Have you ever considered how high temperatures impact your choice of piping material for a water system? It might not be something that comes to mind immediately, but it’s an important factor. Water treatment specialists pay close attention to water temperatures because they influence how the water reacts to treatment chemicals. Additionally, water and ground temperatures can significantly affect the performance of certain piping materials, particularly polyvinyl chloride (PVC).
Over the course of my 30+ year career with McWane Ductile, I’ve had the opportunity to be a part of some remarkably interesting and detailed water pipeline projects. Several of these projects have required a partnership between the community, awarding authority, contractor, water works distributor, and material manufacturer to ensure the projects were installed efficiently and correctly. However, few have matched the scale, complexity, and collaborative effort of the Saugus River crossing—part of the massive Belden Bly Bridge Replacement Project in Massachusetts. This project stands out not only for its technical challenges but also for the preparation, planning, and collaboration of key partners that brought it to a successful conclusion. In this #IronStrong Blog, you’ll hear the when, why, who, and how of this complex and intricate Ductile iron pipe (DI pipe) waterway crossing.
The landscapes and environments in which we live are constantly changing, and ensuring that resilient infrastructure is in place to support local communities is a priority for all cities. In regions where natural disasters occur and pose significant threats, such as wildfires and earthquakes, and as seen most recently in areas such as Lahaina, Hawaii, and the Palisades in the Santa Monica Mountains of Los Angeles County, California, Ductile iron pipe (DI pipe) has proven to be a durable and reliable choice for water infrastructure. This article will discuss why selecting the proper material for underground infrastructure is crucial in combating natural disasters and enabling communities to respond more effectively with a reliable source of potable water and vital fire protection.
When choosing an appropriate utility piping material for your water or wastewater project, there is so much more to consider than just the purchase price alone. This comparison between two popular piping materials – HDPE and Ductile iron pipe – demonstrates the need for more than just a cursory review or habitual choice. At McWane Ductile, we are always available to run through the matrix with you. Some installations or conditions do favor alternate materials, yet it’s hardly ever a cut-and-dried deal. Let’s take a closer look to find out why.
Odds are you may not be a certified corrosion specialist or an expert in the corrosion field for that matter. Most engineers that are responsible for specifying water projects are not. There are of course engineers who dedicate their entire careers to the subject. The good news is that McWane Ductile is committed to excellence in the corrosion field and provides professionals to assist you with making sound decisions regarding corrosion control.
Can McWane Ductile provide bonded coatings? A good question recently posed and more frequently asked due to a greater recognition of potential corrosive environments. To correctly address this question, some other questions need to be answered first.
Although McWane Ductile loves highlighting major waterworks projects, sometimes it is seeing water professionals work together to solve a utility's problem that deserves recognition. Our valued partners at Northwest Arkansas Winwater called us on Monday, April 27, 2020, with a customer in need — Benton Washington Regional Public Water Authority (BWRPWA).
Cement-mortar lining for iron pipe has been used for nearly 100 years. The first installation of gray iron pipe with a cement lining was recorded in Savannah, GA in 1922. Todays modern Ductile iron pipe still utilizes cement lining for a safe and reliable means of providing clean drinking water to millions of people every day.
On occasion, however, the cement lining may have incurred some damage in the field. The lining, although very durable, does not have the same resistance to bending stress or impact as the pipe itself. Certainly, the pipe or fitting should be checked for further structural damage, but once determined the affected area is only the cement lining, repairs can be made under the applicable provisions within the ANSI/AWWA C104/A21.4 standard CEMENT-MORTAR LINING FOR DUCTILE IRON PIPE AND FITTINGS.
The more than 75 years of ongoing research on iron pipe corrosion and the use of polyethylene encasement has led to this type of corrosion mediation becoming the accepted industry practice for protecting ductile iron pipe. So, the question many may ask is; “Since I had such success with standard polyethylene encasement, why should I now use V-Bio Polyethylene Encasement instead?” To best answer this, it’s imperative to look at what specifically V-Bio provides that is not available with standard polyethylene encasement.
Sustainability and Resiliency are today's buzzwords, especially concerning water and wastewater systems, but what does this really mean to you, the designer, manager and/or operator? Utility people today are bombarded with the answer to this question, and we believe that there is no one answer because every system is unique and experiences different priorities and different challenges.
