Short two-layer conveying pipe for closing gaps in the conveying line. The wear-resistant inner pipe is uniformly through-hardened to 63HRC over its entire length. The outer pipe is pressure-bearing. The male-female geometry of the collar surfaces centers the pipe and seals it tightly. O-rings are used as sealing elements.
Due to the tight tolerances and after additional treatments of inner surfaces especially suitable for GRP “High performance plastics”.
