pipeline pigsPipeline pigs are used to perform maintenance operations inside of pipelines, without stopping the flow within the product pipeline. Used in a multitude of industries and applications, pipeline pigs can often perform their function without causing any downtime. These devices are available in a variety of sizes and configurations and offer an economical solution to many manufacturing requirements, including batching, cleaning, dewatering, and drying. Drinkwater Products carries a full range of pigs and will help you decide which one is right for your job.
