Product description
● El cuerpo de la tubería de perforación adopta la tecnología de procesamiento de la tubería de perforación lisa, y la unión está soldada por tecnología de soldadura por fricción para garantizar la resistencia de la tubería de perforación en sí. La cuchilla en espiral adopta soldadura de doble cara, y la ranura de guía de la cuchilla es profunda, lo que mejora la capacidad de autodescarga y es más adecuada para perforar sin agregar agua. Además, la junta adopta una junta hexagonal, que puede realizar una construcción hacia adelante y hacia atrás y no es fácil de atascar.
