Abstract

Cylindrical ducting for a pneumatic conveyor, ventilating system etc., is in two halves each formed separately and with a flanged longitudinal edge (1a, 2a). The ducting may be made of steel or aluminium. In assembly the two halves are brought together, and a longitudinal clip (3a, 3b) is applied to each joint. The seam is then closed by applying pressure to the joints. Elbows and tee pieces may be made in the same way and the ducts are joined end to end after fabrication with male and female sockets. This method allows the storing of incomplete components in a smaller space. The joints do not require soldering.
