KML Cast Iron Drainage Pipe & Fitting Plumbing Products

Description

The discharge of particularly aggressive wastewater from facilities such as canteens, commercial kitchens, laboratories, medical facilities, etc. brings about special demands on drainage pipes.

Due to the properties of the materials used, KML offers all advantages attributed to a cast iron drainage system such as soundproofing properties, fire safety, temperature resistance, etc. In addition to this, KML pipes are coated on both sides, inside and outside, applying a highly resistant coating with a special procedure; this provides protection against aggressive sewage water and ensures that the pipes are suitable for underground laying.
