Flange Types

Class 1500 flanges come in various types, each designed for specific applications and compatibility requirements. YANHAO offers a range of flange types to meet diverse industrial needs:

Weld Neck Flanges:

  • Design: Weld neck flanges feature a long neck that extends from the flange, making them ideal for high-pressure applications.
  • Compatibility: They are compatible with pipes and fittings that have a butt-weld end, providing a robust and leak-resistant connection.
  • Use Cases: Weld neck flanges are commonly used in critical applications, such as oil and gas pipelines, chemical processing, and power generation.

Slip-On Flanges:

  • Design: Slip-on flanges have a slightly larger diameter than the pipe they connect to, and they are designed to slip over the pipe end.
  • Compatibility: They are easy to install and are suitable for applications with lower pressures and temperatures.
  • Use Cases: Slip-on flanges are often used in less demanding applications like water supply systems, fire protection, and low-pressure steam.

Blind Flanges:

  • Design: Blind flanges are solid disks used to block off the end of a piping system or vessel.
