Drilling equipment is used for drilling and construction of this specific conditions of the mechanical devices and equipment, divided into drilling equipment and Drilling tools two categories. Drilling equipment mainly by drilling rig, mud pump and mud purification equipment, mud mixer, drilling tower and other components,and drling tools includes driling pipe, adapter/kelly and collar.
Friction Welding Drill Pipe and adapter
Friction welding Drill Pipe and adapter are in accordance with API SPEC 5DP and SY/T5561-2008 Specifications.The steel grade are DZ250,R780,G105,S135 that are after partly or overall heat treatment.The adapter part adopts thermal refining to superior alloy steel 35CrMo or 4137H that`s after thread hardening treatment and phosphating to better antiseize.It also can be produced upon customers` requirements.
