Product Details

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 grades are DZ50,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.
