Commonly used pipe strength is class K9 and shall comply with BS EN 598 for working pressure exceeding 6 bars. DI pipe is permitted for force mains and internal pipings of pump stations. DI pipe shall be used for gravity sewers only where it is needed to take the advantages of the high strength of ductile iron, e.g. shallow

Thickness Class Vs Pressure Class. When Ductile Iron Pipe was introduced to the market in 1965, replacing Cast or Gray iron, pipe manufacturers reached a consensus that there should be a standardized protocol for determining wall thickness.. This new standard included considerations to the inherent strength advantage of ductile iron over its cast iron predecessor.

Collapse pressure or PVC pipe crush strength is the amount of outside pressure a pipe can take before it starts collapsing inwards. This is an important measurement when burying pipe for subterranean applications. To test this type of strength, you can place weight on a pipe until it starts buckling.

DIPRA has five free webbased calculators that are useful tools for designing and specifying Ductile iron pipe. Each of the calculators is based upon a DIPRA brochure with a similar name. In some situations, both below and above ground, it is necessary to install Ductile iron pipe on supports at designated intervals along a proposed pipeline.

In abrasive wear mechanisms, austenitic ductile iron grades offer great wear resistance as well as improved strength. ADI grades of ductile iron are made by alloying the metal and heat treating. Corrosion Resistance Ductile irons corrosion resistance is superior to unalloyed steel, and even highly alloyed steels in certain environments.

Cast iron has been a recycling product in the modern sense of the term for centuries. Most plastic pipes, however, are not recycled, but burnt or disposed of at waste sites. For the manufacture of HDPE drainage pipes, manufacturers use exclusively new material, as the existing recycling plastic material is not up to the requirements.

Ductile Iron Applications. Ductile iron has greater strength and ductility than gray iron. Those properties allow it to be used effectively in a wide variety of industrial applications, including pipe, automotive components, wheels, gear boxes, pump housings, machine frames for the windpower industry, and many more.

The yield strength, or proof stress is the stress at which a material begins to exhibit significant plastic deformation. The sharp transition from elastic to plastic behaviour exhibited by annealed and normalized steels Figure 3.3 gives a simple and unambiguous definition of yield strength. For Ductile Iron the offset method is used in
