Segmental casing liners are used in the construction of drilled shaft with the purpose of preventing the collapse of an open-hole. Casing and liners play an important role to guarantee the success of foundation projects.
Segmental casings are made of steel pipe with required length and joined either by welding or by bolting. There are two main types of segmental casings: temporary casings and permanent casings. Both temporary casings and permanent casings serve as the same purpose, the biggest difference between them is the temporary casings are used as a tool that would be removed after the concrete is placed while permanent casings would retain in the place and become a permanent part of a foundation.
Kimdrill can manufacture a series of segmental casings such as double wall casing tube, single wall casing tube and casing tube with slot. Double wall casing tube and single wall casing tube are both have male/ female joint on the end of the tube and joined by bolting. Casing tube with slot are without male/female joint and joined by welding. It’s usually used as permanent casings
Double wall casing tube
It has an outer wall thickness of 10-18mm and an inner wall thickness of 8-12mm varies with the casings size, reinforcing bars are set between the inner and outer wall.In order to increase the strength, we adopt the ring casting alloy steel 25CrMo to produce the casing joint that all undergo heat treat and precisely machined.
Single wall casing tube
It has the single wall thickness vary from 16-30mm and the casing joints thickness of 40-60mm according to the casing size.
Both double wall casing tube and single wall casing tube can be applied to hydraulic rotary drill rig or casing oscillator.
