  • Ведущая труба в основном предназначена для передачи крутящего момента и поддержания массы бурильной колоны;
  • Все ведущие трубы укомплектованы штампованным стальным протектором, и поставляет трубы с упаковкой стальной трубы по требованию Заказчика.

Ведущие бурильные трубы (ВБТ) предназначены для передачи крутящего момента ротора на бурильную колонну при бурении скважин.

ВБТ изготавливаются:
К – квадратного сечения
Ш – шестигранного сечения.

Kelly is the drive part of whole drill string, it transmits the torsional energy from the rotary table to the bit in the bottom of the hole. Kelly is supported by the swivel through the rotary table and connected to the first joint of drill pipe in the drill string. Kelly has been approved by the API certification. Straightness is the key manufacturing process. Straightness is checked before, during and after each machining operation. Flats are precision-milled to API specifications. All millings are performed on specially designed rigid Kelly mills. Each Kelly is furnished with a pressed steel thread protector. We supply both square kelly and hexagonal kelly.

  • Kelly is manufactured strictly according to API Spec7-1 standard. Manufactured from AISI 4145H-modified, fully heat-treated alloy steel with aBrinell hardness range of 285-341 and a minimum average Charpy impact value of 40 ft-lbs.
  • The end, drive section and connection of Kelly are machined and inspected according to API standard.
  • Ends and drive sections, IDs and connections machined and inspected to API specifications.
  • Kelly bars are ultrasonically inspected over full length and section.
  • Shipped in a protective steel-cased scabbard.

Kellys are manufactured with one of two drive configurations, square or hexagonal. Square kellys are furnished as forged or machined in the drive section. Hexagonal or fully machined square kellys are machined from full length quenched and tempered round bars.

Square Kelly and hexagonal kellys are fabricated as per requirements of customers. The kellys are made of AISI 4142H-4145H forged or rolled alloy structural steel. Quenching plus tempering thermal treatment will be conducted over the whole length. Its Brinell hardness can reach 285-341 on the basis of such thermal treatment. Charpy impact energy: >or =54J. The formulated process can ensure that the misalignment of the hole reaches the standard wall thickness. Kelly bars are manufactured according to API-7-1 Spec.

Kelly can be:
– Square section;
– Hexagonal section.
