The cup pig (straight plate pig) has a rigid skeleton and two or more sections of the front and back cup. When running in the tube, it maintains a fixed direction, so it can carry a variety of detectors and devices.
The cup pig (straight plate pig) has a rigid skeleton and two or more sections of the front and back cup. When running in the tube, it maintains a fixed direction.
The main body of the scraper is a steel frame;
Come with 2-4 sealed cups;
An electronic positioning transmitter can be carried.
The sealing performance of the cup pig is good, it can not only push out the liquid in the pipeline but also push out the solid impurity effect is better than the pig ball.
Good sealing property;
Effective running distance is 100-150 miles;
The best running speed is 1-3m/s.
It is applied to pigging before production, cleaning the stones, wood bars, and other matters left in the pipeline;
Cleaning and nitrogen replacement after natural gas lines go into operation. Exhaust before the water pressure test and drainage after the test;
Segregate medium insulation within mixed pipelines.
Size Range: 2″ ~ 64″
Medium Temperature:-40℃~90℃
Elbow curve radius:
R>1.5D(When pipeline nominal diameter>150)
R>2.5D(When pipeline nominal diameter<100)
Equal-diameter T-junction of piping should have a spherical grate. The pipeline’s deformation rate is lower than 10%
The main pipeline should use a ball valve.
Metal or non-metal pipeline that can undertake the pressure after cleaning.
Putting the right directional cover in the flexible compensation parts.
Raw oil, product oil, edible oil, natural gas, LNG, chemical materials, coal water slurry, sewage, running water, etc.
The dish-type leather bowl has better sealing performance, there are deep dishes and shallow dishes, and steel nails can also be added to the leather bowl to increase the cleaning effect.
The steel brush should be interchangeable with the leather bowl, and it has a good cleaning effect on the rust and scale removal of the pipeline in the process of pipeline cleaning.
It uses the skirt of the leather bowl to close the interference of about 3% to 5% of the pipeline and the pipe wall to achieve a seal, and the pig is driven forward by the pressure difference of the natural gas before and after it.
