Maviro Pre-Commissioning Services

Maviro provides comprehensive pre-commissioning services for plant start-ups, revamps, debottlenecking, and new construction. Our team has the industry’s leading products and technologies and works to develop effective and measurable customized  cleaning solutions..

We provide many types of pre-commissioning services, including:

  • Chemical cleaning
  • Engineering and project management
  • Hydrolazing and pressure washing
  • Ultra-high-pressure cleaning/cutting (UHP)
  • Hydrostatic testing
  • On-site lab analysis
  • Steam blows
  • Filtration
  • Pigging and line flushing
  • Wet and dry vacuuming

Our Process

Chemical Cleaning

Chemical cleaning is a complex process requiring  significant engineering input to safely and effectively execute the cleaning service. We evaluate the entire system to be cleaned by utilizing all design inputs, such as process and instrumentation diagrams, piping isometrics, vendor drawings and data sheets, metallurgy, and target contamination levels—reviewing and incorporating all client, owner, and vendor specifications into the engineered procedure. Then, we perform fluid modeling to confirm design flow rates and achieve the target flow velocities by selecting  the  proper temporary equipment sizing and ratings.

Maviro has the expertise and specialized equipment that are critical to turn-key chemical cleaning solutions. We can also manage third-party equipment and services such as waste disposal, waste holding tanks, waste profiling, temporary steam generators (boilers), licensed boiler operators, and water demineralizers, all of which are part of Maviro’s turn-key chemical cleaning solutions.


Our hydrolazing service is an advanced, high-pressure water jetting process that effectively cleans piping systems of mill-scale, construction debris, and process deposits. In addition, we can  clean other critical plant components contaminated with water or process deposits.

The process involves feeding a high-pressure rotating hose through an advancing device, which controls the feed rate necessary to perform the required cleaning. A specially-designed, high-pressure nozzle performs the cleaning and moves debris out of the cleaned system.

Used in conjunction with other Maviro pre-commissioning cleaning services, hydrolazing helps reduce the overall cleaning time and expense. To further maintain the integrity of the customer's system and ensure it is ready for start-up, we dry the cleaned systems and apply corrosion inhibitors.

Steam Blows

Maviro utilizes specialized silencers that reduce noise and increase efficiency, while reducing water discharge. Our team ensures that system piping is modeled and analyzed for proper velocities, pressures, and disturbance factors.  

Our services are proven to remove mill scale and construction debris from newly-installed piping systems to ensure cleanliness target values are achieved, thereby extending equipment life and providing the desired results.

Pigging and Line Flushing

Our OQ Certified pipeline professionals are industry leaders in their field, trained and equipped to handle all abnormal conditions. We can utilize vacuum operations, air-driven pump operations, and nitrogen purging, as well as our proven truck-mounted, all-inclusive pumping rigs designed by our in-house experts. We provide launchers and receivers, as well as any valves and piping that may be required.

We use cutting-edge technology in conjunction with a wide range of pigs, including different materials (foam, steel, plastic, polyurethane), shapes (bullet, flat, elongated, round), and added advanced features (scrapers, brushes, tips, cameras)to meet our customer's specific needs. We also manufacture our own line of bi-directional urethane decoking pigs at our facility in Texas. In addition, we provide hydro excavation for underground piping and other  applications to complete our full-service offerings.

Project Management
The Maviro Project Management Team ensures that field safety and service supervisors work with customer representatives to provide the safe step-by-step execution of the project tasks. Our project managers are responsible for  all correspondence with Maviro clientele. The team focuses on safety, increasing quality, reducing  delivery costs, and delivering project results on schedule—utilizing specific KPIs, templates, and predictable  patterns to achieve the most efficient and effective processes throughout the management cycle.
On-Site Lab Analysis

Maviro’s on-site analytical services provide customers peace of mind and valuable information with respect to job progress—a must for successful completion of any project.

Conducted by Maviro's QC Technicians and Chemists, our on-site analytical testing methods include:

  • Testing for various metals, accomplished by atomic absorption (mobile lab only), colorimetric analysis and or wet lab chemistry.  
  • Various processes to determine solvent concentrations, such as: % HCl, % Sulfuric, % Citric, % Ammonia, % Caustic and many other acids and bases.
  • ICOR™ (Maviro's EDTA chelation technology), monitored in our state-of-the art mobile laboratories. During the ICOR™ cleaning process, Maviro's typically will monitor: pH, temperature, residual EDTA, and % iron, % copper, solvent potential (EMF), oxidant rate, and total oxidant as needed over the course of the cleaning.
We provide a wide range of fluid filtration services in conjunction with our high-volume flushing processes. Water/oil flushing services include particle count testing to meet ISO and NAS class specifications, as well as removal of water from oil-containing systems via vacuum dehydration or other methods of phase separation. We service various systems, including, but limited to, lube oil, hydraulic, turbine lube oil, and heating systems. We also offer bag filtration, coalescing filters, filter press units, and more.
