The proven design of the
PolyEurope Decoking Pig removes the hardest coke and encrustations from furnace tubes, plug, box headers and fired heaters. With the ability to negotiate short radius bends and U-bends due their resilience and flexibility, this range of Decoking Pig can be driven by relatively low pressure around 150psi. The tungsten steel studs scrape or break the coke layers loose while the water flows around the pig to create a low / high pressure turbulence. This action flushes loosened deposits from the cleaning studs ahead of the pig.
