Abstract

See full text

An annular seal for a conduit pig includes an annular diaphragm and a separate lead support structure. The annular diaphragm is devoid of internal supports and therefore quite flexible. However, the lead support structure supports the annular diaphragm such that a piston effect can be generated through the annular seal. A brush portion for a conduit pig may include forwardly raked bristles.
