Process For Commissioning Pipelines
US Patent:
5027842, Jul 2, 1991
Filed:
Sep 11, 1990
Appl. No.:
7/580776
Inventors:
Marvin D. Powers - Houston TX
International Classification:
137, 137, 137
US Classification:
137 1
Abstract:
A process for commissioning pipelines is disclosed which more safely, reliably and ecomonically establishes product purity in the line and reduces the possibilities of structural damage to the pipeline. These advantages are achieved through the use of a specially adapted portable heating system. The system is capable of safely heating petrochemical products in a controlled manner and at rates sufficient to provide adequate input flows of commisioning product whose temperature is adjusted to be substantially the same as that of the nitrogen being displaced from the pipeline that is being commissioned.
Pipeline Cleaning Pig
US Patent:
4016620, Apr 12, 1977
Filed:
May 22, 1975
Appl. No.:
5/580109
Inventors:
Marvin D. Powers - Houston TX
Assignee:
Pipeline Dehydrators, Inc. - Houston TX
International Classification:
B08B 904
US Classification:
1510406R
Abstract:
This invention provides a pig adapted for cleaning material from the inner wall of a pipeline and for assisting in the removal of this material from the pipeline. The pig comprises a cylindrical, open cell foam core. An impervious jacket covers the outer wall of the core. An opening in at least one end wall allows the pressurized fluid inside the pipeline to permeate the core. An abrasive means completely covers the outer cylindrical surface of the jacket. The abrasive means preferably is a layer of hardened steel bristles attached to a web backing. The tips of the steel bristles are bent in a longitudinal plane in the direction of travel of the pig.
