1.The use, working principle, features and application scope of the machine
HKKJ - 25.4/3048 steel pipe end expander is special equipment for spiral submerged arc welded pipe production line. And it is used for expanding the end of pipe so that the diameter and roundness of a certain length pipe end in the permitted range. After expending the pipe is more convenient for the job site. At the same time this way reduces the cost and the labor intensity of the construction personnel. The most important thing is improve the working efficiency.
Machine features: Compact structure, new model, the strength and stiffness is large enough. At the same time the anti-collision device is designed in the end of the module.
Machine using range: Can finishing the enlargement of pipe and ring which is in accordance with API standard. To reach the requirement of the specified precision, the geometry size is controlled by circumference measurement.
Fully considering the characteristics of online equipments of oil steel pipe production line, the design of the machine is simple and convenient for operation. The necessary adjustment only happens when change the pipe size. The rest of operation is controlled automatically.
