2.1.2
Preventative Maintenance Prior to Start-up
2.1.2.1 All air dryers are tested at the factory for leak-tight joints and tightness of bolts;
however, during shipment, some bolts may vibrate loose. We have no control
over the handling our compressed air systems receive after leaving our factory.
To prevent costly problems at start-up and operation, all bolts should be
checked for tightness prior to system pressurization. This will assure gasket life
as well as prevent possible gasket blowout. Gasket joints should be bubble
tested after four or five complete cycles of the dryer, to ensure gaskets are
sealed. Any loose joints will need to be re-tightened and re-tested for leaks.
Following is a comprehensive procedure for tightening all pressurized gasketed
joints. If the dryer includes manual butterfly valves, valves must be totally
closed before re-torquing bolts.
2.1.2.2 TIGHTEN BOLTS IN SEQUENTIAL ORDER (i.e. 0
- 180
, 90
- 270
, 45
-
225
, and 135
- 315
) until final torque is reached.
2.1.2.3 Use ROTATIONAL TIGHTENING until all bolts are stable at final torque level.
(Two complete times around is usually required.)
