Industrial Maintenance and Repair Services: Minimum Downtime, Maximum Operational Efficiency

At DRS Makina, the critical value of time in heavy industry facilities is fully recognized. Comprehensive maintenance and repair services are provided by our expert team of experienced engineers and technicians; aiming to minimize facility downtime and maximize operational efficiency. Through preventive, predictive, and planned maintenance strategies, mechanical failures in your production processes are resolved on-time, without ever compromising on quality and occupational health and safety (OHS) standards.

Key Sectors for Our Maintenance Services Professional maintenance support is provided to 4 main sectors where uninterrupted production is of vital importance, process dynamics are fully mastered, and international quality standards are strictly adhered to:

  • Power Plants: Cogeneration facilities, steam and gas turbine lines.
  • Petrochemical Plants: Critical process units operating under high pressure and temperature.
  • Chemical Plants: Corrosive and hazardous fluid systems.
  • Food & Beverage Plants: Production lines requiring high hygiene and stainless steel standards (FDA, etc.).

Our Comprehensive Activities for Maintenance Processes Mechanical maintenance operations are considered not merely as troubleshooting, but as integrated engineering projects. In this context, there are 7 fundamental activity steps managed end-to-end:

  1. Comprehensive Planning and Optimization: Execution of critical path analyses and meticulous planning of the operation schedule to reduce downtime.
  2. Strategic Spare Parts Management: Advance identification, international standard procurement, and inventory management of critical components required during maintenance.
  3. Design and Detailed Engineering Services: Execution of mechanical calculations (TEMA, ASME) and design improvements (SolidWorks/AutoCAD) for equipment requiring revision.
  4. Industrial Inspection Services: Reporting the current fatigue and corrosion status of equipment using Non-Destructive Testing (NDT – RT, UT, PT, MT) methods.
  5. Expert Workforce Provision: Support of expert foremen, welders, and installation personnel holding international welding certificates, scaled according to project density.
  6. Comprehensive Maintenance Operations On-Site or at Our Factory Workshops: 6 specific repair processes executed by our mobile field teams or at our own facilities, depending on the plant’s condition and equipment portability:
    • Shell & Tube Heat Exchangers Maintenance Services: Tube bundle extraction, leak repair, retubing, and tube expansion processes in heat exchangers.
    • Storage Tank Maintenance under API 653: Replacement of bottom, shell, and roof plates of storage tanks, leak testing, and repairs in accordance with API 653 standards.
    • Valve Maintenance and Overhaul: Dismantling of heavy industry valves (gate, globe, ball, butterfly), replacement of sealing elements, and execution of pressure tests.
    • HRSG (Heat Recovery Steam Generator) Maintenance: Repair and replacement of critical boiler systems, pressure pipes, and coils in power plants.
    • Chemical Cleaning Services: Cleaning of scale, deposits, and corrosion accumulations on the inner surfaces of process equipment using special chemicals that do not harm the system (Pickling & Passivation).
    • Sandblasting and Painting Services: Cleaning of corroded surfaces via industrial sandblasting (grit blasting) and coating with epoxy or industrial paints in compliance with specifications.
  7. Post-Maintenance Testing and Certification: Execution of hydrostatic/pneumatic leak tests after all operations, followed by the certification and handover of the system in full operational condition (Start-up).
