Unifuse HF40™ Erosion Resistant Overlay for Circulating Fluidized Bed Boilers – The Weldable Hardfacing
AZZ’s proprietary HF40™ overlay is a Fe-Cr-C-Zr hardfacing alloy with approximately 20% chromium (Cr) that provides exceptional resistance to erosion and wear as well as erosion/corrosion attack.
With proper consideration and understanding of how the hot-dip galvanizing process affects steel, asymmetrical designs or structures containing sections of unequal thickness can be successfully galvanized, as can fabrications where cold-working techniques (bending, hole-punching, rolling, shearing) are employed.
AZZ is at the forefront of renewable energy, with solutions to support growing investments across the grid
The shift towards renewable energy requires upgrades to the generation, transmission, and distribution of green energy. AZZ is ideally positioned to take advantage of this renewable secular growth trend.
AZZ Specialty Welding can develop code acceptable corrosion resistant overlay (CRO) repair strategy with machine applied weld deposit to upgrade metallurgies in lieu of plate replacements, sheet lining, window cut outs in the vessel, or high dilution manual weld deposits.
Let’s take a look at the galvanizing process from start to finish.
Since its inception, RIG-A-LITE’s SAF series has upheld a reputation as the industry’s leading choice for lighting industrial and hazardous environments. With the all-new HZALJ LED luminaire, we’re taking durability, performance, efficiency and installation flexibility to an even higher level.
Beginning in the early 1990’s, AZZ Specialty Welding initiated the first Structural Weld Overlay’s (SWOL) in coke drums. With aid from partners in the industry, SWOL process was developed as an engineered repair method utilizing advanced techniques in laser mapping, fatigue analysis, and field machine welded execution.
When two different metals are in contact in a corrosive environment, one of the metals experiences accelerated galvanic corrosion while the other metal remains galvanically protected.
RECHARGEMENT DE MÉTAL PAR SOUDAGE UNIFUSE™ D’AZZ SPECIALTY WELDING POUR LES CHAUDIÈRES DE PRODUCTION D’ÉLECTRICITÉ.
Avec des racines qui remontent aux années 1700, les chaudières à vapeur ont beaucoup évolué en fonction de la demande industrielle et résidentielle.
With roots dating back to the 1700’s, steam-generating boilers have evolved greatly based on industrial and residential demand. Learn how AZZ’s advanced welding technologies have kept pace.
AZZ Specialty Welding leads the way in alloying materials and innovative application methods to achieve longer life in the lower and upper furnace components exposed to the various forms of erosion & corrosion.
Com mais de 2.000 trabalhos executados globalmente com Unifuse® em fornalhas desde 2000, a AZZ WSI é líder mundial em extensão de vida de caldeiras.
It is important to understand that the chemical composition of the material being galvanized can affect coating characteristics. However, corrosion protection typically is not affected by these coating characteristic differences.
Adventure Park, located in Pigeon Forge near East Tennessee, is inspired by lumberjacks and the local logging industry. The park has many family friendly attractions like obstacle courses, competitions, a treetop free fall and rides. The Flying Ox is the world’s first cable-to-rail zip line roller coaster. At 1,000 feet long and 80 feet high, the Flying Ox dominates the landscape of Lumberjack Square.
Because of the significant deposition rates achievable with this technology, justification for repair at sea vs. dry-dock was clear.
Para este cliente, AZZ WSI evaluó el estado de la embarcación y definió que, realizando adaptaciones en los sistemas propietarios de soldadura automática, se podría trabajar desde el interior del casco del FPSO, en sitio, depositando capas de soldadura metálica para restaurar el espesor requerido por el diseño de la embarcación.
Para este cliente, AZZ WSI avaliou a condição do navio e definiu que realizando adaptações em um dos sistemas proprietários de solda automáticas, ele poderia ser habilitado para trabalho pelo lado de dentro do costado do FPSO, no mar, depositando camadas de solda metálica para restaurar a espessura requerida de projeto da embarcação.
TECHNOLOGIE UNIFUSE™ AZZ WSI POUR L’EXTENSION DE LA DURÉE DE VIE DES CONDUITES DE FOURS A ARC ÉLECTRIQUES (EAF)
Avant les années 1970, la technologie des fours à arc électrique (EAF) consistait principalement en des systèmes de gaz résiduels qui n’étaient pas refroidis à l’eau, mais plutôt conçus avec des plaques d’acier à revêtement réfractaire.
AZZ’s Hot-PulseTM GTAW process delivers superior weld quality, increased productivity rates and reduced risk to personnel versus conventional welding methods.
Livestock trailers are necessary in the agriculture and livestock industry. They are used daily to transport animals and can suffer considerable damage from overuse and harsh elements if not properly protected.
Any form of cold-working reduces steel’s ductility. Operations such as punching holes, notching, producing fillets of small radii, shearing, or sharp bending may lead to strain-age embrittlement of susceptible steels.

Corrosion protection begins at the drawing board, and regardless of what protection system is specified, it must be factored into the products design.
Los digestores batch con revestimientos de acero inoxidable experimentan tasas de corrosión altas lo que requiere sustitución prematura del equipo. La solución es el proceso patentado para extensión de vida del digestor ofrecido por AZZ WSI do Brasil Ltda. Esta tecnología se a implementado en mas de 300 digestores mundialmente con gran exiito.
