The coupling are made by Shtangovye in the following executions and can separately be delivered:
- Couplings from turnkey lyska (normal diameter)
- Couplings without lysok normal diameter.
- Couplings without lysok the reduced diameter.
- Transitional shtangovy couplings
- Shtangovy rewater-transport workers
Couplings are subdivided into 3 classes:
N (T) - normalization
T (S) - hardening of TVCh
P (SM) - a wearproof covering of an external cylindrical surface.
High quality of pump bars is provided with use of the most modern technologies:
- Defectoscopy of initial hire;
- The automated system of heating before the forging excluding possibilities of an overheat;
- Automated high-precision (+ 10 °C) the monitoring system of temperatures at heat treatment of the stamped preparations;
- The strengthening bead-blasting processing of a body of a bar.
According to the application of the Customer of a bar are equipped with centralizers, established on a bar body: scrapers - centralizers motionless, scrapers floating, centralizers of TsVN and mezhmuftovy centralizers. The above-stated production is made of high-strength steklonapolnenny polyamide on complex installation the automatic molding machine.
