## Covid-19 - A Note from Gammon Technical Products - Equipment Storage

We know the problem, Fuel volume equals cash flow. If fuel doesn’t flow, there is no dough.

Which makes your job more difficult.

See attached guidelines from A4A and JIG on dealing with the present situation on EQUIPMENT, from a practical point of view. We have added additional suggestions below.

There is an ATA/A4A (USA) release in addition to the JIG Bulletin 128 (International). See links below.

Not using fuel handling equipment can be dangerous in many ways. Fuel is not stable over time and equipment needs to be exercised.

Filters, tanks, hydrant lines and vehicles all need to be periodically flushed, at a reasonable velocity. But what is a reasonable velocity?

We at GTP recommend at least 3 feet per second on suction pipes and 6 feet per second on discharge pipes. In metric measure, that’s about 1 meter per second suction and 2 meters per second discharge.

In filter separators, we recommend achieving the maximum achievable velocity at least once a week for at least 5 minutes.

All of this can be difficulty, especially on long hydrant system runs, if they are not "loops" set up to allow recirculation.

In addition, displacing fuel means a volume must be transferred. Lets take a hydrant line, 8" (200 mm) in diameter and 1000' long, 340 meters.

That pipe alone holds 2,600 gallons/9,800 liters.

To achieve 6 fsp/2 m/s, you must flow it at a velocity of at least 1,000 gpm.

H M Gammon’s Velocity Formulas (Howard Gammon’s math skills were amazing)

____________________________________________________________________________________

As an example, 300 gpm calculations:

(GPM/pipe size in inches squared) x 0.4 = FPS (feet per second)

So, 300 gpm divided by 16 (4 x 4 for 4” pipe) times .4 = 7.5 feet per second.

____________________________________________________________________________________

(LPM/pipe size in mm squared) X 20 = M/s (meters per second)

So, 1,135 lpm divided by 10,000 (4” pipe is approximately 100 mm, so 100 x 100 is 10,000) x 20 = 2.27 m/s.

____________________________________________________________________________________

The documents below provide a starting point only. Be safe and never assume that fuel is good or equipment is safe to operate if the system has not been used, recirculated or flushed regularly. One oil company recommends all equipment be flowed at least twice a week, to maximum attainable velocity.

Yours may vary, but we agree that equipment must be exercised, filters must be flowed and systems flushed or recirculated.

Microbes grow quickly and a coalescer that doesn't flow is an incubator for microbes.

## IMPORTANT NOTE

* 0 - 15 psi DP Gauges fitted with proximity switches CAN NOT be set to accurately trigger at 15 psi

*0 - 30 psi DP gauges fitted with proximity switches can be adjusted down to a 15 psi trigger point

*If you wish to modify a DP gauge from 30 psi > 15 psi or 15 psi to 30 psi, the internal spring AND the faceplate must be changed

15 psi & 30psi Gammon Gauge springs are different a different colour SEE HERE

# It's NOT Rocket Science !

### Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.

— Captain A. G. Lamplugh, British Aviation Insurance Group, London. c. early 1930's

### I do not understand it.

— Philip A. S. Franklin, Vice President of the White Star Line, sobbing to reporters the day after the Titanic sank, 15 April 1912.
