Government Earmarks $11.5 Million for Building Research

The Department of Energy will spend $11.5 million on 16 research projects aimed at improving the energy performance of building envelopes and HVAC systems in U.S. homes. The Building America Industry Partnerships will underwrite research in three broad categories: advanced residential envelope and HVAC systems, fault analysis for residential HVAC systems, and how building industry standards affect energy performance. The announcement came from the Building Technologies Office (BTO), which is part of the Department of Energy’s Office of Energy Efficiency & Renewable Energy. The average American household spends more than $2,000 a year on energy bills, with U.S. homes accounting…


Green Tech and Rare Earth Elements

More aggressive recycling programs for discarded electronics would help recover the rare earth metals that allow them to operate. In contrast to the European Union, the U.S. has no laws that require manufacturers to accept these goods for recycling.

The recent Intergovernmental Panel on Climate Change (IPCC) report on climate change argued that we must cut global emissions in half by 2030 in order to meet the goal of keeping global warming to 1.5ºC as agreed to in Paris in 2015 at the Conference of the…


In the Growing Trend Toward Water-resistance, What Are My Insulating Options?

Corrosion under insulation (CUI) is a hot-button issue for the industrial industry, and rightfully so. Studies have shown that CUI is the cause of 40-60% of the money spent on piping maintenance in the oil and gas industry1. That’s no small sum, and that’s why many minds throughout the industry are working to find new solutions to help prevent or inhibit corrosion. This has often been done through finding methods to prevent water from contacting the surface of the pipe, like pipe coatings or water-resistant insulations. Water is frequently an integral component to pipe corrosion, thus inhibiting water contact can…


Mitigation of Corrosion Under Insulation (CUI) of Carbon Steel of Different Insulating Materials

Equipment often found in refineries may be enveloped in insulation and weathering jackets to maintain internal processing temperatures. In many cases moisture from the environment will penetrate the weathering jacket and infiltrate the insulation, leaching corrosive ions to the surface of metal equipment, effectively creating a corrosion cell. The goal of this project is to investigate different insulating materials for their ability to inhibit corrosion under insulation (CUI). The inhibiting mechanism utilizes water ingress that leaches ions from the insulator to bond with the surface metal and create a passive layer, inhibiting any further corrosion. This study will follow ASTM…


How to Detect and Prevent Corrosion Under Insulation in the Oil and Gas Industry

Corrosion under insulation (CUI) is one of the problems crippling the gas and oil industry. It can cost companies a lot of money every year in repair, inspections, and replacement costs. It refers to a form of corrosion that occurs between the material used for insulating gas lines and the outer surface of a pipeline. corrosion under insulation is the cause of most leaks experienced in the oil and gas industry. It is also one of the problems that companies in the gas and oil industry are struggling to address. Water will always seep into the insulating materials and eventually…


Stopping Corrosion Under Insulation in Global Oil and Gas Facilities

Corrosion under insulation (CUI) is the root cause of many of the global petrochemical industry’s most serious problems including forced shutdowns, lost production, early repair and replacement, as well as safety and environmental consequences that can cost millions of dollars per incident. CUI, which involves the corrosion of vessels or piping beneath insulation due to water penetration, is insidious because it can remain undetected until the insulation is removed for inspection or leaks occur. Water penetration can result from many causes including monsoons, rain, flooding, wash downs, and sprinkler systems, as well as exposure to steam, humidity or frequent condensation…
