Long-distance pipeline works continuously for a long time. Therefore, many impurities will accumulate on the pipe wall. This causes the flow rate to decrease. Severe conditions can even lead to corrosion or even blockage. Therefore, regular inspection and cleaning of pipelines are essential. Here we talk about a good tool “Pipeline Pig” for detecting and cleaning long-distance pipelines.
The pipeline cleaning work is completed by the pig. Pigs (also called pipeline pigs) are special tools for cleaning pipelines driven by gas, liquid, or pipeline transmission medium (oil, liquid natural gas). They can remove impurities in crude oil and pipelines in operation. Moreover, it can reduce the corrosion damage to the inner wall of the pipeline. In addition, it can redefine the pipeline route. At the same time, it can detect pipeline deformation. Or we can use it to check the integrity rate of valves along the line. It can also reduce the working back pressure, etc.
The pig moves slowly in the pipe. It arches inside like a pig, and will not turn back. Another reason is that it emits harsh and unpleasant sounds when working. This is similar to the howling of pigs. So people named it Pipeline Pig, which is still used today.
Pigs can be divided into cup type, straight plate type, foam type, buckling detector type, and intelligent type according to their appearance. The lower the crude oil temperature is, the easier the pipeline is to deposit wax. The most common straight plate type pipe pig can remove the wax deposit on the pipe wall.
Then the blue plastic plate is used to remove the sediment on the pipe wall. The black rectangle on the end face is a magnet for removing loose metal objects in the pipe.
The above figure shows a straight plate pipe pig. The blue plastic plate is used to remove the sediment on the pipe wall. The black rectangle on the end face is a magnet used to remove loose metal objects in the pipe.
▲ Foam pig
Solid casting pipe pig, integrated molding. It is usually made of polyurethane
