Preventative Maintenance
MOST offers a low maintenance stuffing boxes that provide customers with years of service.
Inspection of an operating stuffing box:
1.
During operation, the stuffing box must be visually inspected for leaks and seepage.
2.
If a leakage is noticed, then the source must be identified.
3.
If the leakage is from the bolted flanges/threads, the bolts/thread should be checked for correct
torque.
4.
If applicable, replace the ring gasket if re-torquing the bolts does not correct the leak.
Ring gaskets should not be reused
5.
If the leakage or seepage still continues, the stuffing box needs to be serviced.
Internal Threads:
All internal threads (EU, Line Pipe, etc, depending on model), should be inspected for damage
before and after use.
Damaged threads can compromise the integrity of the stuffing box.
External Threads:
External threads are highly susceptible to damage during transit or from poor storage
conditions. These threads should be inspected for damage before and after use.
Damaged threads can compromise the integrity of the stuffing box.
Bolts and Flanges:
1.
Studded outlets and flange surfaces should be inspected before and after use.
2.
Damaged studs should be replaced with equivalent API spec studs.
3.
All ring grooves should be inspected for damage prior to and after use.
