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.
