Higher Efficiency HDD Drilling Tools - Reamer Bit For Reaming Oil ,
Used to enlarge the pilot hole in Horizontal Directional
Drilling(HDD) - HDD
Hole opener ranging from 12 to 66 that is divided into two types:
MT cutter and TCI cutter, and is used in various compressive
strength of the formations. The product is used for the reaming of
the oil, gas, petrochemical, sewage, power and fiber optic
pipelines in the no-dig horizontal directional drilling.
Directional crossing operation is widely used in unexcavated
project. Three steps in such operation are: 1, oriented hole
operation; 2, hole opening; 3, pipe pulling. Hole opening is the
most onerous task in this operation, but, the key for hole opening
operation is the hole opener choosing according to the operation
equipment and formation.
Small torque force can be applied to hole opening with drilling
Hole opener includes body and the cutter. 4 different types of
cutter can be assembled to the body in one size for opening the
hole in 4 sizes.
Cutter can be divided into MT type used in soft formation and TCI
type used in hard formation. Huanyu Hole opener takes its
advantages in its better teeth distribution,wearing resistance
ability, bigger cutting area and higher efficiency.
Inner and outer anti-drop device are applied in the hole opener to
reduce the dropping accident of cutter under bad drilling
Roller bearing and bigger section are applied in cutter and rubber
seals improving the running life of the hole opener.
Oriented piece on the body for guiding and support , wearing
resistance alloy on the surface improve the ability of wearing
resistance and shock resistance.
