Portable compressed air treatment – removal of water, oil, and particulates – has become a mainstay of our business. An important segment of the portable market includes the construction and maintenance of pipeline infrastructure.
When a new pipeline is constructed it needs to be hydrostatically pressured tested – hydro testing for short – to ensure there are no leaks in weld seams. This involves pressurizing a segment of the new pipeline with water. After successful hydro testing, the pipeline needs to be “de-watered”. This procedure involves pushing and blowing liquid water from the pipeline. Finally humidity – water present in the vapor state – needs to be removed from the pipeline. In the pipeline construction and service industry, this process is often called dew point drying. It requires atmospheric air to be compressed, cooled, filtered, and dried. The high purity compressed air then flows through the pipeline absorbing humidity. Dew point drying prevents premature corrosion of the pipeline and contamination of the product following commissioning.
Van Air Systems’ Prep40 compressed air dryers are specially designed for “pipeline dew point drying” operations. Their rugged components and tight footprint make sense for outdoor service at jobsites that are constantly on the move.
