Complete blade assemblies and individual blades are available for Super Pigs in sizes from 14" to 60". The blades and assemblies are manufactured from the same LN-10 urethane as other Super Pig components. Blades are used to successfully remove paraffin buildup in oil pipelines and to aid in the removal of compressor sludge in natural gas pipelines. Blade assemblies can be custom tailored to meet special requirements. S.U.N. Engineering, Inc., also manufactures blades to fit other manufacturer’s steel mandrel pipeline pigs.
