Trenchless Horizental Drilling Replaceable HOB Hole Opener
Introduction
The specifications of pangolin hob hole openers range from 16" to
70", and are divided into two types: MT knife and welding knife,
which are suitable for various compressive strength of the
formation. This product is used for the reaming of oil, natural
gas, petrochemical, sewage, power and fiber optic pipelines in
trenchless horizontal directional drilling.
Larger bearings and smaller conventional tools significantly extend
downhole service life. Interchangeable cutters are set in TCI and
milling gear styles to match your shaping. All drill bits have 3-6
tools and can open 3 holes of different sizes.
Features
The unique multi-stage anti-disengagement interlocking device
prevents the hob from tripping when the drill bit is empty, and
prevents the hob shell from falling off when the bearing is
damaged.
The roller body is inlaid with a large-diameter hard alloy, which
has a good rock-breaking effect; the bearing diameter is large, and
the impact resistance is strong; the metal seal is used, and the
service life is long.
Advantages
The replaceable hob hole opener is forged from high-quality alloy
steel with good weldability. After modulation, the tensile strength
is high, which can meet the tensile requirements of large-tonnage
drilling rigs. The connection between the wheel body and the valve
body is reliable, and the loading and unloading are convenient, and
no large-scale special hydraulic equipment is needed. A manual
wrench is enough, which is convenient for on-site replacement.
