Description
Customized Polyurethane Pig, integrally formed, made of polyurethane. Customized Polyurethane Pig is usually installed on the pipelines including the tool of water, gas, or oil. The stress difference between the front and the rear of the pig presses the pig ahead to ensure that the pipe is cleansed by the pig. Emergency medical technician solid actors pig has the functions of excellent looking appearance, strong wear resistance efficiency, and so on.
Why is pig cleaning required?
Pipeline transportation has the advantages of high economic efficiency, low transportation loss, and long transportation distance. This makes it widely used in oil and gas transportation. However, the dirt generated during the use of the pipeline will block or corrode the inner wall of the pipeline. This will reduce the efficiency of pipeline transportation. Therefore, oil and gas pipelines must be cleaned. The pig is the most commonly used tool for pipeline cleaning.
The polyurethane cup in the pig is interference fit with the oil and gas pipeline. The seal can isolate the front and rear fluid and form a pressure difference. So it can drive the pig to scrape the dirt on the pipe wall. The ability of the pig to scrape dirt on the pipe wall mainly depends on the friction between the cup and the pipeline. Therefore, the pig cup has great wear during pigging. This also directly affects the working performance and service life of the pig.
The cup has two main functions: one is to realize the sealing between the pig and the pipe wall and isolate the fluid at both ends of the pig. They can form a pressure difference to drive the pig forward; Second, it can clean the dirt on the pipe wall and disperse the dirt accumulated at the front end.
Precautions: when the minimum outer diameter of the sealing part is less than the inner diameter of the pipe, the sealing part shall be replaced with a new one.
Storage: stored in a cool and dry place, fireproof and UV aging proof.
