Analysis technologies that support reassuring, safe and reliable gas services

To ensure our customers can utilize reassuring and safe city gas services, we make full use of the technologies accumulated over the years such as material failure analysis, corrosion protection technology and chemical analysis, in order to clarify causes and to propose answers against various technical challenges. We apply this approach to all aspects of the LNG value chain ranging from production to supply and gas-consuming equipment.
 

Feature


We have an extremely large number of facilities in our LNG value chain, and face a wide range of technical challenges. In many cases, facilities or equipment trouble cannot be resolved through a simple analysis, and we often have to catch up minute phenomena by precise analysis.   
Tokyo Gas has built up the know-how about analysis and technologies over many years of experience, and established an organization that we can response precisely and swiftly to various technical challenges. Below, we introduce a few representative examples.

 

1. Material failure analysis

This technology estimates the causes of failure by inspecting samples’ fractured surfaces and cross sections, and analyzing adhered substances.

 
Latest analysis technology being deployed
Example: Meticulous observation using scanning electron microscopes
Even the most minute causes do not go overlooked
Example: Observation of microcracks via mirror polishing

2. Chemical analysis

This technology analyzes adhered and other substances with the aim of identifying substances that cause defects and other problems. We can select optimal pre-processing methods based on on-site conditions and sample qualities, and conducts analysis accordingly.

 
Meticulous analysis in progress
Example: Extraction of analysis samples
Identifying substances through various analysis equipment
Example: Identification of organic compounds through FT-IR spectroscopy

3. Technical support

We contribute to improved reliability and cost reductions by providing thoroughly technical support including analysis and proposals for remedial measures tailored to on-site demands.
 
Selection of appropriate materials based on operating environment
Example: Evaluation through long-term durability test
Inspection of gas pipelines
Example: Monitoring effect of cathodic protection for underground gas pipelines
