The crude truth about lining tanks for oil transport / Michael Mcglamry in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 36, N° 1 (01/2019)

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 36, N° 1 (01/2019) . - p. 22-23 Titre : The crude truth about lining tanks for oil transport Type de document : texte imprimé Auteurs : Michael Mcglamry, Auteur Année de publication : 2019 Article en page(s) : p. 22-23 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Citernes Corrosion chimique Index. décimale : 667.9 Revêtements et enduits Résumé : In the past, tank cars carrying crude oil had no protective linings for corrosion protection. Cargoes of light sweet crude (containing less than 0.5 percent sulfur) have a passivating effect on the steel of the cars, and very little corrosion was ever identified during routine inspections. why is there now significant concern about corrosion in railcars, when the industry has a track record (pun intended) of over 100 years with very low corrosion rates in unlined cars ? What has changed ? Is crude becoming more corrosive ? Are fracking chemicals mixing with the oil and corroding our steel ?

Electronic inspection of a field painting project / Cory Allen in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 36, N° 1 (01/2019)

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 36, N° 1 (01/2019) . - p. 24-30 Titre : Electronic inspection of a field painting project : Part 1 : Uncovering application issues Type de document : texte imprimé Auteurs : Cory Allen, Auteur Année de publication : 2019 Article en page(s) : p. 24-30 Langues : Américain (ame) Catégories : Contrôle technique Epaisseur -- Mesure Epoxydes Mesures électroniques Métaux -- Revêtements protecteurs Statistique Index. décimale : 667.9 Revêtements et enduits Résumé : Coating inspection has been made more efficient and effective through the use of electronic equipment, which can collect, store, transmit and populate inspection reports with data taken directly from the field. This article will not only outline some of the advantages of using electronic equipment on a real-world field painting project, but will also use the data generated to bring some important surface preparation and application considerations to the forefront.

DOTs on maintaining corroded connections : cleaning, caulking & cost / Tom Inglis in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 36, N° 1 (01/2019)

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 36, N° 1 (01/2019) . - p. 32-44 Titre : DOTs on maintaining corroded connections : cleaning, caulking & cost Type de document : texte imprimé Auteurs : Tom Inglis, Auteur ; Nick Volk, Auteur ; Dan Brydl, Auteur ; Kenneth A.

The Shade-Lohmann Bridge was scheduled for repainting during 2017 and 2018. Constructed in 1975, the Shade-Lohmann Bridge is a 3,473.5-foot-long, fracture-critical, 16-span twin girder with an 1,140-foot cantilever truss. Because of the intricate design of the bridge, District 4 decided that connections should be caulked to provide additional protection because many were exhibiting substantial corrosion. District engineers had heard of both successes and failures when caulking was used and decided it was important to better understand the use of caulking and to develop plan notes or special provisions to clearly delineate expectations. Before developing plan notes, District 4 wanted to identify which surfaces should be caulked, the extent of surface preparation that should be required, and at what point in the application sequence the caulking should be installed. Tom Inglis and Nick Volk of District 4 reached out to other states for copies of their specifications and subsequently, Dan Brydl of FHWA-Illinois Division reached out to his counterparts for additional information. Ken Trimber of KTA-Tator, Inc., a coatings consulting firm under contract with IDOT, was engaged to assist with the final review. This article outlines the specification language provided by the states that were contacted, summarizes the various approaches that are taken and presents the process followed by IDOT for the Shade-Lohmann Bridge.

Putting the pieces together / Kevin H. Keith in JOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL), Vol. 36, N° 1 (01/2019)

[article]  inJOURNAL OF PROTECTIVE COATINGS & LININGS (JPCL) > Vol. 36, N° 1 (01/2019) . - p. 46-55 Titre : Putting the pieces together : Integrating steel repairs with bridge painting projects Type de document : texte imprimé Auteurs : Kevin H. Keith, Auteur Année de publication : 2019 Article en page(s) : p. 46-55 Langues : Américain (ame) Catégories : Métaux -- Revêtements protecteurs Ponts -- entretien et réparations Ponts métalliques -- Revêtements protecteurs Index. décimale : 667.9 Revêtements et enduits Résumé : There are a significant number of recommendations for combining steel repairs with bridge painting projects. A key factor to remember is that painting and repairs have to work together as a system. All parties should understand the details of the entire system in order to specify and install them correctly. Many detail decisions have schedule and cost considerations in addition to technical considerations. Thus, active leadership and cooperation from everyone involved is required because it is next to impossible to have a perfect design or a bridge without unforeseen deficiencies. Deliberate planning and communication at every step will help to ensure that steel repairs are done correctly.
