4.0 USP Installation
4.1 Preparation
①
MORKO will evaluate the application and give instructions with respect to the location and
placement of the USP transducers(See the figure4).
②
To maximize the USP effect, the USP installation should take place after the equipment has
been cleaned. For heat transfer performance USP has been shown to be more effective when
the system starts from a clean condition.
③
The welding process must be done while the equipment is off-line to remove the risks
associated with high process fluid pressure and to eliminate flammable gases or liquids
inside the process equipment barriers.
4.2 Transducer Welding Installation
①
The welding should be done by a qualified expert journeyman welder under the supervision
of a welding inspector.
②
The welding should be done while the system is off-line and any process fluids should be
removed from the system, and any pressure or flammable gases inside the vessel or
process piping should be removed.
③
After cleaning and preparing the welding surface by sandpaper or grinder, the expert welder
shall use the GTAW (Argon) procedure. Welding Inspection is recommended.
The welding must be done as same as the diameter of the wave guide rod. The weld bead
diameter must not exceed 5mm greater than wave guide rod diameter and the inside of
welding part must not contain any slag or gas bubbles to ensure there is minimal
ultrasonic power losses in the weld.
