A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines.. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.
1959: On July 1, a petroleum pipeline exploded, and burned for 7 hours in Coatzacoalcos. 12 people were killed, and 100 more injured. [ 61][ 62] 1978: On November 1, a gas pipeline exploded and burned, killing 52 people in colonia Benito Juarez, Mexico, and injuring 11 in a town of only 100 people.
A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...
The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...
Both A and B pipes of NS1 are inoperable. Pipe A of NS2 is inoperable, while pipe B remains undamaged. On 26 September 2022, a series of underwater explosions and consequent gas leaks occurred on 3 of 4 pipes of the Nord Stream 1 (NS1) and Nord Stream 2 (NS2) natural gas pipelines, two of 23 gas pipelines between Europe and Russia.

Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
An environmental group on Thursday sued the U.S. government over its approach to examining the harm caused by ageing offshore oil and gas infrastructure, citing the risks delayed decommissioning ...
Hydrogen leak testing. Hydrogen leak testing is the normal way in which a hydrogen pressure vessel or installation is checked for leaks or flaws. This usually involves charging hydrogen as a tracer gas into the device undergoing testing, with any leaking gas detected by hydrogen sensors. [1] Various test mechanisms have been devised.
