he difference between the diameter of SSAW steel pipe and the outer diameter of pipe joint is greater than the height of square steel bracket in the middle layer; the height of square bottom bracket is higher than the height of the highest square steel bracket; the height of the middle layer of square steel bracket in the bottom is higher than the height of square steel bracket; the spiral pipe mill is in the same layer, and the adjacent ends of two steel pipe bit joints are staggered and arranged along the longitudinal direction of the drill pipe; in two adjacent steel pipes, along The longitudinal direction of the drill pipe is arranged with two objects that are far away from each other at the end of the connecting rod of the upper and lower drill pipes; the outer diameter of the poor thing's drill pipe joint and the steel pipe drill pipe is larger than the height of the highest square steel bracket.


The packaging comprises the top bracket, the bottom of the middle layer and square steel bracket, the bolt of the intermediate adapter, the lower part of the nursing block, the supporting sleeve, the end part and the lower part of the nursing block. The packaging supporting structure of the invention is simple, the carrying capacity is large, the transportation cost is reduced, and the productivity is improved.
