Tungsten Alloy Shielding Tube & EFP Test

There are various kinds of test for penetration of EFP (explosively formed penetrators). The first method is utilizing impulse X radiography to know the speed and attitude of EFP before or after penetrating, residues of EFP after penetrating and the fragments after penetrating target. Because strong flashing light and smoke accompany with the process of penetrating. For that, the only method to know the influence of EFP on target and the situation after penetrating target is adopting X-ray radiography. So impulse X-ray radiography has significance for research on penetrating mechanism of EFP. However X-ray may do harm to health during test. So the protection to researchers is necessary. Tungsten alloy shielding tube is made of tungsten alloy for protecting researchers from damaging of X-ray. Tungsten alloy shielding tube has good performance of radiation to radioactive substance for the high density of tungsten alloy. Otherwise, compared with lead, tungsten alloy is more environmentally friendly，and tungsten alloy is non-toxic and non-radioactive.

The second method is penetrating vertical target, aftereffect target or the target which is assigned at a definite angle. The third method is utilizing tank to test the damage of EFP. The tank can heel at a definite angle to simulate the attacking angle and distance of terminal sensitive projectile during flight. The test can prove the actual effect. The forth method is utilizing terminal sensitive projectile system to attack the actual target so that can prove the efficiency of the whole weapon system.
