Drill pipe

1. Own American MTI inertial friction welding machine to ensure welding quality;

2. The advanced technology of using high-power collecting coils to narrow the heat-affected zone, and the heat treatment process of cooling both inside and outside, make the friction welding zone mechanical properties uniform and stable, the weld beautiful and beautiful, and prolong the service life of the drill pipe;

3. The annual production capacity can reach 20,000 tons, and the mechanical properties of various series of drill pipes are higher than the requirements of API standards.

Drill Collar

1. The horizontal drill collar production line uses an intermediate frequency inductor to heat the workpiece, and is controlled by a PLC program controller, which can quench and temper heavy pipe or shaft parts such as drill collars and weighted drill pipes;

2. The types that can be produced include alloy steel drill collars, non-magnetic drill collars, spiral drill collars, and drill collars with elevator grooves and slip grooves;

3. The currently produced drill collars of ø120.7, ø158.8, ø165.1, ø177.8, ø203.2, ø209.6, ø228.6, ø241.3 and other types of drill collars have stable quality and reliable performance.

Heavy drill pipe

1. Heavy weight drill pipes can be divided into integral type and friction welding type weighted drill pipes according to different processing methods;

2. According to the length, it can be divided into type Ⅰ and type Ⅱ;

3. The heavier drill pipe can be processed with spiral grooves according to customer requirements.
