PRESSURE TESTING IN SAUDI ARABIA
EIWAA Marine Services offers Pressure Testing Services of both Hydro testing as well as Pneumatic Testing Services for Cargo hoses and Pipelines. Hydro Testing Services covers the scope of Pipelines, vessels, elbows, control valves, actuators, oil suction hoses, firehoses, skids, pressure vessels, manifolds, air compressors etc. Our Oil and Gas Services Division provides Hydro Testing and Pressure Testing Services for pipeline and piping inspection and storage tank inspection with third-party Certification across Saudi Arabia.
The term “hydro test” or “hydrostatic test” refers to a pressure test used to demonstrate the integrity of a pressure vessel using a liquid medium. Hydro testing services must use a test pressure that is 1.5 times the design pressure or that considers the design and test temperatures. The pressure ranges are monitored and indicated using two pressure gauges and chart recorders. The best place for hydrotesting pressure gauges is at the top of the vessel with a separate nozzle from the hydrotest pump. According to the requirements of the ASME/API Code, EIWAA Marine Services always employs calibrated pressure gauges, chart recorders, and temperature/pressure test recorders. We are one of the pressure testing companies in Saudi Arabia for Hydro testing services, pipeline freezing services, Nitrogen services, Nitrogen purging services, pipeline freezing services and pipe freezing services.
PIPE FREEZING SERVICES IN SAUDI ARABIA
We are one of the pressure testing companies in saudi arabia for Pressure Testing Services, Hydro testing services, pipeline freezing services, hydro testing services, pipeline feezing services and pipe freezing services.EIWAA Oil and Gas Services is one of the leading pipe freezing companies in Saudi Arabia and it is the best economical, safe and non-intrusive method of repair/maintenance of piping systems by temporarily isolating the piping systems. By providing pipe freezing services, all types of piping modification works and maintenance, no need to drain down systems for avoiding time consuming venting procedures. Pipe freezing services in Storage tank terminals saves oil and no need to arrange any bulk transfer or storage of toxic fluids and liquids. Pipe freezing services in Saudi Arabia allows safe maintenance works without interruption of processing systems. Typical pipe content may water, acid, paints and coolants.
Procedure for Pipe Freezing Services includes fabrication of metal jackets as per the product pipe size and it is installed over the pipe. Insert liquid nitrogen into the jackets where the temperature reaches negative (-ve ) and the liquid nitrogen freezes the pipe. Necessary modifications can be performed on the pipe without liquid draining. Pipe freezing services can be more effective of the diameter of pipe ranges from ¼ ‘ to 24 “.Pipe freezing may not be suitable if the pipe size more than 24” medium or elevated temperature and liquids with different freezing point or pipe is too small with complex geometry. Selection of pipes shall be either copper or steel and the pipes shall have sufficient capacity to withstand pressure created by the ice plug.
NITROGEN SERVICES
EIWAA Oil and Gas Services is a NEOM Approved vendor for complete Nitrogen services in Saudi Arabia 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 Saudi Arabia including Nitrogen filling, Nitrogen lifting and Nitrogen pressure testing services, EIWAA is your trusted partner to meet your Nitrogen services. Nitrogen purging services is used for the replacement of a hazardous atmosphere with an inert dry atmosphere. Nitrogen purging may either displacement or dilution. All the major storage tank terminals in Saudi Arabia, our Nitrogen filling, Nitrogen Purging Services are used to create a safe and controlled environment by removing unwanted gases. Nitrogen Purging services in Saudi Arabia 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 as the name suggests, it is a technique to clean and prepare pipelines by nitrogen gases. Moisture, contaminants and other impurities are removed by nitrogen filling services, and it improves the remaining life span of equipment’s and pipeline. Our Nitrogen pressure testing services in Saudi Arabia helps to identify potential leaks or weakness to ensure integrity or performance. Nitrogen pressure testing services are widely used in power plants, pipelines, vessels and other pressure containing equipment’s. N2 Purging in Saudi Arabia 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
- N2 Purging Services for transformers and volatile electrical systems
- Pipeline drying and purging to control oxygen concentrations especially used in pipeline Maintenance services
- Nitrogen Helium Leak Testing Services
HYDRO TESTING SERVICES IN SAUDI ARABIA
Pressure Testing Services is important in Pressure Vessel Inspection and Certification. Hydro Testing shall be conducted as per the API 570/ASME SEC VIII regulation by authorized API 570 Inspection Engineers. EIWAA Oil and Gas Services always use calibrated pressure gauges and pressurizing kit to execute the pressure testing for Pressure Vessel. Hydro testing services must use a test pressure that is 1.5 times the design pressure or that considers the design and test temperatures.
PIPING AND PIPELINE INSPECTION SERVICES
EIWAA offers the following inspections and certifications using approved NDT Testing and Integrity assessment Inspections:
- Inspections motivated by damage mechanisms.
- Pipeline corrosion rate and remaining life assessment
- Piping hydro testing and certification
- Pipeline pressurization testing
- Pipeline ultrasonic thickness assessment
- Pipeline leak testing for both above-ground and underground pipelines.
- Pipeline corrosion monitoring.
The fluid that is typically clean/fresh water or treated fluid is used in the flushing or hydrostatic testing operation. (Where applicable, a suitable corrosion inhibitor, chloride-controlled water, combination, or mixture of such are used to prevent damage due to water’s negative effect on the pressure vessel. A pneumatic test is a pressure test that uses dry compressed air, inert gas, water, or soap solution to demonstrate the integrity of the pressure vessel, nozzle, chamber, reinforcing pads, etc.
FREQUENTLY ASKED QUESTIONS
Hydro testing Services follows the below safety regulations & recommendations,
- Apply the warning signs and tigger tape to isolate the hydro test locations
- Never hydro test a system’s components against a closed valve.
