Used in most industries like oil and gas, chemical processing, shipbuilding and power generation, they provide secure, leak-free connections. Due to their square shape, it is easy to align them when installing them and therefore they are well suited for compact or restricted areas. Square flanges are also applied where repeated disassembly for maintenance is needed. Constructed from robust materials, they are highly resistant to corrosion and pressure, guaranteeing long-term use in harsh environments.
