Steel pipe piling is also called steel pipe piling,steel pipe pile, Steel Pile , Pipe Pile, Hollow pipe

Steel pipe piling materials: GR.B, GR2, GR3, CC60, CC70,  ST52, S235JR, S355JR etc.

Steel pipe piling standard</strong>: API 5L, ASTM A53, A515, A672, A500, A252, EN10255 etc.

Steel pipe piling specification:

Steel pipe piling outer diameter: 8”-100” (219mm-2540mm).

Steel pipe piling wall thickness: 8mm-60mm.

Steel pipe piling are commonly used for major bridge foundations due to their stiffness and available size range. Pipe piles can be fabricated from a variety of materials, including extruded or rolled thin-walled pipe, spiral welded steel, extruded steel, and rolled steel. The most common type of pipe pile is the ASTM A252, which is made from welded and seamless steel pipe. The wall thickness of the pipe can be increased to increase the stiffness of the pile, making it ideal for use in bridge foundations. Pipe piles are also relatively easy to install, making them a popular choice for foundation work.

Standard of steel pipe piling

Steel pipe piling are made up of hot-rolled coiled steel using a double-sided submerged arc welding method. The welding process allows steel pipe manufacturers to produce large-diameter steel pipes suitable for different applications.

INSTALLATION METHODS FOR STEEL PIPE PIling

Application of steel piling pipe

Steel piling pipes are used as deep foundation piles for power stations, high-rise buildings, civil engineering construction, bridges, marine structures, harbors, and other industries & applications.

Application of pipe piles to reinforce the head of cast cast-in-place concrete pile.

Advantages of steel pipe piling:

The outstanding advantage of steel pipe pile is impressive tough support for underground foundations. Specially When the structure has to be supported for a large load, there is a mandatory requirement for the foundation to be deep and strong. Hence, it is crucial to have the right structural support in place for deep foundations.

There are plenty of options available for structural support. However, the best recommended would be steel pile pipe, owing to the high level of customization that they offer. They can be customized based on the specific requirement and the costs involved are also minimal.

What is a steel pipe piling?

Steel pipe piles are composed of steel pipes, tongue grooves and tongue and groove pins. The pipe wall at the left end of the diameter of the steel pipe is vertically connected to the grooves. The cross section of the grooves is a square shape with one side open. There are reinforcing ribs on the side of the steel pipe, and a grooved pin is vertically connected on the right end of the diameter of the steel pipe and at the radial position, and the groove section of the grooved pin is I-shaped.

When the utility model is used in the cofferdam, the steel pipe piles overlap each other in an arc or circle shape. It can play the role of surrounding water, surrounding soil and surrounding sand. The tongue and groove steel pipe pile of the utility model has the advantages of novel design, simple structure, convenient use, easy lap joint and good sealing performance. Including non-circular cross-sectional profile, constant wall thickness, variable wall thickness, variable diameter and wall thickness along the length direction, symmetrical and asymmetric cross-section, etc. Such as square, rectangle, cone, trapezoid, spiral tube, etc.
