Technical design features

Casings, barrel cores, and their nipples for exploratory drilling must meet with GOST 6238-77 standards. Casings and barrel cores can be supplied with or without nipples (core-to-core joints). Where nipples are required for connection, they are engineered with outer threads at both ends, which can be either left or right. Barrel cores are equipped only with right thread.
Threads should be smooth and without defects that could impact strength and continuity. Nothing more than traces left by the thread cutting tool are permitted. Thread centerlines at nipple ends should be in alignment. Decline from true alignment should not be greater than 0.6 mm.

Manufacturing specifications

Barrel core diameters range from 25 mm to 108 mm. Nipple joint casings have a diameter of 73 mm to 146 mm. Casing and barrel core lengths can be manufactured in the range of 0.5 to 6.0 m.

Surfaces should be free of cracks or other defects apart from insignificant blemishes that do not reduce the wall thickness to negative deviation.

Cores and nipples should be manufactured from steel of grades D, K or M with phosphorous and sulfur mass fraction not exceeding 0.045% in either case.

The GOST 632-80 standard regulates manufacture of casing and couplings. Casings are produced in lengths from 9.5 to 13 m. One end of the casing has the screwed coupling and the other end has the drill pipe protector to protects its thread.

Applications for casings and barrel cores

Casings and barrel cores are typically used for these activities:

  • Exploratory drilling projects
  • Construction projects
  • Geotechnical surveying projects
  • Water and mineral exploration

Barrel cores enable core output and input. They also maintain the direction of the drilled well shaft and prevent damage to the walls of the well shaft in unstable terrain and ensure it is isolated.

Payment terms and delivery methods

On receipt of an order, we draft the contract for manufacture, which includes the terms for payment and delivery, including:

  • The deliverables to be manufactured
  • Delivery method

We then issue an invoice, and await payment by the customer.

Production commences once cleared funds have been received and the deliverables are shipped to the customer by the freight forwarder.
