PRESSURE TESTING SERVICES IN OMAN
The EIWAA Oil and Gas Services provides pressure testing services in Oman for a variety of items including manifolds, air compressors, pressure vessels and pipelines. Pressure Testing Services shall be Hydro testing services and pneumatic Testing. Pneumatic testing is done to confirm that a system can safely be operated at its maximum pressure by pushing it over the pressure limit that was intended for it. In pneumatic testing services, air or an inert gas medium like nitrogen is used. We are one of the pressure testing companies in oman for Hydro testing services, pipeline freezing services, Nitrogen services, Nitrogen purging services, pipeline freezing and pipe freezing services.
The hydro test, also known as the hydrostatic test, is a pressure test used to demonstrate the integrity of a pressure vessel using a liquid medium. Clean, fresh water or treated fluid is typically used in flushing or hydrostatic testing operations. When appropriate, a suitable corrosion inhibitor, chloride-controlled water, combination, or mixture of these is employed to guard against damage from water’s negative effects on the pressure vessel material used in its product service. A hydrostatic test involves applying pressure to a pipe or other component in order to assess its integrity. The structural integrity of pipelines and other pressure-containing infrastructure is assessed using this test. The main technique for checking for leaks and evaluating the structural soundness of boilers, meter skids, compressed gas cylinders, pipelines, tubing, and other pressurized containers is hydrostatic testing. In hydro testing services, a pressure of 1.5 times the MAWP is used for pressure vessels constructed in accordance with ASME Sec. VIII Div. I year 1999 editions or before. Any vessel built after 1999 is subject to a hydrotest pressure that is 1.3 times the maximum allowed working pressure or MAWP.

PIPE FREEZING SERVICES IN OMAN
EIWAA Oil and Gas Services is one of the leading pipe freezing companies in oman and it is the best safe and economical method of repair/maintenance of piping systems by temporarily isolating the localized area. For all types of piping modification works and maintenance services, it is not preferable to drain down systems for avoiding venting procedures. Pipe freezing services related to the hot work maintenance of storage tank terminals saves oil and not required to arrange any bulk transfer of toxic fluids and liquids. Pipe freezing services in oman allows safe maintenance works without interruption of processing systems. Procedure for Pipe Freezing Services covers fabrication of metal cover/ jackets as per the pipe size and it is installed over the pipe. Inject liquid nitrogen into the jackets by special nozzles where the temperature reaches negative (-ve) and the liquid nitrogen freezes the pipe. Pipeline freezing services may more effective of the diameter ranges from ¼” to 24” and it is not suitable if the pipe size ≥ 24” medium or elevated temperature as well as liquids with different freezing point or pipe is too small with complex geometry. Pipe material selection shall be either copper or steel and the pipes should have sufficient capacity to withstand pressure created by the ice plug.
NITROGEN SERVICES IN OMAN
EIWAA Oil and Gas Services provides complete Nitrogen services in oman by Nitrogen leak testing services, Nitrogen Purging Services at Nitrogen helium leak testing services at power plants and refineries. If you are looking for a nitrogen purging services in oman for Nitrogen filling, Nitrogen lifting and Nitrogen pressure testing services, EIWAA is your best nitrogen solutions partner to meet your complete Nitrogen services. Nitrogen purging services in oman 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 for all the major storage tank and piping terminals, using our Nitrogen filling and Purging Services to create a safe and controlled environment by removing unwanted gases. Nitrogen Purging services or N2 Purging Services in oman using for pigging, Pressure drying, pressure transfer, pipeline cleaning, decreasing oxygen in lines, maintain purity of gases & prevents explosive reactions.
Nitrogen purging is a safe method to clean and prepare oilfield pipelines by nitrogen gases. Moisture, particles, 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 oman 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 oman. N2 Purging in oman 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 at major tank terminals and power plants
- N2 Purging of transformers and volatile electrical systems in power plants and refineries.
- Pipeline drying or purging services to control oxygen concentrations especially used in pipeline Maintenance services
- Nitrogen Helium Leak Testing Services
