Discussion on the definition of flow velocity in the outlet pipe of acetylene compressors
Thread Content
A question about the acetylene flow rate. According to HG/T20570-95, the flow rate of acetylene gas is specified with reference to the design standards for acetylene stations in GB50031-91. However, if the acetylene gas comes out of the compressor and is transported to the workshop (at a pressure of around 0.6 MPa), then which standard should be applied for determining this flow rate (the maximum flow rate)? Should it be in accordance with GB50031-91 or HG/20570-95, for gas compressor discharge pipes where P＜1MPa (table value), at a velocity of 10-8 m/s?
The range for 20570 is somewhat wider; it is recommended to design it in accordance with the standards for acetylene stations. Additionally, the scope of application is specified on the first page of the acetylene station design specifications; I’m not sure what purpose your acetylene is being used for
Acetylene is used as the reaction gas, with a reaction pressure of 0.4 MPa, which exceeds the high-pressure limit specified in the design specifications for acetylene stations. .
