Oil Drill Pipe

Shandong Yibin Machinery can provide various specifications of oil drill pipe, mainly in line API 5DP of the drill pipe and conform Oil standard drill pipe. The drill pipe can be equipped with the same grade of drill pipe joints according to the customer’s requirements, and the manufactured drill pipe joints meet API SPEC 7-1Standard. Advanced Oil Drill Pipe Friction Right. The welding production line can adjust the welding parameters to the best position to ensure the quality of the welding belt; the heat treatment process of simultaneous cooling inside and outside makes the mechanical properties more uniform and stable. Equipped with automatic length measuring and weighing, automatic spray mark recording application, to ensure product traceability. Advanced drill pipe thickening and heat treatment production line. CNC tube body full length heating furnace, quenching machine, tempering furnace. Advanced heat treatment process and precise temperature control ensure the mechanical properties of the pipe body. The pipe body hydraulic straightening machine ensures the straightness of the pipe body and the coaxiality of the pipe body.
