Treated Water Pipeline Leak Repair - Case Study

A steel mill was losing 50 to 70 gallons/minute on a 10 inch chemically treated water pipeline. Metal Repair SG 527 and the larger size Stop-It pipe wrap sealed the leak and brought the water loss to a stop.

Bag House Protection - Case Study

A coke and battery plant was having erosion and corrosion problems in their bag houses. Looking for an alternative to expensive replacement, they contacted USI to come up with a solution. The small holes were filled with 3M Scotchkote Urethane Metal Repair RG 501. The entire structure was then coated with 3M Scotchkote Epoxy Coating 152LV.

Bearing Housing Repair - Case Study

A bearing housing was very badly worn on both the inside and outside. It was repaired without being dismantled. The roller bearing was fixed in the housing. All gaps were sealed with 3M Scotchkote Urethane Metal Repair RG 501. After these were sealed, 3M Scotchkote Metal Surfacer FG 502 was injected with a cartridge between the roller bearing and the bearing housing. The bearing housing was back in service in a few hours.

Chemical Storage Tank Repair - Case Study

This chemical storage tank at a heating plant was suffering from heavy corrosion. The tank was coated with 3M Scotchkote Epoxy Primer GP 120, our anti-corrosive epoxy, then finished with 3M Scotchkote Urethane Coating UV 840, a polyurethane finish designed for long-term protection of brickwork, concrete, steel, and aluminium.

Containment Area Protection - Case Study

This concrete containment area had been earmarked for refurbishment. However, all they needed was a high performance coating that would resist acid. They first used 3M Scotchkote Epoxy Ceramic Rebuild EG 513, a metal repair compound, to rebuild metal components. Next, 3M Scotchkote Epoxy Coating 175UC, a high performance, solvent-free coating, was used to provide chemical resistance even under total immersion conditions.

Fan Impeller Refurbishment - Case Study

A carbon steel impeller on a dust extraction fan had been subjected to ''heavy wear.'' All loose material was scraped away. The surface of the impeller was degreased using 3M Scotchkote 020 Cleaner and then blasted cleaned. Our multi-purpose ceramic epoxy 3M Scotchkote Epoxy Ceramic Rebuild EG 513 was used to rebuild the deeply pitted areas prior to the application of two coats of 3M Scotchkote Epoxy Ceramic Surfacer FG 512. One coat of 3M Scotchkote Epoxy Ceramic Surfacer CR 511 was then applied.

Gate Valve Repair - Case Study

The surfaces of this gate valve had been subjected to severe erosion and corrosion as a result of the very aggressive operating conditions. All loose material was scraped away. The surfaces were then blast cleaned. Our multi-purpose ceramic epoxy 3M Scotchkote Epoxy Ceramic Rebuild EG 513 was used to rebuild the internal surfaces of the gate valve, after which 3M Scotchkote Epoxy Ceramic Surfacer CR 511 was applied.

Metal Storage Tanks - Case Study

The corrosion on these metal storage tanks was so bad that the stuctural integrity was threatened and required immediate repair. The tanks were blasted to remove corrosion and other contaminants. Uni-Tech MC Primer was applied. Then two coats of our polyurethane coating 3M Scotchkote Urethane Coating UV 840, a UV stable, high performance coating, were applied to provide long term protection.

Processing Pump Refurbishment - Case Study

Pumps at a processing company were in poor condition, effecting their efficiency. 3M Scotchkote Epoxy Ceramic Rebuild EG 513 was used to rebuild the corroded areas inside the pump. The internal surfaces of the pumps had two coats of 3M Scotchkote Epoxy Ceramic Surfacer CR 511 applied and the external surfaces were coated with two coats of 3M Scotchkote Epoxy Primer GP 120 for a like-new finish.

Pump Refurbishment - Case Study

After many years of use and being daily subjected to the elements, the cold water pumps at this coal-fired power station had been earmarked for refurbishment. The surfaces of the pump to be coated were abrasive blast cleaned prior to the application of two coats of our solvent-free ceramic epoxy coating 3M Scotchkote Epoxy Ceramic Surfacer CR 511 in contrasting colors.

Rotary Lobe Blower Refurbishment - Case Study

Process Gas Compressor rotary lobe blowers were found to be severely eroded/corroded.
The rotors were abrasive blasted. All deep areas were filled with Epoxy Metal Repair EG 503 and Epoxy Ceramic Rebuild EG 513 and leveled to provide a suitable rebuild base. One coat of Epoxy Ceramic Surfacer FG 512 was applied followed by two coats of our solvent-free, low friction epoxy coating Epoxy Ceramic Surfacer CR 511. The same procedure was carried out on the head plates, but without the Surfacer CR 511 topcoat. A final coat of Epoxy Ceramic Surfacer FG 512 was applied. The casing was rebuilt using Epoxy Metal Repair EG 503, leveled, and finished with one coat of Surfacer FG 512.

Steel Roller Stand Repair - Case Study

Metal-Tech XG, a two component, multipurpose, synthetic metal repair compound, that
bonded/secured plates to the repair gap. The gap was caused by the heavy impact, speed, and weight of steel ingots being rolled.

Ventilator Refurbishment - Case Study

The housing, impeller, and castings of this furnace exhaust gas ventilator, which was required to withstand wet air at a temperature of 248-302°F, was to be refurbished. The internal components of the exhaust gas ventilator were abrasive blast cleaned, ensuring all loose abrasive dust and debris were vacuum cleaned away. 3M Scotchkote HT Lining HTX 517 was then applied.
