DFP S-1800
No-weld splicers for
pipe
piles
DFP S-1800 Splicer for pipe
piles is a smooth outside fit TUFLOY ASTM A 148 Grade 90/60
casting that is tapered each way from a heavy center ledge to create a tight
drive fit that does not require any welding. The splicer is slipped on the
driven piles while the next length is picked up, speeding production. This also eases pile alignment
in both vertical and batter piles. If welding is required the splicer can be supplied without
a taper, then slipped on and welded in advance. Driving is then done
on the splicer. The S-1800
also cuts costs and speeds
installation by eliminating delays caused by butt welding pipe piles.
DFP P-77
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 ASTM A 148 Grade 90/60
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 thickened for extra added strength. This in conjunction with the TUFLOY ASTM A 148 Grade 90/60 low allow steel makes the P-77 an extremely strong driving point.
Protection for open end
pipe
piles
DFP
O-140 Cutting Shoes for open end pipe
bring
the strength of TUFLOY ASTM A 148 Grade 90/60 cast
steel to protection of pipe with the assurance of dependability. DFP's cutting
shoes
are outside flanged to keep the interior clear to remove
all obstructions
and cut a socket. The O-140 cast steel shoe is designed with a ledge for driving rather than depending on welds in shear to maintain contact with the pipe. DFP can
supply TUFLOY ASTM A 148 Grade 90/60 cast steel cutting shoes up to 36 inches in diameter. For larger
diameter pipe, DFP can
also supply high strength rolled and welded 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.
Precision engineered,
easiest
fit-up ever
DFP weld rings with
spacers (also known as chill rings) enable the ring to be automatically centered
in the joint without tacking the ring to 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. The chill ring works like a backing bar in groove welding and becomes a part of the welded joint. DFP offers many styles of spacers,
please inquire when ordering. Be sure to mention wall thickness, as rings are
made to order.
DFP Pile Covers
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 job site 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.
