Casing
Casing is designed to reinforce vertical, directional, and horizontal oil, gas, and gas condensate wells both under conventional and complex geological conditions.
In manufacturing, pipes undergo multi-step quality control as required by manufacturing standards (GOST 31446-2017, GOST 632-80, API Spec 5CT, local specifications, etc.)
Pipe Fabrication
101.6 to 426 mm
5.21 - 13.8 mm
- Each joint undergoes 100% automated weld and whole-body ultrasonic inspection and hydrotesting.
- The weld is subjected to annealing and has the same strength as the rest of the pipe body.
- High grade material undergoes whole-body heat treatment.
- Casing OD may be protected with a weather coating (upon request).
- All joints are color-coded and stamped as per the requirements of current standards and regulations.
- Casing is delivered with protective covers for pin and box end threads.
- Upon request, the manufacturer is able to deliver casing with special finish and non-standard thread as per GOST 31446.
- Upon request, we are able to deliver casing with special-bevel couplings to improve the friction coefficient as the casing string is threaded through the annular space.
101.6 to 273 mm
5.20 - 16.5 mm
- Pipe is delivered with protective covers for pin and box end threads.
- Upon request, pipes may be delivered with a special finish and a non-standard threaded connection
- Upon request, pipes may be delivered with a special coupling bevel and coupling
- Pipes are manufactured with an exterior weather coting for protection in transit and in storage
377 to 820 mm
245 to 530 mm
- Connection types: threaded, flanged, welded
- Thermal casing is designed to prevent wellheads from sawing in permafrost areas
508 to 762 mm
7.0 - 38.1 mm
