There are occasions during field installation of Ductile iron pipe (DI pipe) when a Chamfered edge or a beveled edge may be required. There is typically a sharp edge on any metal pipe after field cutting. This edge is a safety hazard that requires removal. The sharp edge may also damage a gasket during installation, which is an additional reason to remove the sharp edge. Read on to see the differences and why it is essential to have the proper edge on a field-cut DI pipe.
All ductile iron pipe manufacturers use markings in a similar manner to assist customers in selecting the right material for the project. This includes verifying the material is suitable for the application intended (i.e. water or sewer) as well as adhering to the project requirements as stipulated by the owner/engineer for pipe class, lining, and exterior coating.
Because the colors used by each manufacturer may vary, we will explain how McWane Ductile applies these markings and describe their need and locations.
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.
When talking about ductile iron pipe in sewer applications, many times Induron’s Protecto 401™ comes to mind. Protecto 401 lining has often been the specified lining for ductile iron pipe in sewer applications more than 50 years.
Common uses for Protecto 401 are for a sewer force main that may not be fully running, where trapped air may exist, where chemical resistance is required, or for abrasion resistance. There may be occasions in the field when patching of the Protecto 401 lining may be necessary.
Every day around the world, Ductile iron pipe is being installed and used to provide individuals and families the luxury of having quick and easy access to clean water. From the manufacture to the contractor, the end goal is the same; that each pipe joint form a watertight seal after proper assembly.
A displaced or rolled gasket creating water loss in a ductile iron pipeline is one of the most common errors that occurs during joint assembly. Using the resources and experience of McWane Ductile’s long history of manufacturing iron pipe, this blog will provide some helpful tips regarding how to avoid this costly mistake when installing push-on joint pipe.
I have been on the road for nearly 20 years, talked with numerous contractors and distributors during that time, and there is a common question that I often get asked, "Why do Ductile iron pipe lengths vary?"
Those involved in the construction of water and wastewater pipelines are probably aware of the installation methodology of Horizontal Directional Drilling (HDD). HDD is a trenchless technique that provides an installation alternative offering several benefits over traditional open-cut. HDD can be implemented with minimal disruption to surface activities, requires less working space, and can be performed more quickly than open-cut methods. HDD can be used to install new pipelines or replace existing ones. Also, it can simplify or eliminate certain permitting processes. Although there are currently no national standards regarding HDD installations of municipal underground infrastructure systems, HDD has seen a dramatic increase in recent years and is becoming more common for any pipe material. HDD may be the fastest-growing trenchless construction method today.
When discussing Ductile iron pipe (DI pipe) in corrosion-resistant applications, glass-lined DI pipe often comes to mind. Glass lining has often been the specified lining for DI pipe in sewer and chemical resistant applications. Common uses for glass-lined pipe are for situations such as a sludge line in a wastewater treatment plant or when harmful chemicals are present in the pipeline. There may be occasions in the field when patching of the glass lining may be necessary.
In my previous experience, I’ve spent many hours operating numerous types of saws in various settings, such as felling a tree during seasonal work in my college years or emergency tree removal work in the aftermath of destructive storms while serving on a right-of-way crew. Whether you’re trimming a tree or cutting a piece of Ductile iron pipe (DI pipe), they share similarities, such as analyzing the situation, safety first, measuring twice, and cutting once.
