How fast does Detcord burn?

How fast does Detcord burn?

Unlike black powder, detonating cord contains a core of a very high-velocity explosive that detonates (rather than burns) at a speed of about four miles per second. The core is usually PETN, a high explosive with a velocity of about 22,000 feet per second.

What is the speed of det cord?

approximately 6,400 metres
The velocity is approximately 6,400 metres (21,000 feet) per second.

How does detonating cord work?

Detonation Cord consists of a high-explosive (either PETN or RDX) core wrapped in a reinforced, waterproof, olive-drab plastic coating that transmits a detonating wave. When the explosive core is detonated by a blasting cap, the wave travels along the cord to other blasting caps or explosive charges attached to it.

How much does a cratering charge weigh?

Cratering Charge DESCRIPTION: The 40 pound cratering demolition charge is a watertight cylindrical metal container with approximately 39 pounds of H-6 explosive in its interior.

Does Detcord explode?

cord, detcord, primer cord or sun cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6400 m/s, any common length of detonation cord appears to explode instantaneously.

What is Cordex explosive?

Cordtex is a type of detonating cord generally used in mining. It uses an explosive core of pentaerythritol tetranitrate (PETN) inside its plastic coating. It is commonly the thickness of electrical extension cord and has a detonation velocity of approximately 6000–7000 metres per second.

How fast does Primacord burn?

It detonates along its entire length at a velocity of approximately 23,000 feet (7,000 meters) per second. It is used to create explosive effects and to build reliable explosive charges.

Is det cord flammable?

With the PETN exploding at a rate of approximately 6400 m/s, any common length of detonation cord appears to explode instantaneously. It is a high-speed fuse which explodes, rather than burns, and is suitable for detonating high explosives.

What is a cratering charge?

A charge placed at an adequate depth to produce a crater.

How does a shaped charge work?

The shaped charge was an explosive formed into a hollow cone and lined with heavy metal; upon detonation, the explosive gases and molten metal formed a high-velocity jet capable of punching through armour.

How big is a detonating cord in grams?

Detonating cord is rated in explosive mass per unit length. This is expressed in grains per foot in the United States, or in grams per metre elsewhere. A “grams per metre” rating will be roughly one fifth the “grains per foot” rating.

What was the first detonating cord ever made?

Detonating cord. Detonating cord (detonating fuse) resembles safety fuse but contains a high explosive instead of black powder. The first successful one, patented in France in 1908, consisted of a lead tube, about the same diameter as safety fuse, filled with a core of TNT. It was made by filling a large tube with molten TNT…

What kind of cord explodes at 4 miles per second?

Detonating cord (also called detonation cord, detacord, det cord, detcord, primer cord or sun cord) is a thin, flexible plastic tube filled with PETN ( pentaerythritol tetranitrate ). With the PETN exploding at a rate of approximately 4 miles per second, any common length of det cord appears to explode instantaneously.

How do you detonate a detonator cord?

Det cord can be taped in several rings, to the outline of a military man-sized target and detonated, breaching a man-sized hole into wooden doors or light interior walls.
