Where there is metal, there is corrosion. It is a fact of life, in manufacturing and maintenance repair and operations, across industries. Rust, corrosion, seized or frozen fasteners come with the territory when working with moving metal parts.
Situations naturally differ by industry. For example, high temperatures in oil refineries contribute to corrosion. Pumps and valves are the backbone of a refinery, moving the product from supply to crackers to storage. To maintain pumps and valves or replace them means removing corroded nuts and bolts.
Operations and Maintenance are difficult at utility companies, where parts become corroded due to hot and corrosive environments. Jobs come in all sizes – from a small job, like trying to get the rusty nuts off a tank access hatch, or something big like opening flanges on an intake water main pump.
High pressure and high-temperature environments in aviation vessels, such as planes and helicopters, can cause aviation parts to seize. Aviation technicians cannot afford to strip the threads on a fuel nozzle on an engine rebuild or waste time on stuck hatch bolts.
Agriculture equipment and machinery need regular maintenance to be able to plant, grow, tend, harvest, sort, pick, and pack. Whether replacing a flat on a tractor or doing an engine overhaul, there will be nuts that just won’t budge. Salvaging equipment is more cost-effective than replacing equipment.
A cooling system is down. Heating, ventilation, and air conditioning (HVAC) maintenance know the water pump needs to be changed out but find the isolation valve handle won’t budge.
Brute strength alone can make it near impossible to loosen rusted nuts, bolts, and fasteners. How best to conquer this on-the-job challenge? The most dependable solution is industrial penetrating oil. It is designed to saturate narrow spaces between two parts due to its low viscosity and surface tension.
Penetrating oil seeps into threads and crevices, loosening tight nuts and bolts. The penetrant leaves a residual film which can easily be wiped away with a cloth or wipe. It is important to understand the qualities of the penetrant to be sure it can get the job done.
“Superior penetrants get into hard-to-reach cracks and tiny spaces, helping users solve problems more efficiently,” said Sevan Demirdogen, CEO – Kano Laboratories, producer of Kroil Original Penetrant and Kroil Penetrant with Silicone.
Some penetrants include additives to improve the performance of the penetrating oil.
“Many top industrial penetrants have additives in their formula to increase the longevity of the lubrication effect,” said Demirdogen
The most common additives are:
- Extreme Pressure (EP) Additives – designed to improve wear resistance and lubricate metal surfaces. By eliminating metal-to-metal contact, the coating prevents seizure, sticking, or surface adhesion. These additives work well in high-load applications where other lubricants fail.
- Corrosion Inhibitors – used to control or eliminate corrosion. Ideal inhibitors will produce the desired effect when present in low concentrations.
- Micro Dispersants – used to envelop solid and liquid particles. The dispersant typically provides lubrication after the solvent or other carrier evaporates.
“Kroil users tell us it’s like having an extra pair of hands to help,” according to Demirdogen. “Penetrants, like ours, are fast-acting which saves time and money by reducing equipment downtime.”
