Abstract:

Disclosed is a pig receiver for capturing a pipeline pig as it is discharged or ejected from the pipeline. The receiver is readily attachable, detachable and portable. The receiver includes a webbed conduit made of flexible webbing. The webbed conduit includes a passageway having a diameter approximately equal to the diameter of the pipeline to which it is attached. The webbed conduit includes longitudinally extending webbings having loops formed in the webbing ends. The receiver is attached to the pipeline flange by a chain disposed through the webbing loops and is secured around the pipeline by a padlock or other fastener. The unattached ends of the longitudinal webbings are drawn together and secured by a closure, preferably a clevis which is disposed through the loops in the unattached ends of the longitudinal webbings.
