Inaccessibility or absence of legitimate devoted pig/scrubber launcher and collector offices might cause a pipeline that is customarily acknowledged as piggable to be viewed as non-piggable.

Ordinary pigging strategies and innovation are not appropriate for such frameworks.

HOW TO PIG NON PIGGABLE LINES?

The best or ideal pipeline for pigging is when the following conditions are met

• A straight pipeline
• A uniformly round internal diameter without any change in wall thickness and weld penetration
• Internal surface is polished
• No valves or offtakes

In reality all of these conditions are rarely met and in certain cases none are met.

In certain cases if proper considerations are not taken into account then the line can be completely unpiggable.
