Hydrostatic testing procedure -

A boiler hydro test is a stress procedure used to determine the integrity of all aspects of a given boiler unit. The test involves filling the boiler with water and pressurizing to at least one and half times the maximum specified operating pressures for a short duration. During this test, if there are any defects in the boiler structure, the test will fail, and the boiler will not pass inspection for routine use.

Standard boilers units in use in thermal power plants have multiple welded components, with each weld representing a potential point of weakness that could lead to equipment failure, leaks, and explosions. In addition, boiler hydrostatic testing ensures the boilers can withstand the extreme temperatures and pressures expected during routine operation.

Firstly, water is non-toxic and poses no harm to the environment, making compliance with local environmental waste standards easy. Water is also nearly incompressible, making it easy to raise the pressures within a vessel filled with it.

In the case of a boiler unit, raising the temperatures from atmospheric pressure to required test levels will be rapidly achieved. For optimal testing results, water introduced into a boiler for testing should be maintained between 86°F and °F. Additional desirable parameters include:.

To begin the test, the pressure displacement pump is connected to the boiler with an integrated gauge. Next, the boiler is rapidly filled with water with care taken to displace any air pockets within the vessel. The pressure within the boiler should be raised to 1. Once the inspection is done, the pressure within the boiler is further reduced to atmospheric levels, and the water is drained.

The boiler hydro test must be witnessed by inspection officials who confirm the absence of leaks and then certify the boiler accordingly. The frequency of boiler pressure testing varies between locations and mainly depends on assessing various boiler criteria, including age , pressure requirements , and operating history.

The test is used for many reasons: determining if an object will withstand various loads or stresses, detecting leaks in hydraulic systems or pipes, ensuring that equipment functions properly before use, etc.

Hydrostatic tests are conducted by filling an object with water and pressurizing it to test for strength and leaks. The ability to detect leaks in an object is one of the most important reasons why this type of testing should be performed regularly. This article will discuss what hydrostatic testing entails, how it works, and the benefits associated with it.

Hydrostatic testing is an integral part of quality control. Hydrostatic tests are performed to determine the structural integrity and fitness for use of a variety of objects including gas cylinders, storage tanks, and chemical pipelines.

The test works by filling the object with water until it's completely full and then pressurized--ensuring that it can hold up under pressure without bursting open at any seams nor allowing leaks from within its structure. The name comes from when engineers used compressed air as their hydraulic fluid instead of water; the term "hydro" meaning water in Greek and "statikos," which means solid as in static.

Hydrostatic testing also provides a level of confidence that the object will hold up under pressure and withstand exposure to corrosive environments without bursting open at any seams nor allowing leaks from within its structure. Hydrostatic testing is a pressure-based technique used to test the integrity of piping systems, gas cylinders, boiler components, and all other kinds of pressure vessels.

Hydro-tests are commonly done after repairs and downtime to determine if items will operate properly when put back into use.

Hydrostatic testing is a common tool used by engineers to ensure that equipment has been rebuilt or repaired properly. It's most commonly employed for DOT-required containers with the aim to work out any potential leaks and verify it is fully safe for use.

This is important because if you have a DOT-required container and it's not been properly tested, what is inside the canister could be contaminated. A hydrostatic test will bring up any potential leaks in equipment and also show if there are any structural problems with the exterior or interior of the tank that might lead to leaks later on.

Hydrostatic testing is done by filling containers with water at high pressure until they reach their designated capacity; this allows engineers to see where leaks appear signifying small holes as well as find out how strong each welded seam really is.

This type of inspection provides much more information than just visually inspecting your stainless-steel containers because you're looking for inconsistencies and then repairing them before something goes wrong during use.

The process works because water will breach any gap between two pieces of imperfectly sealed pipe if there's enough pressure applied to force its way through; this means every time we turn on our faucet and allow water into the pipes below ground, those leaks are being detected without us ever knowing about them.

Hydrostatic testing is also mandated by the Department of Transportation DOT as part of the certification process to show that a cargo tank and its fittings are able to maintain an airtight seal under pressure when being filled or emptied. This ensures that they do not leak any flammable fluids during their use.

The DOT's rules mandate this test at present intervals in order to prevent catastrophic damage in case there was a puncture somewhere along the way.

The best way to avoid disaster is to have an experienced technician perform your hydrostatic testing. There are two main types of tests:. Just because you've done this type of testing before doesn't mean it's time to stop!

Hydrostatic testing should be performed every year after installation or sooner if there has been any change in environmental conditions. Working with a company that offers hydrostatic testing services can be more beneficial than purchasing and operating the equipment because of cost, time, and resources.

Additional benefits include a faster turnaround time, increased safety for your staff and customers resulting in improved product quality assurance; decreased repair costs; minimizing risk exposure and liability claims. A team of highly trained hydro-testers can help chemical, industrial or other companies to stay compliant with hydrostat specifications.

Hydrostatic testing provides many benefits for a business by ensuring the quality of their product. For example, this process can be used to ensure that equipment is functioning properly before use and also detect leaks in hydraulic systems or pipes.

What is hydrostatic testing? It ensures that the weld joints and flanges are fitted properly, and confirms that the material used has the required strength to sustain the pressure. This is especially important in industrial applications involving the storage and transportation of fuel, chemicals, and other hazardous materials that can explode if they fail under pressure, and in pipelines, where a weakness in the structural integrity of a pipe could dramatically impact both the environment and our economy.

A hydrostatic test should only be performed by skilled personnel to avoid safety incidents. The procedure will differ slightly depending on the type of vessel being tested, but the goal of all hydrostatic testing is to examine the strength of the unit under test and identify leaks or weak spots.

Once the air is removed from the vessel and it has been brought to test pressure typically 1. Pressure, media and ambient temperature readings are taken digitally or with a chart recorder at specific set frequencies determined by industry codes and standards.

The tests can take anywhere from 2 to 12 hours, depending on the application.

Preparation for testing	Article Talk. The process works because water will breach any gap between two pieces of imperfectly sealed pipe if there's enough pressure applied to force its way through; this means every time we turn on our faucet and allow water into the pipes below ground, those leaks are being detected without us ever knowing about them. Home Applications What is Hydrostatic Pressure Testing? Hydrostatic testing is an integral part of quality control. Following the testing service, cylinders are stamped on the neck area indicating the month, year and testing station number.
Common Applications of Hydrostatic Testing	This enables our technicians to flag potential leaks and determine how strong its welded seams actually are. While the exact procedure will vary slightly according to the precise vessel, a hydrostatic test generally follows the below steps:. The hydrostatic pressure test procedure begins with an external inspection of the cylinder, looking for physical damage, gouges, dents, and corrosion. Particular attention is paid to repainted cylinders as they could have been heat-treated or had dents filled in. Dents, corrosion, and heat-treating can all negatively affect the integrity of the compressed air cylinder and lead to a failed result—most tanks that fail inspections before pressure testing are due to poor external condition. The next step of the hydrostatic test procedure is to drain the cylinder before removing the valve. If the cylinder requires servicing and a test, its repairs can also be performed at this time. The technician will then assess the neck thread and internal spaces for corrosion and deterioration using telescopic mirrors. Meticulous inspection is vital as steel cylinders are susceptible to rust and some more so depending on how they were manufactured. Certain brands will rust more than others due to the amount of carbon used in the steel. The rust within the cylinder also provides the technician with a gauge of how well the cylinder has been maintained, as internal rust is often the consequence of negligence. If a cylinder is filled with moist air from a station that has not adequately maintained its filters or compressor, this may also be another reason for cylinder rust. There may be oil found if this is the case. After the inspection is complete and the cylinder has been emptied, it is connected to a pressure testing panel. The cylinder is pressurised and filled with a liquid, often water. It is filled to the desired pressure, known as the test pressure. The cylinder is held at the test pressure for a period; the time varies depending on the cylinder being tested. The pressure is then slowly released, and the expansion is measured on a manometer tube. The recorded expansion is measured against Australian standards to see if the cylinder has passed the hydrostatic test and is fit for use. The cylinder is disconnected from the test panel and inverted to drain, after which warm air on the cylinder heater is used to dry the cylinder. The cylinder is stamped, filled, leak tested, and the test certificate is completed. The equipment is also tagged to demonstrate that it is safe for use. If a pressurised pipe, cylinder or vessel passes the hydrostatic test, it passes a national Australian standard under:. At Newcastle Safety Servicing, we can generally have this process complete and your cylinder ready to go within 72 hours. How often a cylinder requires hydrostatic testing depends on its application, the industry in which it is used and how often it is utilised. For example, cylinders used in SCBA breathing apparatus equipment require hydrostatic testing every 3 to 5 years, depending on where the equipment is applied. On the other hand, SCUBA cylinders should be tested every 12 months. Cylinder hydrostatic testing frequency is carried out with Australian Standard Following the testing service, cylinders are stamped on the neck area indicating the month, year and testing station number. If a cylinder does not have a current test stamp, it will not and should not be filled and used. Opting for a professional service provider with experience in hydrostatic testing is often more cost-effective, efficient and reliable than owning and operating the equipment yourself. As well as a faster process and greater quality control, this approach can cut repair costs, bolster staff safety, and in turn lower the risk of liability claims. Lastly, as mentioned above, regular hydrostatic testing is essential, not just once but annually after installation — or more frequently if environmental conditions have changed. Hydrostatic testing helps your business to verify the structural integrity, performance and safety of pressure vessels before they are put into service. Plus, it can identify any leaks in hydraulic systems or piping. Working with a wide scope of industrial equipment, we offer a certified testing station to provide cylinder hydrostatic testing. We pride ourselves on excellent service and meticulous testing procedures. Hydro testing a new water line essentially begins during the design phase. Understanding testing factors during design will enable the water professional to prepare for obstacles that may arise during the testing process. The hydrostatic test parameters must be clearly defined during the design phase and stated in the project specifications. Duration of the test is two hours. Special consideration must also be given when multiple piping products are used. A test pressure of psi will be detrimental to weak materials, such as polyvinyl chloride PVC rated at psi, which also does not have a safety factor of 2 and surge allowance of psi included in the design, compared to the stronger ductile iron that does. Any material not designed for the specific pressures should not be used and should be isolated from any section of a line to be tested at higher pressures. Complimentary on-site training services are provided upon request by McWane Ductile product engineers or sales representatives to ensure installation crews are empowered with the knowledge to complete the process. Engineering professionals often include on-site training by the manufacturer in the project specification to ensure training is completed. There is also a benefit to documented standards compared to word-of-mouth training. How many times in your life have you encountered a situation such as this one: A newlywed wants to cook Thanksgiving dinner. Her husband does not understand why she is cooking a 5-pound turkey in a pound pot. The bride responds, "That's the way mom did it. Her response, "That was the only pot I had! We may chuckle a little, but this happens all too frequently in the field. Anyone who has searched for a leak will attest to the importance of proper installation. WARNING: The testing methods described in this section are for water-pressure testing only. These procedures should not be applied for air-pressure testing because of the serious safety hazards involved with compressed air. Also, pipelines intended for buried service should generally be tested with the backfill in place. The trench type specified for the project is intended to balance the external forces involved but will not eliminate movement. Therefore, the number of times a line is exercised may vary. Installers may, at times, have a misconception that water lines do not move because of earth loads of six to eight feet, for example. Water temperature is not typically a huge factor during hydrostatic testing but must be considered at times. Internal pressure will decrease as water temperatures decrease-to the point when the fluid begins to freeze, which then creates a substantial issue. Alternatively, pressure will rise as water temperature increases. If a water line installed in the winter is filled with city water at 60 degrees Fahrenheit and the ground temperature is 32 degrees Fahrenheit, the water will cool and the pressure will drop. Conversely, the internal pressure may increase for an above-ground line installed during summer months filled with 60 degrees Fahrenheit water and ambient temperature of 90 degrees. This is especially true if the line is exposed to direct sunlight. A common mistake is for installers to chase a leak for extended periods of time, only to find the line will eventually pass the hydrostatic test without changing any parts of the water line. Considering the allowable make-up water may alleviate this issue. The same information may also be obtained in seconds via the McWane Ductile Pocket Engineer. The Mc Wane Ductile Double Bump protocol is an excellent diagnostic process written for operators to differentiate a leak from trapped air:. If the amount of make-up water remains the same or slightly improves, this is an indicates trapped air. A substantial increase in the amount of make-up water as the pressure is increased indicates a leak is present. Let's be perfectly clear: An air test is absolutely not the same as a hydro test. We recommend using hydrostatic test procedures for all water lines if possible. The dangers of compressed air cannot be over emphasized. Think about it, you have installed a water line - test with water. If, as a last resort, testing with air is the only option, there are items of concern:. LINKEDIN YOUTUBE info araner.
