With our expert engineering team, all minor and major overhaul operations are executed with technical precision, minimal downtime, and maximum service life.
An overhaul, or major maintenance, is a comprehensive process in which all components of an industrial structure or equipment are thoroughly inspected, refurbished, and optimized.
The goal of an overhaul is not only to fix existing malfunctions, but also to extend service life, reduce operational risks, and restore the equipment or structure to its optimal performance condition.
Imagine a small defect in your machinery or structure causing the entire production line to shut down—or even triggering a costly accident!
A single failure can result in massive financial and reputational losses.
A precise and well-executed overhaul acts as a strong insurance policy that:
👉 Choosing overhaul is the smart decision of managers who truly invest in the future of their business.
Rabin Sazeh Pardaz Company, with a solid track record in industrial design, fabrication, and inspection, is recognized today as one of the leading providers of overhaul services in Iran.
Utilizing a team of highly skilled specialists and advanced equipment, we perform professional and fully-engineered overhaul operations across various industries — including petrochemical plants, refineries, power stations, production lines, cranes, diesel generators, compressors, transformers, and boilers.
Our mission is to extend equipment life, minimize emergency repair costs, and enhance overall production efficiency.
Comprehensive overhaul and major maintenance services for pelletizing units, sponge iron plants, smelting and casting sections, and related steel production facilities.
Rehabilitation, strengthening, and replacement of worn-out steel structure components to improve durability and safety.
Major maintenance operations covering all factory systems—including equipment, structures, and utilities—to restore full productivity and operational integrity.
Complete inspection and repair of production lines to increase capacity, minimize downtime, and improve operational efficiency.
Inspection, replacement, and upgrade of critical refinery and petrochemical equipment to reduce risk, prevent incidents, and increase production capacity.
Major mechanical and electrical maintenance of power generation plants to ensure safe, stable, and efficient energy production.
Renovation of electrical, ventilation, and piping systems to enhance performance and reduce energy consumption.
Repair and refurbishment of heavy machinery, pumps, and process equipment to restore maximum operational efficiency and reliability.
Inspection, calibration, and replacement of worn components in industrial and workshop cranes to enhance safety and load-handling precision.
Major maintenance and refurbishment of melting and induction furnaces, ladles, and casting machines to optimize metallurgical performance.
Comprehensive service and replacement of worn components to ensure reliable emergency power supply under critical conditions.
Refurbishment, testing, and performance enhancement of industrial transformers to minimize energy losses and improve power system efficiency.
Comprehensive cleaning, servicing, and replacement of boiler components to improve thermal efficiency and prevent risks from corrosion or scaling.
Complete repair and calibration of industrial compressors to maintain consistent operating pressure and prevent production line disruptions.
Comprehensive examination of all components using precise Non-Destructive Testing (NDT) methods to identify even the smallest defects.
A detailed plan is developed based on project requirements, including scheduling, repair scope, and resource allocation.
Worn-out components are repaired or replaced, and the overall system structure is optimized for maximum performance.
Final NDT tests are performed after overhaul completion to verify repair quality and ensure reliable equipment operation.
The project is handed over with a comprehensive report detailing all performed actions and an official quality assurance certificate.
Routine maintenance addresses existing faults, while an overhaul is a complete and comprehensive restoration that returns equipment to its original operational condition.
Depending on equipment type, usage intensity, and environmental conditions, an overhaul is typically recommended every 1–2 years.
In most cases, a temporary shutdown is required, but with precise scheduling, downtime can be minimized significantly.
Costs are determined based on equipment type, damage level, scope of work, and required part replacements. A detailed estimate is provided after initial inspection.
Yes. All overhaul services include final NDT testing and an official Quality Assurance Certificate.
Yes. Upon completion of each inspection, a comprehensive and documented report is issued in compliance with international standards (such as ASME, AWS, and ISO), enabling clients to make informed and confident decisions.
