Trihedral lead drilling pipes

     Trihedral lead drilling pipe (ВБТС-68) is intended for the transmission of twisting moment from the spinle drill machine-tools of type of ЗИФ-1200МР, ЗИФ-1200МРК and СКБ-7 to the drill pipes at the drilling of searching, quarry and reconnaissance mining holes on hard, liquid and gaseous minerals.

     Trihedral lead drilling pipe (ВБТС-68) of collapsible construction with length of working part 6 m consists of round barbell, overhead reducer with left threads for connection with drive-head carriage and lower reducer with right threads for connection with the tool-joint of drilling pipe.

     The use of trihedral lead drilling pipe as compared to round pipes abbreviates time of clean well-drilling due to the exception of periodic stops of the drilling at the intercept of hydropatrone spindle and wedging of stippler in a barrel pipe.

     Reducers are made on machine-tools with numerical control from steel of brand 40ХН or 45ХГМА with heat treatment and phosphating of threads and outward surface.

     Borings barbells of SBU-100, NKR-100

Used at the percussion-rotary method of the boring drilling of explosive mining holes of use dipping pneumatic percussion tool.
SBU-100 are used at the boring drilling of mining holes on the opened developments, can be used in underground terms, allow to bore mining holes a diameter 105 mm, in to 35 m.
NKR-100 depth is used for the boring drilling of mining holes on underground mountain developments, allow to bore mining holes a diameter 85-105 mm, in to 80 m depth in any direction.
Fortress of drill breeds 6 - 20 on the scale of prof. Protod'yakonova.. The percussion - rotary method of the boring drilling of mining holes in strong mountain breeds is most effective, because these breeds are fragile and easily collapse at the dynamic loadings. Besides it, barbells can be used for the boring drilling of decontamination and drainage mining holes, and similarly other works.
Material of barbells: a shell is a - steel 45; muff, union of - steel 40H.
A muff and union is welded on to the shell on technology of welding a friction.

     Technological column И-КТ-45

Technological column И-КТ-45 was designed for gravel transportation through boring casing and hydrolisation of annular space.

The column consists of:
- Sections 100 pieces. Single section consists of socket, nipple and muff. Section outer diameter - 45 mm. Nipples and muffs have rust flies for mechanical screwing and unscrewing of sections with pipe turning machine of type РТ-1200.
- Swivel wrench - 2 pieces. keeps the column hanging over working floor of pipe turning machine РТ-1200 and preventing muff from rotation caused by rotational movement of pipe turning machine.
- Leading wrench - 2 pieces. Designed to transmit rotational moment of pipe turning machine driver to section nipple.
- Caps - 60 pieces. Caps consist of a case, rod, ring gasket and insert. Such caps are being used to perform trips with semiautomatic elevator МЗ-50-80.
- Cap wrench - 2 pieces.

All of column elements comply with ТУ 27.2-32698053-014-2007.

     Light-weight drill column И-КБН-68х7
