Soft Rocks Drilling Roller Cone Bits IADC437 Seled Bearing ndi Long TC Insert Bits

IADC437 tricone roller bits ili ndi zoyikapo zazitali za tungsten carbide zomwe zimayenera kubowola miyala yofewa kwambiri.

Miyala yofewa nthawi zonse imakhala yodzaza ndi nyimbo zomata zomwe zimakwirira mano zomwe zimapangitsa kuti pang'onopang'ono.

Zoyikapo zazifupi za tungsten carbide zimatha kubowola miyala yolimba mosavuta, koma sizingabowole miyala yofewa komanso yomata, kupukuta pang'ono kumalepheretsa kuti miyala isathyoke.
IADC437 ndiyotalika TC imayika ma roller cone bits, ndiyoyenera kubowola mapangidwe ofewa mwachangu.
