Internal Lining of Jet Fuel Pipelines

Internal Lining of Jet Fuel Pipelines

Internal Lining of Jet Fuel Pipelines

(OP)
Hello,

I am designing a jet fuel pipeline which runs from an offshore unloading point to an airport.

I understand maintaining quality of jet fuel is essential and some people recommend internal lining to be used on pipelines, but I have not been able to find any standards, guidelines or documentations to support this.
In addition to the cost, one of my concerns is during pigging the pipeline, internal lining to be damaged and quality of jet fuel to be compromised.

I would appreciate and would be interested to hear your thoughts and preferably by referring to a standard, guideline, etc.

Thanks in advance,

Thanks, that was helpful.

RE: Internal Lining of Jet Fuel Pipelines

Although it may have changed since I last did aviation piping, there was no specific requirement to line aviation pipelines or piping. Only the really high grade jet fuel had stainless piping and tanks, most of the rest bare carbon steel.

For a pipeline it is rarely needed. Fuel will transfer to a tank and settle and get filtered on the way out. It is only particles and the odd bit of rust you need to worry about and most of that turns up in the ship bringing it....

Internal coating can restrict some pigging activities and IMO for aviation is simply an expensive luxury which has no impact on fuel quality. Only of your pipeline or fuel ends up with significant water cut, which normally means it isn't suitable for use, do you have an issue.

That's quite a useful spec, but still says pipe can be stl, lined or plain streek. Avoid zinc and copper in wetted parts.

LittleInch,

Thanks for your comments. You’re exactly right. I don’t understand why a jet fuel pipeline needs to be lined where there are filtration after storage tank to filter the fuel. On the other hand, jet fuel is not corrosive to necessitate the need for internal lining (although internal lining is not an effective measure of corrosion protection).

However, I’m confused with contradicting comments. I will try to see if I can find a standard on this.

RE: Internal Lining of Jet Fuel Pipelines

Good luck. I don't think there is one if you haven't been given it by the client as plain carbon steel is good enough for jet fuel.

For the section of piping from tank to airplane, it might be a good idea, but for a pipeline it is excessive, IMHO.

Will this line be a full double containment? We have supplied light gage stainless (sch 5) to be used inside of CS or composite lines where DC is required.

I've been associated with at least 1000 miles of jet carrying pipelines, all carbon steel, no linings were used. Stainless Steel is optional at any point. No galvanizing, or copper is permitted.
