炎炎スロット Technology of Corrosion for Safe Use of Gas

Overview

To supply gas safely and to enable customers to use it at ease, we evaluate the 炎炎スロット protection condition of steel gas pipelines and the risk of 炎炎スロット of metal materials used in gas appliances.

炎炎スロット of Corrosion Protection for Buried Steel Gas Pipelines

Cathodic protection is generally being applied to buried steel pipelines with coatings. To further improve the anti-炎炎スロット maintenance and management of buried steel gas pipelines, Osaka Gas is working on evaluating the 炎炎スロット protection conditions by the experiments using a unique test apparatus that we developed. This test apparatus can simulate the actual buried environment.

炎炎スロット of Corrosion Risk for Copper Pipes Used for Hot Water in Gas Appliances

Copper pipes are used for hot water piping of gas appliances. Copper pipes have good 炎炎スロット resistance; however, it can corrode depending on the usage environment. Osaka Gas is conducting research to clarify the 炎炎スロット risk for copper pipes and prevent problems caused by 炎炎スロット of them in gas appliances.
