Case Study: Successful Implementation of MT-321 Drill Pipe Coating

Project Overview: 

Master’s Touch Global conducted a pilot project to evaluate the durability and effectiveness of the MT-321 drill pipe coating in the oil and gas industry. The primary objective was to assess the coating’s ability to prevent oxidation, corrosion, wear, and aggregate deposit mitigation while maintaining hydraulic efficiency.


The oil and gas industry faces harsh conditions, leading to premature equipment failures and costly maintenance. Traditional coatings like polyurea and epoxy have limitations, including susceptibility to damage and high maintenance costs.


MT-321, a high-temperature insulator, was applied to drill pipes. This coating is known for its:

  • High-temperature resistance (up to 800°C)
  • Covalent bonding to the substrate
  • 9H hardness rating
  • Hydrophobic and oleophobic properties
  • Resistance to chemicals, H2S, and SOx


The MT-321 coating was applied to both the interior and exterior of the drill pipes. The application process included:

  • Internal sandblasting to remove existing coatings and achieve a suitable surface profile
  • Cleaning the pipe interiors and applying the MT-321 coating with an internal coating machine
  • External sandblasting and coating with an airless spray gun

Locations: This project was implemented in several regions, including the Gulf Coast Countries (GCC), where drill pipes frequently require interior resurfacing due to harsh conditions.


After 16 months of continuous use in various drilling conditions, the MT-321 coated pipes demonstrated outstanding performance:

  • No rust or corrosion observed
  • Coating remained intact without sloughing or peeling
  • Simplified debris removal due to the non-stick finish
  • No impact on drilling operations


The pilot project confirmed that MT-321 significantly enhances the durability and efficiency of drill pipes. By reducing maintenance costs and extending equipment lifespan, MT-321 proves to be an excellent addition to the oil and gas industry globally.


  • Reduced maintenance and replacement costs
  • Improved operational efficiency
  • Enhanced safety and longevity of equipment

Recommendation: Based on these results, we recommend adopting MT-321 for all future drill pipe coatings to maximize performance and cost savings.
