TUBES ET PANNEAUX UNIFUSE™ AZZ SPECIALTY WELDING POUR LES CHAUDIÈRES DE RÉCUPÉRATION DE LIQUEUR NOIRE (BLRB)
Le procédé de fabrication de réduction en pâte kraft a été breveté en 1884 et constitue la forme la plus courante de réduction en pâte chimique, représentant 80 % de l’ensemble de l’industrie de la réduction en pâte chimique. [1] La viabilité économique de l’ensemble du procédé ne serait pas possible sans la chaudière de récupération de liqueur noire (BLRB) utilisée pour récupérer les produits chimiques utilisés lors de la réduction en pâte déchargés depuis des digesteurs à travers une série d’évaporateurs pour augmenter leur concentration
Design Considerations for Galvanizing: Fasteners, Bolts and Nails
Perhaps the most critical choice made in the design of connections is how to protect the fasteners from corrosion. Hot-dip galvanizing delivers long-term, maintenance-free corrosion protection in a variety of exposure conditions.
Small Bore In Situ Nozzle Repairs During Pressure Equipment Turnarounds
Whether the nozzles needs to be repaired emergently or replaced in a planned turnaround, AZZ Specialty Welding has unparalleled innovative leadership in weld metal overlay technology backed by proven results.
Galvanizing Applications: Fencing
Fences are a staple in many aspects of society and particularly in agriculture, where they’re tasked with the protection of livestock and vulnerable crops or equipment. However, they’re not invincible. Wood rots, steel rusts, and stone cracks.
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.
Design Considerations for Galvanizing: Distortion and Warping
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.
Mitigating Atmospheric Distillation Unit Corrosion through Machine Insitu Methods
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.
How Hot-Dip Galvanizing Works
Let’s take a look at the galvanizing process from start to finish.
Introducing the HZALJ LED: Get to know the latest addition to AZZ’s LED Lineup
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.
Delayed Coking Unit (DCU) Process, Thermal Cycling and Bulge Mitigation Techniques
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.
Design Considerations for Galvanizing: Dissimilar Metals in Contact
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.

Design Considerations for Hot-Dip Galvanizing: Dissimilar Steel Chemistries
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.
AGA Awards: The Flying Ox
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.
AZZ Specialty Welding’s Unifuse™ Automated Weld Build-Up Process in FPSO Repairs
Because of the significant deposition rates achievable with this technology, justification for repair at sea vs. dry-dock was clear.
Primer Proyecto Para Reconstrucción de Cascos en Buque FPSO
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.
Processo de Soldagem de Reconstrução Automatizada (Build-Up) para restauração de costados de FPSOs
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.
