Application experience of gas-thermal aluminum coatings to protect the pipes for underground construction and repair of heat networks

摘要

Questions of sacrificial protection for pipes of underground heat networks with aluminum against the external corrosion are considered. The description of pilot production of pipes with a plasma aluminum coating and the deposition of a sacrificial gas-plasma aluminum coating on weld joints of pipelines and the zone of their thermal influence during assemblage is presented. Examples of repairing the segments of distribution heat networks by the pipes with the tread protection are presented. © 2013 Pleiades Publishing, Inc.
