Proposed Crack Growth Rate Disposition Curves For Stress Corrosion Cracking Of Alloy 82 In BWR Environments

Product Number: ED22-18349-SG

Author: Peter L. Andresen, Robert G. Carter, Katsuhiko Kumagai

Publication Date: 2022

SCC in Fe- and Ni-base alloys has been observed in high temperature water, both in the laboratory tests and in BWRs. SCC results from complex interactions of ~10 primary variables and hundreds of secondary variables, broadly categorized in terms of stress, environment and microstructure.

Proposed Crack Growth Rate Disposition Curves For Stress Corrosion Cracking Of Alloy 82 In BWR Environments

Product Number: ED22-18350-SG

Author: P.L. Andresen, D.J. Shim, T. Terachi, T. Yamada, Y. Nomura

Publication Date: 2022

A database of SCC growth rates in commercial austenitic stainless steels exposed to pressurized water reactor (PWR) primary water environments was developed and analyzed from international data in high temperature water, with an emphasis on deaerated or hydrogenated water while also including water containing oxygen. Crack growth rate (CGR) disposition equations were derived to reflect the effects of stress intensity factor (K), temperature, Vickers hardness (HV, to represent retained deformation), with enhancement factors for oxygen-containing, high corrosion potential conditions. The tolerance to chloride and sulfate impurities in PWR primary water was also evaluated.

Proposed Inclusion of UNS S82031 Into ASTM A1084

For new products there are always a need to include them in relevant standards. One of the major areas of standards are the ones verifying that the final solution annealing has been adequate not creating detrimental levels of precipitates. For duplex stainless steels the ASTM A923 and ASTM A1084 serve well for this purpose. The relatively new duplex steel UNS S82031 should be fitted in either of the two standards. It has been shown earlier that ASTM A1084, intended for leaner duplex steels, which does not precipitate intermetallic phases, fits better as these do not precipitate easily in UNS S82031. A modified, somewhat more aggressive, test solution for method C has also been evaluated and is proposed as a more relevant solution for the inclusion of UNS S82031 and possibly also other mid-range duplexes into ASTM A1084.

Proposed Standard for Levels of Inspection

Product Number: 41208-431-SG

Author: Louis G. Lyras, Dave Hatherill, William LePage

Publication Date: 2008

$20.00

This paper identifies the problems with current inspection procedures and discusses a proposed standard for levels of inspection that the owner will specify in the contract documents. The paper identifies the problems and cost to contractors and owners for inspection without clear and specified inspection standards and will demonstrate a savings without compromising the quality of the work.

Proposed Test Protocol for Evaluating Internal Coating Systems for Railcar Sour Oil Applications

Product Number: 51324-20646-SG

Author: Amal Al-Borno; Moavin Islam; Henry Pedraza

Crude oil is usually transported by pipelines from the production areas to refineries. However, in North America, particularly Canada, a significant amount of crude oil is transported via specially designed railcars. The internals of the railcars are typically coated with a high-quality coating system to prevent corrosion. Still, coating failures do occur due to the unique cyclic operating service conditions of the railcars. Thus, elevated temperatures are used to reduce fluid viscosity with a resultant increase in the vapor pressure while the loading of the oil in the railcars. Once loaded, the crude is transported under ambient temperature and pressure until the railcars reach their destination. During off-loading, elevated temperatures are again used for reducing the viscosity of the oil. After emptying the contents, the railcars are allowed to return to ambient conditions and sent back to the production area to repeat the loading, transportation, unloading cycle. Currently, there is no established test protocol to evaluate candidate coating systems for railcar internals under simulated operating conditions. Testing is usually done under a single set of operating conditions of loading or unloading and does not include the synergistic effect of the different temperature variations. This paper presents a detailed test protocol for evaluating candidate coating systems for railcar internals. The proposed test protocol was designed to simulate the expected service conditions of railcars using a modified NACE TM0185-2006 test procedure, “Evaluation of Internal Plastic Coatings for Corrosion Control of Tubular Goods by Autoclave Testing”. The modification includes the cyclic service condition of railcars – fuel loading, loaded transportation, off-loading, dry heat and empty transportation.

Protecting Steel Reinforcement by Coating Concrete with Thermal Spray Zinc

Product Number: 51324-20750-SG

Author: Bernardo Duran; Wade Campbell; Evan Stuart

Publication Date: 2024

$40.00

This paper, which serves to accompany a presentatiopn at the AMPP Annual Conference 2024, discusses the preperation and coating of coincrete with thermal spray zinc to protect the underlying steel reinforcement from corrosion on two bridges in regon. Descriptions cover the inspection, preperation, and repair of the concrete, and then follow up woth explanations on the application of the thermal zinc coating. Lastly, the presentation will summarize how the anode provided by the zinc coating protects the underlying steel reinforcement, and how it can be maintained and inspected over ites expected service life.

Protection of Concrete Floors in the Food and Beverage Industry

Product Number: 41207-371-SG

Author: Jim Ratliff

Publication Date: 2007

$20.00

While cementitious urethane technology for flooring applications has been around for quite some time now, the characteristics of these systems are not widely known by key decision makers within the food and beverage processing industry outside Europe. This presentation is intended to provide a generic and comparative analysis of cementitious urethane topping systems, as used in food and beverage processing facilities (with a particular emphasis on meat processing facilities), versus other widely used topping systems, including epoxy, polyester, vinyl ester, methylmethacrylate (MMA), polyurethane, polyurea, and tile technologies.
