海洋钻井隔水管张紧环上壳体焊接工艺研究
Research on Welding Technology of the Upper Cover of Tension Ring for Marine Drilling Risers
摘要
Abstract
To solve the technical problem of integral forging processing for the upper cover of the tension ring of marine drilling riser,welded parts are used instead of integral forgings for the upper cover of the tension ring.The upper cover adopts a thick steel plate welding structure,with T-joints,K-grooves,and CJP welds.By analyzing the specific structure of the upper cover,the welding sequence of the upper cover was reasonably designed.The welding process qualification test was completed using a test plate with a limit plate joint,and the test results met the design requirements.The developed upper cover of the tensioning ring for marine riser can provide a reference for the"welding instead of forging"process of complex structural parts in related marine underwater equipment.关键词
