  • How Doxsteel Fasteners Resist Refinery Corrosion

    August 23rd, 2018

    Regardless of the application, corrosion is a constant enemy to bolting operations. When oxide accumulates in the thread engagement between a stud, nut, and equipment, the only way to free the fastener is through exotic removal processes such as metal disinteg... READ MORE >>

  • After Blue Bolts: Exploring the Latest in Refinery Bolting Technology

    August 23rd, 2018

    For decades, the leading coating system in refineries and power generation facilities has been Polytetrafluoroethylene (PTFE). PTFE gained prominence in the early 20th century under the name Teflon where it was used to coat everything from non-stick cook... READ MORE >>

  • Doxsteel Complies with the RoHS Directive

    August 22nd, 2018

    In any operational setting, facilities must take stock of their environmental impact. Whether handling sour water systems at a petrochemical refinery or installing bolts at the bottom of the ocean, care for the industry’s effects on natural ecosystems is k... READ MORE >>

  • Reducing Hydrogen Embrittlement Risk of Steel Bolting in Seawater Environment with Nickel-Cobalt Electroplating

    June 25th, 2018

    Among the several threats to bolting in marine environments, hydrogen embrittlement is one of the most dreaded. A form of environmentally assisted cracking (EAC), hydrogen embrittlement occurs when hydrogen penetrates a fastener’s base material, making i... READ MORE >>

  • Nickel-Cobalt Alloy Coating Protects Steel Fasteners from Hydrogen Embrittlement

    June 14th, 2018

    At the beginning of the year, Kathy Riggs Larsen of Materials Performance spoke with Doxsteel Corrosion specialists Omar Rosas and Oscar Garcia about the dangers of hydrogen embrittlement. A form of stress corrosion cracking (SCC), hydrogen embrittlement occur... READ MORE >>

  • How ASTM B994 Bolting Eliminates the Need for Metal Disintegration

    May 30th, 2018

    When fasteners seize, facilities require costly and time-consuming processes to free and replace them. Turnaround operations that are executed in days on unseized bolts end up taking weeks when replacing seized fasteners, leading to facility downtime that can ... READ MORE >>

  • How to Protect Your Bolts from High Temperature Environments and Liquid Metal Embrittlement

    May 30th, 2018

    Liquid metal embrittlement occurs when extreme high temperatures bring fastener coatings to their melting point. As the coating liquifies, it induces a loss in the bolt’s tensile ductility, causing it to become brittle and highly susceptible to fracture. Fas... READ MORE >>

  • We’re In: Why the Major Oil & Gas Companies are Adding New Bolting Vendors for the First Time in 20 Years

    April 12th, 2018

    In the past 20 years, no major companies in the oil & gas industry have added new bolting specifications to their Approved Manufacturer Listings (AML). Companies like Shell, Chevron, MRC Global, Anadarko, BHP Billiton, BASF, and Chemours have installed and rep... READ MORE >>

  • The Dangers of Hot Bolting

    David Dunning is a Cornell University professor who is perhaps most famous for a paper he co-wrote about ignorance and over-confidence.

    The Dunning-Kruger effect refers to people who are novice or ignorant to things they do not know but believe they are expert
