Cast iron pipe was introduced to the United States in 1816. Since then, numerous other piping materials have been offered and utilized. None were able to supplant cast iron as the leading performer until Ductile iron pipe became available. The introduction of Ductile iron pipe (DI pipe) to the marketplace in 1955 remains among the most significant advancements in the history of the pressure pipe industry. It was quickly recognized as a pipe material with all the established durability of gray cast iron, yet with added strength and resiliency from its innate and lasting flexibility. It was first used for special and severe conditions of high pressure, such as where water hammer and excessive external loads might have existed.
Engineers are busy. They are faced with making critical calculations every day, especially regarding water and wastewater infrastructure. In this article, we will discuss five ways to design the thickness of Ductile iron pipe (DI pipe). Three of them are extremely quick and easy, the other two…maybe not so much
Occasionally, Installers in the water industry may experience difficulties when attempting to assemble cut lengths of large diameter pipe. This is sometimes due to ovality issues with the pipe material, especially when installing large-diameter, thin wall pipe. Inexperience with handling the occasional oval pipe can lead to a rather frustrating day. Utilization of proper materials and installation practices can resolve the issues more easily and help to ensure the pipeline will function as intended well beyond the designed expectations.
