GTI has established a Gas Quality Resource Center (GQRC) to provide a common understanding and knowledge base about critical issues surrounding gas quality, interchangeability, and potential implications from the introduction of new supply sources into gas transmission and distribution systems. This centralized knowledge base encompasses extensive data resources and serves as a clearinghouse for information that…
Read MoreDeveloping energy efficiency solutions for residential housing A vision document, Natural Gas in a Smart Energy Future, sponsored by the American Gas Foundation, APGA Research Foundation, Canadian Gas Association, the INGAA Foundation Inc. and the Natural Gas Supply Association, was created by a GTI/Navigant Team in 2011. The report defines the ‘smart’ and ‘strategic’ roles…

Broadband Electromagnetic (BEM) technology offers a cost effective method for direct assessment evaluations through traditional excavations as well as keyhole openings. Researchers have developed a Full Encirclement Unit (FEU) using BEM sensors to measure wall loss on metal piping without the need to remove the coating. This new examination tool can enable internal and external…
Read MoreGTI associates, with funding from OTD, are collaborating closely with colleagues at SENSIT Technologies to bring new hardware that reduces O&M costs to market. The handheld acoustic-based pipe locator, named the Ultra-Trac® APL, is used to detect and locate both metallic and nonmetallic buried gas and sewer pipes prior to excavations and construction to reduce potential damage…

GTI is the industry’s source for the development, testing, and introduction of innovative keyhole technologies for utility system repairs and renovations. Excavation and restoration expenses cost U.S. natural gas companies more than $1 billion annually. GTI’s Keyhole Consortium—comprised of over 30 members from manufacturers and utilities—promotes the use of trenchless techniques that substantially decrease excavation and…
Read MorePolyamide 11 and 12 (PA11 and 12), thermoplastic materials, are excellent alternatives to steel pipe in high-pressure applications up to 250 psig. It is easier to install than steel and eliminates the need for costly long-term corrosion control measures. Two 2010 field trials coordinated by GTI—at Energy West in Montana and Atmos Energy in Mississippi—demonstrated…
Read MoreIn 2007, GTI initiated the GPS Consortium based on the need for a user’s group to facilitate the sharing of information related to the use of GPS technology for utility and pipeline operations. The Consortium is a cost-effective way for users to better understand this rapidly changing technology and how GPS can best be applied…

GTI’s hydro-testing alternatives program will identify and ultimately validate technologies that can provide an inspection that is equivalent to, or superior than, a hydro- test. The first phase of this program will characterize and quantify pipe that has not been subjected to a construction hydro-test to allow the selection of inspection technologies that could provide…
Read MoreGTI is creating a software tool to assist the pipeline industry in developing a strategic plan for developing and selecting inspection technologies. This inspection technology selection tool (in the form of a relational database) will assist operators in selecting the most appropriate inspection technology for a specific pipe segment to address the unique threats based…

To enhance the level of understanding of threats to infrastructure and allow operators to predict asset performance, calculate system risk, and maximize safety, research on potential threats and development of probabilistic models is needed to ensure that the current body of knowledge is leveraged and transferred into a useful set of tools. GTI is using…
