Why blank pipes win
Laser-welded casing strings: monolithic strength and gas-tight reliability at a fraction of the cost.
Major cost savings
Major cost savings
Blank pipes are 15% to over 200% less cost than conventional casing pipes with couplings.
Perfect wellbore seal
Perfect wellbore seal
Dramatically improves cementing quality due to sleek unified strings with no geometric obstructions.
Reduce diameter of well section
Reduce diameter of well section
Change the well diameter by reduction of drilling section. Savings on excavation, drilling fluid, and cement volumes.
Reduction of operational risks
Reduction of operational risks
A smooth, coupling-free design minimizes sticking and allows the string to be rotated to resolve issues.
Traditional threaded joint
Real-world applications
Engineered for safety
Eliminated human operational risks
Automated process removes manual error and the risk of thread unreliability, ensuring wellbore integrity and uninterrupted running
Certified components
Every part of the system is manufactured and tested to the highest safety standards
Controlled environment welding
The extreme-temperature weld zone is hermetically sealed within the operational chamber featuring labyrinth seals, preventing any hot particles from escaping
Uncompromising safety assurance
TongWELD is certified for Zone 1 hazardous area applications
Fully enclosed process
an inert atmosphere is maintained, preventing the formation of explosive gas mixtures

Ability to cut the casing string during retrieval
In the rare event of an insurmountable problem during running, the string may require retrieval and disassembly.
In such cases, the unit’s welding head can be swapped for a cutting head in just 10 to 15 minutes, enabling the pipe to be cut 20–30 mm from the weld.
The precision of the cut allows for immediate re-welding at the cut end, with no additional preparation required.
