This Blog Reflects Significant Updates for Envision Manual V3. As we know, America's infrastructure is in crisis! According to the American Society of Civil Engineers, the estimated investment needed is $1 Trillion over the next 25 years for underground water infrastructure. This investment, as well as the ever-increasing cost of electricity, limited water supply, ever-decreasing natural resources, and environmental concerns, are driving the need for change. Change on how infrastructure is designed and constructed – utilizing more sustainable design and construction practices. ENVISION is designed to provide guidelines for these changes to North American infrastructure. In short, it is a rating system approach very similar to LEED Building Certification; however, with the focus on infrastructure.
Envision not only asks, ‘Are we doing the project right?’ but also, ‘Are we doing the right project?’
If you're like most people, you probably don't sit around thinking about how much Ductile iron pipe (DI pipe) weighs so in this Iron Strong Blog we are going to tell you where to find the weight of the pipe and why it is essential to familiarize yourself with the weight of the pipe.
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.
Jimmy sends a text to Bill, "I can't get into the virtual meeting." Bill replies, "You need to click on the link I sent you." Jimmy responds "Where is the link?" A frustrated Bill answers, "In the email about the meeting." A confused Jimmy asks, "On my computer? Bill answers again, "Yes! Is your computer on?" Jimmy fumbles to turn on his computer and texts Bill again, "OK, it is now. How do I get to the meeting?" Does this situation sound familiar to you? Have you ever explained something to someone only to realize that they knew less about the subject than you had previously assumed? In this episode of Iron Strong, we'll cover how to use an OD (Outside Diameter) Tape when measuring Ductile iron pipe.
Over the years, I have spoken with numerous engineers, utilities, and municipalities, and there seems to be a disconnect when it comes to the overall understanding of when and where cement-mortar-lined pipe can be used in wastewater applications. Due to these grey areas, engineers and owners often specify specialty linings for an entire project when the line could have been specified as either cement-mortar lined ductile iron pipe only or a mixture of specialty lined and cement-lined pipe.
Question – What is the difference between Ductile Iron and Polyvinyl Chloride (PVC)? Answer – Many things, but some groups may attempt to “muddy the waters” with inaccurate information regarding the two materials.
With the information that follows, we will take a closer look at what really separates Ductile Iron from PVC and why it matters.
As the name suggests, Long-Span pipe can extend over distances with fewer supports than conventional Ductile iron pipe (DI pipe). In standard 18-foot lengths of DI pipe, a minimum of one support is required within 2-feet of the Bell for each length of pipe. When using Long-Span pipe, distances of 27-foot up to 45-foot and longer can be achieved with support only at the Bell ends.
One question we often receive in the field is, "Can you use Ductile iron pipe (DI pipe) when running hot water or steam through pipe?" The answer to that question is YES, but there are several factors you must consider. For this Iron Strong Blog, we are going to look at these factors to help determine what products are needed for each application.
Recently, there have been multiple unsuccessful attempts by plastic pipe manufacturers and their trade associations to have legislation passed, mostly on the state level, requiring utilities to specify plastic pipes on their projects.
This legislation is a subject worth exploring deeper as it is being promoted by supporters of plastic and their lobbyists as a fiscally responsible requirement. Still, it provides no consideration for the many variables required in material selection or pipeline design; all are completely ignored in the proposed legislation which would ultimately be an "initial price only" comparison.
Every summer, I go backpacking with my family into the Uinta Mountains of Utah. The Uinta mountain range is enormous, very remote, and extremely beautiful. One of the most scenic areas in the entire range is called Red Castle. In this area of the Uintas rises a towering red monolith with peaks that reach straight into the sky, hence the name. Getting there requires a grueling 10-mile trek, but the beauty and serenity are well worth the effort...
