Product Description

A high-pressure jacketed flange is a commonly used pipeline connection component, typically employed in high-pressure and high-temperature service conditions. It consists of two flanges, a jacket, and bolts.

A jacket is a metal sleeve clamped between flanges, capable of withstanding high pressures and temperatures. Its inner diameter matches that of the pipe to ensure unobstructed flow of fluids or gases.

The high-pressure jacketed flange is joined by bolting the jacket to the flange. The number and size of the bolts are determined based on pressure and temperature requirements to ensure a secure, leak‑tight connection.

This type of flange is suitable for high-pressure piping systems in industries such as chemical processing, petroleum, and natural gas. It can withstand extremely high pressures and temperatures, ensuring the safe operation of the pipeline.

In summary, the high-pressure jacketed flange is an essential pipeline fitting used in piping systems operating under high-pressure and high-temperature conditions. It offers excellent sealing performance and structural stability, ensuring the reliable operation of the pipeline.
