ZQ162-50Ⅱ,ZQ203-100Ⅱ,ZQ203-125Ⅱ, ZQ216-135 II Z
ZQ drill pipe power tong is an ideal well head
tool for oil well drilling,widely applied for making-up and
breaking-out in offshore and onshore drilling operations and
workover operations.Open-throat design of the ZQ series allows the
tongs to escape from drilling pipe freely with high mobility.The
tong is a combination of spinning tong and torque tong It
substitutes cathead,manual tong and rotary rope in making-up and
breaking-out. The tongs are designed and manufactured accord- ing
to API Spec 7K“Specification for Drilling and well servicing
Equipment".
ZQ203-125 power tong is our new developed product lt is equipped
with an auto-door. Hydraulic and pneumatic combination control
system performs joint control on gripping operation,door open &
close,and moving operation.lt is national patented product.
