Pipeline cleaners are indispensable in gas pipeline cleaning,Generally, a sealing disk (cup) is used to form a seal with the inner wall of the pipeline. Under the push of the pipeline fluid, it moves forward along the pipeline, scraping out the dirt on the pipeline wall, and pushing the impurities accumulated in the pipeline out of the pipeline, thus achieving the effect of cleaning the pipeline.  Therefore wear and heat resistance is particularly important, which directly affects working life. In addition, if pipeline pig operates under uneven condition, it can cause pig deformed, urethane have enough strength and plasticity to prevent deformation.

For pipeline cleaner we suggest customers to use MDI 3-compoenent system if with this production ability, if not, two component system can be recommended.

Urethane valve is another application in oil gas industry, which is used on oilfield fracturing trucks. Because fracturing trucks can form cracks when operating in underground oil fields, in order to achieve the goal of increasing production. The second fracturing truck has three water inlets and three water outlets. In order for the water outlet to open in the well, it must be sealed with high-pressure resistant rubber.

Because of this crucial working condition, urethane must have the properties of oil resistance, corrosion resistance, wear resistance, etc. And also can afford high pressure. We recommend that special polyol is adopted, and sometimes special isocyanate can be met, like PPDI or NDI.
