Pipe piles is a structural building material used to support and stabilize a building's foundation. When the soil below a building is loosely packed, it may not offer enough strength to keep the building stable over time. A pipe piling can be used to distribute the weight of the building deeper into the earth, where the soil is often more tightly packed. Pipe piles are also used to support exceptionally large or heavy buildings, where even standard soil cannot offer adequate support. Finally, a pipe piling may be required when the land area is too small to accommodate spread footers or foundations, forcing buildings to dig deeper to achieve sufficient ground stability.
Engineers and installers determine the placement for each pipe pile based on the building loads at various locations. A very heavy load, such as a piece of industrial equipment, may need to sit directly over a pile to ensure adequate support. When building loads are evenly distributed, installers may use a concrete pile cap to support the building. This allows the pipe pilings to be equally spaced below the building, then connected together with the pile cap to act as a large foundation system.
Piles are driven into the ground using large machines known as pile drivers. These machines contain hydraulic systems which exert extremely high levels of force to drive the piles into the ground. By driving the piles directly into the soil without drilling holes first, the soil itself helps to support and stabilize the piles. As the pile is driven underground, the soil is displaced, which increases friction and pressure around the pile to hold it in place.
Pipe Piles have been used extensively as foundation piles for power stations, high-rise buildings, civil engineering works, bridges, marine structures, harbours, etc.
Each pipe piling must be carefully chosen based on building forces, soil conditions and local building codes. A geotechnical engineer can test the soil to determine whether piles are needed. The structural engineer then determines the size and material needed for each pipe piling, as well as the required depth. When a single pipe is not long enough to reach this depth, piles may be joined together using butt welds or splicing sleeves
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.

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 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.
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 are available in all standard sizes ranging from 8 5/8" to 72".
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.

For quay-wall construction of ports, in tunnels or river crossings combi-walls are used as retaining walls. The system consists of tubular piles (King Piles) equipped with connectors (named also interlocks, locking bars or clutches) compatible with U or Z type infill sheet piles. Sheet piles that transfer the pressure of the main loads to the King piles are connected with E21 / C6 or E22 / C9 interlocks welded on both sides. Spiral pipes present the advantage of long lengths without circular welds and resistance against buckling. Other combi-walls (pipe to pipe systems) with different connectors can also be supplied. Coating of the splash zone with a paint system might be more economical than steel wall increase for corriosion allowance. The stability of the wall against operational loads (port cranes, stacked container loads…) can be ensured with the use of tye rods attaching the quay wall to an anchor wall made of shorter tubulars or double sheet piles
Combi-wall A Combi-wall is a combination of large-diameter steel pipe piles and sheet piles installed to form a retaining wall structure. Pipe piles provide resistance to overturning forces and the steel sheet piles serve as in-fill between the pipes. Combi-walls can be left in place permanently or elements can be extracted and re-used when no longer needed.
The pipe pile portion of a Combi-wall is typically installed as a bored pile which may or may not be backfilled with concrete and reinforcing steel, depending on the application. Sheet piles are installed in the spaces between the pipes with a vibratory hammer and are aligned with pipes using welded interlocking points. Other pile cross-sections such as H-piles can also be combined with sheet piles to form a Combi-wall.
Combi-walls provide a cost-effective shoring alternative to the secant wall while providing significantly more load bearing capacity than a sheet pile wall.
Combi-walls are effective in temporary applications as the steel elements can be easily removed and re-used once the structure is no longer needed.
