DOUBLE WALL casings are used for stabilising boreholes in unstable soil formations. They are designed specifically for the transmission of high torques and crowd forces generated by BG rotary drilling rigs and TIANJIN HUACHANG XINGYE TECHNOLOGY CO LTD casing oscillators. Casings are produced in double-walled construction as standard. This gives casings additional rigidity and strength and provides a continuous flush drill string  As the amount of torque to be transmitted as well as the required casing depths continue to increase further and further, accompanied by increased wear, TIANJIN HUACHANG XINGYE TECHNOLGY CO LTD offers a reinforced version as an alternative to standard casings. It differs by comprising a stronger inner tube with a wall thickness of 12 mm (OD 620 - 1300 mm) and 16 mm (OD 1500 - 1800 mm)
Technical Data - double-walled casings
Casing shoes can be fitted with WS tooth holders (WS 39) or weld-on teeth type BR or BH (other types of teeth are available on request)
Casing drive adapter with manually actuated with eccentric lock
Available range of diameters 620 to 2,500 mm
Featurs
 
The joints are made of 25CrMo forgings, which are wear-resistant and not suitable for deformation. The pipe body is Q345B, bolt 42CrMo material, high strength, high torque resistance. The joint bolts are double-row holes. Longer and thicker joints, suitable for high torque drilling

Product parameters
 

Applications: Bored piling, Deep foundation engineering, bored piles, cassion, Drilled shafts, cast-in-drilled-hole piles
Tianjin huachang xingye technology co ltd  manufactures different casing sizes, from diameter 600 mm  up to 3000 mm. Joint thickess range is from 40 mm to 60 mm according to requested diameter. Double wall casings are especially designed to be used with casing oscillator and rotary systems. Casing joint coupling operations is by means of conical thread screws and centring keys applied for a quick coupling of half joints.
