Krah Pipes OÜ is an Estonia-based manufacturer of large-diameter thermoplastic pipe systems for municipal and industrial infrastructure. The company designs and produces custom polyethylene (HDPE) and polypropylene (PP) pipes, fittings, manholes, and storage tanks using spiral-winding technology.
Its solutions cover pressure and non-pressure applications including potable water, wastewater and stormwater networks, culverts, and industrial process and cooling water. Products are engineered for corrosion resistance, smooth hydraulics, and long service life, with customizable diameters, stiffness classes, and integrated joints. Krah Pipes OÜ supports both new construction and rehabilitation methods such as relining, and provides project-specific engineering and installation support to meet relevant standards and project requirements.
Aging water tanks in Aarhus are replaced with durable, sustainable PE pipes, enhancing efficiency, reducing maintenance, and supporting long-term infrastructure reliability.
BorSafe™ HE3490-LS pipes, installed 15 years ago, still perform reliably, offering long-term durability and eliminating corrosion-related maintenance at Narva Power Plants.
