Tubular piles
1.Tubular Piles
Tubular piles are tubular pipes used for piling purposes,which are also called steel piles,piping tubes,or tubular piling. Tubular piles are normally large diameter piles because bigger bending moment are required in lots of cases.
Tubular piling are available in numerous European and US steel grades and can be coated on request and are provided with C9 connectors. Steel piles are the main retaining elements of the combined wall, carrying horizontal loads from soil and water pressures and vertical foundation loads. The intermediary Z-type sheet piles transfer horizontal loads to the tubular piles.Piling tubes are manufactured in a range of materials, from standard carbon steel to high tensile steel, and in all thicknesses to suit specified design. Our piling designs are well proven in quay walls and as the backbones of floating structures. Wider applications include foundation works and construction pipes, industrial pipeline networks, communications infrastructure, and machinery.
The tubular combined wall not only service as the retaining wall member, resisting horizontal loads, but also serve as bearing pile which resist vertical loads. The OZ sheet pile can be shorter than the tubular piles and only have the functions of earth retaining and load transfer. Nowadays the interlocks used in the combined piles have many choices on the market, C9 C14 are the most traditional sheet piling accessory.Further fabrications, like piling shoes,lifting ligs, weld beads, beveled ends, corner sections, paintings...etc we can all do in our workshops.SGS or BV Inspection report is normally supplied.
Our Advantages
Ø With our pipe pile mill strategically located near the port and our strong steel pile production ability, No limit on tubular pile dimensions, This is especially important for deep foundations,quay wall, cofferdam,Jetty construction. The biggest tubular pipes we have produced, length up to 100m,diameter up to 3m.Any steel grade,X70 or S460 or A690,as long as you name it, we will produce for your steel piles. Our SSAW pipe machines can produce up to 25mm thickness pipe piling, our LSAW machines can produce up to 100mm thickness piling pipes.
Ø Our steel piling factory will produce the required sheet piles sizes, and corner sections as well. So that we will ship with tubular piles in one shipment, you just need to install them at jobsites.
Ø Further fabrications, like piling shoes, lifting ligs, weld beads, beveled ends, corner sections, paintings...etc we can all do in our workshops.SGS or BV Inspection report is normally supplied.
Paintings:
Our inhouse painting facilities allows for any kind of anti-corrosion protection: Painting, Petrolatum Tapes, Galvanizing.
Application:
Pipe piles are produced from different steel grade for wide applications, for example, foundation pipes, king pile, monopile, bearing pile, pipe pile wall, slope stabilization, pipelines, deep foundation, and struts etc.

ACCESSORIES
Chill Rings
A chill ring includes a cylindrical non-consumable base metal ring having an outside diameter sized to fit adequately inside the diameter of the pipe end to be welded.
Conical Points
Conical points are used to push the earth aside and maintain grinding. On rough surfaces, the point distributes the load around the entire pipe, rather than focusing the shock on only a section.
Cutting Shoes
A open-end cutting shoe is an exceptionally tough, heat-treated cast steel shoe with a ledge to ease driving. Use of a cutting shoe protects the pipe end and makes it possible to use a thinner pipe.
Pipe Caps
Pipe caps are available in all standard sizes ranging from 8 5/8" to 72".
Pipe Splicers
Pipe piling splicers are available in all pipe sizes. Pipe splicers help ease alignment of pipe and drive it with no welding required.

3. Coating Specifications
Fusion Bonded Epoxy – Fusion Bond Epoxy is a powder epoxy thermosetting coating applied for anticorrosion protection to steel pipelines. The pipe is first blast cleaned and heated. Then epoxy powder is spray applied by electrostatic guns to melt and form a uniform layer that hardens within a minute from application. Utilizing industry accepted materials supplied by manufacturers such as 3M, DuPont, and Valspar, the facility can apply FBE in a wide range of thickness to cost effectively meet any project specifications.
Fusion Bonded Epoxy with Abrasion Resistance Overcoating (FBE/ARO) – Utilizing two completely separate powder systems, the facility can produce FBE with an ARO at unprecedented processing speeds using industry accepted materials such as 3M 6352, DuPont 7-2610, and Lilly 2040.
Fusion Bonded Epoxy with High Temperature Resistant Overcoating – Utilizing two completely separate powder systems, the facility can produce FBE with a high operating temperature resistant overcoating such as DuPont’s Nap-Gard Gold and 3M’s 6258.
Fusion Bonded Epoxy with Zap-Wrap Overcoating – The facility is capable of processing line pipe with connections and of applying the Zap-Wrap abrasion resistance overcoating to the ends of each pipe.
