Heavy drill pipes. General information.
These are hot-rolled thick-walled pipes with annular cross-section. The main purpose of such pipes is to increase rigidity of the lower part of a drill string and to provide additional axial load for a rock destruction tool. The weighted drill pipe can be either smooth or with a tapered bore, the purpose of which is to ensure that the drill pipe is gripped and held in place by a hoist.
Joining
The connection of weighted drill pipes is carried out using pre-drilled tool joints, which have special coarse threads with a significant taper. Tapered threads are much better than cylindrical threads, since the screwing process creates an interference, which ensures a good sealing of the existing joints. To increase the fatigue strength of threaded connections, relief grooves can be turned on them.
Range
Sizes of weighted drill pipes, mm: 120; 133; 146; 178; 203; 219; 229; 245; 254; 273; 299. The weighted drill pipes are made of the following materials:
- - 38KhNZMFA steel;
- - 40XHN2MA steel;
- - 40Kh steel.

Product Label
Each drill pipe set has its own serial number, and all the pipes included in the set have their serial numbers inside the set. All drill pipe lengths are labeled. The marking includes the serial number of the set, strength group, the last digit of the year of pipe introduction into the set, and nominal wall thickness. The marking of steel drill pipe with welded-on tool joints designed for drilling and production applications in the oil andThe marking of steel drill pipes with welded-on tool joints for drilling and production applications in oil and gas industry is conducted in accordance with the requirements of
Marking application
Marking is applied to the inside surface of any metal pipe (distance from pipe end - not more than 16 mm) with internal diameter from 103 to 180 mm. Alphanumeric marking is applied with minimum expenses and in minimum time, in compliance with existing labor safety rules. Marking (fully or partially duplicating the main marking) is applied by automated impact method to the surface of the cone bore (bore) of the Drill Latch Coupling. Marking line text, character width and height, mark point spacing (marking quality) and marking needle impact force are set programmatically using the marker control controller, where they are saved as a unique marking file.
Completed marking operations (files) can be automatically saved in the controller. In addition to the marking text, the date, time, and duration of the operation are stored.
Application
| Type of equipment | Application recommendations |
Drilling tool. Pumping and tubing, casing, drilling, oil and gas and other metallic pipes, couplings and interpreters for pipes and tubular products. Other elements of pipe columns. |
Direct marking in places that make it difficult to damage or remove it during transportation, storage and operation. Note: if the hardness of the metal of which the product is made exceeds 62HRC, the use of laser marking equipment is recommended for reliable marking SICMarking (coordination with the technology departments of tool manufacturers and drilling companies is required). |
| Wellhead equipment of any type and design. Pipe fittings of any type and design. | Marking on metal plates installed in places that make it difficult to use mechanical means of their removal; after installation, the plates are painted in the color of the product body at the place where the plate is installed. |
| ESP (Electric Centrifugal Pump Installation) and USSN (Well Rod Pump Installation) | Direct marking on internal elements and housings of ESP installations, USSHN rods and other structural elements, as well as marking on metal plates installed in places that make it difficult to damage or remove them during transportation, storage and operation; after installation the plates are painted in the color of the product casing at the plate installation location. |
| Pipeline valves of any purpose, type and size made of metals and alloys. | Direct marking on the elements of the valve or on metal plates, with their subsequent installation on the valve. It is recommended to use two-dimensional (2D) DataMatrix-ECC200 type codes - very small size and high capacity (up to 1555 symbols of the Cyrillic alphabet and digits) allow you to use this code as a database containing any information about the valve. |
