Applications of Large Diameter Steel Pipe
Large diameter steel pipe is widely used in structural applications due to its symmetrical shape, which provides excellent resistance to buckling. The bending strength of a pipe remains consistent in any direction, making it ideal for long, unsupported lengths. Additionally, the radius of gyration of a pipe increases its ability to resist buckling. This makes large diameter steel pipe capable of withstanding higher loads compared to other structural sections.
Drilled Shaft Casing
During the construction of drilled shafts, pipe casing is often required to maintain the integrity of the hole while reinforcing cages and concrete are installed. Using large diameter steel pipe as casing ensures a higher quality finished pile by allowing inspection of the bottom of the hole and eliminating variations in diameter. According to the “Standard Guidelines for the Design and Installation of Pile Foundations” by ASCE, drilled shafts without casing have a lower factor of safety compared to those with casing.
Jacked & Bored Pipe
Large diameter steel pipe is commonly used for jacked and bored pipe installations. This method involves pushing sections of pipe through the ground using hydraulic jacks, allowing the placement of utilities without extensive excavation. Jacked and bored pipe installations minimize disruptions to roads, railroads, homes, and businesses. The ability to splice sections of pipe and the simplicity of drilling into hard ground make large diameter steel pipe an efficient choice for underground utility placement.
Sign Poles, Towers & Transmission Lines
Sign poles, towers, and transmission lines require large bending loads to be resisted at the base of the structure. Large diameter steel pipe offers designers the flexibility to select the exact size needed for their projects, thanks to the availability of various thicknesses. The ability to supply long lengths of pipe, ease of splicing different diameters, and the capability to drill into hard ground make large diameter steel pipe an efficient and reliable choice for these applications.
Caissons are commonly used in bridge applications where drilling into river bed material is necessary to establish pilings or a pier foundation. Large diameter steel pipe, typically exceeding 10 feet in diameter, provides the installation capability for these high-strength foundation systems. The durability and strength of large diameter steel pipe make it an ideal choice for supporting bridge structures.
Combination walls, also known as combi-walls, pipe-z walls, or king pile walls, combine large diameter steel pipe piles with steel sheet piles to create an efficient system. The king pile takes the majority of the load, while the sheet pile transfers the load to the pipe and the surrounding soil. This combination of large diameter pipe piles and steel sheet piles offers a robust solution for various applications, including retaining walls and flood protection systems.
Large diameter steel pipe offers numerous advantages, including strength, durability, and the ability to withstand high loads. Its versatility makes it suitable for a wide range of applications, from structural sections and drilled shaft casing to sign poles, towers, and transmission lines. Whether it’s for supporting bridge structures or creating efficient combination walls, large diameter steel pipe provides the necessary strength and reliability for demanding projects.
