we can supply heavy weight drill pipe (hwdp), integral hwdp from 31/2 to 6-5/8. Also we can supply friction welded hwdp, which is assembled with aisi 1340 steel pipe and aisi 4145h or 4137h tool joints. Hardbanding type include arnco 100xt/150xt/300xt350xt arnco series, duraband and tcs series. Internal coating services include tc2000, tc2000p and tc2000ss as customer needs.

features:

the material element of sulphur and phosphorus are strictly controlled in the pipe body and tool joints during the steel making process, which makes the material with high physical properties.

heat treatment must be uniform and deep enough to ensure required physical properties full length, especially in the critical sections of the connection and weld zone.

the drill pipe undergo a full-length inspection especially the inspections on weld neck and upset region.

the thread is the most important factor for drill pipes. All threads would be machined with cnc lathes and inspected with related thread gauges in conformance with api specification. All threads would be phosphated or copperized and the roots are cold rolled to improve the resistance of galling during initial break-in and drilling operation.

we can provide many types of hardbanding including arnco 100xt/150xt/300xt350xt arnco series, duraband and tcs series. We can provide high-end coating services include tc2000, tc2000p and tc2000ss as customer needs.

we can supply integral hwdp from 3 1/2"to 6-5/8". also we can supply friction welded hwdp, which is assembled with aisi 1340 steel pipe and aisi 4145h or 4137h tool joints. hardbanding type include arnco 100xt/150xt/300xt350xt arnco series, duraband and tcs series. internal coating services include tc2000, tc2000p and tc2000ss as customer needs.

orchid energy co hwdp(heavy weight drill pipe) is manufactured by a new wall-thick steel pipe. the two ends and middle of pipe have thickness joints and upsetting. have the function of drill collar and drill pipe. since the transition from the drill collar to the drill pipe, section drastic changes, bending stress concentration in this part of the drill pipe. therefore hwdp between drill collar and drill pipe can mitigate the section changes, reduce the stress concentration, so as to reduce the drilling accident. in addition, compared with the drill collar, hwdp have many advantages such as easy salvage , shorten tripping time, easy handling, have an effect on steady oblique. in condition of hook load and same drilling pressure, hwdp can improve the ability of deep drilling rig. hwdp has been widely used in vertical and inclined well.

Lifting sub is the special tools for lifting of the drill tools in petroleum, natural gas industry and geologicexploration.

Lifting subs are one-piece construction and manufactured from 4145M or 4140HT alloy steel. The Lift Sub can bedivided into sloping shoulder (18 degree) and straight shoulder (90 degree), All lifting subs are complied with API standard.
