DOUBLE WALL CASING – Heavy-Duty Foundation Drilling Casing for Maximum Bore Stability
In the world of bored pile foundations, precision and structural integrity are everything. The Double Wall Casing (Bored Pile Machine Spare Parts) is engineered to deliver both. Designed for rotary drilling systems that demand high resistance to pressure and lateral forces, this casing ensures clean boreholes, stabilized walls, and safe excavation—no matter the ground conditions.
As part of 3GEN Export’s OEM-compatible range, the Double Wall Casing meets the highest industrial standards and is compatible with leading bored piling machines, including BAUER, LIEBHERR, SOILMEC, SANY, and XCMG. Produced in Türkiye, trusted worldwide.
The Double Wall Casing is a robust tubular segment designed to protect the borehole walls during drilling operations, especially in unstable or loose soil layers. Unlike single wall systems, the double wall design enhances torsional strength and alignment, making it ideal for deep foundation projects where soil collapse or water ingress are potential risks.
The casing consists of two concentric steel tubes:
Outer tube for structural rigidity
Inner tube for alignment and reinforcement
The interface ring connects the segments securely with high-grade bolts and inserts, ensuring leak-proof and torque-resistant assembly.

This range provides excellent flexibility across different drilling diameters, ensuring a secure, repeatable connection system even under extreme torque and downhole vibration.
Double Wall Structure: Reinforces pipe strength while minimizing deformation and deflection at deeper drilling depths.
Threadless Connection: Bolt-based joint system reduces stress risers and is easier to replace on-site.
Seamless Internal Flow: Smooth inner casing ensures unobstructed passage for drilling fluid and tooling.
Corrosion-Resistant Coating: External yellow powder-coat protects from weathering and rust in aggressive soil or marine conditions.
Custom Machining Available: Casing shoes and drive adapters can be added for rig-specific requirements.
The Double Wall Casing is compatible with a wide range of bored pile machines, including:
BAUER: BG 18, BG 28, BG 36, BG 40
LIEBHERR: LB 20, LB 28, LB 36
SOILMEC: SR-40, SR-65, SR-95
SANY: SR205, SR250, SR360
