The main feature of these straight pipes is their perfectly smooth inner surface. The lip and bead at each end impart great stiffness, while the lengthwise laser-weld join guarantees a perfect, leak-proof seal. Its excellent finish yields top quality installations with outstanding mechanical performance.
Straight, cylindrical pipes with an outer diameter that is smaller than the inner diameter of the corresponding Multiform pipe and one totally smooth end with no lip or bead. The insertable pipes can slide inside Multiform pipes and be adjusted to the desired length. The lip at the other end is then used to connect the insertable pipe to the next section in the installation.
Male or female cylindrical collars, smooth at one end for connection by insertion and with a lip at the other end for connection using a pull-ring. Male hose connections are generally used to connect ROS ducting with flexible hoses, while female hose connections are for connections with machine outlets.
