After purification, the acetylene will be pressurized by acetylene compressor (C101) and removed moisture content by acetylene dryer (A101), and then sent into pipe network for the next process.
For improving need assembling the casing head, the cutting casing pipe on project, we have designed the device of cutting casing head to change unfavorable factors using acetylene gas to cut case.
