Hoop Stress
Hoop stress is the stress that occurs along the pipe's circumference when pressure is applied. Hoop stress acts perpendicular to the axial direction. Hoop stresses are tensile and generated to resist the bursting effect that results from the application of pressure.Three principal stresses...
Nominal Diameter
Nominal Diameter is also known as the mean or average outside diameter and is represented by DN. It is neither equal to the inner diameter (ID) nor the outer diameter (OD) of the pipe. Nominal is a word that denotes non-specificity and in this case, identifies the approximate inner diameter with a...
Invert level
An invert level is defined as the elevation of the inside-bottom of a pipe, trench, culvert, or tunnel. It may also be considered the "floor level" of a pipe.Invert levels are essential for assessing the flow in a piping system. For example, the invert of a municipal sewer connection can...

What’s the difference between microtunneling vs. guided boring?
Microtunneling and guided boring are often erroneously used interchangeably in the construction industry. While both these trenchless boring methods may seem identical, there are a number of key differences between the two that need to be considered when deciding which technology is better suited...

Why is horizontal directional drilling better for the environment?
Horizontal directional drilling (HDD), also known as directional boring or horizontal earth boring, involves using a surface drilling rig to install underground pipes, conduits, cables and any other utility in a shallow arc along a predefined bore path. This technique is so named due to its ability...

What are some of the new trenchless technologies being used to minimize carbon emissions?
The construction industry has been in the spotlight forever when it comes to carbon emissions. Construction accounts for almost 1/3rd of global energy consumption, and thus is responsible for the same amount of carbon dioxide emissions.To minimize the global carbon footprint left behind by the...
