Friction drill kelly is a type of drill pipe composed of
international advanced six-rib distribution technology. The kelly
generates pressure when the kelly rotates to generate a circular
force, and the rotation transmits the pressure downward to generate
frictional force. Simple operation, drilling depth. It is suitable
for soft soil layer and mud sand layer. The whole set of kelly has
the characteristics of light weight, high strength and high
linearity of a single drill pipe. The inner and outer layers are
reasonably matched with good wear-resistant plates, which greatly
meet the special requirements of the drilling rig.
1. Adopt international advanced six-key power distribution
technology and standard modular design.
2. The whole set of kelly is light in weight, high in strength,
high in single-section straightness, thin in pipe wall, small in
joints between joints, and good in wear resistance of internal and
external keys, which greatly meets the special requirements of
rotary drilling rigs.
3. The material specifications are complete, and the kelly can be
matched with any rotary excavator at home and abroad. All our
kellys are full torque and have a maximum digging depth of 100
meters.
4. Our kelly is made of special customized seamless steel pipes
made of domestic high-quality alloys, and can also be made of
high-strength seamless steel pipes imported from Germany according
to customer requirements. We have 3 types of kelly, interlocking,
friction. and combination. The kelly length depends on the actual
needs of the customer or the parameters of the drilling rig.
