Segmented T-pieces and X-pieces can be fitted in large ducts in a diameter range from 630 to 1600 mm and rated at low-, medium- or high-pressure ranges. The passage form from the main pipe to the branch port at 90o allows a smooth air flow with a minimum pressure loss. The pieces can be made with offset openings or branch ports larger than the main bore for an added value of flexible duct routing design.
