Product Description

Made from AISI 4145H alloy steel and fully heat treated, all its physical properties conform to the latest API Spec7. Heavy drill pipe is the transition section between ordinary kelly and drill collar. It can relieve the stress concentration of the combination of drill collar and kelly during the transition. Besides, it can provide drill pressure and reduce the linked area of drill stem and side wall, as well as wear rate of OD. There is an upset section in the middle of drill pipe. The drill pipe and joint are welded with cemented carbidehardbanding, which can efficiently keep the pipe from wearing. HWDP can replace drill collar and solve series of problems appearing in the vertical well of softer geological structure. Its advantages are as follows:

lReducing torque in high-rpm or deep drilling.

lBring along the drill collar of stem within less time.

lReducing the tiresome damage of tool-joint connection.

lEasy for the stem's handling and operating

lHelpful for keeping the direction of directional well

Our IHWDP, Shanxi Weigao Integral Heavy Weight Drill Pipe is welded with standard hardbanding on the two ends' joints and middle-upset section.

The sickness of hardbanding is within 1/8" of the abutting surface (it can be increased if needed).
