Investigation revealed that Zhongding failed to replace temporary gaskets and caused the disaster/Xingda Power Plant exploded and three people were involved in the crime of fire

An explosion occurred at the Xingda Power Plant in Kaohsiung on September 9 last year. After a year of investigation and identification, the Qiaotou District Prosecutor's Office launched a search and summoned six suspects to the case. The prosecutor found that Zhongding Company allegedly failed to replace "temporary gaskets" with "official gaskets" during construction, causing the natural gas pipeline to withstand high temperatures and dissolve on the spot after being put into use, causing a natural gas leak and explosion. Two Thai piping workers and a Thai piping foreman were found guilty of violating the criminal law and were ordered to pay bail of NT$100,000 and restricted from leaving the country. The other three were asked to return.

Do not rule out the next round of interviews

It is understood that this is the target of the first wave of investigation. The entire case is under investigation. It is not ruled out that the next wave of interviews will be launched to trace the contracting and supervision process of Zhongding Company and Taipower to clarify the true nature of the accident.

Inspection and investigation revealed that in May 2019, Zhongding and the American company Qi Energy Technology jointly won the bid for the "Procurement and Installation Case of Xingda Power Plant and Taichung Power Plant Gas-fired Recirculation Generator Units and their Workshops and Related Facilities and Equipment" handled by Taipower's Nuclear Thermal Power Generation Engineering Office. Zhongding Company was solely responsible for the construction and installation of related power generation facilities. The prosecutor pointed out that Zhongding Company's piping operations and supervisors violated the "GT#2-2 Natural Gas Heating Area Natural Gas Pipeline System Installation and Test Procedure" specification when installing the lower end pipeline of the PCHE (Printed Circuit Board Heat Exchanger) of "GT#2-2 Unit". The staff did not replace the "temporary gasket" used for testing with a high-temperature-resistant "official gasket" before the system was officially put into use.

At 8pm on September 9 last year, after the GT#2-2 unit was put into operation, the temperature of the natural gas in the pipeline rose rapidly. The "temporary gasket" could not withstand the high temperature and instantly melted at the joints of the pipeline. The high-pressure natural gas immediately leaked and ignited a fire. The powerful explosion not only destroyed the pipeline and surrounding auxiliary equipment on the spot, but also the violent fire and shock waves spread to surrounding buildings. Fortunately, no one was injured. Through professional fire appraisal and evidence reinforcement, the prosecutor launched an operation on the 6th of this month, directing the Gao City Investigation Department to search a location, seize construction drawings and related information, and summon six people for questioning.
