Every flange material combination has a “temperature window”—within this temperature range, the flange, gasket, and bolts can work in coordination […]

Sealing performance assessment of in‑service flanges is an important part of piping integrity management. Unlike quality control during manufacturing, in‑service

The machining texture of a flange sealing face is a “topographic” system that determines sealing success or failure at the

A flange connection is a system composed of three core components—flange, gasket, and bolts—together with the installation process. The sealing

In the structure of a flange gasket, the inner and outer reinforcing rings are not located at the core sealing

In the design and inspection of flange seals, surface roughness of the sealing face is often treated as an indicator

Flange connections are not subjected to constant loads during service. Start‑up and shutdown operations, process fluctuations, and ambient temperature variations

“Why must the pressure that a flange can withstand at ambient temperature be discounted under high‑temperature service conditions?” This is

The reliability of a flange connection system depends not only on the flange body and gasket—the correct selection of fasteners

With the rapid development of liquefied natural gas, air separation, and low‑temperature chemical industries, the demand for flanges under low‑temperature
