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.
"Do it safely or not at all." That is the McWane Way. At McWane Ductile, we are committed to providing a safe work environment for our employees. In this #IronStrong Blog, we will discuss the OHSA Voluntary Protection Program (VPP), what it is, and why it is important to employers, employees, and you.
November 8 is National STEM/STEAM Day, highlighting the importance of Science, Technology, Engineering, Arts, and Mathematics in children’s education. The manufacturing of Ductile iron pipe (DI pipe) and constructing pipelines for water and wastewater infrastructure are complex processes that rely heavily on STEM principles. In this #IronStrong Blog, we will explore the intricate connections between these fields and their significance in ensuring safe and efficient water and wastewater management now and in the future.
What do balancing a checkbook and restraining Ductile iron pipe (DI pipe) have in common? They are both important skill sets that lead to peace of mind. A typical waterline experiences thrust forces produced by fittings, closed valves, or dead ends. These forces must be "balanced out” or canceled to maintain the pipeline’s longitudinal integrity across the joints. Similar to managing a checkbook, the weight of the pipe, the water contained in it, and the backfill above it, along with the pipeline's friction with surrounding soils, help counteract a portion of the "thrust force" bill. The remaining force must be zeroed out using a calculated length of restrained joint pipe and fittings, following the ASTM/AWWA calculation protocols.
In this #IronStrong Blog, we will explain thrust forces, how they are created in a water line, why they are important, the information needed to calculate them, and how to easily calculate them using the McWane Pocket Engineer™. Once you have those calculations, we will show you what pipe joints to use and in what quantities to make your pipeline restraint secure for generations.
