Abstract: | |
Pigging operation is a highly risk work, the pipeline pigs may be stuck, lead to leakage accident, and even lead to fire and explosive hazard. In addition to the possible risks in natural gas pipeline pigging, it may appear some other risks in sour gas pigging operation which increases the risk of pigging operation. In line with the specific implementation flow of pigging operation, risks in the process of pig launching, operating and receiving are analyzed in detail, to guarantee the workers’ safe, and ensure the pigging operation be smoothly completed. |
