Guiyang Airport’s terminal expansion and office towers required a commercial plumbing system that could support high-traffic public facilities, stable water delivery and long-term operation. To meet these requirements, the project selected Nonleak stainless steel pipes and threaded press-fit fittings for its potable water supply network.
Located in Guiyang, Guizhou Province, the project served an airport terminal expansion and adjacent commercial office spaces. Because the system needed to operate in a busy transportation environment, the project required durable materials, reliable connections and efficient installation.
Commercial Plumbing System Overview
The project used a complete stainless steel water supply system for the expanded airport terminal and supporting office towers. Nonleak supplied 304 stainless steel pipes, threaded press-fit fittings and related connection components.
Project details:
Location: Guiyang, Guizhou Province, China
Project Year: 2015
Application: Potable water supply for airport terminal and office towers
Pipe Material: 304 stainless steel
Connection Method: Threaded press-fit adhesive connection system
This commercial plumbing system needed to serve a large public facility with stable water delivery and minimal maintenance disruption.
Project Scale and Technical Specifications
The project scale shows the trust placed in Nonleak’s stainless steel piping solution.
Key project data:
- 44,716 meters of 304 stainless steel piping deployed throughout the complex.
- 52,049 threaded press-fit connections.
- Unified pipe material and connection method across the project.
- 304-grade stainless steel for corrosion resistance and clean water delivery.
- Designed for long-term operation in a high-use building environment.
For an airport project, system reliability matters throughout the building lifecycle. Therefore, the selected piping system needed to support both installation efficiency and long-term service stability.
Why Threaded Press-Fit for an Airport Complex?
The Guiyang Airport project selected Nonleak’s threaded press-fit adhesive connection system because it matched the needs of a large commercial and transportation facility.
First, the connection method helped improve installation speed. With more than 52,000 connections required, repeatable installation steps helped the construction team complete work more efficiently.
Second, the system supported long-term performance. The threaded press-fit adhesive connection forms a stable bond after installation and helps reduce reliance on rubber O-rings.
Third, the system supported clean water delivery. Combined with 304 stainless steel pipes, the connection method helped reduce corrosion risk and maintain water quality in the building supply network.
Meeting the Demands of an Airport Facility
Airport terminal buildings require reliable infrastructure. They serve many passengers, staff and commercial users every day. As a result, their water supply systems must support frequent use, easy maintenance and stable operation.
The compact design of threaded press-fit fittings helped installers work in complex building areas. In addition, the standardized connection process helped maintain consistent quality across thousands of joints.
The project also required a clean and organized installation. Stainless steel pipes and uniform connection components helped create a durable system that could support long-term operation in the expanded airport facility.
Long-Term Performance and Project Value
Completed in 2015, the stainless steel water supply system at Guiyang Airport’s expanded terminal and office towers has supported reliable operation for more than nine years. This project shows how suitable pipe materials and connection technology can support large-scale commercial plumbing systems.
The project also demonstrates the value of using stainless steel piping in public infrastructure. For airport terminals, office towers and other high-use buildings, stainless steel pipes can help support corrosion resistance, clean water delivery and reduced maintenance pressure.
