Krah pipe systems with various stiffness classes which are designed for utility and industrial applications. It is made from High Density Polyethylene (HDPE) or PP to manufacture these pipes. The diameter of Krah profile wall pipe is from DN/ID300mm to DN/ID 4000mm. The ring stiffness is SN2, SN4, SN8, SN16 or according to customer requirements.
The extremely low weight of Krah profiled pipe allows a simpler and faster installation of the pipes, as in most cases no heavy machinery is necessary for the installation and handling of the HDPE Krah profile wall pipes. Most of the handling can be done by an excavator on-site.
Low investment costs and a service life over 100 years reduce the operating costs.
Krah profile wound pipe do not require large butt welding machines as they are joined either by rubber ring joint or electro-fusion.
The installation time is faster than other materials as the standard Krah pipes lengths are between 5.5 to 6 meters long. Fewer lifts mean unloading and loading the pipes into position saves even more time.
· Chemical and Corrosion Resistance
Krah pipes and fittings are made of the same material and jointed to one homogenous piece. Not even connections between the pieces pose a weak spot in the piping as they are joined by a rubber ring or electro-fusion water tight joint.
· Homogenous Piping
Krah pipe and fittings are made of the same material and jointed to one homogenous piece. Not even connections between the pieces pose a weak spot in the piping as they are joined by a rubber ring or electro-fusion water tight joint.
· Effective Roughness
Due to its low roughness as shown in the above graph there is almost no accumulation on the pipe bottom and Krah pipe have the ability to self purify. Low roughness has an important economic advantage as maintenance expenditure is kept to a minimum. Due to the low roughness the hydraulic properties are improved and smaller diameters are required compared to conventional pipe materials with the same flow rate. profiled pipe convey flows up to 17% greater than concrete pipes, and up to 60%better than corrugated steel pipes.
· Abrasion Resistant
Polyethylene pipes are among the most abrasion resistant pipes. This has been tested in the Darmstadt procedure and the results are shown in the diagram above and support the quality of polyethylene and polypropylene pipes.
· Resistant to Micro Organisms
Polyethylene is not nutrient media for bacteria, fungi and spores, so that the material is resistant to all forms of microbial attack as well as both sulphurous acid and sulphates.
