On June 16, a reporter was informed that the Shandong Provincial Safety Supervision Bureau officially approved the investigation report on the "3.11" urea synthesis tower explosion at Pingyin Luxi Chemical Third Fertilizer Factory Co., Ltd., prepared by the Jinan Municipal Government's accident investigation team. The report concluded that Nanhua Chemical Machinery Factory bore direct responsibility for the incident.
According to the investigation team, the explosion occurred due to a lack of awareness regarding the severe consequences of a steam leak in the urea synthesis tower at Sinopec Nanjing Chemical Industry Company’s chemical machinery plant. The improper installation and use of a new leak detection hole structure allowed steam to enter the laminate plates, worsening the situation compared to the traditional welded design. Additionally, the company failed to properly inform users about the risks, leading to steam leakage between the plates and subsequent severe stress corrosion, which ultimately resulted in a major liability accident.
The explosion took place at 21:20 on March 21, 2005, at Pingyin Luxi Chemical Third Fertilizer Factory. It caused four deaths, 32 injuries, and approximately 7.8 million yuan in direct economic losses, sparking widespread concern across the chemical fertilizer industry. Following the incident, the Jinan Municipal People's Government formed an investigation team led by the Jinan City Safety Supervision Bureau, along with representatives from the Quality Supervision Bureau, the Supervision Bureau, the General Trade Union, the Public Security Bureau, and the Pingyin County government. Experts from the Shandong Antai Chemical Pressure Vessel Inspection Center, Jinan Petrochemical Design Institute, and Mingshui Chemical Fertilizer Plant were also invited to participate.
The team conducted two visits to Nanhua Chemical Machinery Factory and the Jiangsu Boiler and Pressure Vessel Safety Testing Center to investigate the design, manufacturing, and after-sales technical service of the R-1102 urea synthesis tower involved in the explosion. By late December 2005, the team submitted a special report to the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, detailing the investigation findings and the nature of the accident.
The report stated that the leak detection pipe of the urea synthesis tower at Pingyin Fertilizer Plant was connected to the 16MnR ply plate using a threaded connection. During operation, the seal became loose or disconnected, allowing steam to leak between the tower plates. Sodium ions in the steam concentrated, causing severe stress corrosion cracking. This led to extensive cracks in the tower before the explosion, resulting in a massive release of medium and ultimately an explosion.
At the time of delivery, the R-1102 urea synthesis tower from Nanhua Chemical Machinery Factory showed no looseness in the leak detection hole during transportation, installation, or use. However, the company failed to warn the user about the potential dangers of steam leakage between the plates, leading to the catastrophic accident. As a result, the explosion was classified as a quality-related (including manufacturing and service) liability accident. Nanhua Chemical Machinery Factory was directly responsible, and the former plant manager, now the party secretary Liu Jinbao, was held accountable for leadership failure. Chief engineer Chen Jianjun, who altered the design of the steam leak detection hole, also bore direct responsibility for not informing the user about the risks under the pretext of confidentiality.
It is worth noting that there had been previous urea synthesis tower explosions in the country, but no official investigation reports had ever been released. The determination of responsibility in this case sparked significant debate within the industry.
