Stub Flanges

Flanged joints in pipelines are used to create a demountable joint for future disassembly to connect valves and vessels, either where strength in tension is required, or to join to other materials. Advanced Piping Systems has a complete range of full-face flanges, accompanied by galvanised metal backing plates. A range of Stub Flanges is also available, incorporating a backing ring. These fittings are manufactured to Series 1, PN18 in accordance with Australian Standard AS/NZXS 1477. The system eliminates the traditional steel backing ring and replaces it with a sturdy structural flange plate making the joint lightweight and corrosion-resistant. The flange is designed to connect sections of pipe or tube or to join the pipe or tube to an assembly such as a pressure vessel, valve or pump. Flanges are joined by bolting, while sealing is completed with the use of gaskets and other sealing methods and fixed to the piping system by welding or threading.
