Radial Welded-on Outlets, Tangential Outlets, Bossed Outlets, and Thread-O-Lets. Have you ever been involved in a project utilizing one of the various pipe outlet configurations? If so, you are likely aware of the special care these products require. If you haven’t been involved in a project requiring outlet piping, then within this blog we will explain the types of outlets available and the importance of the unloading, storage, and installation process.
Ductile Iron (DI pipe) was first used in the United States as early as 1950's. Since iron pipe was one of the earliest pipe materials to be used in modern water works and wastewater systems, most early fittings and couplings were designed to be used on Grey Cast and then Ductile iron pipe.
So, connecting “other” piping material to DI pipe is very straightforward on the Ductile pipe side of the fitting. The most important item to consider is on the other material side of the connection.
The normal, stocking item for Ductile iron pipe products is lined and coated with a sealcoat that comes in your choice of black. Many water professionals wonder about the purpose of this coating, or paint, that gives Ductile iron pipe it’s familiar appearance. In this article we offer some explanation and history behind the application and advancement of the sealcoat.
Gaskets are a critical component in your ductile iron piping system. To get the full benefit of your gaskets, they need to be stored in a manner that minimizes deterioration. We don’t always work in favorable conditions, so no matter if you are in the field or in a warehouse, utilizing the best storage practices and locations are key to the performance and the effective lifetime of your gaskets.
In this article, we will cover some guidelines on how to store and care for your gaskets. We will cover the “what to do” as well as the equally important,”what not to do.”
It is pretty much a daily occurrence here at McWane Ductile for our sales staff to receive price requests on a variety of ductile iron pipe (DI pipe) products. Usually this request is for a specific project, but occasionally design engineers will also ask for “budget pricing” for future underground utility projects. This is typically a pretty simple task, but to provide the most accurate and cost-effective pricing, there are a few items that must be addressed that will ultimately determine the final cost to the customer. This article will review some of those variables that determine the final pricing for your DI pipe needs.
Ductile iron pipe (DIP) is one of the most widely used pipe materials in North America. The Design Life is second to no other pipe material due to its robust design. This pipe material is the strongest and most resilient available for water and wastewater utilities providing unparalleled Life-Cycle value.
In many areas, utilities need to consider how to protect these valuable pipelines from corrosive soils. The question is “How can we economically protect these pipelines to meet or exceed the 105-110 year average design life of DIP?”
Even in this modern era, we are still concerned with many of the issues that early civilizations faced when providing water to our communities, such as supply and demand, pipeline construction and upkeep, cleanliness, conservation and cost. In the fall of 2018, McWane Ductile’s Senior Regional Engineer, Roy Mundy, had the opportunity to interview Consolidated Utility District General Manager Bill Dunnill. The two gentlemen, both with utility management experience, had a candid conversation about Bill’s day-to-day challenges, successes and his preferred choice of pipeline material. The following are excerpts from their discussion.
Today there are several funding methods and sources for water and wastewater projects, not only in the United States but throughout the world. Most, if not all, require some sort of report or project summary. You may have seen these with such names as Conceptual Design or Engineering Report, Facilities Needs Assessment, Preliminary Design Report, Preliminary Engineering Report. Different agencies and different countries have different names for these respective documents, but most are like each other in scope and requirements.
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.
Picture This
Much time, effort, and care have been expended installing a water line. Crews have worked through inclement weather. Unexpected rock was found, which slowed progress but did not stop installation of the pipe. Crews have worked long hours to meet deadlines and are anticipating the end of the project.
But wait, you have not pressurized the line. All eyes are on that gauge in hopes of validating the work was successfully completed.
