Precision-Engineered Connections
for Pressure Piping Systems
Flanges serve as critical connection components in pipelines and associated equipment, allowing for secure assembly and easy disassembly. Commonly used in the oil, gas, and petrochemical industries, flanges typically feature bolt-hole patterns for fastening and gasket profiles for pressure-tight sealing. The design and specification of each flange are determined by the pressure rating, size, and service conditions of the system in which it’s installed.
