Special products





We master manufacture of some parts for instrumentation the assemblies applied to an oil and gas production. Parts are made of new specially designed hard alloy СН8.


Physicomechanical properties of alloy СН8:

Camber                    180÷190 kgs/мм2

Crimp                      500÷520 kgs/мм2

К1с                               13 mPa m1/2 

Hardness                          88÷90 HRA

Density                       14,6÷14,8 g/sm3

Thermal conductivity         95÷105 w/µº C


A hard-alloy friction pairs for face seals, hard-alloy bearings, hard-alloy sleeve bearings are used in high-speed (10000 rpm and above) the submersible pumping units plants (in structure of pump, the input modulus, a hydroprotection, the electric motor, a gas separator), immersion submersible pumps intended for supply edge water with the contents of hard spots more than 2 g/l from oil-wells.

Applying of hard alloys in wearing members of various pump plants makes a construction high-reliable in maintenance and provides a resource of operation not less than 30000 hours.
