manufacturing accuracy of progressive plate, the scale of plate should adapt to the needs of different pipe diameters to form a serialization. The thickness of the plate varies with the thickness of the structural span, and the plate thickness can be selected 2.5-8mm; Plate waveform: For the stiffness of the progressive plate, the section of the plate is processed from the plate to a wave shape with a certain amplitude, starting from the request for the stiffness of the processing, assembly and plate, and referring to the waveform of similar products at home and abroad. The wavelength of the tube with a diameter of less than 1M is 25mm for 125mmbogao; The wavelength of the tube with a diameter greater than 1 M is 55mm for 200mmbogao.
