1. Plastic Pipe Systems

Krah’s main product focus is on large-diameter thermoplastic pipe systems for fluid transport and related infrastructure:

• Large-Diameter Pipes: Pipes manufactured from high-density polyethylene and polypropylene variants with diameters from
  DN/ID 300 mm up to DN/ID 5000 mm.

• Profiled and Solid Wall Pipes: Options range from profiled walls (offer flexibility and material efficiency) to solid walls (for pressure and demanding applications).

• Fittings & Manholes: Using the same helical extrusion process, specialized pipe fittings, junctions, manholes and accessories are produced — designed to be fully compatible with the pipes and their jointing technology.

• Long Service Life: Due to their thermoplastic materials and integrated joint systems, Krah pipe systems are engineered for a minimum 100-year service life with high resistance against corrosion, leaks and environmental stresses.

• Flexible and Durable Performance: The pipes remain flexible under load and are capable of absorbing earth movement or deformation without cracking — a major advantage over rigid materials like concrete or steel.

2. Pipe Production Machines & Equipment

Krah also designs and builds the machines needed to manufacture its pipe systems:

• Production Lines: Krah offers complete production lines such as the KR series, capable of producing pipes, fittings and manholes in the aforementioned diameter ranges with efficient, flexible operation.

• Equipment: Custom fabrication equipment such as manhole fabrication centers, welding machines and hand extruders, and house connection systems are developed to support fabrication, assembly and installation of complete pipe systems.

• Support & Service: Krah provides not only machines, but also technical service and support, training, feasibility studies, financing assistance and after-sales support to ensure successful implementation of pipeline production facilities.
