A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks. A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
This was the first GM ATF to require red dye as an aid in fluid leak detection. Prior to this fluid, GM ATF was the same color as engine oil. Aftermarket ATF was available with red dye. GM DEXRON (B)-licensed products have a license number on the container that begins with the letter B. Example: B10001. This fluid is backward compatible with ...
Rhodamine B / ˈ r oʊ d ə m iː n / is a chemical compound and a dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with fluorometers .
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 ...
In 1966, environmentalists forced a change to a vegetable-based dye to protect local wildlife. [27] Fluorescein dye solutions, typically 15% active, are commonly used as an aid to leak detection during hydrostatic testing of subsea oil and gas pipelines and other subsea infrastructure. Leaks can be detected by divers or ROVs carrying an ...
The oil and whiting method used an oil solvent for cleaning followed by the application of a whiting or chalk coating, which absorbed oil from the cracks revealing their locations. Soon a dye was added to the liquid. By the 1940s, the fluorescent or visible dye was added to the oil used to penetrate test objects.
GM ATF was the same color as engine oil through 1967. Aftermarket ATF was available with red dye as an aid in fluid leak detection. Dexron (B) was the first GM ATF to require red dye. [citation needed] From the 1940s through the early 1970s, ATF contained whale oil as a rust and corrosion inhibitor. [11]
Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines (the pipes and hoses containing the brake fluid) are purged of any air bubbles. This is necessary because, while the brake fluid is an incompressible liquid , air bubbles are compressible gas and their presence in the brake system greatly reduces the ...
