Caterpillar TAURUS 70 - Manual (Page 18)

Turbomachinery Package Specification Taurus 70 Compressor Set and Mechanical Drive
4.2.7 Hydrostatic Testing
Hydrostatic pressure testing of all compressor casings and end caps is done per API 617
for 30 minutes at 1.5 times the maximum casing design pressure, regardless of
application.
Test water is treated with a wetting agent to allow better penetration of
possible casing defects. After the hydro and final magnetic particle test, the casing is
steam cleaned and bead blasted for surface preparation. Afterwards, it is painted per
Solar’s specification ES 9-58.
4.2.8 Shaft Coupling
Solar’s standard shaft interconnect is a Kop-Flex dry coupling.
4.2.9 Preliminary Alignment
The drive train is aligned preliminarily at the factory to simplify final field alignment.
