The A380 maintenance hangar at Xi'an Airport is one of the few core aviation facilities in the Northwest region capable of handling the maintenance and servicing of ultra-large wide-body aircraft such as the A380. The hangar adopts an ultra-large-span steel structure design, featuring a spacious interior with densely arranged equipment pipelines. At the same time, the hangar environment presents special conditions, including equipment oil contamination and fluctuations in temperature and humidity. As a high-grade aviation infrastructure, it imposes specific engineering requirements on the safety redundancy, environmental adaptability, and long-term operational reliability of the supporting pipeline network.

The aviation hangar project involves numerous pipeline points, with distribution covering multiple areas, including hangar operational zones, equipment rooms, and ancillary logistics facilities. The working conditions vary significantly across different areas. Combining the construction characteristics of aviation projects, Baolai Steel provided the project with suitable pipe material solutions to support the overall pipeline system construction of the hangar. In response to the complex on-site environment within the hangar, the manufacturing process was strengthened through enhanced process control, with a particular focus on the consistency of product dimensions and surface protection treatments to avoid installation compatibility issues later on site. All products comply with the corresponding engineering construction standards, with rigorous checks from raw material selection to finished product inspection, and performance verified through multiple physicochemical and mechanical tests, ensuring suitability for the complex and variable actual operating conditions of the hangar while reducing future maintenance pressures.

As a domestically comprehensive and strong pipe manufacturing group, Baolai Steel possesses special equipment manufacturing licenses and complete ISO three-system certifications. The company’s technical center can conduct process reviews for key projects and has the delivery organization capability to supply large-scale engineering projects in bulk or in batches according to demand, aligning with the construction schedule of infrastructure projects. Participation in the A380 hangar project is an important practice for Baolai in the field of aviation hub supporting facilities, providing a solid support guarantee for the safe operation of pipeline systems in high-standard aviation infrastructure projects.
