What are the common reasons for the pig to get stuck in the pipeline?
1. Construction remnants during pipeline construction
The dirt left in the pipeline during pipeline construction caused blockage. This can improve the quality of the project by strengthening construction management and other means. If it is estimated in advance that there are more dirt in the pipeline. Then we can clean the pipeline before the pigging operation.
2. Pipe deformation
Pipeline damage due to construction. Or in the process of pipeline operation, due to various external influences, the pipeline is deformed by force. This thus causes a ball jam accident.
3. Wrong valve selection
According to the requirements of the pigging process. Pipeline valves are full-bore valves. In all types of valves, consider it from a pigging perspective. It is best to choose a ball valve. Because the ball valve operates quickly. Least easy to jam. And the positioning of most ball valves is relatively accurate.
4. The valve is not in the fully open position
Due to incorrect operation or changes in the limit of the actuator, the valve cannot be opened or closed properly. Be sure to check the pipeline valve i before pigging. Make sure the valve] is in the fully open position
