TECHNICAL PAPER: MINIMIZING THE IMPACT OF LIGHTNING STRIKES ON GAS PIPING SYSTEMS
This paper explains the nature of lightning strikes and the type of damage that can occur from direct and indirect strikes. Gas piping systems have experienced a significant number of strikes over the past few years that have resulted in damage to the piping and small gas leaks. The complete elimination of lightning strike damage requires the installation of a lightning protection system. However, this is outside the current requirements of the building and electrical codes. In stead, more robust bonding of the gas piping system to the electrical system grounding system is necessary to minimize the occurrence and extent of lightning-induced damage. The paper reviews the procedures for the sizing and installation of a direct bonding system for gas piping.

TECHNICAL PAPER: ADVANCED INSPECTION ROBOT FOR UNPIGGABLE PIPELINES
The National Energy Technology Laboratory of the US Department of Energy, under Award DEFC26-02NT41645, and the NYSEARCH Committee of the Northeast Gas Association (previous the New York Gas Group), sponsored research to develop a robotic pipeline inspection system capable of navigation through the typical obstacles that make transmission and distribution pipelines unpiggable. The research contractors, Foster-Miller and GE Energy performed an engineering study and developed a conceptual design that met all the requirements for navigating and inspecting unpiggable transmission pipelines. Building on Foster-Miller's previous efforts developing the Pipe Mouse robot, the RoboScan inspection robot (Figure-1) meets the navigational challenges of unpiggable pipelines by utilizing four, self-adjusting locomotive units, integrating an innovative segmented MFL inspection module, and incorporating auto-correcting inter-module couplings.
TECHNICAL PAPER: RESULTS FROM 20 YEARS OF RESEARCH ON INTERIOR GAS DISTRIBUTION TECHNOLOGIES
Over the last 20 years, the gas industry has experienced many changes in the way natural gas is distributed within residential and commercial buildings. One of the most radical departures from traditional practice is the elevated pressure, corrugated stainless steel tubing (CSST) system. Research results have shown that elevated pressure CSST systems are less expensive to install; provide the consumer with enhanced features not available with conventional low pressure steel piping systems; and provide future expansion options. In the single-family market, these features have successfully increased the gas load per installation. The retrofit of CSST with installed low-pressure, steel pipe systems also encourages more gas usage.
