PRE-COMMISSIONING ACTIVITIES (PROJECT SITES):
Combining several of GMET's specialty services and experience Manpower we are able to offer our clients a comprehensive pre-commissioning package under a single contract structure. Our engineers work closely with our clients to understand the project requirements, considering acceptance criteria and schedule to develop to most effective cleaning strategies. Selecting and combining the below listed services GMET can offer the highest quality and economical way in the shortest time at the best value. Below Activities offering during pre-commissioning project sites :
- Chemical cleaning
- Hydro milling
- Pipe line Servies
- Lube oil flushing
- Pressure testing
- Catalyst Handling
- Steam Blowing
- Waste Management
CHEMCIAL CLEANING :
GMET integrates vast experience with the most advanced of equipment to provide outstanding results. Each project is pre-engineered to consider the optimal flow paths and chemistry tailored to the particular system metallurgy and contaminants, to design the safest and most efficient cleaning process. Our team of chemists control the process from our portable site laboratories located at the project site to ensure the cleaning is optimized and the client’s equipment protected at all times.
GMET’s fleet of equipment includes truck mounted chemical circulators providing a small footprint and minimal set up time – ideal for heat exchangers. We also carry a fleet of pumps ranging from 200 gpm up to
4000gpm and storage tanks up to 80m3 capacity. Our equipment and pipework can be combined by our engineers to match up to any size system.
Performing Degreasing, Acid cleaning, Pickling, Solvent cleaning and other specialty chemical processes GMET offer the best chemical cleaning and corrosion protection solutions for heat exchangers, HRSG’s, furnaces, boilers, condensers and pipework for pre-commissioning and maintenance.
HYDRO MILLING:
GMET’s hydro milling services offer the best in pipe internal cleaning. Operating at up to 15,000psi and 70gpm the specially designed system can precisely clean large diameter pipework up to 72” negotiating multiple elbows and even vertical configurations. The rotating hose system and specially designed cleaning heads ensure that the maximum cleaning force is delivered directly to the surface with precise control. Our technicians will design the cleaning heads for your specific application, be it detailed removal of mill scale to decoking process piping.
PIPE LINE SERVIES:
As part of our commitment to offering a full range of solutions to our clients GMET has diversified into pipeline services in recent years. Maintaining our approach to safety and quality GMET can offer pneumatic testing, hydro-testing, pigging, chemical cleaning drying and nitrogen purging. Pigs are specifically designed to match the pipeline design, product to be removed and cleaning specification to be achieved. From de-cruding to pre-commissioning, including dual diameter lines, GMET are able to engineer the most efficient solution to your pipeline requirements.
LUBE OIL FLUSHING :
The high velocity pumps operate at flow rates of up to 200m3/hour to ensure the maximum turbulence and cleaning force. The self-contained skids possess on line filtration, heating and particle counters to monitor the progress to achieve the required NAS standard in the shortest time. For more complex projects our engineers can model the fluid mechanics of the system to ensure that the desired Reynolds Number is achieved in all parts of the system. For pre-commissioning purposes, the same skid can be used for chemical cleaning and pressure testing providing a one stop solution.
PRESSURE TESTING :
As part of its complete pre-commissioning package GMET can offer a full pressure testing service. GMET carry stock of a wide range of fully rated test blinds and can supply full mechanical preparations alongside the actual pressure testing services. Providing full test pack documentation, GMET’s services comply with the highest QA/QC standards from engineering through to execution. GMET provide both hydrotesting and pneumatic testing in line with international standards ensuring delivery of a safe service on equipment, vessels and pipelines.
CATALYST HANDLING :
GMETs team of skilled catalysts technicians utilize the latest equipment and technology to perform blind to blind unloading and loading services for all types of catalyst reactors from driers to hydrocrackers and tubular reformers to Ethylene Oxide Reactors. Following a rigorous training program in our own simulator, our technicians acquire the skills to perform complex and arduous activities under inert conditions using the latest in Life Support Systems.
GMETs equipment is designed to provide the maximum efficiency whilst minimizing catalyst attrition and exposure to personnel. Offering traditional sock loading methods alongside dense and uni dense loading technologies, GMET provides the full range of catalyst handling services for all situations.
STEAM BLOWING :
GMET has embraced the latest advancements in professionally engineered and executed steam blow services available internationally. Offering a fully engineered service GMETs specialists model the fluid mechanics on the latest software to ensure the most effective and safe steam blow conditions are met. GMET can provide piping design and engineering as required to match to it range of acoustic silencers and quench attemperation systems. Our expert engineers will work closely with your plant operators throughout the execution process, monitoring the success through the software modelling and remotely operated target insertors, with results available in real time on site.
Applying similar principles and fluid engineering GMET can deliver engineered air blows to the most complex systems. Modelling the flows and pressures in conjunction with its purpose build actuated valves GMET engineers can control the energy to prove the maximum velocities and cleaning forces have been imparted on all areas of the system.
