Abstract
A pipeline pig is provided having a restricted fluid bypass channel which serves to bring fluid from the back of the pig to its front, the fluid agitating and suspending discrete solids such as sand or rust, or commingling with scraped paraffinic and asphaltic deposits accumulated by the pig as it moves through the line, thereby preventing the buildup of a solid bed or plug of sufficient thickness or viscosity in front of the pig so as to cause the pig to partially collapse and ride over it or to become stuck.
