b Nominal linear masses, threaded and coupled (Column 4) are shown for information only.
c The densities of martensitic chromium steels (l80types 9Cr and 13Cr) are less than those of carbon steels; The masses shown are therefore not accurate for martensitic chromium steels; A mass correction factor of 0.989 shall be used.
d Mass gain or loss due to end finishing; See 8.5.
e Drift diameter for most common bit size; This drift diameter shall be specified in the purchase agreement and marked on the pipe; See 8.10 for drift requirements.
f Based on 758 mPa minimum yield strength or greater.
g Based on 379 mPa minimum yield strength.
Ductile iron pipes, also known as DI pipes, have become increasingly popular in water and gas applications due to their numerous advantages. These pipes, ranging from DN80 to DN2600, offer a wide range of benefits that make them a preferred choice for various industries.
One of the key advantages of DN80-DN2600 DI pipes is their durability. These pipes are made from ductile cast iron, which is known for its High strength and resistance to external forces. This makes them suitable for undergroundinstallations, where they are exposed to heavy loads and pressure. DN80-DN2600 DI pipes can withstand the weight of the soil and other external factors, ensuring long-term performance and reliability.
In addition to their durability, DN80-DN2600 DI pipes also offer excellentcorrosion resistance. The inner lining of these pipes is made from cement mortar or epoxy, which provides a protective barrier against corrosion caused by water or gas. This makes them ideal for water and gas applications, where corrosion can lead to leaks and contamination. DN80-DN2600 DI pipes can withstand the corrosive effects of water and gas, ensuring a safe and reliablesupply.
