Plusfab - Open End Pipe Pile
Open-end pipe piles have no sealed bottom or welded pile tip; the inside of the pipe is open during construction. Soil can naturally penetrate the pipe, creating excellent side friction resistance. If end bearing is required, concrete or grout can be poured after cleaning the borehole. This design works well in soft soil, silt, and reclaimed areas. It offers low resistance to penetration, quick pile driving, and stable bearing capacity. We primarily provide foundation work for projects such as ports, docks, offshore platforms, bridge foundations, deep foundation pit support, and large logistics facilities.
Commonly used steels for open-end pipe piles are Q345, Q355, Q420, API 5L Gr. B, X42, X52, and X60.
The default surface color is black. We can also offer anti-corrosion treatments. Options include painting, epoxy, zinc-rich primer, 3PE, and hot-dip galvanizing, depending on the project. For coastal or offshore projects, we generally recommend heavy-duty anti-corrosion treatment.
Basic components: A pile includes the steel pipe body, welds, reinforcing rings, guide rings, and flange connections. We can also add specialized connectors, reinforcing plates, pile caps, and hole-cleaning tools per your drawings.
When we deliver, we will include material certificates, weld reports, dimension sheets, and anti-corrosion records.
- The open design allows for faster pile driving with less resistance, especially in soft soil, silt, and reclaimed areas where there is almost no rebound.
- Friction is naturally generated between the pipe wall and the internal soil, resulting in very stable bearing capacity.
- Simple structure, convenient transportation and installation, and a good balance between cost and performance.
- We can also produce large-diameter, thick-walled piles, which are particularly suitable for offshore engineering or deep foundation pit projects.
- Port structures, wharf engineering, offshore platforms
- Bridge foundations, deep foundation pit support
- Large logistics terminals, municipal engineering, coastal retaining walls
- Soft soil layers, silt layers, reclaimed areas (open-type structures offer the most significant advantages)
- Offshore projects requiring resistance to tides, waves, and impacts
- Chemical composition, mechanical properties, and thickness tolerances are checked from the moment the steel plates arrive at the factory.
- The entire weld process undergoes UT/RT/MT inspection, with 100% flaw detection when necessary.
- The thickness of the anti-corrosion layer, straightness, and end structure are all strictly measured.
- Each batch has a material certificate, weld report, dimensional record, and anti-corrosion report.
Our factory makes large-diameter, thick-walled open piles. We offer a one-stop service for welding, beveling, stiffening rings, flanges, and corrosion protection. This means you won’t need to find multiple suppliers.
We offer stable delivery times, complete documentation, and extensive experience in customized offshore/bridge projects.
Our engineering team can assist you with drawing review, provide construction advice, and develop solutions.
After-sales service is also excellent; we offer consistent support to long-term clients.
