| Specifications︰ | PIPE PILES
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

DSAW Pipe Piling
Double Submerged Arc Weld pipe (DSAW) is created through a welding process in which the welding arc is immersed in flux at the time of welding. Double welds (both inside and outside the pipe) are required to manufacture this pipe, and generally each weld is completed separately. DSAW pipe is normally produced in sizes from 24” through 56” OD and wall thicknesses from .312" through 2".
Spiralweld Pipe
Spiralweld Pipe has a joint running along it's entire length in a spiral form. Due to the manufacturing process, a wide variety of diameters can be produced. The length range is infinite and is determined only by the customer's transportation budget.
SAW PIPE Production Process
Submerged arc welded (SAW) large line pipe derives its name from the stage in the production process wherein the welding arc is submerged in flux while the welding occurs. The flux protects the steel in the weld area from impurities found in the air when heated to welding temperatures. Double submerged arc welded (DSAW) large line pipe requires both inside and outside welds, which are accomplished in separate processes, hence the “double” prefix. DSAW encompasses both longitudinally welded SAW (LSAW) and helical (or spiral) welded SAW (HSAW).
LSAW large line pipe is most often produced using either the pyramid rolls method (also known as the rolled and welded method) or the U&O method (also known as the “U O-E” method). The difference between these two processes exists only in the method of forming the steel cylinder. The pyramid rolls method begins with three rolls arranged in a pyramidal structure, between which the steel plate is pressed until it is formed into a cylinder – the time required depends on the grade and thickness of the plate. In the U&O method, the cylinder is first formed into a U shape using a “U” press, then curled into an O shape (i.e., a cylinder) using an “O” press. Under this method, the “E” in the U-O-E descriptor signifies the press process in which the pipe is trade (or “stitch”) welded until further SAW welding is performed.
Once formed, the cylinder is then welded both from the inside and the outside longitudinally along the length of the cylinder using the SAW process, with up to five welding wires, which in the end results in a welded pipe.
Stages in the LSAW production process typically include: cutting and baiting the steel into strips (“skelp”); pre-bending; forming; stitch and pre-welding; internal and external SAW processing; finishing; straightening; cold expanding (for yield strength); demagnetization; seam removal, and bevelling (depending on the order in question).
HSAW (or “spiralweld”) large line pipe is characterized as a steel pipe having a DSAW seam the entire length of the pipe in a spiral form. HSAW is produced using hot-rolled coil that is formed into a hollow cylinder by twisting the skelp as it is unrolled (in the same manner that the cardboard core in a roll of paper towel is formed) and then welded as the edges come together using an automated SAW process both inside the cylinder and outside the cylinder. The end product is a welded pipe.
Stages in the HSAW production process typically include: de-coiling and leveling; skelp end welding for continuous rolling; edge trimming and bevelling; forming and tack welding; cutting to length; skelp and repair welding; inside cleaning of pipe; internal and external SAW; further inside cleaning; weld seam removal at pipe ends; and beveling of pipe ends.
Both LSAW and HSAW large line pipe production processes also comprise a number of quality control steps including, but not limited to, the following: skelp and edge ultrasonic testing; sampling and destructive testing; inspection of SAW; tack weld inspection; hydrostatic testing; ultrasonic testing; x-ray weld inspection/filmless radiography; final inspection; and generation of certificates. The complainant employs both the LSAW process and the HSAW process for its production of large line pipe.
[35] Using the U&O method, large line pipe is generally produced in 40-foot lengths (commonly known as “double random lengths” or “DRL”). Using the pyramid roll method, however, large line pipe is most often produced in 20-foot lengths (“single random lengths” or “SRL”) or shorter; this may require producers to girth weld multiple sections together to achieve greater lengths, as needed. Using the spiral weld method, large line pipe can be rolled into exact lengths up to approximately 115 feet (including “triple random lengths”/“TRL” of 60 feet and “quadruple random lengths”/”QRL” of 80 feet).

Marine and Jetty Piling
Piling is an essential element of the construction process, regardless of whether the building is taking place on land or offshore. Due to our longstanding experience, we have an unmatched knowledge of the Swan River and its seabed conditions. Our employees have inherited the collective knowledge and experience of over 50 years of construction operations.
WHAT IS PILING?
Piling forms the basis of construction, including marine construction, as it provides the fundamental support needed for any kind of structure to be built. Piling is the procedure of setting deep foundations into the ground, usually using wood, steel or concrete. This creates a robust and stable base for construction to commence.
OFFSHORE PILING
Marine piling is the process of building deep foundations into the ground below sea level to support buildings and structures that are offshore. There is a great level of complexity involved when piling underwater, which is why it’s imperative that only certified professionals undertake marine piling. At Jetty and Marine Constructions, we’re not only licenced and qualified to conduct marine and jetty piling but we’ve also had decades of experience piling in Western Australian waters, meaning we’re very well acquainted with the ground conditions.
OUR MARINE PILING SERVICES:
At Jetty and Marine Constructions, we’re qualified and certified to conduct any marine piling works, this means that we can pile any structures that need to be installed over the water. We offer a range of marine piling services and can customize our piling solutions to fit your construction project needs. Our jetty and marine piling includes:
CHS Piles
I Beams
Concrete Piles
Piles of up to 800mm in diameter
Although we can construct piles for any structure over the water, our most common piling projects include:
New marina floating pontoons
Mooring piles
Fixed jetties
Private jetties
Piles for general anchorage of vessels and other structures
