Best 10 orifice flange Factory in China 2025

Introduction to Orifice Flange

Orifice flanges are specialized types of flanges used in pipeline systems, primarily for measuring the flow rate of fluids (liquids or gases). They are designed to hold an orifice plate in place, which creates a constriction in the pipeline. As the fluid passes through this constriction, a pressure difference is created across the orifice plate. By measuring this pressure difference, the flow rate of the fluid can be accurately determined using well - established flow equations.

Orifice flanges are crucial components in many industries, including oil and gas, chemical processing, power generation, and water treatment. They need to be manufactured with high precision to ensure accurate flow measurement and reliable operation in various harsh environments.
