Двойная колонковая труба, в которой внутренняя труба соединена с внешней трубой с помощью шарикового и/или роликового подшипника, позволяет увеличить жесткость внутренней трубы и предотвратить ее вращение вместе с внешней трубой. Извлекающее устройство и внутренняя стенка трубы имеют антифрикционное покрытие. Набор стабилизирующих элементов распределен вдоль внешней трубы для стабилизации внутренней трубы. Конический башмак внутренней трубы имеет нижнюю скошенную кромку. Колонковая труба включает индикатор заклинивания керна во внутренней трубе и уплотнительный узел с шариком, обеспечивающий уплотнение внутренней трубы колонкового устройства.A double core tube, in which the inner tube is connected to the outer tube by means of a ball and / or roller bearing, makes it possible to increase the rigidity of the inner tube and prevent its rotation together with the outer tube. The removal device and the inner wall of the pipe have an anti-friction coating. A set of stabilizing elements is distributed along the outer tube to stabilize the inner tube. The conical shoe of the inner tube has a lower beveled edge. The core tube includes a core jamming indicator in the inner tube and a ball seal assembly that seals the core tube inner tube.
