Jet A1 pipe material
Jet A1 pipe material
(OP)
Hi everybody
I am working as the client on an above ground storage tank diesel and Jet A1 installation in the DRC. The question of whether the piping for the Jet A1 fuel tanks should be stainless steel has arisen. The supplier has said that they have never installed stainless piping but this is Africa. Are there any codes which stipulate stainless piping for Jet A1 (in particular API) or is carbon steel ok. I am only worried about contamination of the fuel. Any help would be greatly appreciated.
Thanks

but I would find a USARMY or military text reference that specifys this.
Internal piping coatings and connsiderations for static electricity grounding are some other design considerations.
This is useful:

Carbon steel, without internal coating.

One problem with the ss was the client specified Sch5s ss, presumably to save money. Straight pipe was available in Sch5s but the fittings only available in Sch10s. The difference in wall thickness created a small weir.
The small water content in the JetA1 pooled at this change in section in a stagnant line & was sufficient for microbiological growth to occur. This was then pumped into the aluminium fuel tanks of a jet fighter. Over time the wing tanks corroded (MBC) at the inlet nozzle beneath the wing. When an operator connected the refulelling hose it pushed right into the wing tank. Luckily there was no fire b ut the operator was covered in JetA1.
New installations required the pipes to be sloped and any Sch10s fittings to have the obvert of fittings ground so no weir existed.
