PRODUCT GROUP 2
|
| |
|
|
By minor vertical travel of piping and related
components due to thermal expansion, spring hangers are used to provide
elastic load transfer.
The
requirements for these components are consistent performance and
maintenance-free operation.LISEGA spring hangers prove themselves
especially advantageous in service via the following features:
 |
surface protection through galvanized finish |
|
no welded seams |
|
special pre-relaxed springs |
|
adjustable blocking system |
|
approval by independent authorities |
|
|
LISEGA spring hangers and supports are preset at works to the installation load and blocked in both directions of movement. Blocking is necessary to take up additional loads during pickling, flushing, or hydrostatic test. The factory settings are carried out on electronically controlled test benches:
|
values set at the factory are stamped onto a reveted plate. |
|
the installation position is marked on the travel scale. |
|
cold and got settings are marked on the travel sclae with white and red sticker respectively. |
|
the blocking device can be blocked in any position. The blocking pieces can be reinserted in any required position. |
Deliveries of approximately 1,000,000 LISEGA spring hangers and supports worldwide demonstrate their particular reliability.
