Boots columned BKL - 168

The boot is columned eccentric

BKM E

 -

 - - - - - - The BKM E boot is intended for the equipment of a bottom of upsetting columns from pipes in accordance with GOST 632-80, GOST 633-80, and also columns from smooth bezmuftovy pipes for the purpose of the direction them on a trunk of the well and protection against damage during descent in the course of fastening of oil and gas wells with a temperature on a face to ^{2500 C}.

Important feature of this type of boots is the easy razburivayemy nozzle which surface is formed by crossing of two spherical surfaces with incoincident axes of rotation. Thanks to this eccentricity the nozzle is turned and directs a column of casing pipes during descent in the direction of the smallest resistance. Free rotation of a nozzle concerning the case of a boot is provided with the sliding bearing integrated into a nozzle. The nozzle is reliably recorded from axial movement in the case.

Due to spherical shape, the nozzle surface always interacts with a well trunk on a tangent, facilitating descent of a column. Unloading grooves reduce a contact spot by surfaces of a nozzle, increasing the specific pressure of a head upon soil at complications during descent of a column, and significantly facilitate effort during descent of a column.

 - - - - - - - The boot is columned eccentric, the BKM E type it is capable to maintain axial loading not less than 100 tons.

In a middle part of the case of a boot there are also side flushing openings for ensuring circulation of liquid in case of a blockage of openings in a nozzle.

Boots - can be carried out with a connecting short triangular carving, with a trapezoidal carving of OTTM and OTTG in accordance with GOST 632, and also with a carving Batres in accordance with GOST P 51906-2002, with carvings of Pipe Metallurgic Company.

All details placed in the steel case are made of easily razburivayemy materials (details are executed from - the state standard specification 1583-93 aluminum AK5M2 alloy) that allows to razburivat a boot all types of chisels, including PDC chisels.
