Through the years, across the country, contractors, engineers, authorities, and customers routinely ask questions that seem basic yet truly speak to the fundamental versatility of Ductile iron pipe (DI pipe). Among the most popular questions are:
Even at the height of summer construction, casting pipe, and filling orders for more pipe, there's always time to take a moment to spotlight some of the great partnerships McWane Ductile has developed over the years. Once such partnership is that with Legacy Water Group who recently completed a water pipeline project in Athens, Alabama. This #IronStrong Blog quickly describes some of the highlights from the project.
In my career with McWane Ductile, I've sold my fair share of polywrap, but the one thing that I haven't really thought about when selling polywrap is the tape needed to complete the installation. I'm not sure why this is. Maybe the biggest reason is I wasn't sure how much tape was required for each roll of polywrap I sold. Therefore, I wanted to take a deep dive into this subject to make it easier for people to know when ordering polywrap how much tape they need to purchase as well.
Have you ever been so taken aback by the structure of a question that your first thought is, “say what? Did they really just ask me that?” In the vernacular-sensitive world of utility pipelines, it happens more often than you might think.
Have you ever been on a Ductile iron pipe (DI pipe) installation with restrained joint gaskets and needed to uninstall a previously assembled joint? This is normally prompted by the need to replace a displaced or a “pinched” gasket. Proper gasket placement and attention during assembly is the best way to avoid such conditions, as detailed in a previous blog by McWane Ductile. Unfortunately, the problem often does not arise until the pipeline is hydrostatically tested. In today’s Iron Strong Blog, we will examine the “Dos & Don'ts" of uninstalling with DI pipe restrained joint gaskets.
Have you ever been asked what size trench is needed when installing Ductile iron pipe (DI pipe)? How safe are the working conditions within a trench? Knowing the proper trench to utilize during the installation of the material will help save time, effort, and money on any job site. But most importantly, this knowledge will help keep everyone safe within and around the trench. The Occupational Health and Safety Administration (OSHA) has gone to great lengths to define and identify any threats in the trenching and excavation safety when installing DI pipe. This Iron Strong Blog will share and explain the different trenches available while outlining the safety considerations required when excavating earthen material.
Utility pipelines provide for some of the most basic needs within our society. Essential services, such as supplying potable drinking water to our homes and businesses or sending wastewater away, are possible because of a network of buried pipelines. Whatever pipeline materials are used, they are expected to meet minimum service qualities such as withstanding leakage. This resiliency to leakage eliminates waste of our precious drinking water and prevents polluted soils from wastewater in the pipeline's proximity.
When I first started my engineering career, I was placed in charge of coordinating the relocation of water transmission and distribution pipelines to accommodate the construction of an interstate highway through a city of approximately 180,000 residents. Many times, these projects required pre-poured thrust block restraints due to the amended connections between new and old waterlines in a short timeframe so as not to leave customers inordinately out of water for long periods of time.
Shallow aquifers prone to contamination, compliance with federal drinking water standards, and insufficient resources to replace aging infrastructure. These are some of the water issues that launched the creation of the Lewis & Clark Regional Water System and the construction of the Iowa Treated Water Pipeline – Segment 3.
Dear Ditch Doctor: Out here in the western United States, we wind up with a lot of pipelines installed up or down serious hills, dare I say mountains as well? We are good at the construction part, yet time after time we struggle with getting a satisfactory post-installation hydrostatic test on the pipeline, especially with inclined installations. Often the pipeline drops anywhere from 20 to 50 psi on the gauge and can do that several times or more until we take some sort of drastic redo/restart on the test procedures.
