How do you calculate allowable leakage for HDPE pipes uring pressure hyodro pressure testing?
Wiki User
∙ 10y ago
0.2 x(dia of pipe)x(length of pipe)
For examble if you have 100mm diameter pipe and 50 m length ..
0.2x0.1x50= 1 litre and this is your allowable value

How is bug leakage different from bug release?
Bug leakage: Bug leakage is something, when the bug is discovered by the end users or customer, and missed by the testing team to detect, while testing the software.ORA defect which exists in the application and not found by the tester which is eventually found by the customer/end-user.Bug release: A bug release is when a particular version of software is released with a set of known bug(s)/defect(s). These bugs are usually of low severity/priority. It is done when a software company can afford the existence of bug in the released software rather than the time/cost for fixing it in that particular version.It is the core responsibility of Software testing company to find the bugs at the earlier stage so that a good product can be handed over to the client.
What are the roles and responsibilities of testing and commissioning engineer in substation?
There are a great many. but to keep it simple: (a) pressure-testing the cables/switchgear/transformers/etc. (i.e. testing the insulation using high-voltage test sets); (b) testing the operation of the switchgear; (c) testing the operation of the protective relays. ...but lots more.
What is difference between pneumatic test and air test in pressure vessels?
Pneumatic pressure testing of pressure vessels is done to check the leakage for any leakage where as hydraulic pressure testing is done to check the vessel for its strength.
What is defect leakage?
Defect leakage formula is software testing metric to calculate the number of defects that went undetected to next phase(s). Defect leakage is a important metric that indicates the efficiency of process, test procedures, testing phases. Defect leakage can be calculated across different phases with in SDLC. However, Defect leakage is usually calculated for the number of defects that went undetected to production environment. Defect leakage is calculated as below Number of defects found in current phase that were supposed to be found in previous phase Defect leakage = ------------------------------------------------------------------------------------------------------------------------- X 100 Number of defects found in the previous phase e.g. If 40 defects were found during product testing and 5 defects were found in UAT and 2 in production environment then defect leakage % will be 17.5 % ((5+2)/40*100)
Where a pressure gauge would be used?

What is a low pressure closure?
Low Pressure Closure Test The low-pressure closure test shall be performed with the seat sealing surface interface clean and free from oil, grease, and sealant. Any leakage at the seat sealing surface interface, behind the seat ring, or through the disk on the open side of the valve shall be detected when bubbles are observed coming from the closure (disk, seat, and seat ring), which is either covered with water or coated with a soap or similar solution. When closure testing gate, and ball valves, the valve manufacturer shall use a method of testing seat leakage that fills and fully pressurizes the body cavity to the test pressure between the seats and the bonnet area, as applicable, with the test fluid. This will ensure that no seat leakage can escape detection because of gradual filling of these volumes during the test period. Gate Valve & Screw Down Non-return Globe Valve: The pressure shall be applied successively to each side of the closed valve with the other side open to the atmosphere to check for leakage at the atmospheric side of the closure. Globe Valve: The pressure shall be applied in one direction with the pressure applied under the disc (upstream side) of the closed valve with the other side open to the atmosphere to check for leakage at the atmospheric side of the closure. Check valve: The pressure shall be applied in one direction with the pressure applied behind the disc (down stream side) of the closed valve with the other side open to the atmosphere to check for leakage at the atmospheric side of the closure. Check for leakage using either a soap film solution or an inverted 'U' tube with its outlet submerged under water. If the seat pressure is held successfully then the other seat shall be tested in the same manner where applicable. If unacceptable leakage is found, corrective action may be taken to eliminate the leakage and the seat test repeated. If the valve is disassembled to eliminate the leakage, all previous testing must be repeated upon re-assembly.
What has the author D Dickerhoff written?

Difference between hydro test and hydrostatic test?
Hydrotest is a pressure testing option where a liquid (usually water) is injected into a pipe system to check for structural flaws permitting leakage at normal pressure. Whereas, hydrostatic testing allows the detection of leaks that only become obvious at elevated operating pressures.
What is the maximum pressure for leak testing?
that depends on what you're testing
What is accepetance leakage current in ac hi-pot testing in main bus bar of swichtgear?
i think 100000 ohms
What is the testing procedure for an earth leakage circuit breaker?
You can test this breaker by clamping it onto the earth cable. This will provide you with the measurements that you need.
What does a controlled test mean?
The environment is CONTROLLED. This can be many things, Temperature, humidity, altitude, = pressure. It depends on what you are testing and why. If you are testing a car tire you will control the pressure and the type of surface you are testing it on. Rex
