Pipe Piling

Pipe piling has been growing in popularity and implementation by leaps and bounds since the late 1980s. A series of exhaustive tests were able to demonstrate how effective pipe piling is in load bearing, and thus use of pipe piling in the civil construction industry boomed. If your industry involves heavy loads or deep foundation structures, you need to know about pipe piling. This overview will explain the basics of how piling works and how it can be optimized for best results in civil construction and deep foundations.

Pipe piles are a simple, easy to understand type of piling. A prebuilt steel pipe structure is driven into the ground, typically with large impact hammers. The piles remain in place primarily through friction with the soil. The pile designs will vary depending on the ground conditions and support expectations, enabling the pile systems to be adapted to any specific needs. Because they are made of steel, they can handle extremely heavy loads, and the right steels can make them virtually impervious to environmental conditions. Different options also allow clients to get the most effective materials for any pipe piles.

Foundation Pipe piling

Foundation pipe piling are needed when soil and ground conditions are not suitable to support the structure to be built upon. Pipe piling are normally used in deep foundations to transfer the structure load to rock formations or to stronger soil conditions deep beneath the ground. We have the ability to cut and splice various diameters and wall thicknesses of carbon pipe piling to accommodate the specific load requirements of these structures. We also have the ability to fabricate piling lengths up to + or – 93 feet and to attach plates, shoes or conical points as required. We offer mechanical & torch cut ends as “Bevel x Square” or “Bevel x Bevel”. Our welders are AWS D1.1 certified to accommodate most marine piling, bridge piling or building pipe piling requirements.

If you work within building construction, offshore / marine construction or bridge construction alongside contractors performing pipe piling driving, please count on us for your pipe piling supply.

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.

STRUCTURAL STEEL SHAPE | Pipe Piling

Steel Pipe Piles are also designed to transfer structural loads through the foundation to soils below. Where H-Piles are typically classified as point bearing, Pipe Piles are most efficient as friction piles. Pipe Piles have substantial surface area that interacts with the surrounding soil to provide great frictional load resistance.

Pipe Piles are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.

ERW Pipe Piling

Electric Resistance Weld (ERW) pipe is manufactured through individual sheets or from rolls of skelp.

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.

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.

What is Pipe Piling?

Pipe piling 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.

Most forms of pipe piling consist of heavy-duty steel pipes, which are often galvanized with zinc to increase moisture and corrosion-resistance. When only a standard level of support is required, an open-ended pipe is often used. If additional support is required, these pipes may be capped with steel plates to form close-ended pilings. Installers can then fill the pipe with concrete and rebar to add extra strength and stability.

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.

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.

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.

Wind versus oil: The pipe piles up in Lincoln County

As Lincoln County residents gathered in Canton Tuesday night to talk wind energy, the sun was setting nearby on miles of steel pipe piling up for a far more traditional sort of energy project.

The pipe sits less than a mile off the Worthing exit on Interstate 29, on land leased from Ron Albers by the owners of the Dakota Access pipeline.

Dakota Access would move North Dakota crude 1,134 miles, from the Bakken Oil patch to Patoka, Ill.

If it’s approved, of course. It hasn’t been.

The Public Utilities Commission has until Dec. 15, 2015 – one year from the date Dakota Access applied for a permit – to deny or grant the pipeline permission to lay 272 miles of the underground line in South Dakota. The evidentiary hearing on the matter will take place in September.

The oil would flow under northern Lincoln County, so plenty of landowners have a keen interest in the project.

Lincoln County resident Paul Zeeb called Tuesday, as I was driving to Canton for a wind farm hearing, to ask about the pipe pile. If miles of pipe sits ready to use on a farmer’s land near the pipeline route, he said, how can anyone have confidence that the PUC is truly weighing the matter?

“In all fairness, if we’re having hearings and we really have a say in it, why are they stockpiling pipe?” Zeeb asked.

It’s a question that’s come up in other contexts, as well. Landowners along the pipeline route have been paid easements already, with some taking deals before the pipeline was docketed on Dec. 15.

Albers told me Tuesday his land was leased Dec. 10, and pipe began to arrive in January.

Joey Mahmoud, an executive with Energy Transfer Partners, addressed the question of pre-permitting costs in January at a packed PUC public comment meeting.

If the pipeline project fails to get permitted, Mahmoud said, the easement money won’t come back to the company. The costs are sunk, just like the costs for pipe, environmental impact studies, surveying, engineering and public relations.

The work’s ongoing. Just a few days ago, Dakota Access filed some slight changes to the pipeline route, some of which were based on input from the January meetings in Sioux Falls and around the state. The pipeline path was moved further away from the Sioux Falls landfill, for example.

The contrast is stark between Dakota Access – backed by the Fortune 100 company Energy Transfer Partners – and the plan of the local investor-driven Dakota Power Community Wind. Zeeb’s question, given the context and the timing, really puts that into perspective.

Essentially, the crude oil pipeline is a big enough investment and a sure enough deal that the company can spend millions on easements and pipe before even getting a permit.

The company’s fact sheet says it will offer $47 million in easements to South Dakota landowners. If it fails to get a permit, that money’s gone.

The pipeline is fighting a well-organized opposition in hopes of gaining a permit for a permanent pipeline, but it’s doing so with the confidence of a proven product with a guaranteed market and a bankroll to match. It’s also clear that the company’s experience and strength in lobbying and permitting far outstrips the experience of the groups opposed to the project, as well.

So that’s the pipeline. Let’s talk about the wind project.

Dakota Power Community Wind is making deals with landowners that don’t pay much until the wind turbines are placed.

Right now, they’re looking at permits to build five test towers that would determine how much wind capacity there is, a process that could take three to five years. Only then, if the investors are convinced and willing to pay, would turbines be built.

Test tower landowners get a one-time, $1,000 payment. The 100-odd landowners who’ve signed up for options will get $100 a year until the turbines are built. If the turbines are built, they get 4 percent of the gross revenue.

If Dakota Wind had more money, it might spend more, but it doesn’t. Dakota Wind’s project developer Rob Johnson says the wind farm’s raised about $2.5 million so far. That’s barely enough for a single turbine.

The wind farm is fighting a well-organized opposition in hopes of gaining temporary permits, doing so to prove the value of a product (turbines) it’s barely raised enough money to build even one of. The project and its backers have worked on wind projects in South Dakota, but they’re essentially locals facing off against locals.

If the pipeline is built, of course, no one will see it. If the wind turbines are built, they would be a blight or a beauty, depending on your perspective.

For the next few months, at least, the pipeline’s the visible one.

Pipe Piling

In recent years, offshore deepwater dock project has been massively constructed at home. As a major deep-water pier pile bearing capacity, spiral weld large diameter steel pipe piles and straight seam steel pipe commonly used. In addition, bridges, roads and high-rise buildings also need pipe piling.

Pipe weld surface shall not have cracks, broken arc, craters and holes and other defects. Presence of the defective welds allow welding, grinding or repair defects allowed. Butt weld steel pipe can be steel belt. Steel allows two pipe sections butt together. Butt welding can use submerged arc welding or manual welding process.

Pipe piling’s main production process is mainly double submerged arc welding technology. The first advantage is fully automated. The second advantage, which is carried out under the submerged arc welding, so it’s the heat exchange and protection of relatively strong performance, high quality welding out. The third advantage, because of submerged arc welding arc welding flux buried underneath, it can use high-current, high welding efficiency.
