Pipe Expansion Loop Design
Pipe Expansion Loop Design Published January 2023 Keywords Expansion Loops Piping Flexibility Stress Compensation Summary The purpose of this file is to illustrate quick sizing of the expansion loops. Pipe expands when heated and contracts when cooled. When a pipe allowed to move (unrestrained), it is free to expand or contract without generating thermal stresses. Once the pipe is restrained at the ends (by anchors or equipment nozzles), thermal stresses can be generated. These stresses are a result of a system’s lack of flexibility and ability to compensate for thermal expansion or contraction. Expansion compensation in the form of expansion loops, 90° elbows and z-bends are a simple, low cost and low maintenance design elements that can be used to increase system flexibility and decrease pipe stresses. These arrangements can be observer in Figure 1. Hints 90° changes in piping direction are the most efficient design to absorb thermal expansion/contraction. Utilize any natural flexibility of the piping system (any lateral offsets, changes of direction). Use strategic location for the pipe supports to avoid over restriction of the system. Share [...]
DAF unit replacement supports major plant expansion
A local waste oil recycling plant has recently purchased another FS-30 to replace an existing DAF unit to support a major plant expansion. Prior to this purchase they used a JNE Environmental FS-30 DAF to pre-treat their wastewater through the use of JNE 3111C dewatering polymer, and then through the use of JNE 709 and JNE 3003 to produce a flocculated wastewater.
Engineering Wall of Fame Inducts Joe Ng
Joe Ng, the man behind the multi-continent, multi-industry JNE Group of Companies officially inducted into UNB's Engineering Wall of Fame. In 1968, Dr. Ng arrived in Canada to study electrical engineering, spending his first two years at the University of Prince Edward Island and then transferring to UNB to complete his engineering degree.
Ontario award for immigrant employment
Ontario is recognizing the first ever recipients of the Ontario Award for Leadership in Immigrant Employment, for their role in championing diversity and supporting jobs in their communities. Five outstanding recipients from across the province were honoured during a ceremony at the 2013 Ontario Economic Summit in Niagara-on-the-Lake.
Honorary Doctor of Science Degree — UNB
Joseph Ng, Chair of the JNE Group of Companies, proudly received an Honorary Doctor of Science Degree from the University of New Brunswick. Joe had previously graduated from the University with a degree in Electrical Engineering in 1973. He was honoured to receive this most recent Degree in the presence of its current graduating class along with his family. Congratulations Joe!
New Office Grand Opening in Livonia, Michigan!
JNE Consulting celebrated a new milestone earlier this month with the grand opening of a multi-discipline engineering office in Livonia, Michigan. The grand opening was a great opportunity to formally introduce our new local team members to clients in the area, establishing new connections while celebrating our existing client relationships.
Steel Plant — Excavation and Shoring Progress
A unique advantage of working with The JNE Group of Companies is the close collaboration between our engineering and construction teams. This project, a JNE Consulting and Triple Crown Enterprises (TCE) joint effort, sees these teams working together to complete the design and construction of massive equipment foundations for a steel plant, including excavation, shoring, piling, and concrete work.
Automated Polymer Make-Down Units Improve Wastewater Treatment Efficiency
An environmental and sustainability solutions group approached JNE Environmental to supply two PM-2000 polymer make-down units as components to a larger wastewater treatment system. JNE Environmental was selected for the project because of the smaller physical footprint of our units, as well as very competitive cost.
