AW BW NW HW HWT Casing Advancer For Odex Casing System Durable
Casing Advancer Introduction
Casing Advancer features a simple, yet robust and proven design
comprised of a Pilot Bit, a Casing Shoe and a Heavy-Duty Ring Bit.
It’s a concentric type overburden drilling system, which allows for
the simultaneous advancement of casing as big as 24″ in diameter,
while drilling through fractured rock with a conventional
down-the-hole air hammer. The pilot bit securely locks into the
ring bit via special locking lugs to form the robust
oversized-looking face of a conventional hammer bit – loaded with
premium grade of carbide buttons. The unique locking mechanism also
allows for direct transfer of energy from the hammer to the
drilling surface of the ring bit and the pilot bit, which in turn
ensures a superior penetration rate. The casing pipe is easily
welded to the casing shoe, which threads into the ring bit to sit
unrestricted on its shoulder, thus, preventing the casing pipe from
rotating during the drilling operation and securing it at the same
time. Depending on the drilling application, Drill King
International customizes its casing advance system for either
permanently left in the hole casing or retrieved (pulled-out)
casing. Additional customization options are available based on the
specifics of the drilling project, the actual casing and DTH hammer
used, and the ground formation and conditions.
Casing Advancer Features:
1.Each knife is made of crushed tungsten carbide.
2.To make these cutters more practical, our downhole hydraulic pipe
cutters are designed with fully interchangeable internal
components.
3.In fact, the only difference of various casing cutter assembly is
the size of heavy duty cutter body. This means there are fewer
parts in need of repair and replace. Therefore, you need not to buy
and stock casing cutters' components in order to run and maintain
cutter with multiple sizes.
4. Used for cutting NW casing or HRHP/H/HM rod at any point in a
drill hole when the entire string can not be retrieved.
5. NW, HW, PW PWT Rod box connection.
Operations:
1. Upon lowering the assembly, the cutting lugs are retracted
inside the body by the spring. With low rotation (25 rpm)
initially, the cutting lugs are forced out using water pressure, 1
380 kpa (200 psi). A drop in pressure indicates that the cutting
operation is complete.
2. AW, BW, NW, HW/HWT casing cutter all is available.
3. Stocks is available any time.
