PRESSURE TESTING SERVICES IN UAE
EIWAA Oil and Gas Services is a 3rd Party Inspection and certification services for Hydro Testing Services, Pipeline Testing and Pressure Testing Service in UAE,Dubai and Abudhabi. We are one of the pressure testing companies in UAE for Hydro testing services, pipeline freezing services, Nitrogen services, Nitrogen purging services, pipeline freezing and pipe freezing services. EIWAA offers pressure testing of pipelines, Vessels, Elbows, Hoses, Cargo Hoses, Pipelines, Pipe spools, Control Valves, Actuators, Oil Suction Hoses, Water Hoses, Skids, Pressure Vessel, Manifolds, Air compressors, etc. Pipe spools and chambers either by using water (Hydro Testing) or by Air (Pneumatic Test). Our non-destructive testing services, welding inspection, painting inspection, pipeline pressure and hydro testing, pipeline integrity, and other services are all included in our third-party inspection services in UAE.
A Pressure test conducted to prove the integrity of pressure vessel with the use of liquid medium is known as Hydro test or hydrostatic test. The fluid used in the flushing or hydrostatic testing operation which is normally clean /fresh water or treated fluid. (Where applicable a suitable corrosion inhibitor, chloride-controlled water, combination, or mixture of such are used to prevent the possibility of damage due to the adverse effect of water on the pressure vessel material of its product service). Pressure Test carried out to prove the integrity of pressure vessel, nozzle, Chamber, reinforcement pads etc. with the use of dry compressed air or inert gas and water / soap solution is called Pneumatic Test. Hydro testing services are required to employ a test pressure 1.5 times higher than the design pressure or to take both the design and test temperatures into account. Two pressure gauges, along with chart recorders, are used to monitor and indicate the pressure ranges. Pressure gauges should be hydro tested using a separate nozzle from the hydrotest pump at the top of the vessel. The safety inspections performed by the Hydrotest also check for obstruction points, adequate gaskets, nuts, and stud bolts.
PIPE FREEZING SERVICES IN UAE
EIWAA Oil and Gas Services is one of the leading pipe freezing companies in UAE and it is the best safe and economical method of repair/maintenance of piping systems by temporarily isolating the specific area. For all types of piping modification works and maintenance, not prefer to drain down systems for avoiding time consuming venting procedures. Pipe freezing services in Storage tank terminals saves oil and not required to arrange any bulk transfer or storage of toxic fluids and liquids. Pipe freezing services in UAE allows safe maintenance works without interruption of processing systems. Typical pipe content may water, acid, fuel oil, paints and coolants. Procedure for Pipe Freezing Services covers fabrication of metal jackets as per the product pipe size and it is installed over the pipe. Insert liquid nitrogen into the jackets by specially made nozzles where the temperature reaches negative (-ve) and the liquid nitrogen freezes the pipe.
Necessary alternations/modifications can be performed on the pipe without liquid draining. Pipe freezing services may more effective of the diameter ranges from ¼ “ to 24 “. Pipe freezing may not suitable if the pipe size more than 24” medium or elevated temperature as well as liquids with different freezing point or pipe is too small with complex geometry. Pipe selection shall be either copper or steel and the pipes shall have enough capacity to withstand pressure created by the ice plug.
NITROGEN SERVICES IN UAE
EIWAA Oil and Gas Services provides complete Nitrogen services in UAE by Nitrogen leak testing services, Nitrogen Purging Services at Nitrogen helium leak testing services at major power plants and refineries. If you are looking for a nitrogen purging services in UAE for Nitrogen filling, Nitrogen lifting and Nitrogen pressure testing services, EIWAA is your Nitrogen solutions to meet your complete Nitrogen services. Nitrogen purging services is used for the replacement of a hazardous atmosphere with an inert dry atmosphere at power plants and oil/gas field. Nitrogen purging may either displacement or dilution and all the major storage tank terminals in UAE, using our Nitrogen filling and Purging Services to create a safe and controlled environment by removing unwanted gases. Nitrogen Purging services in UAE or N2 Purging Services using for pigging, Pressure drying, pressure transfer, pipeline cleaning, decreasing oxygen in lines, maintain purity of gases & prevents explosive reactions.
Nitrogen purging is a technique to clean and prepare oilfield pipelines by nitrogen gases. Moisture, contaminants and other foreign impurities are removed by nitrogen filling services, and it improves the remaining life assessment period of equipment’s and pipeline. Our Nitrogen pressure testing services in UAE helps to identify potential leaks or weakness to ensure integrity or performance. Nitrogen pressure testing services are widely used in Major power plants, pipelines, vessels and other pressure containing equipment’s of UAE. N2 Purging in UAE using Nitrogen as Inert gas meaning it does not react with other gases. Some main applications of Nitrogen Flushing is as follows,
- Nitrogen Blanketing services for ships and vessels at major ports.
- N2 Purging Services for transformers and volatile electrical systems in power plants and refineries.
- Pipeline drying and purging services to control oxygen concentrations especially used in pipeline Maintenance services
- Nitrogen Helium Leak Testing Services
AIR LEAK TESTING SERVICES
- Hydro Test
- Pneumatic Test
EIWAA always uses calibrated pressure gauges, chart recorders, and temperature/pressure test recorders in accordance with the specifications of the ASME/API Code. API 570 Standards require the use of ultrasonic thickness gauging for pipeline inspection services in order to conduct corrosion surveys and pipeline remaining life assessments. According to API 650/API 653; Fit to Use Evaluation of Storage tank inspection and pipeline testing is related to each other for the majority of oil and gas services. Hydro Testing Service in UAE covers the scope of NDT Testing and deflection dimensional measurements of pipeline and piping pressure testing & certification.
FREQUENTLY ASKED QUESTIONS
Pressure temperature chart is a permanent record of pressure test and piping inspection services. As a civil defense approved company, third party certification of storage tank and piping shall be performed by hydro testing and pressure testing, NDT Inspection of Magnetic Particle Testing, Ultrasonic Testing and Penetrant Testing.
To mark off the areas for the hydro test, use tigger tape and caution signs. The parts of a system should never be hydro tested against a closed valve. While the hydro test pressure is being built, maintain a minimum distance of 3 meters (m) between the vessel and any additional fittings (flanges, couplings).Consider using a suitable wetting agent when hydro testing large vessels to eliminate surface tension and air pockets .Build up the hydro test pressure gradually so that the piping has time to equalize tensions prior to the hydro test.
Radiography Test or Ultrasonic Testing is the best NDT Method prior to use pressure test.
