Plastic Pipe Field Failures Catalog
Information obtained from GRI's extensive research program on field failures of gas distribution plastic pipe.$400.00 -
Internal Corrosion Direct Assessment of Gas Transmission Pipelines—Methodology
The basis behind ICDA is that detailed examination of locations along a pipeline where an electrolyte such as water would first accumulate provides information about the remaining length of pipe.$295.00 -
Atmospheric Rich/Lean (ARL) Method for Determining Glycol Dehydrator Emissions
In this program, the atmospheric rich/lean sampling and analytical method (ARL method) was used to determine the emissions from the regenerator still vent of triethylene glycol (TEG) dehydrators of natural gas.$295.00 -
Meter Measurement Accuracy at Conditions from Atmospheric Air to 700 psig Natural Gas
The objective of this report is to provide independent turbine meter performance data to support the planned revision of the American Gas Association (AGA) turbine meter standard, AGA Report No. 7. Eight commercial turbine meters were tested in natural gas and air to quantify changes in meter calibration with changes in line pressure.$495.00 -
Metering Research Facility Program: Effects of Turbine Meter Cartridge Change-out on Measurement Uncertainty
Tests were performed at the SwRI Metering Research Facility Low Pressure Loop to quantify changes in turbine meter calibration due to industry cartridge change-out practices. Tests involved four models of natural gas turbine meters, and included meters with standard and high flow capacities, single-rotor and dual-rotor meters, and new and used meters$295.00 -
External Corrosion Direct Assessment (ECDA) Implementation Protocol
The Gas Technology Institute (GTI) and the American Gas Association (AGA) have developed a collaborative research program to help Local Distribution Companies who operate high-pressure natural gas transmission lines understand the methods and procedures to perform integrity assessments and meet government-imposed regulations.$295.00 -
Schedule of Responses to Corrosion-Caused Metal Loss Revealed by Integrity-Assessment Results
This report presents a schedule for responses by a gas pipeline operator to the receipt of corrosion defect information from a pipeline integrity assessment. The schedules are intended to apply to pipeline assessments relating to external or internal corrosion-caused metal loss.$295.00 -
Electrostatic Discharger System for Polyethylene Pipes in Gas Distribution: Phase I
Internal charge generated by particulates in gas flowing through polyethylene (PE) pipes induces exterior charge of opposite polarity. High external charge buildup can produce spark discharges to nearby objects.$295.00 -
Characterization and Measurement of Natural Gas Trace Constituents Volume II: Natural Gas Survey
A program to survey the detailed composition of pipeline gas from several major producing areas of the United States, imported Canadian gas, and natural gas used to generate electricity at four power plants is reported. It was conducted to assess the possible presence and concentration of certain trace constituents having potential impact on the operation, utilization, and environmental aspects of natural gas. Many achievements and products resulted from this project.$295.00 -
Remote and Automatic Main Line Valve Technology Assessment
The capabilities of current automatic and remote-controlled valves for natural gas transmission pipeline break control are documented. The reliability of current break detection methods is limited due to the difficulty in distinguishing a line break from other transient operating conditions.$295.00 -
Volume 1: Users' Guide on Squeeze-Off of Polyethylene Gas Pipes
This volume presents the results in the form of easy-to-use guidelines. Squeeze-offs are performed on polyethylene gas pipes to stop gas flow when downstream repairs are needed. Occasionally damage is initiated and later failure occurs by a slow crack growth mechanism. To prevent this, it is necessary to know which conditions induce damage, how to identify materials susceptible to damage, what guidelines exist for good squeeze-off procedures, and which tool designs can avoid or minimize damage.$295.00 -
Volume 2: Technical Reference on Squeeze-Off of Polyethylene Gas Pipes
This volume provides detailed description of experiments, analysis, test data, and conclusions. Squeeze-offs are performed on polyethylene gas pipes to stop gas flow when downstream repairs are needed. Occasionally damage is initiated and later failure occurs by a slow crack growth mechanism. To prevent this, it is necessary to know which conditions induce damage, how to identify materials susceptible to damage, what guidelines exist for good squeeze-off procedures, and which tool designs can avoid or minimize damage.$295.00
