Foam pigging balls are easy to deform, have good passability, and have low risk of pigging. Non-stop production pigging, that is, passing foam pigging balls into the oil and gas pipeline to clean the oil and gas pipeline, is a method of cleaning the oil and gas pipeline by using the pressure difference between the front and rear of the foam pigging ball to move the foam pigging ball in the oil and gas pipeline while maintaining oil and gas transportation. Compared with stoppage pigging, it can reduce the impact on oil and gas production and downstream users, but the foam pigging ball needs to withstand high pressure of oil and gas in the pipe.
