    When Giffin Sheet Metals Ltd. needed a large quantity of aluminized steel for an automotive project in Alliston, Ontario, the Toronto contractor reached out to a U.S. supplier in southeastern Michigan.Aluminized steel is harder to come by in Canada and the company required several hundred thousand pounds. It was a transaction the 70-year-old company had done many times before, and with the 24-year-old North American Free Trade Agreement, such cross-border purchases were virtually hassle-free.more...

    With the recent political whirlwind that has permeated the HVAC industry, many suppliers, manufacturers and contractors are in a state of flux. We are all waiting to see how things play out in the metals market after Trump administration’s March 8 announcement of new import tariffs on steel and aluminum.more...

    Last week, we hosted CUI Test Results: Understanding the Corrosive Mechanism, a live webinar detailing the latest test results from the most recent long-term corrosion under insulation (CUI) testing. Our webinar covered the various types of corrosion, the science behind the thermodynamics of corrosion, and the latest findings from long-term corrosion research on Thermo-1200™ calcium silicate, and Sproule WR-1200® expanded perlite, and a silica aerogel blanket specimen.more...

    Galvanic corrosion (also called bimetallic corrosion) is a deteriorative electrochemical process that occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte. This type of corrosion is characterized by the accelerated corrosion of one metal, while the other remains mostly unaffected. In other words, one metal becomes the anode and corrodes preferentially, thus sacrificing itself while protecting the other metal, the cathode.more...

    When it comes to corrosion under insulation (CUI), I tend to call it a "minefield," and for more than one reason. It’s not only a hidden phenomenon, but it's also one that can really come back to bite companies who don’t invest in a good CUI mitigation strategy, because sooner or later, those companies are going to get their names in the papers due to unwanted accidents, production loss and environmental damages. more...

    Guided Wave Ultrasonic Testing (GUL), or Long Range Ultrasonic Testing (LRUT), is considered a viable screening approach for detecting CUI related problems in the oil and gas industry. Guided wave ultrasonic testing is a nondestructive inspection method in which low-frequency omnidirectional ultrasonic waves propagate along internal geometric boundaries, in order to detect corrosion. As the guided waves travel across the confined boundaries, the waves will then be reflected at areas with crossmore...

    Last month, we published a blog titled Accelerated System Corrosion Testing with Calcium Silicate and Perlite Insulations.  The blog reviewed the developing NACE TG 516 protocol and results from the accelerated corrosion testing that Johns Manville completed on a pipe assembly insulated with our Thermo-1200™ and Sproule WR-1200® rigid insulation products. more...

    Corrosion impacts our society on a daily basis. Automobiles, buildings, infrastructure, appliances and energy distribution systems are examples of some of the components negatively affected by this phenomena.Corrosion is defined as the deterioration of a material as a result of chemical reactions between it and the surrounding environment. Although corrosion affects a variety of materials including polymers and ceramics, the term is most often associated with the degradation ofmore...

    Annually, the impacts of corroding materials cost the global economy over $1 trillion. Some alloys are exposed to extreme temperatures and stress, causing the formation of an oxide film, which in turn accelerates the breakdown of the alloys.more...
