The benefits of metal-free anti-seize

Government regulations are gradually persuading industry to use more sustainable anti-seize lubricants that are free of metals. Vaughan Bartleson explains the advantages of adopting metal-free lubricants and how they can reduce wear and tear on machinery.

It is common when a situation is proceeding as planned to say everything is “running like a well-oiled machine”, indicating that, even on a basic level, most people understand the importance of lubrication for moving parts in industry.

On a more specialised level, maintenance staff in relevant industries such as mining, manufacturing, power, oil and gas could describe the benefits of good quality anti-seize lubrication. These could include protection of metal parts from rust, corrosion, galling and seizing, easier assembly and disassembly, the reduction of friction and wear on critical operating equipment, plus a protective role.

What might be less understood is that not all anti-seize products are equally beneficial for the machinery they are used on, the workers applying them or the environment. The choice of lubricant can have a great impact on any operation, especially over time and with possible changes to government regulations.

Step 1. Anti-seize works by suspending solid particles in a high quality grease, which dissipates at a higher temperature. Solid particles remain.

Step 2. The remaining particles plate the surface, forming a protective finish that prevents against cold welding, galling and metal seizure.

HEAVY METAL POLLUTION

Common ingredients in many of the anti-seize lubricants used widely in industry are copper, nickel, aluminium and zinc, plus other heavy metals. The governments of Australia1 and New Zealand2 are increasingly requiring industries to act sustainably. This will see metallic contaminants being phased out, requiring industries to convert to the use of metal-free anti-seize products.

The dispersal of heavy metals, including lead, into the environment where contamination of soil and water supplies can occur is a growing concern for all types of industry. The use of anti-seize products containing these harmful substances can subvert a company’s anti-pollution initiatives, as well as potentially causing harm to workers, the public and the environment.

Using anti-seize products containing nickel and copper can be counterproductive, as they could cause corrosion when used on stainless steel, brass and bronze items, such as pipes.3

IMPURITIES AND CORROSION

Many workers incorrectly believe the same metal-based anti-seize they are familiar with can be used in every circumstance. Maintenance staff are not always properly trained in which anti-seize is appropriate for particular applications, nor why the right choice is important.4 But there is a high cost to the business for making an incorrect choice.

When incorrect metal-based anti-seize lubricants are used on machinery, causing corrosion, the parts must be replaced. This can cause unscheduled shutdowns, meaning profits are lost while machines are inactive. It further costs the industry by requiring parts to be replaced with increased frequency, thereby decreasing mean time between failures (MTBF).

Corroded and rusty machine parts are also an increased WHS risk5, as greater force needs to be applied to loosen joints, and seizing, vibration and other inefficient operating difficulties can be encountered.

METAL-FREE ANTI-SEIZE

These problems, including the need to comply with changing legislation, can be avoided by simply switching to a metal-free anti-seize lubricant.

A high quality metal-free anti-seize, such as those manufactured by Loctite, can also provide other benefits. In addition to being competitively priced, Loctite’s range of metal-free anti-seize products reduce wear and tear on machinery by using graphite, which acts more effectively to evenly lubricate than metal-based products, thus lowering maintenance costs.

Loctite’s heavy duty anti-seize is widely used in mining, quarrying and manufacturing plants, particularly in oil and gas, where copper-based anti-seize is prohibited. It has a reputation for quality and affordability and is available in both liquid and stick forms. Risks are reduced for workers, who are consequently not exposed to heavy metals, and the environment is not exposed to heavy metal pollution.

The heavy duty anti-seize functions on all metals including galvanized iron, stainless steel, brass, aluminium and soft metals between -29°C and +1315°C.6 It has been formulated to resist higher temperatures than most other anti-seize products on the market. Loctite’s heavy duty anti-seize is also non-reactive with the catalyst used in petroleum refineries; traces of copper from metal-based anti-seize products can theoretically contaminate and deactivate the catalyst used in these operations.7

Where other anti-seize products fail to perform, Loctite’s heavy duty anti-seize can continue to work, according to rigorous testing of the product. Other anti-seize products can fail to be approved for gas turbine applications, but Loctite has GE approval for this use.

The Loctite heavy duty anti-seize stick produces all the same benefits as its liquid counterpart, with the semi-solid form suited to convenient use overhead. Small enough to be kept in a pocket, it is convenient, fast and easy to apply, and it won’t leak or drip onto workers or surfaces.

When considering the need to comply with environmental sustainability policies, worker safety, machine longevity and ease of operation, plus overall effectiveness in every application, Loctite’s range of metal-free anti-seize products can fulfil all requirements, to keep any job running smoothly.
