Case Study: Micro Welding of Pipes With Molykote

In order to understand how industrial experts were able to avoid micro-welding of pipes with a Molykote product, we will explore the context, the problem and the way it was solved.

The Client

The client for this project was a business involved in the maintenance, repair & overhaul (MRO) of the mining industry, whose work depended on rock-drilling machines.

The Problem

The rock-drilling machines used by the client drilled over 20 tons of rock. These machines required lubrication in order to prevent seizures in the threaded connections of the pipes. The pipes are subject to high loads in a moist and dusty environment, of temperatures exceeding 200°C and a speed of 1000 RPM.

Originally, the client was using a zinc-based thread compound, applied over the threaded connection, before the pipes were assembled and the drilling began. However, the client noticed wear and tear of the threaded connections, leading to the micro-welding of pipes. The lubricant used was not able to provide the correct protection to the threaded connections. The zinc-based thread compound was unable to provide the correct torque when disassembled.

The Solution

The client contacted Molykote representatives about this problem, who suggested Molykote G-N Plus Solid Lubricant Paste as a solution. Molykote Metal Assembly Paste is not a compound or a grease; it is a lubricant paste capable of supporting extreme drilling conditions due to it MoS2 and other solid lubricants, which can avoid micro-welding in applications above 400°C with a high load.

The Benefits

Molykote G-N Plus Solid Lubricant Paste provides:

  • Great protection against fretting wear and corrosion
  • Extension of the service life of components
  • Low coefficient of friction
  • Reduction of surface damage
  • Prevention of seizing, galling and excessive friction

Molykote G-N Plus Solid Lubricant Paste provides essential value to the client, helping to reduce downtime and frequency of maintenance, improve efficiency and workplace safety, and avoid micro-welding of pipes.
