Specifications︰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".

Pipe piles made from 3-ROLLER BENDING PROCESS can have wall thicknesses up to 100mm which makes them suitable for heavy structural purposes, and are commonly used for legs on offshore installations. There are however, manufacturing limitations on lengths ranging from 2.0m to 12.5m, so multiple splices are required for structural and piping applications.

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.

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).


ACCESSORIES | Pipe Piling


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.

Pipe piles made from UOE or JCOE pipe can have wall thicknesses up to 80mm which makes them suitable for heavy structural purposes, and are commonly used for legs on offshore installations. There are however, manufacturing limitations on lengths ranging from 2.0m to 12.5m, so multiple splices are required for structural and piping applications.
