There is a national effort to deny engineers, utilities, municipalities, public entities, and other waterworks professionals the ability to design water, wastewater, and stormwater projects in the manner that best serves the needs of their community. This effort focuses on water system piping but could be expanded to other infrastructure materials, as well. This blog contains a Q&A session conducted with a civil engineer, John Simpson, and a former utility manager, Roy Mundy, regarding Open Procurement.
Cast iron pipe was introduced to the United States in 1816. Since then, numerous other piping materials have been offered and utilized. None were able to supplant cast iron as the leading performer until Ductile iron pipe became available. The introduction of Ductile iron pipe (DI pipe) to the marketplace in 1955 remains among the most significant advancements in the history of the pressure pipe industry. It was quickly recognized as a pipe material with all the established durability of gray cast iron, yet with added strength and resiliency from its innate and lasting flexibility. It was first used for special and severe conditions of high pressure, such as where water hammer and excessive external loads might have existed.
As the name suggests, Ball & Socket River Crossing Pipe manufactured by McWane Ductile is a severe application Ductile iron pipe (DI pipe) product manufactured to meet the demanding requirements associated with crossing rivers, streams, and lakes. In this blog, we will discuss the various installation methods associated with Ball & Socket pipe and basic assembly instructions.
In recent years, an increasing number of locales and authorities have adopted greater controls of the water used in hydrostatic testing, flushing, and disinfection of utility pipelines, post-installation. Whether from a feeder hydrant to be metered, or when there might be a fee applied on the volume of water used, how does an engineer, contractor, or inspector compute the amount of water needed for these tasks? Sometimes it is required to demonstrate during flushing operations that the water inside a pipeline section has been “exchanged” a designated number of times during the specified flushing. So, just how much water does it take to fill or flush 1,500 feet of 12-inch class 52 DI pipe?
Celebrating Earth Day reminds us of the glorious surroundings we are provided with, bringing joy and happiness to our everyday lives. A variety of topographies span from rivers and streams to mountains and valleys. Even deserts and dry climate regions provide some of the most picturesque landscapes known to man. Earth Day is conveniently celebrated in the spring when flowers and trees burst with bountiful flowers and blooms. New life abounds as animals give birth to a new generation. A simple family picnic on a manicured lawn or trip down a mountain on a bike are just a couple of examples of pleasures we can enjoy.
This article takes a deeper dive into concepts outlined in the July 2020 entry prepared by my co-worker Gary Gula, How Much Does Ductile Iron Pipe Weigh and Why Does It Matter to You? Specifically, we will focus on the pipe weight itself, answering questions such as: From where do these weights originate? Why do we show weights on each pipe? How trustworthy are these weights as provided? And, What do these weights mean to me, the pipe customer?
Help Me Ditch Doctor,
The inspector on this pipeline project came out here and just told us we are laying pipe in the wrong direction. He said the bells have to face the other direction like the plans show. He wants us to dig up the 1,000 feet of pipe we've already installed and reverse each pipe. Is he for real? Does it really matter?
As a companion piece to the Iron Strong Blog entry, What Type of Ductile Iron Pipe Joint Is Right for You? by Scott Rhorick, this article takes a deeper dive into the specifics of installing restrained joint Ductile iron pipe (DI pipe) through a steel casing pipe. While many options are available industry-wide, this article concentrates on using TR Flex® or Sure Stop Gaskets in cased installations.
There are a variety of Ductile iron pipe (DI pipe) joints on the market. These different types of joint designs can now allow for additional benefits for various applications. Joining pipe together is just as important as the pipe itself. It sounds like a simple procedure, but the environment in which the pipe is assembled is critical.
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.
