Steel structure tubular string can be specified according to size

BBN produces steel structure tubular string in a variety of specifications. In terms of diameter, the larger is 2500mm, the smaller is 316mm. In terms of wall thickness, it is 25mm and 6.5mm
During the construction period, the steel structure tubular string can be selected from a variety of specifications according to the actual stress situation, so as to give full play to the strength of the steel pipe column and meet the requirements of the project for safety and economy.
Strong bearing capacity at this stage, the steel pipe used in the construction of low carbon steel, the material in shear strength, tensile, compressive and other aspects of the ability are strong, and after processing the formation of steel pipe, its high level in bending, suitable for the geological environment of strong bearing layer application, so that its mechanical characteristics can be fully play, to optimize the single pile bearing capacity, Reduce the size of foundation cap, reduce the total pile.
BBN steel structure tubular string is easy to adjust the pile length, improve economic benefits of each section of steel structure tubular string of the conventional length of 6m, through welding long, if the buried depth of the holding layer changes, can be combined with the situation of pile for welding or cutting treatment, in addition to the steel structure tubular string excised part can also be used in welding other steel pipe column, to avoid the waste of resources, In addition, the design elevation of pile top can be accurately controlled, which is conducive to the construction work.
