6-4.19 General Maintenance Work
a.
Pipe Threads
A number of fittings and equipment items have small diameter threaded pipe connections. All pipe threads are subject to
damage from galling or mishandling. If a thread, male or female, is damaged only lightly, it can be repaired by merely
chasing the thread with the proper size pipe thread die or tap. Badly damaged threaded nipples or fittings should be
replaced.
b.
Grounding Systems
Grounding systems are used extensively on all equipment. If the ground connection is broken, it must be promptly
replaced. If the ground rod has been broken, it should be promptly replaced with one of the proper length. Broken
ground cables must be promptly replaced.
c.
Roadway, Berms, and Drainage
Under some conditions, corrective maintenance may be required to handle repairs to damaged roadways, tank berms,
and drainage systems. Such work should be handled expeditiously due to the fact that these facilities are also required
for safe and efficient operations.
d.
Table 6-1, entitled Maintenance Troubleshooting, Piping, Hose, Valves and Fittings, will aid maintenance
personnel in relating problems in this area to the cause and the recommended action. Most maintenance work other than
on the major equipment such as the pumps will involve piping, hose, valves and fittings.
