MH/T 6110-2015 in English

Interpretation of the core content of the standard

MH/T 6110-2015 is the first industry standard in my country's civil aviation field specifically for the operation and management of aviation fuel pipelines. Its technical framework includes three core modules:

Analysis of key technical requirements

1. Special provisions for trial operation

Standard 4.3.2 clearly requires that filter separators should not be put into use during the initial trial operation. This regulation originated from a fuel contamination accident caused by filter element impurities at an airport in 2012. In practical applications, a three-level flushing procedure is recommended:

2. Innovative requirements for cathodic protection

The protection potential range of -0.85V~-1.20V specified in clause 5.6.2 is more stringent than that of API RP 1632. In practice, it should be noted that:

• When the soil resistivity is greater than 50Ω·m, a strip anode should be used
• A polarity drain should be installed in the AC interference area

Analysis of standard evolution

This standard introduces the concept of pipeline integrity management for the first time (clause 3.2), reflecting the shift from accident response to risk prevention. Compared with the 2008 version of the industry guide, the main progress is:

Implementation suggestions

1. Digital management: It is recommended to establish a GIS system to integrate the detection data required by Article 6.6
2. Staff training: Special attention should be paid to the qualification requirements of line inspectors stipulated in Article 5.2.4
3. Technology upgrade: Intelligent internal detection should be implemented first for pipelines that have been in operation for more than 20 years (Article 6.5)
