DFP S-1800

No-weld splicers for pipe piles
DFP S-1800 Splicer for pipe is a smooth outside TUFLOY casting that is tapered each way from a center ledge to create a tight drive fit that does not require any welding. If welding is required the splicer is supplied without a taper, slipped on and welded in advance. Driving is done on the splicer. The S-1800 also cuts costs and speeds installation by eliminating delays caused by butt welding pipe piles, and eases alignment in vertical and batter piles.

Strong point closure for pipe piles
DFP's P-77 is a extremely high strength point in a non ribbed configuration that flush fits to the end of the pile for easy attachment, by using a simple groove weld around the top of the point.  The P-77's  TUFLOY composition makes it a very strong casting for practically any soil condition you may encounter. The P-77's smooth 60°  cone and flush configuration make it an ideal point for pipe piles. For closed end pipe, a conical point is the preferred closure. It drives straight; it molds and pushes the earth aside so friction is maintained; and in many soils it drives faster and develops friction resistance at less depth. The P-77 is designed for fast, easy attachment to the pre beveled pipe.  The P-77 has a heavy bottom that can take hard driving,  plus the side walls are also thickened for added strength.  This in conjunction with the low alloy steel makes the P-77 an extremely strong driving point.

Flat cast steel no-weld closure for pipe piles
DFP PB-170 Drive Boots for pipe pile closure replace flat plates with a TUFLOY tapered NO WELD cast unit that can be tapped on a pipe and dragged to the driver at a minimum overall cost for material and field labor. It is self aligning for straight conformity with the pipe. In conjunction with DFP's S-1800 Splicer sleeve, it eliminates the need for an on site welder and material waste by making use of pile cut-offs. The PB-170 has a ribbed bottom that adds strength and resists sliding on a sloping surface.

Protection for open end pipe piles
DFP O-140 Cutting Shoes for open end pipe bring the strength of TUFLOY cast steel to protection of pipe with assurance of dependability. Cutting shoes may be outside flanged to keep the interior clear to remove obstructions and cut a socket. With an inside flange a smooth outside preserves maximum friction. DFP can supply cast steel cutting shoes up to 36 inches in diameter. For larger diameter pipe, DFP can supply high strength rolled and weld rings. They can be made to fit over the pipe or the preferred method is to make heavy rings that would butt weld to the end of the pipe.

Extend pipe with low cost shell
DFP also makes transition splicers from pipe to lower cost shell and different sizes or materials for other piles as a specialty item. This splice is generally used to extend mandrel driven shell piles beyond the length of the mandrel. The DFP B-11 splicers can be made for pipe to shell of different sizes.  DFP has a similar splicer with wedges for connecting shell or pipe to a driven timber pile. Be sure to ask DFP for devices to meet any need.

Precision engineered, easiest fit-up ever
DFP weld ring spacers (also known as chill rings) enable the ring to be automatically centered in the joint without tacking the ring to the the pipe ID., thereby allowing consistent time saving in positive fit-up and aligning pipe. The diameter of the spacers provides the correct root gap required for complete weld penetration. DFP offers many styles of spacers, please inquire when ordering. Be sure to mention wall thickness, as rings are made to order.

High quality, reusable, easy fit-up and removal
DFP now makes stamped steel pipe pile safety covers.  DFP pile covers when properly secured provide the driven piles on your jobsite with a protection level not provided by other types of covers. DFP covers are easy for a workmen to install onto the piles and easier to remove (because of the flared rim on the bottom).  They also keep out debris and will prevents costly accidents.  They are normally supplied unpainted, but can be painted on request (and additional cost).  Be sure to mention the pipe diameter when you call.
