Restoration of Historic Architectural Tiffany Metalwork Relies on HighPerformance, Environmentally Safe Coating System for Long-Lasting Protection

Product Number: 41214-872-SG

Caretakers of outdoor monuments, sculptures and high-value architectural metalwork face formidable preservation challenges. Durable, low-maintenance coatings are needed that provide longer-lasting protection against corrosion and degradation, while being safe for the environment. We describe work done in collaboration with conservators at the Philadelphia Museum of Art, and Portland State University, to develop water-based fluoropolymer coatings that meet the critical needs of the conservation and architectural communities.

The use of Hydrogen as a fuel is widely discussed today with stainless steels able to be used for tubing and as fittings in various systems. The application areas vary from tubing and fittings in vehicles, filling stations, production or storages facilities. In all applications resistance against hydrogen embrittlement is a key prerequisite. Earlier the susceptibility to hydrogen embrittlement of three austenitic stainless steels tested by different SSRT methods has been reported: electrochemical charged, thermal pre-charged and in situ testing in 85 to 87.5 MPa hydrogen gas at -40°C. The low nickel versions of UNS S31603 experienced brittle fracture whereas the high nickel version of UNS S31603 as well as UNS S31675 had ductile fractures. The appearance of the fracture surface in SEM indicates that all test methods promote ingress of hydrogen to the center of the specimen. In this work, study of the deformation mechanisms has been performed by EBSD obtained 5 mm from the fracture. The study reveals that the low nickel version of UNS S31603 experiences formation of deformation induced martensite, the high nickel version of UNS S31603 shows no martensite but produces twinning. UNS S31675 which has a small grain size shows no formation of martensite and only small degree of twinning. The deformation structures are discussed with respect to the outcome of the SSRT-testing and austenite stability.

Resurrecting a Concrete Landmark

Product Number: 41215-896-SG

Author: Todd Gomez

Publication Date: 2015

The spray-applied, two-component, ambient-cured polyurea, which features no VOC’s and low odor, can be applied at colder temperatures than current available coatings. This wider temperature application range extends the season for restoring outdoor concrete substrates. The technology provides quick dry times; leading to faster return-to-service and helping applicators and owners meet tight deadlines.

Oilfield waters have a complex composition depending on reservoir rock at different geographical locations that can be carried into the production water¹. The alteration in environmental conditions such as pressure, temperature, salt content or pH can cause the liquid to oversaturate and the contained ions to form complexes. These will precipitate out of the solution, deposit and grow on contacting surfaces such as reservoirs, upstream production tubing, sub-surface safety valves, water injection lines to top side refining equipment namely heat exchangers and transport lines ^2–4. Scaling can also be induced by incompatible mixing of fluids. For example CaCO₃ and /or BaSO₄ form through typical mixing of SO4 2- containing sea water with the formation water that carries high concentrations of divalent cations such as Ca²⁺and Ba^2+₂. Similarly, sulfide scales form upon mixing with H₂S-containing formation water enriched with Fe, Zn or Pb ions ⁵. ZnS and PbS have been observed to form in presence of only 25 ppm H₂S at gulf of Mexico containing 50 ppm Zn and 5 ppm Pb , due to their low solubility constant K_sp ^6,7.

Retention of Pr-Construction Primers During Shipbuilding

Product Number: 41211-586-SG

Author: J. Peter Ault

Publication Date: 2011

$20.00

Pre-construction Primer (PCP) is a zinc-containing, weld-through primer applied at low thickness to minimize rusting of steel during storage and fabrication. PCP removal is perceived to reduce risk of coating failure associated with painting over an aged zinc primer. PCP is retained in many commercial shipbuilding operations in order to reduce costs and provide a better performing coating system. This paper will review commercial industry practices and the guidance provided by marine coating manufacturers.

Rethinking Sulfide Stress Cracking (SSC) Resistance Super Martensitic Stainless Steel (SMSS-13Cr) Bar Stock With 95 Ksi MY

Product Number: 51322-17614-SG

Author: Karthik Krishnan, Chad Glaesman

Publication Date: 2022

$20.00

13Cr-5Ni-2Mo type Super Martensitic stainless steels referred to as SMSS-13Cr type grades can provide good general corrosion resistance such as in high CO₂ environments combined with higher strengths and excellent toughness² making them a prospective material choice for long term downhole completion equipment depending on actual well conditions. One of the main limiting factors for the use of SMSS-13Cr type grades is the Sulfide Stress Cracking (SSC) resistance in presence of H₂S in downhole well conditions. Therefore, a good understanding of this behavior is essential to facilitate the material selection process.

Publication Date: 2018

$20.00

Cities and towns across the nation are undergoing revitalization programs at an ever-increasing pace as citizens demand better recreation facilities, more choices in housing and entertainment, and maximum benefits of economic development. But what do city planners do when their “ugly old water tower” stands right smack dab in the middle of the area to be redeveloped? Their water system needs the tank, but their constituents don’t like the looks of it…so they make it the landmark at the center of their plans!

Review and Recommendations on PWHT Exemptions for 2014 Edition of ASME B31.3

Product Number: 51320-14543-SG

Author: Deepak Mankar

Publication Date: 2020

$20.00

A major significant change in fabrication/ welding of process piping was brought out by ASME B31.3 2014 addition Table 331.1.3 “Exemptions to Mandatory Postweld Heat Treatment” It now allowed for all carbon steel conforming to P- No1material group for all control Thickness and All weld type with exemption from Postweld heat treatment if a preheat of 95°C (200°F) is applied prior to welding on any nominal material thickness >25mm (1in). Similar exemptions are provided for P-No.3, P-No 4 group 1, and P-No. Group1. These exemptions required a closer scrutiny prior to adaptation. The review is an attempt to make end users aware of its significance.

On July 28, 1986 a tornado struck an area outside of Sioux City, IA, destroying one of the four power generation plants at Port Neal. The tornado registered an F4 on the Fujita scale, indicating that “devastating damage” had taken place on the ground. Although there were no major injuries to the employees at the plant, severe damage took place on the equipment.

In late 2021, several leaks were observed inside the waste heat boiler coil of the steam reformer furnace at the refinery. The leaks were located in the first row of tubes of the hot bank in the vertically-oriented coil, where boiler water inside the tubes is heated via waste heat of the reformer stack. The waste heat boiler coil has a design duty of 69.59 MMBtu/hr (~20.4 MW), with design pressures and temperatures of 1010 psig (6.9 MPa) and 700°F (371°C), respectively.
