Polyurethane foam pig features and main uses
Polyurethane foam pig is made of polyurethane material coated on the foam core. It is a new type of pig that develops rapidly and has wide application. Due to the large amount of deformation, light and soft, it is not easy to jam in the pipeline. At present, it has been expanded and applied to various types of pipeline pigging operations in various industries. So what are the characteristics of polyurethane foam pigs? What is the main purpose? Let's take a look at it together.
Polyurethane foam pigs are available in glossy, spiral or integral steel versions with densities from 20 Kg/m to 3160 Kg/m3. The basic type has a density of 20 Kg/m3 to 40 Kg/m3. Polyurethane foam pigs are made from molds and can be supplied in series and small diameter intervals to facilitate the removal of thick and hard scales.
The polyurethane foam pig can be fitted with a high performance positioning transmitter to indicate position and health in the pipeline. When the pig is jammed, it can rely on the high deformation property of the polyurethane foam pig to pass or press to rupture the body and unblock the pipe by itself. After the pressure is broken, if a high-performance positioning transmitter is installed, the position of the obstacle in the pipeline can be accurately indicated.
Characteristics of polyurethane foam pigs
1. Adding a high-performance positioning transmitter is beneficial to quickly find the jam or broken position;
2. the use is simple and convenient, low cost, large deformation, strong ability to pass; ◇ steel hard foam type can be used to remove hard scale;
When a jam occurs, increase the pressure to crush it and unblock the tube.
Polyurethane foam pig main use
1. Before the pipeline is put into production, the pipeline is cleaned and the residue in the pipeline is removed to make the pipeline unimpeded;
2. The gas pipeline is regularly dewatered;
3. The oil and gas pipelines are regularly treated with wax to ensure the maximum transport capacity of the pipeline;
4. The pigging operation for thick and hard scale pipelines.
5. Used for experimental pass when the internal condition of the pipeline is unknown;
The above is about the characteristics and main uses of polyurethane foam pigs. I hope everyone can understand the characteristics and main uses of polyurethane foam pigs.
