• Proposed ASTM Standard for UV-Cured GRP Expected in 2018

    A proposed ASTM standard may bring a relatively unknown insulation jacket material into more projects in the United States. UV-cured glass-reinforced plastic (UV-GRP) is one insulation jacket option that has been used widely in Europe and Asia for more than a decade, and now an ASTM Task Group is spearheading an effort to create a

  • Case Study: Remediating Chilled-Water Pipe Insulation at a Football Stadium and Convention Center

    Author’s Note: “While Hurricane Harvey was devastating to some regions of Texas, to the best of my knowledge, the buildings mentioned in this article were not flooded by Hurricane Harvey. Even if the stadium and convention center had flooded, I engineered an insulation system that does not absorb water, so the system should not be

  • Engineers and Specifiers: Tools and Considerations for Insulation System Design and Material Selection

    The mechanical engineer has the responsibility for designing a commercial building’s mechanical system. This includes pipe, duct, and equipment used to distribute energy throughout the building. The objectives for insulating these components could be to save energy, maintain temperature control, protect personnel, or—on below-ambient systems—to prevent condensation. Most of the time there are multiple objectives

  • Specifications, Standards, and Product Data Sheets

    With any product you purchase, it is important to read the label and product data sheet (and assembly instructions, if any) before you purchase it. The data sheet provides you with the physical properties or specifications of the product, defines where or how the product should be used, and details the expected performance of the

  • IECC 2015 and ASHRAE 90.1-2013: Metal Building Envelope Updates You Need to Know

    The Next Code Cycle The next commercial energy code cycle for most states is the International Energy Conservation Code (IECC) 2015 code and ASHRAE 90.1-2013 alternative path. For some states, the new code has already gone into effect as of January 1, 2017, but the exact timing of implementation depends on each state. Remember that

  • Looking at Pre-Insulated Pipe Supports

    One of the most significant concerns for any plant engineer is how to save energy and operating costs. One way is by utilizing the appropriate pipe support components within the plant’s piping system. Choosing the wrong type of pipe supports can lead to extremely high costs, heat loss, corrosion under insulation (CUI), and a host

  • An Overview of the Structure of Insulated Pipe Supports

    When people ask me what I do for a living my response is, “Go inside any commercial building or garage and look up.” It may not be glamorous, but it is extremely important. The primary reason for insulated pipe supports is to support the weight of the pipe. The secondary reason is to provide continuous

  • Maintaining Insulation Integrity at Pipe Support Locations in Commercial Buildings

    Design engineers have utilized various methods to ensure the integrity of pipe insulation systems at pipe-support locations. The success of these methods depends heavily on the engineer’s foresight and understanding of the variables acting on the support location over the life of the system. In addition to the system requirements, optimal design and specification will

    Understanding Pitfalls that Can Slow Down the Installation Process

  • Zombie Specifications

    Is your boilerplate language up to date? When was the last time that you reviewed the insulation materials and system design that you recommend to clients? All too often in mechanical insulation system design specifications, the boilerplate language goes unrevised for long periods of time, even years.
