Alternating Current Corrosion of Aluminium Sacrificial Anodes
(Master thesis, 2013)Direct Electric Heating (DEH) is applied to subsea oil production and transmission pipelines to prevent freezing of hydrates as wax during productions shut downs. To prevent clogging, the pipes are heated by application ... -
Alternating Current Corrosion of Aluminum
(Master thesis, 2015)Formation of wax and hydrates due to production stops is a well-known problem in the oil industry. Conventionally the pipelines are heated beyond a critical temperature to avoid this problem. This is done by a method called ... -
Alternating Current Corrosion of Carbon Steel
(Master thesis, 2011)The objective was to investigate if the established theory concerning corrosion calculations and electrochemical behavior of carbon is valid when steel is exposed to AC in an electrolyte consisting of 3,5 wt% NaCl and ... -
Alternating Current Corrosion of Steel in Seawater
(Master thesis, 2015)A challenge regarding the transportation of oil and gas in pipelines subsea is to keep the temperature high enough to avoid formation of wax and hydrates, which eventually will stop the flow. In 2000, Nexans introduced a ... -
