Krah pipes are made to endure pressures and tolerances of the highest order. This makes our pipes ideal for modern applications such as water supply, sewer lines, and industrial applications where high pressure and temperature are concerns. With their high strength and flexibility, Krah pipes are incredibly reliable and can be designed to meet wide diversity of custom requirements.

Integrated with Electro-Fusion Jointing for faster project completion
Structured Wall Pipes/Profiled Wall Pipe (PR)
Despite having a very low weight, a structured wall pipe or profiled pipe can be used in applications requiring high external loads. The weight can be decreased by up to 65% when comparing a profiled pipe to a solid wall pipe with the same ring stiffness. Our pipes’ wall thicknesses can be adjusted in a range of sizes to accommodate different loads. The smooth interior and profiled exterior of the structured wall pipes are their primary characteristics. These profiles can be used in pipeline systems like sewage, drainage, storm drains, and ventilation.
Best for non-traffic and non-load bearing application
Rigid & durable
Reinforced with core tube for higher external load capacity
– Diameter sizes below 1000mm (900mm – 400mm)
– For Low Ring Stiffness: Class SN2, SN3, SN4, SN5
Covered Profile Wall Pipe (CPR)
Covered wall pipes have a smooth interior and exterior, as well as an internal profile with one or more layers. This profile is used for extremely high loads and large diameters because of its extremely long-term stiffness. It is also excellent for manholes and fitting fabrication.
Higher external pressure capacity
Rigid & durable
Reinforced with core tube for higher external load capacity
– For Medium Ring Stiffness: Class SN6, SN8, SN10, SN12, SN13
– Diameter sizes above 1000mm – 2000mm
Solid Wall Pipe
Solid wall pipes have an outer surface that is slightly uneven and an inner surface that is smooth. The pipes are made uniformly. Additionally, because these solid wall pipes are tempered, there are no frozen stresses. These pipes are suitable for use with high internal working pressure.
Suitable for high pressured application
Rigid & durable
Up to 300mm thickness
– For pressurised application
– Class: 1 BAR, 2 BAR, 3 BAR, 4 BAR
– Also used to fabricate different fittings such as bends, reducers, and manholes
– Class: 1 BAR, 2 BAR, 3 BAR, 4 BAR
– Also used to fabricate different fittings such as bends, reducers, and manholes
