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

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.
