Here is the technical breakdown of the casing specifications, coupling mechanics, and rig compatibility: 1. Casing Dimensions & Tool Clearance For a standard 1500mm double-wall casing, the dimensions typically fall into one of two profiles depending on whether you are running  (CA-DW series) or premium aftermarket casing lines: Specification Profile A Profile B (Heavy-Duty Aftermarket) Outer Diameter (OD) 1500 mm 1500 mm Inner Diameter (ID) 1420 mm 1400 mm Total Wall Thickness 40 mm 50 mm Wall Configuration 18mm outer / 10mm inner + ribs 20mm outer / 10mm inner + ribs Max Tool Diameter 1390 mm (Auger / Bucket) 1350 mm (Auger / Bucket) Standard Lengths 1.0m, 2.0m, 3.0m, 4.0m, 5.0m, 6.0m 1.0m, 2.0m, 3.0m, 4.0m 2. Forged Joint & Coupling Mechanics High-torque rigs like the LB 28 require premium forged joints (male/female rings machined from high-strength forged steel like 25CrMo4 or 42CrMo4) to withstand both the torsional forces of the rotary drive and the high crowd/pull forces. Connection Type: Typically features a conical sleeve/bolt connection system (Bauer or Liebherr standard compatibility). Locking Hardware: Utilizes a 12-bolt configuration per joint layout around the circumference. The joint is secured using conical bolts, matching threaded rings, and locating keys to prevent loose tolerances during oscillation or rotation. Torque Transfer: Forged joints ensure even stress distribution across the casing string, minimizing the risk of wall deformation when the LB 28 applies maximum crowd pressure or when paired with a casing oscillator. 3. Liebherr-LB 28 Rig Compatibility The LB 28 is well-suited to handle this specific casing size due to its structural and hydraulic capacities: Torque Capacity: Equipped with the BA 280 rotary drive, the LB 28 delivers up to 280-297 kNm of torque, providing ample power to cut and rotate a 1500mm casing string through dense or cohesive soils. Crowd Force: The rig's rope crowd system provides up to 400 kN of push/pull force, ensuring effective installation and casing extraction. Drive Adaptability: The casing string connects directly to the rotary table using a 1500mm Casing Driver Adapter (Twister) attached to the BA 280 cardanic joint. It can also be seamlessly integrated if your project requires an external casing oscillator tianjin huachang xingye technology co ltd Double wall сasing: diameter 600-2000mm with walls thickness 40-50mm. Length 1m,2m,3m,4m,5m,6m Designed for drilling with drived by casing oscillator or a rig rotary system. Connections   conical thread screws and centring keys. double wall casing pipe/Single wall casing Our double wall casing have two type joint , one is forge joint:materials is 25CrMO,another type is roll joint Casing joints and pipes for pile protection of collapsing. Casing joints are composed of one male half joint and one female joint welded at each end of casing pipe for easy pipe connection.
