Modification of Surface Properties of Metals by Sol-Gel Coatings

Available for download

The surface properties of metals can be modified by using thin hybrid coatings without changing the metallic look of the surface. These properties include for example anti-fouling, abrasive resistance and corrosion resistance.

New Disposable Spray Systems: Quick to Change, Quick to Clean, Quick to Coat

Product Number: 41205-182-SG

Author: Anthony R. Martucci

Publication Date: 2005

$20.00

People have been spraying two-component materials for decades. Some processes are very rudimentary, such as mixing by hand and brushing the material on the surface. More recent techniques would be impingement mixing the material (using air to force the materials together and then spraying the material on the surface).

Failure Investigation of Internal Girth Weld Coating Surface Preparation: A Case Study

Product Number: MPWT19-14360

Author: Rashed Alhajri, Yousef Alrayes, Fahad Alhindas, Ghassan Bahamden

Publication Date: 2019

$0.00

During the construction of a 56km long 16 in. carbon steel sour gas pipeline, repetitive surface
preparation failures were detected during visual inspection of pipeline girth weld internal surface prior to
coating application. Such failures represented 67% of the total pipeline girth welds and were manifested
by excessive sharp-edges at the root pass. To identify the failure causes, an investigation was
performed through reviewing the pipeline, fabrication and coating application specifications and
procedures, quality control records and performing an extensive visual inspection through an advanced
video robotic crawler on all pipeline girth welds made. Upon investigation analysis, the failures were
caused by sharp-edges in the root pass which were attributed to improper practices during
manufacturing, field fabrication and pre-coating quality control. The failure analysis indicated that the
mechanized Gas Metal Arc Welding process, with the parameters used, was not suitable for internal
girth weld coating application. In addition, a more stringent requirement should be applied to the
acceptable pipe-end diameter tolerance and pre-coating quality control to ensure absence of similar
premature surface preparation failures. The pre-coating quality control can be improved through
utilization of robotic laser contour mapping crawler for precise detection and sizing of unsatisfactory
surface weldment defects, including sharp edges.
