    Did you know there are two “new” ASTM standard specifications for metal jacketing?  If you haven’t heard this, don’t feel bad – you aren’t alone.  Our very own regional technical managers at JM IIG have commented that they have rarely met an owner, engineer, distributor, or contractor that has heard about these two new specifications, even though these standards have been in the industry for close to 5 years.  Despite their lack of notoriety, these standards are now available from ASTM, and they are worth reading and considering for your specifications to ensure that the jacket

    Insulation jacketing consists of an outer covering that is wrapped around tubing or pipe insulation to protect the insulation from moisture, wear and mechanical damage. The jacket also serves to provide support for the insulation and establish the system emissivity and appearance. Insulation jacketing plays an important role in the efficiency of the insulation.

    The type of jacketing used depends on the mechanical, chemical, thermal, and moisture conditions of the installation as well as cost and aesthetics requirements.

    Insulation is rarely installed as a stand-alone item. Instead, insulation material is part of a system that includes the insulation; the securement; a vapor barrier, in the case of low-temperature applications; and an outer layer that might be referred to as the cover, jacket or lagging.

    Jacketing applied over mechanical insulation can serve several purposes. Regardless of the type of jacketing and insulation, jacketing is used to ensure both the short-term and long-term performance of the insulation in the particular application. Assuming the jacketing is specified, manufactured, supplied, and installed correctly, over time it will only perform as designed if properly maintained.

    Johns Manville Industrial Insulation Group (JM IIG) offers two high-temperature industrial insulation products with exceptional compressive strength: Sproule WR-1200®, hydrophobic expanded perlite, and Thermo-1200™, water resistant calcium silicate. These materials have a number of similarities that make them ideal for many of the same applications, but there are some unique differences between the two that designers should consider when specifying either of these insulations.

    You've no doubt seen or heard a lot of discussion these days about the terms "digitization" and "digitalization," as well as some disagreement as to the difference between the two. Digitization seems to be the easier to define - basically taking an analog "thing" like a paper diagram or material safety data sheet (MSDS) and scanning it to make it digital. But, digitalization encompasses so much more than simply scanning paper documents.

    Advanced nuclear technology brought to fruition could produce electricity at an average levelized cost of electricity (LCOE) roughly 40% lower than conventional pressurized water reactors, according to a July 25 study by the Energy Innovation Reform Project and Energy Options Network (EON). “At these costs, nuclear would be effectively competitive with any other option for power generation.

    Any surface which is hotter than its surroundings will lose heat. The heat loss depends on many factors, but the surface temperature and its size are dominant. Putting the insulation on a hot surface will reduce the external surface temperature. By insulation, the surface will increase on circular pipes or vessels, but the relative effect of temperature reduction will be much greater and heat loss will be reduced. A similar situation occurs when the surface temperature is lower than its surroundings. In both cases some energy is lost.

    Industrial insulation contractors have their work cut out for them. As with many facets of industrial facility construction, operation, and maintenance, orchestrating the variables at play is critical to ensuring that projects are completed safely, on time, and to specification. For contractors, this effort can be complicated by coordinating timing with unforeseen project delays, space constraints, difficulty finding skilled installers, material storage limitations, and, most notably, inclement weather.

    Many pain-points of the subcontractor have been around for years, while many are just now surfacing. No matter the age of these issues, they are here and will effect the way subcontractors conduct business. Subcontractors face both internal and external pressures during their job and must react to both. They are responsible for their team and the general contractor as well as any outside pressures such as the environment, the law, and the government.
