Product Description
Description
Pigs are supporting equipment for pipeline cleaning. Pigs for Pipeline Cleaning are driven by gas, liquid, or pipeline transmission medium. It can carry other auxiliary equipment to complete various complex pipeline operations. Without pigging technology, it is impossible to carry out pipeline construction and operation. Only pigs can accomplish a lot of work economically. Therefore, pipeline technology and pigging technology are inseparable.
Disc pigs are widely used in petroleum, chemical industry, gas, water transportation, printing and dyeing, food, and other fields. It is necessary special equipment for pipeline construction, cleaning, maintenance, protection, detection, and management. Using pigging valves and cooperating with corresponding pigs can more easily complete the work of pipeline cleaning, emptying, isolation, and orderly transmission of media. During pigging operation, it can be used only by connecting the air compressor to the launcher. Its disadvantage is poor sealing. Once gas leaks from the gap between the pig and the inner wall of the pipeline, the back pressure immediately decreases significantly. At this time, the pig may stagnate.
In some cases, two-way moving pigs are used. A flat elastic disc larger than the pipe diameter is installed on the two-way pig, which has good sealing performance on either side. or equally bad. The sealing performance of a two-way pig is not as good as that of a one-way pig, nor is the running interval of a one-way pig long.
Purging of Gas Pipeline by Disc Pig:
Gas purging or pigging ball cleaning shall be selected for pipeline purging according to the following requirements: nodular cast iron pipes, polyethylene pipes, steel skeleton polyethylene composite pipes, and steel pipes with a nominal diameter less than 100mm or length less than 100m can be purged by gas. Pigging balls should be used to clean steel pipelines with a nominal diameter greater than or equal to 100mm. The purging of gas pipelines shall meet the following requirements: purging shall be carried out in the order of main pipes, branch pipes, and courtyard pipes, and the purged dirt shall not enter the qualified pipelines. The pressure regulator, valve, orifice plate, filter screen, gas meter, and other equipment in the purging pipe section shall not participate in the purging, and the device shall be reset after the purging is qualified.
