There are always gaps and it is possible to eliminate them when loading. Even if there are some gaps will not affect the bearing capacity of simplified. In order to avoid bad longitudinal welding quality affecting the strength, the longitudinal welds of each layer should be staggered an Angle, so that the overall strength of the cylinder body will not be obviously affected. Safety holes should be opened on each tube section in case of staggered longitudinal joints of laminates. Japanese HD automatic dressing mechanical harmonic reducer SHD-17-50-2SH this hole can make the gas in the interlayer gap at work due to temperature rise and discharge, can also be when the internal leakage can be discharged through the hole, for monitoring.

China has been used to using no. 20 boiler with low carbon, low strength and good welding performance since the successful trial production of multi-layer wrapped high pressure vessel for many years. Japanese HD automatic bandaging mechanical harmonic reducer SHD-17-50-2SH summed up layer plate bandaging structure has the following characteristics: (1) the supply of raw materials is convenient, do not need thick plate only thin plate, quality than thick plate is easy to meet the requirements
