Master's Thesis Civil and Constructional Engineering BYG508 - University of Agder 2019 Based on the results from pre-projectand workcovered by this thesis, no better alternatives to AISI 4130 material was found, neither could it be safely concluded for removal of NACE MR0175/ISO 15156 requirementsin any parts of high-pressure drilling fluid system. SinceAISI 4130 hasshown to be the optimal choice for the system,it was decided to look forimprovementsof welding procedure by optimization ofpost weld heat treatmentforthis steel.Heat treatment is an expansive and time-consuming procedure that,if not done correctly,could weaken the materialand jeopardize the safetyof the system.Inthis thesis, whi…
