The Truth About TG - The Measurement and Significance of the Glass Transition Temperature

Product Number: 41206-290-SG
Author: Dwight G. Weldon
Publication Date: 2006
$20.00

The glass transition temperature (Tg) is an important property, as it is a reflection of both the type of resins in a coating and its degree of cure. This paper discusses what Tg is, the measurement of Tg, and its relationship to coating performance. Data is presented which indicates that the performance of a coating may depend on the conditions under which it is cured, such that the exact same coating may perform differently depending on the region of the country in which it is used and the time of year in which it is applied.

The Ultrasonically Induced Cavitation Erosion of Fiber Glass Reinforced Epoxy and Nodular Cast Iron (NCI) in Seawater

An investigation was carried out to study and compare the cavitation erosion behavior of a non-metallic fiber glass reinforced epoxy system and a metallic nodular cast iron (UNS F32800) alloy utilizing an ultrasonically induced cavitation facility in seawater. The cavitation tests were made at a frequency of 20 KHz as per ASTM-G30-90 and at a temperature of 250C. the cavitation action increased the rate of mass loss of both the fiber glass reinforced epoxy and that of the UNS F32800 by several orders of magnitude with respect to stagnant conditions. Cavitation also made the surfaces of the fiber glass reinforced epoxy and UNS F32800 very rough exhibiting large cavity pit in the region of the attacked area as revealed by the scanning electron microscope (SEM). The main mechanisms of failure for the fiber glass epoxy system was due to loss of adhesion of the matrix / fiber glass interface and subsequent removal of the resin as well as glass fibers by the mechanical action of cavitation. However the failure of UNS F32800 was due to severe plastic deformation and the fragmentation of the graphite nodules . Mechanical factors and surface defects were determined to be the leading cause of resin and glass fiber loss for the epoxy system and micro-galvanic activities between the ferrite matrix and graphite nodules for the UNS F32800.

Looking at martensitic stainless steels (MSS) NACE MR0175 / ISO 15156 lists six tables with different H2S acceptance levels. Generic Table A.18 lists several MSS with a maximum allowable partial pressure H2S of 0.1 bar whilst equipment specific Table A.23 (Wellhead and tree components and valve and choke components) shows no restrictions when it comes to partial pressure H2S.To substantiate the applicability of Table A.23 a study was performed to evaluate environmentally-assisted cracking resistance of cast alloy CA6NM (UNS J91540) in highly sour environments (Level VII) and the implications of the findings on the usage of CA6NM as pressure containing valve bodies in wellheads.After that a ballot (no. 2013-03) was written to clarify the scope of Table A.23 and limit the use of cast alloy CA6NM (UNS J91540) based on applied in situ stress. An additional note was incorporated for UNS J91540; "Low-carbon martensitic stainless steel J91540; the maximum design tensile stress shall not exceed 2/3 specified minimum yield strength or 345 MPa (50 ksi) whichever is less." The presentation will include field history a historic perspective of NACE MR0175 results of NACE level VII tests the ballot process including an FEA study to simulate stress distribution in valves for wellhead equipment.

In November 2004 ISO 19840 was published to provide a consistent method for the measurement of coatings applied to structural steel for corrosion prevention. This new standard includes methods for the adjustment of gauges to take account of surface roughness, the designation of inspection areas and the use of acceptance criteria.

The Use of VCI Inhibitors in Conjunction with or Replacement of Traditional Corrosion Inhibitors

Publication Date: 2019
$20.00

The use of traditional corrosion inhibitors in paints and coatings continues to be challenged from both an environmental and performance aspect. End users are demanding better corrosion performance and in many cases this cannot be achieved with traditional zinc or chromate type inhibitors. The use of VCIs(vapor corrosion inhibitors) in coating formulations has shown that in many systems they can replace the older technology or significantly improve the performance of the system by working in synergy with the existing inhibitors.
