... Abstract On 9 March 2000, a gasoline pipeline failed near Greenville, TX releasing approximately 12,000 barrels of fuel. After the on-scene portion of the investigation was completed, an 8.5 ft. (2.6 m) section of the 28 in. (71 cm) diam pipe was sent to the materials laboratory for examination...

... Abstract A newly installed pipeline leaked during cleaning prior to hydrotest at a pressure of approximately 400 psig. The intended hydrotest pressure was 750 psig. The pipeline was constructed from spiral-welded API 5L-X65 HSLA steel and was intended for seawater injection. Analysis included...

... to the 10-cm (4-in.) steel main to extend the main. Smaller service lines carried gas from the mains to the residences. Acommon maintenance practice on PE pipelines is the use of a bar clamp to squeeze the pipe flat whenever the flow of gas is to be stopped for down-stream maintenance. This greatly reduces...

... Abstract A section of pipe in a hydrocarbon pipeline was found to be leaking. The pipeline was installed several decades earlier and was protected by an external coating of extruded polyethylene and a cathodic protection system. The failed pipe section was made from API 5L X46 line pipe steel...

... Abstract A ring-type joint in a reactor pipeline for a hydrocracker unit had failed. Cracks were observed on the flange and the associated ring gasket during an inspection following a periodic shutdown of the unit. The components were manufactured from stabilized grades of austenitic stainless...
