A pipe bomb is a simple type of improvised explosive device, a tightly sealed section of pipe filled with an explosive material. The containment provided by the pipe means that simple low explosives can be used to produce a relatively large explosion, and the fragmentation of the pipe itself creates lethal shrapnel.

The bomb is usually a short section of steel water pipe containing the explosive mixture and closed at both ends with steel or brass caps. A fuse is inserted into the pipe with a lead running out through a hole in the side or capped end of the pipe. The fuse can be electric with wires leading to a timer and battery or can be a common wick such as used in most consumer fireworks. All components are fairly easily obtainable.

Generally high explosives such as TNT are not used, because these and the detonators they require are difficult to obtain. Such explosives also don't require the containment of a pipe bomb. Instead, any sort of explosive mixture the builder can find or make is used. This article is concerned solely with chemical explosives. ... Trinitrotoluene (TNT) is an explosive. ... A detonator is a device used to trigger bombs, shaped charges and other forms of explosive material and explosive devices. ...


Some of the explosive mixtures used, such as black powder, match heads or chlorate mixtures are very prone to ignition by the friction and static electricity generated when packing the material inside the tube or attaching the end caps - accounting for many injuries or deaths amongst builders. If sharp objects, such as nails or broken glass, are added inside the bomb in an attempt to increase the amount of injury, these also add to the risk of premature ignition.


The addition of loosely fixed shrapnel material outside of the bomb can increase the danger of the explosion cheaply and easily. The Unabomber used this method by taping carpentry nails to the outside of his devices. Other variations include using scrap metal or ball bearings. Unabomber is a nickname applied to three people: Theodore Kaczynski, an American terrorist. ... Nickel-chrome plated steel balls A ball bearing is a common type of rolling_element bearing, a kind of bearing. ...


Uses

Pipe bombs are often used by criminals, as well as paramilitaries and militias[1]. They have also a long tradition of "recreational" use for amusement or mischief with no intention to cause injury to anyone - but the dangers of premature ignition, and the inherent danger of shrapnel mean that for that purpose they are much more dangerous than alternatives such as dry ice bomb or spud gun. A dry ice bomb is a simple bomb typically made from a plastic bottle, water and dry ice. ... A pneumatic potato cannon A spud gun may refer to one of two things, a classic childs toy which fires small pieces of potato with a small volume of low air pressure or a large pipe based cannon which uses higher air pressure or explosive combustion to launch much...


Devices made from plastic pipe, such as PVC, or thick walled cardboard tube would not be normally considered as "pipe bombs".


Pipe bomb events

  • Pipe bomb attacks are common during periods of heightened tension in Northern Ireland. On the night of August 7, 2005 two pipe bomb attacks targeted Catholics in the village of Cloughmills of North Antrim in Northern Ireland. The following day, Sinn Féin Councillor Daithi McKay accused loyalist paramilitaries of being behind the attacks.[4]
  • On August 10, 2006 four pipe bombs were found in and around the city of Salem, Oregon, and some suspected a serial pipe bomber was at fault. First, a bomb was found attached to a car in the parking garage of Salem Hospital. Then one was located in the parking lot of a Roth's IGA grocery store. Another was found attached to a car in a parking lot in Dallas, Oregon, and another found alongside a Salem roadway. The Salem Police Bomb Squad detonated the bomb outside the Roth's and rendered the rest of the devices safe. The known victims were all residents of south Salem, and a suspect is still at large. Salem Police are encouraging residents to check their vehicles for pipe bombs regularly. [5]
  • On September 12, 2006 after an attack by militants on the US embassy in Damascus, Syria, a van was recovered, full of conventional pipe bombs strapped to small common household LPG gas canisters. The attackers appeared to have failed to detonate the bombs; however another smaller vehicle did explode outside the embassy during the late morning surprise attack. [2] [3]
  • On October 23, 2006 a university student was detained after saying he had planted two pipe bombs outside the U.S. Embassy in Caracas, Venezuela. One bomb was placed outside an adjacent school, while another was found in a planter 50 feet from the Embassy's entrance. The bombs were designed to scatter pamphlets alluding to the Lebanese guerrilla group Hezbollah. Police evacuated the area and detonated the bombs. No one was injured.[6]
