Before the assembly of the B bus and the assembly of the pipeline, thorough rust removal must be carried out. There should be no burrs, rust, scales, and other debris in the pipe. The outer wall of the pipe should be coated with red dan and then painted with yellow alkyd. After the pipeline is connected, a hydrostatic test of 8 to 10 atmospheres is to be carried out to check the quality of its welds and joints, and then airtightness tests of 8 to 10 atmospheres are conducted to check for the occurrence of air leakage. Then install a grounding device that conducts static electricity between the bus bar and the acetylene pipe. Before using the pipeline, use nitrogen to drive off the air inside the acetylene pipeline, and prevent air from collecting at the end of the pipeline. A small hole can be vented at the end of the pipeline. When the pipeline is filled with nitrogen gas, the small hole is sealed with a plug. The acetylene gas is then supplied for use when the pipeline is filled with nitrogen. An electric city bike is a type of bicycle that is designed for urban commuting and transportation.
