Steel pipe piles are an important structural material commonly used in construction and engineering, especially in foundation projects that need to withstand large loads or complex environmental conditions. Steel pipe piles are usually made of spiral welded steel pipes made of carbon steel plates. They have high strength, good bending resistance and excellent impact resistance. They are particularly suitable for offshore water environments and can effectively reduce the impact of ship impact. The following are the common specifications and characteristics of steel pipe piles:

Diameter and wall thickness:

The diameter of steel pipe piles is usually between 300 mm and 1200 mm, and the wall thickness is generally between 10 mm and 30 mm. The specific diameter and wall thickness selection depends on geological conditions, load requirements and engineering design standards.
Length:

The length of steel pipe piles generally ranges from 10 meters to 30 meters, and the length can be adjusted according to different engineering requirements and design loads. When the soft soil layer is deep and a larger bearing capacity is required, longer steel pipe piles are often selected to ensure stability and safety.
Connection method:

There are various connection methods for steel pipe piles, and the common ones include welding connection and mechanical connection. Welded connections can provide stronger structural continuity and bearing capacity, and are suitable for environments with high impact forces; mechanical connections are more flexible and suitable for occasions that require rapid installation and disassembly.
Surface treatment:

Steel pipe piles usually need to be treated with anti-corrosion, and common methods include galvanizing, painting or spraying to enhance their corrosion resistance and service life.
Application scenarios:

It is mainly used in offshore docks, bridge foundations, embankment projects, marine projects and other occasions that require impact resistance and strong bearing capacity. Its advantages are that the construction is convenient and fast, which can speed up the progress of the project, and can effectively absorb deformation and reduce the impact on the surrounding environment and structure.
As an important basic engineering material, steel pipe piles play an important role in construction and marine engineering. By selecting appropriate specifications and construction methods, the safety and durability of the project can be effectively improved to adapt to the complex and changing engineering environment requirements.
