Pipeline Maintenance - Pigging
Pipeline Pigging Technology "Pigs" was originally developed and utilized to remove the debris or material build-up which obstructed or restricted flow through a pipeline. Pipeline "pigging" is loosely defined as the propelling of a projectile (the pipeline cleaning pig) through a pipeline to push the contents out. Pipeline Pigging Technology is utilized to flush out debris and build-up, scrape and clean the interior pipe walls, and "batch" various products through a piping system. The pipeline maintenance procedure is performed during new construction and pipeline repair or modification. Pipeline Pigging Technology is also essential in areas of de-commissioning, abandonment and subsequent removal of pipelines. Typically the industry uses four basic types of pipeline cleaning pigs: polyurethane foam pipeline cleaning pigs, mandrel or mechanical pipeline cleaning pigs, solid cast urethane pipeline cleaning pigs, and high tech "smart pipeline cleaning pigs". The most common of them is the versatile "poly pipeline cleaning pig" which is thrust through the pipeline by hydraulic or pneumatic pressure to clean the interior walls, remove debris and flush liquids from the pipeline. Whatever the reason for flow interruption or restriction, pigging is the preferred method for improving the flow and restoring the pipeline to its required capacities. Pipeline Pigging Technology is cost efficient, very effective and environmentally friendly. More importantly, it is a viable and economical alternative to pipeline replacement.

Product Recovery
In every production process or transfer system, there is the possibility of product loss or contamination. There are variations in the direction and elevation of piping systems that trap costly product in portions of these pipes. Furthermore, cross-contamination can occur when a different product is introduced in a subsequent run. Therefore, a good product recovery system is valuable to the bottom line. Flow-Line Services understands plants with typical piping systems are faced with loss of product, waste surcharges, diluted product and cross-contamination. Subsequently, Flow-Line Services also provides fabrication, consultation and sales of "Product Recovery Systems” and the special pipeline cleaning pigs utilized in these systems. The use of these pipeline cleaning pigs following a transfer of product, ensures maximum retrieval of usable raw or blended materials that otherwise would remain in the pipeline, and be lost or contaminated. Maximum product recovery reduces the volume of water, solvents or other material used in line cleaning and/or sanitation. Related disposal costs and cleaning time between batches are also minimized.
