1.Cairns Port Construction Project, Australia
In 2019, the construction project of Cairns Port in Australia was officially launched, aiming to improve the port's carrying capacity and operational efficiency. The project uses LSAW pipes of API 5L X52 specification, with an outer diameter of 2200 mm, a wall thickness of 16 mm, a length of 24 meters, and a total volume of 637 tons. These pipes, as the main support of the port platform, have the characteristics of large diameter and thick wall, and can withstand the huge pressure and load in port operations. As an important logistics hub in Australia, the construction of Cairns Port will greatly enhance the region's cargo transportation capacity and lay a solid foundation for future economic development.
Project: Port of Cairns in Australian (2019)
End user: Port North
Description: LSAW PIPE FOR PORT CONSTRUCTION, AS THE MAJOR SUPPORT FOR THE PORT PLATFORM, BIG SIZE DIAMETER WITH HEAVY WALL THICKNESS.
OD 2,200 MM X WT 16.0 MM X 24 M API 5L X52 637T

2.ArcelorMittal Project
The application of LSAW pipes is also indispensable for ArcelorMittal, a leading company in the global steel industry. The project uses LSAW pipe piles of API 5L PSL1 X70 specifications, with an outer diameter of 1829 mm, a wall thickness of 22/27 mm, and a length ranging from 24 meters to 40.35 meters. These pipe piles are treated with special coatings to enhance their corrosion resistance and service life, making them suitable for various harsh environments. ArcelorMittal's project not only improves the efficiency of steel production, but also contributes to the sustainable development of the global steel market.

3.Brightwater Marine Outfall Pipeline Project
The Brightwater marine discharge pipeline project is an important environmental protection project that aims to protect the marine ecology through an efficient discharge system. The project uses LSAW pipes with specifications of 2135 mm outer diameter, 16 mm wall thickness and 12 meters in length. The design and manufacture of these pipes meet strict environmental standards to ensure that there is no pollution to the marine environment during the discharge process. Through this project, Brightwater not only improves the efficiency of the discharge system, but also contributes to the protection of the marine ecology.

4.Trestle 1A pile project
The Trestle 1A pile project is a comprehensive waterside project involving corrosion control of 586 steel pipe piles. The project uses a variety of technical means, including encapsulation and coating of the piles, to ensure that the piles maintain good durability in different environments both underwater and above the water surface. By protecting the piles, the project team effectively extended the service life of the structure and ensured the safety and stability of the waterside project.
Project: Trestle 1A Pile
Description: This waterfront project included corrosion control of 586 steel pipe piles by a combination of pile encapsulation from approx. El. -2 ft to +6 ft and application of coatings to the bearing cap assemblies at various elevations above the FRP pile jackets.

The above four projects demonstrate the importance of LSAW pipelines and steel structures in international infrastructure construction. From Australia's Cairns Port to ArcelorMittal's steel project, to Brightwater's marine discharge pipeline and Trestle 1A pile project, these projects not only reflect the progress of modern construction technology, but also reflect the efforts of various countries in infrastructure construction and environmental protection. With the continuous increase in global investment in infrastructure, more similar projects will be launched in the future to meet the growing market demand. Through high-quality LSAW pipelines and steel structures, these projects will provide strong support for the economic development and sustainable construction of various countries.
