A question often asked in our business is “Why did the Ductile iron pipe manufacturers all seem to get there start or have roots in Birmingham, Alabama?” If you look back at the history of Birmingham, it is easy to understand why these companies chose this area to establish their businesses. The resources, infrastructure, and manpower all came together to drive the City’s growth and make Birmingham one of the most productive industrial cities in the South.
All ductile iron pipe manufacturers use markings in a similar manner to assist customers in selecting the right material for the project. This includes verifying the material is suitable for the application intended (i.e. water or sewer) as well as adhering to the project requirements as stipulated by the owner/engineer for pipe class, lining, and exterior coating.
Because the colors used by each manufacturer may vary, we will explain how McWane Ductile applies these markings and describe their need and locations.
In this third installment about Sustainability and Resiliency for our Iron Strong Blog, we are focusing on the resiliency of pipe and pipelines as a result of natural disasters such as storms, floods, and wildfires. While earthquakes and seismic events also need to be considered, much has been written on those aspects and we will discuss them in our next installment. Resiliency means many different things to many different people, and its definition is often a matter of perspective and need. Put simply, resiliency is the ability to survive, resist, or recover from damage due to some external hazard.
Safe drinking water is essential for sustainable human life. Do you lie awake at night wondering if the water you are drinking is safe? Do you dream about the type of water lines used to transport water to your home or business?
If you are a design engineer or an official responsible for providing clean, safe water to hundreds, thousands, or even millions of residents, then you are most likely the type of person who dedicates a major portion of your time thinking about water quality.
Thankfully, there are entities and standards in place to ensure that products used in water transportation systems are of the utmost quality. In this blog, we’ll discuss the who, what, why, and how products designed to transport safe drinking water are monitored and tested during the manufacturing process at McWane Ductile to meet quality standards.
Seeing cobwebbing or small cracks in the cement lining of Ductile iron pipe (DI pipe) may raise concern for some and over the years, I’ve had some folks ask me, “Is this acceptable?” And my response is, “Yes, it is, at least to some degree.” Within this Iron Strong Blog, we will discuss Autogenous Healing (au-tog-e-nous), which is defined as the natural process of crack repair that takes place when cement linings come in contact with water.
Calcium hypochlorite is an inorganic compound added in granular or tablet form added to water to kill germs that can make people sick. When used correctly, this compound destroys germs that can cause numerous health problems. ANSI/AWWA standard C651-14 incorporates essential procedures and requirements for the disinfection of new potable water mains. In this blog, we’ll cover why, when, and how it’s used in the waterworks industry.
