Specification
Steel pipe piles are either welded, spiral-welded, or seamless steel pipes. They are used for deep foundations and for transferring loads from buildings and other structures to deep, underground soil layers. They help resist load pressure by allowing for point bearing and skin friction. Steel tube piles are driven into place with plates or points and may be close-ended or open-ended. Some pipe piles, helical pipe piles are filled with concrete to maximize strength and load bearing capabilities. Sometimes Steel pipe piles that are larger and thicker are a more cost-effective option than filling smaller, thinner piles with concrete.
Features:
1. Large vertical-bearing capacity
By driving the pipe piles into firm bearing layers, they exhibit a large vertical-bearing capacity.
2. High bending strength
Steel pipe piles with high stiffness and high bending strength enable resistance to considerable horizontal force during earthquakes.
3. Excellent environmental performance
Piles with small section areas realize less earth removal and low vibration and noise.
4. Custom fit for each structure
Various pile lengths, diameters, and thicknesses contribute to economical design.
5. Easy production of longer piles and jointing piles
Longer products can be manufactured, and, as joining piles by welding is also easy, it is possible to apply these to deep water and deep underground structures.
6. Easy jointing with superstructures
Jointing with upper concrete structures is easy, using reinforcing steel bars at the top of piles.
7. Easy handling
Steel that’s light and tough contributes to easy handling and transport.
Advantages:
As opposed to other options for deep foundations, pipe piles offer several advantages. They lower costs because they are capable of being tailored to meet specific load bearing requirements. They are simple to drive and install, and they’re easy to inspect and test before use. They are sturdy and unlikely to crack or otherwise get damaged while they are being driven into the ground. Additionally, pipe piles can be added to bolster foundation support after construction and during various phases of construction.
Applications:
Pipe piles can be used for the creation of the following:
• Building foundations
• Bridge foundations
• Highway foundations
• Marine structure foundations
• Dock foundations
• Offshore construction foundations
• Railway foundations
• Oilfield construction foundations
• Communication tower foundations
• Column foundations
These are just some of the examples of possible applications for pipe piles. They are useful whenever a structure or building is large and heavy. They are also excellent to employ in areas where soil quality is poor or only allows for shallow depths unless piles are driven deep into the ground. For marine applications, pipe piles are a great choice to provide extra foundation support in the ocean floor or canal floor.
Installation Methods For Piling Pipes:
Piling pipes are installed in two primary ways: by driving piles or by drilling piles deeply into the ground. Each of these primary approaches can be accomplished by utilizing a variety of various procedures, depending on the type of Piling pipe utilized and the circumstances surrounding the installation.
- Driving Piles
Pile driving is a technique used to install piles into the ground. Pile driving involves using a pile driver to hammer the piles into the ground. It is often used in construction projects, such as building bridges and houses. Piling pipes can be driven into the ground through soil, sand, or rock. The force of the blow from the hammer drives the pile into the ground. The size of the pile and the type of soil will determine how deep the pile can be driven. In some cases, piles may need to be driven into bedrock. Pile driving is an efficient way to install piles in a short period. The technique is often used when traditional excavating methods are not possible or would be too expensive.
- Drilling Piles
Drilling piles are a construction method in which a piling pipe is installed underground. The piling pipe is made of steel, and its diameter is generally big. There are three types of drilling piles: end bearing piles, friction piles, and compaction piles. Drilling pile is mainly used to support the foundation of a building or other structure. It can also be used to stabilize the soil or sand below the foundation. In some cases, drilling piles can also be used to protect the foundation from water damage. When installed properly, drilling piles can provide a strong and sturdy foundation for any building or structure.
Process
The manufacturing of Pipe Piling is a testament to engineering precision. These pipes can be produced through:
SMLS (Seamless): Crafted from hollowed-out steel billets without any welding, offering exceptional strength.
ERW (Electric Resistance Welded): Formed from steel plates welded using electric resistance.
LSAW (Longitudinally Submerged Arc Welded): Produced by welding steel plates longitudinally.
SSAW (Spiral Submerged Arc Welded): Crafted by welding steel plates in a spiral direction.
