Jacketed fuel injection pipe
Open-knowledge reference entry
A jacketed fuel injection pipe (also known as double walled, twin walled or sheathed fuel injection pipe) is a special type of fuel injection pipe fitted to diesel engines.
The pipe incorporates an outer jacket that shrouds the inner high pressure pipe. This jacket is usually metallic in construction and can either be a thin walled tube or convoluted hose. In the event of a burst in the injection pipe the leaking fuel will be collected by the jacket and piped away safely to an alarm device to notify operators of a potential problem.
Jacket fuel lines are found predominantly in marine applications. Adoption in power generation is becoming more common.
Legislation
In 1994 the International Maritime Organization required all ships subject to SOLAS to be fitted with jacketed fuel lines. Existing vessels and new builds constructed before 1998 were required to comply by 1 July 2003.
External high-pressure fuel delivery lines between the high-pressure fuel pumps and fuel injectors shall be protected with a jacketed piping system capable of containing fuel from a high-pressure line failure. A jacketed pipe incorporates an outer pipe into which the high-pressure fuel pipe is placed, forming a permanent assembly.
The public source identifies “Jacketed fuel injection pipe” as open-knowledge reference entry. This brief keeps that definition visible, then builds a research path around Jacketed, fuel and injection.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Jacketed fuel injection pipe”, the useful work is to connect “open-knowledge reference entry” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2024. The linked authority identifier is Q6116136. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1994, 1998 and 2003.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
