Diamir PVC Telescopic Pipe – a solid extension for a manhole

A PVC telescopic pipe with a diameter of 425x400mm, in orange color, designed to extend manholes with a cast iron cover. The product from the Kaczmarek brand, from the Diamir 425NW series, is an element of a system for building gravity sewage networks for various purposes – sanitary, rainwater, combined, industrial, and drainage. Thanks to the hooks for the 425 cast iron cover, installation is simple and safe.

Application and construction

This pipe is ideal for situations where the standard manhole height is insufficient and it is necessary to extend it. Made of durable PVC, it provides corrosion resistance and long-term operation. The orange color increases visibility, making it easier to locate the manhole in the field. This pipe is part of the comprehensive Diamir system, which includes various types of manholes: inspection (without and with covers) and with settling tanks. It can be used both in new installations and in the modernization of existing sewage networks.
