They protect the faculty and students from weather and traffic, and are utilized 24 hours daily. Several of the hallways are enclosed and others are partially exposed to weather.

Treasure Island Casino, Las Vegas

A facility in Las Vegas, Nevada was having a corrosion problem in its man-made lagoon. A system of rail tracks used to move full sized replicas of mast ships within the lagoon were experiencing accelerated corrosion due to electrolysis.

Dialysis Flow Meters

Attached are pictures of the flow Meter components used by a major Healthcare company with an ARCOR designed and manufactured product and process (R-7).

Cast Iron Waterbox Repair

Eight Cast Iron Waterboxes that were subject to salt water cooling were experiencing thinning and leaking. Want to know how ARCOR fixed the problem?

Heat Exchanger Channel Head Repair

A Cast Iron Heat Exchanger channel head exposed to salt water had severe metal loss on the divider plate adjacent to the tubesheet, resulting in cooling water beginning to bypass the divider plate, resulting in a efficiency drop in the unit. Want to know how ARCOR fixed the problem?

Cooling Tower Bypass

Cooling Tower Bypass Pipe was experiencing two problems; The interior of the carbon steel pipe was suffering corrosive attack from brackish salt water, and the exterior of the pipe was subject to salt spray as water exited the cooling tower, which corroded the pipe. Want to know how ARCOR fixed the problem?

Concrete Flooring

A Concrete Floor in demineralized water took up an area suffering attack from acids and caustic solutions. Splash and spill from equipment attacked the concrete leaving exposed aggregate. Want to know how ARCOR fixed the problem?

Secondary Containment

A Concrete Secondary Containment area for liquid Cyanide was in need of repair due to splash and spill erosion. Seams in the concrete required attention as well as the joint between the floor and the walls. Want to know how ARCOR fixed the problem?

Divider Plate Repair

A Cast Iron Waterbox Divider Plate was subject to salt water, and developed a through-wall penetration and the area around this hole was severely thinned. Want to know how ARCOR fixed the problem?

Waterbox Divider Plate Gasket

The gasket that seals the Waterbox Divider Plate to the tubesheet blew out, causing cooling water to erode the carbon steel divider plate. Want to know how ARCOR fixed the problem?

Water Pump Repair

This 14-foot diameter pump with a flow rate of approximately 280,000 gallons per minute was experiencing erosion and cavitation which rendered the pump inefficient. After making an attempt to repair the pump, pump efficiency still fell below the original specification. It was decided to rebuild the pump casing back to manufacturer’s specifications. Want to know how ARCOR fixed the problem?

Cast Iron Water Pump Repair

A Cast Iron Main Condenser Circulating Water Pump in salt water service was suffering the normal effects of corrosion and wall-thinning. In places, graphitization had built up to an inch in thickness and pitting was as deep as 1/2-inch. Want to know how ARCOR fixed the problem?

Rotary Vacuum Filter

This Rotary Vacuum Filter was being overhauled for a manufacturing facility in South America and needed to be coated to stop aggressive chemical attack. Want to know how ARCOR fixed the problem?

Concrete and Stainless Steel

This Coal-fired Power Plant stores large amounts of coal in silos that feed the pulverizers. These concrete silos are 30 feet in diameter and 50 feet high and sit on top of a large stainless steel funnel. When damp coal is loaded into the silo, a corrosion cell is formed that attacked the mounting structure on the interface between the concrete and the stainless steel. Want to know how ARCOR fixed the problem?

Main Condenser Repair

This Nuclear Power Plant had problems with leaking tubes caused by erosion and general leaking from the condenser at the tube-to-tubesheet joint. The outlet sheets were also getting severe scaling of 3-5 millimeters per year. Want to know how ARCOR fixed the problem?

FGD Duct

High incidents of chemical attack and particulate abrasion in WFC and Outlet Ducts of unit 3 and 4 scrubbers resulted in rapid metal loss. Want to know how ARCOR fixed the problem?

Hazardous Waste Storage

A new concrete floor in a hazardous waste storage area needed protection from a wide range of chemicals. Want to know how ARCOR fixed the problem?

Concrete Drain Trench

A Concrete Drain Trench in demineralized water takes up an area that was severely attacked by hot acids and caustics. Want to know how ARCOR fixed the problem?

Concrete Naturalization Basin

A series of three Neutralization Basins with interconnecting walls developed cracks and the expansion joint caulking system was failing. Want to know how ARCOR fixed the problem?

Liquor Tank Coating

The Liquor Tank needed to be restored due to severe metal loss caused by corrosion. Surfaces were White Metal-blasted to remove all pitted corrosion. Want to know how ARCOR fixed the problem?

Concrete Aggregate Feed Screw

Concrete aggregate feed screw veins were badly eroded from wear and needed to be rebuilt. Want to know how ARCOR fixed the problem?

Paper Mill Selectifier Screen Rebuild

Selection screen, after many years of service, suffered severe corrosion. Want to know how ARCOR fixed the problem?

Waterbox Rubber Lining Repair

Temperature probes were added to the waterbox after rubber lining system was installed. Want to know how ARCOR fixed the problem?

Deairator Tank Repair

After many years of service, a Deairator tank needed to be restored due to severe metal loss caused by corrosion. Want to know how ARCOR fixed the problem?

Mixing Propeller Repair

Hydro-Wheel Repair

Cast Hydro-Wheel attacked by erosion corrosion and cavitation. Want to know how ARCOR fixed the problem?

Circulating Water Pipe

Factory specified ARCOR™ coating system for newly fabricated circulating water system pipes. Want to know how ARCOR completed this job?

Channel Head Coating

Carbon Steel Heat Exchanger channel heads exposed to salt water developed pitting over the years to a point where metal loss became a concern. Want to know how ARCOR fixed the problem?

Waterbox Restoration

ARCOR™ protective coating system was installed at the manufacturer’s facility. Waterbox was new and specified ARCOR™ coatings prior to being put in service. Want to know how ARCOR completed the job?

Cast Iron Intake Valve Restoration

Cast Iron Salt Water intake valve body badly eroded and corroded after years of of service. Want to know how ARCOR fixed the problem?
