:
  • Preferred for high-pressure, subzero, or elevated temperature environments
  • The hub is tapered and bored to match the pipe's inside diameter, ensuring smooth flow and reducing turbulence and erosion
  • Easily radiographed and provides excellent stress distribution
• Slip-On:
  • Not typically used in high-stress applications due to low hub and weld attachment
  • Slides over the outside of the pipe
  • Inside of the flange is welded at the hub and the end of the pipe
• Lap Joint:
  • Used where bolt alignment or access for cleaning is required
  • Similar to slip-on flange when used with a lap joint stub end
  • Radius at the intersection of the flange face and bore matches the lap joint stub end
• Threaded:
  • Used where welding would be hazardous
  • Designed for low-pressure and non-cyclic applications
  • Bore is threaded to match the pipe thread
  • Tapered to seal the pipe and flanges
• Socket Welding:
  • Used for small-diameter chemical processes, hydraulic, and steam distribution lines
  • Similar to slip-on flange
  • Counterbore matches the pipe bore, allowing unrestricted flow
  • Counterbore from the hub side fits the pipe’s outer diameter - can insert the pipe in the socket with a fillet weld at the hub
• Blind:
  • Used to close ends of piping
  • Has no bore
  • Permits access to sealed lines
• Other Flanges: Orifice, Expander, Reducing, Lightweight, Studding Outlets, Long Weld Necks, Metric, Navy Drawings, Customer Drawings
