Pipe bursting is a trenchless method of replacing buried pipelines (such as sewer, water, or natural gas pipes) without the need for a traditional construction trench. "Launching and receiving pits" replace the trench needed by conventional pipe-laying.
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 ...
This led to finding diesel fuel running into a storm drain from a leaking Products Pipe Line 26 inch line. It was unknown how long the pipeline had been leaking. [27] March 11 – Woodpat Pipeline, a 22-inch-diameter hazardous liquids pipeline operated by Marathon Pipe Line LLC (Marathon Petroleum), ruptured in Edwardsville, Illinois. The ...
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 pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.
For example, the water traveling along a tunnel or pipeline to a turbine in a hydroelectric generating station may be slowed suddenly if a valve in the path is closed too quickly. If there is 14 km (8.7 mi) of tunnel of 7.7 m (25 ft) diameter full of water travelling at 3.75 m/s (8.4 mph), [ 20 ] that represents approximately 8,000 megajoules ...
A tiny, 1/8-inch crack in a pipe can release up to 250 gallons of water a day. [3] According to Claims Magazine in August 2000, broken water pipes ranked second to hurricanes in terms of both the number of homes damaged and the amount of claims (on average $50,000 per insurance claim [citation needed]) costs in the US.

2010: Dalian Pipeline disaster – The explosion of two petroleum pipelines and subsequent fire in the port of Dalian, in northern China's Liaoning province on Saturday, on July 17, 2010, caused fatalities, damages and an ecological disaster, releasing 11,000 barrels of oil into the Yellow Sea, and covering up, according to different sources, from 50 to 430 km 2 of sea and coast lines.
Magnetic Flux Leakage Principle [1]. Magnetic flux leakage (TFI or Transverse Field Inspection technology) is a magnetic method of nondestructive testing to detect corrosion and pitting in steel structures, for instance: pipelines and storage tanks.
