This article reviews several applications for the Rate Process Method (RPM) such as validation of the PE material hydrostatic design basis per ASTM D 2837 and service life forecast of older-generation PE pipe still in service and correlation with actual field failures.
This is a story of how GE’s SmartLaunch™ system made in-line inspection (ILI) possible in “unpiggable lines” beneath the streets of New York.
Energy Control Systems, Inc. (ECSI) says it has developed and has applied for a patent for a new service riser designed to identify and vent leaking fuel gas.
The distribution of natural gas in an urban utility has inherent risks. Distribution networks are located underground, out of sight and typically under pavement in close proximity to buildings, residences and subsurface structures.
As traditional natural gas reservoirs are depleted, producers are forced to target lower pressure wells that typically produce a “wet gas.”
Polyethylene (PE) is the primary material used for gas pipe applications. Because of its flexibility, ease of joining and long-term durability, along with lower installed cost and lack of corrosion, gas companies want to install PE pipe instead of steel pipe in larger diameters and higher pressures. As a result, rapid crack propagation (RCP) is becoming a more important property of PE materials.
