From May 23rd to May 25th, a delegation composed of Saipem Group, Arcelo Mittal, and CNOOD conducted the factory audit for the overseas order QUILUMA&MABOQEIRO PROJECT (hereinafter referred to as the "QM project") undertaken by Ziking. Previously, the tripartite delegation had already completed an on-site inspection of Ziking's plant in Zhongshan.

The QM project is the overseas order with the most diverse specifications, the most comprehensive product types, and the vastest range of steel grades that Ziking has taken on in recent years. It also has high technical requirements for welding, Non-detective testing, profiling, size, and other aspects. The project is in Angola, and the products will compose the superstructure of the gas field development platform. It will significantly increase Angola's liquefied natural gas production capacity and service scope upon its completion.

The delegation confirmed the production details, such as document approval status, drawings, production progress, welding, NDT, profiling, packaging of finished products, and delivery time after they arrived. They also visited the manufacturing plant in Hefei and inspected the trial profiling of steel pipes on the spot. Ziking and the delegation reached a consensus regarding the whole manufacturing process after the four-day in-depth communication and discussion between the two places. The delegation expressed high satisfaction with Ziking's production capacity, qualifications, management system, and other aspects.
