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?

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.
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.
Thermite welding, often referred to as CAD welding, on Ductile iron pipe (DI pipe) and products is a common practice in our industry today. This welding technique of using heat from an exothermic reaction to produce coalescence between two metals is most often used to bond the Ductile iron joints for cathodic protection or for the opportunity to add a cathodic protection system at a later date. In this Iron Strong Blog, we will discuss when, why, and how to properly CAD weld on DI pipe.
Dear Ditch Doctor
We recently installed a 15,000-ft 12-inch diameter Ductile iron pipeline with several 6-inch branches off two hydrants. The average depth of cover is 4 feet. The city engineer has expressed a concern that residual groundwater might have entered the pipeline during our installation activities.
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.
Have you ever wondered or asked if it is possible to order shorter lengths of bell and spigot Ductile iron pipe (DI pipe) for your waterworks project or sections within it? The answer is YES; we can help you with those shorter lengths of DI pipe for your project.
