Hydro Testing and Pressure Testing Services:

Pipelines, vessels, elbows, hoses, cargo hoses, pipelines, pipe spools, control valves, actuators, oil suction hoses, firehoses, skids, pressure vessels, manifolds, air compressors, and other items are all subject to pressure testing service rendered by EIWAA.

Pipe spools and chambers can be tested with either air or water (hydro-testing) (Pneumatic Test).

The term “hydro test” or “hydrostatic test” refers to a pressure test used to verify the integrity of a pressure vessel using a liquid medium.

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.

Pressure Testing and Certification

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. To avoid air pockets, the inspector will make sure that blind flanges and gaskets are installed in nozzles and vents for air ventilation prior to the hydrostatic test or hydro test.
During the filling process, keep the vents open at all times. To prevent corrosion, the hydro test medium must be clean fresh water, or when testing stainless steel items, pure fresh water or less chlorinated water must be used.
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 hydro testing pressure gauges is at the top of the vessel with a separate nozzle from the hydrotest pump. The Hydrotest's safety inspections also look for things like barricade areas, suitable gaskets, nuts, and stud bolts. According to the requirements of the ASME/API Code, EIWAA always employs calibrated pressure gauges, chart recorders, and temperature/pressure test recorders.

Pipe Freezing Services

Pipe freezing is a method of liquid nitrogen applied in the outer surface of pipes to lower the temperature of pipes .When the temperature of pipes lower than the pipe fluid below its freezing point, create a freeze plug capable to withholding pressure up to 4000psi.Pipeline freezing is used for valve/pump replacement, pressure testing and HVAC System maintenance etc.Pipe freezing is ideal for pipes varies from ½’to 30 “.Pipe freezing services are used for Refineries, Petrochemical plants, Transmission pipeline, Power Generation, Fire Protection system, office Buildings, Hospitals ,Schools etc. Typical pipe freezing holding time are for ½’pipe freezing ,it is 6 minutes; Pipe freezing for 6” pipes, it is 48 minutes, pipe freezing holding time for 8”pipe is 90 minutes, Pipe freezing time for 12’”pipe is 3 hours, Pipe freezing holding time for 20”pipe is 4 hours etc. Fluid Capabilities in pipe freezing services are water, sewage, oil, glycol, brine etc. Benefits of pipe freezing services are eliminates needs for bulk fluid transfer or storage, eliminates need for draining down system, and venting procedures, enhances safety while working on lines containing hazardous liquids.

Pressure Vessel Inspection and Certification

Around the world, various industries, including the oil, gas, and energy sectors, use boilers and pressure vessels. Pressure vessel equipment is subject to a number of rules and codes, some of which must be in compliance with independent inspection and certification in order to assure safety and operational efficiency. In order to assure that statutory inspections and remaining life assessments are carried out and equipment continues to be safe to use, EIWAA conducts pressure vessel and piping inspection assessments

Our pipeline integrity management and piping inspection services include feasibility studies, budget preparation, reporting, and recommendations, among other things. EIWAA provides a full range of consulting and project support services, as well as the ability to carry out industry-focused Research and innovation contracts. Our professionals are trained and experienced in corrosion, electrochemistry, materials science, and life evaluation.

EIWAA offers the following inspections and certifications using approved NDT tools and Integrity assessment Inspections:

• Certification and Inspection of Above-Ground Pipelines

• Certification and Testing for Underground Pipelines

The surface area of a given asset, such as a pipeline or a heat exchanger, is frequently impossible to determine. When pitting corrosion is the mechanism of damage, we offer a variety of methods to gather the necessary data for an accurate life assessment. The estimated depth of the deepest trench is determined by EIWAA's API Inspection Engineers based on inspection results from just a tiny portion of the surface area using extreme value statistical methods.
The number and severity of the pitting damage determine the scope of the inspection that is necessary. In circumstances when there is excessive or little to no pitting, it is frequently sufficient to inspect 10% of the entire surface. We implement inspection in ambiguous cases by means of sequential decision theory.
