Whenever liquid flows by gravity out of a vessel or down a pipe there is a potential problem of entrainment of gas by the liquid. Entrained gas not only raises the pressure drop but also reduces the static head available to drive the flow and overcome the created pressure drop. These effects can reduce the flowrate drastically below the design value.
Emergency lighting intended to provide illumination for evacuating a building/plant in the event of failure of normal power supply is considered to be part of the Life Safety System.
When sizing a room, or an area that will house electrical equipment, there are many variables to consider. It is clearly stated in the Ontario Electrical Code book that “electrical equipment shall be installed and guarded so that adequate provision is made for the safety of persons and property and for the protection of the electrical equipment from mechanical or other damage to which it is likely to be exposed” (OESC 2-200). This can be done with a dedicated electrical room/space, signage, physical barriers, and training. When working with other disciplines, the electrical team must communicate the physical size, and space needed to follow all of the rules stated in the OESC, of the chosen electrical equipment.
The purpose of this knowledge file is to provide a basic overview of what a pre-start health and safety review (PSR or PSHSR) is in order to facilitate the planning and coordination of PSR projects.
The purpose of this file is to share information on trunnion supports. Sometimes in piping design, a trunnion is needed. When designing a trunnion, there are many factors to consider and best practices to follow.
This is an initiative to provide students within the Introduction to Civil Engineering course the opportunity to engage in hands-on, real-world learning experiences. This announcement coincides with the 25th anniversary of JNE's establishment of the Endowed Chair in Civil Engineering at McMaster's Faculty of Engineering.
In early November, JNE hosted a group of students from the McMaster University CIVENG2X03 program to tour 176 Shaw Street and the TCE fabrication shop. A unique aspect of the walkthrough included a visit to our fab shop, which provided the students with a clear and tangible view of the entire steel fabrication process from design to creation.
Representatives of the JNE Group of Companies attended the Specialty & Agro Chemicals America event — a forum that promotes chemical manufacturing, chemical technologies, and related chemical industry services that have specific applications for the agrochemical and specialty chemical markets — in Savannah, Georgia in July 2025.
The intent of this knowledge file is to study the velocity limitation and material selection considerations in an oxygen system as per CGA G-4.4 code for oxygen piping systems to mitigate the risk of oxygen fires/explosions.
Representatives of the JNE Group of Companies are attending the AIST Women In Steel Conference in Pittsburgh, Pennsylvania from September 16–18, 2024. The second annual conference is a two-and-a-half day event supporting recruitment, engagement, and professional development of women in the global steel industry.
