During construction or repair,many diverse materials. One of the most unusual of them can be called a construction cartridge, which in some sources is called installation, industrial or construction.
General information about industrial cartridges
The construction cartridge is single. It is used in a number of mounting piston pistols for clogging into dense (metal, concrete, brick) dowel surfaces. The construction cartridge is often used in repair work on industrial equipment of various industries. It is a sleeve of certain dimensions with a rolled up tip. The construction cartridge has a primer-igniter and is equipped with a small amount of smokeless powder, which does not contain heavy metals (mercury, antimony, lead). On sale, the most often offered are shells with a flange containing a capsule compound. They act on the principle of annular ignition after the striking of the striker occurs along the edge of the flange. Impact composition of the sleeve is held by a wad made of porous pressed powder. After striking the striker, the entire contents of the cartridge are suddenly ignited, giving off energy, by means of which the plugs are clogged. Some industrial cartridges operate on the principle of a central battle like "Boxer" or "Berdan".
Marking of mounting cartridges
In all construction and assembly pistols of the typePC-84 uses 2 types of loose assembly chucks. One of them has a caliber of 6.8 mm and is marked with the cipher "D" (long, 6.8x18 mm). The other is indicated by the letter "K" (short, 6.8x11 mm). Earlier on sale it was possible to find other cartridges with the letter "D" - 22 mm long, and with the sign "K" - 15 mm.
All industrial cartridges with the code "D" and "K"divided by number, depending on the amount of powder charge in them. Due to the amount of their content, they have different energy. The cartridge of each number and cipher has its own distinctive coloration, which is applied to its rolled up tip. So, in accordance with the current technical specifications, the following categories are divided:
• Index - K1 (white); the mass of the charge is 0.2 g; power output - 548 J.
• K2 (yellow); 0.22 g; 603 J.S.
• К3 (blue); 0.25 g; 683 J.C.
• K4 (red); 0.29 g; 795 J.C.
• D1 (white); 0.31 g; 874 J..
• D2 (yellow); 0.34 g; 928 J.W.
• D3 (blue); 0.38 g; 1037 J. J.
• D4 (red); 0.43 g; 1174 J..
LAP Construction Cartridge
In addition to the above ammunition, there are alsocartridges of the family MPU (central battle), created on the basis of the cartridge case, crimped in an asterisk. They are much more powerful and are used in industrial equipment (stamping presses), manufactured in Tula. Supplied in packages of 1 thousand units. The caliber of the construction cartridge MPU - 5,45 mm. They come in 3 colors:
• Index MPU-1 (white); charge weight - 0.6 g; power output - 1644 J.
• MPU-2 (green); 0.8 g; 2192 J..
• MPU-3 (yellow); 1.0 g; 2720 J..
Other ammunitions are used abroad. Construction cartridges of 5x16 mm caliber are rolled and re-clamped sleeves. They can be used in the RPM gun. When working with such materials, it must be remembered that they are all traumatic and flammable. They can not be shocked, heated and subjected to friction.
