Double Wall Casing Attachment Heat Treatment Casing Driver Shoes

Application:

1. Casing is used to minimize loosening of the soil structure around the pile during the drilling process.The use of casing is compulsory ,if even with a supporting suspension,the ground to be drilled is unstable ,and collaps of the bore hole wall must be expected.

2. Casing tubes have the function of cutting the soil structure with a casing shoe,to support the bore hole temporarily,and by preceding the excavation,to forestall loosening of the ground structure.

Feature

1. The technical parameters and processes of the products are in line with the Bauer standard;

2. Deformation and accuracy is strictly controlled through heat treatment,each casing is interchangeable;

3. BJTUFF casing joints are manufactured from tempered steel.The casing joints with high machining accuracy guarantee a fast replacement and bolting of the casings as well as the best force transmission effect.
