The invention discloses a liquefied natural gas ship sweeping pump closure pipe mounting method, which comprises the following steps of: splicing a plurality of sections of closure pipes into a whole section of closure pipeline in a liquid cargo tank, then moving the closure pipeline to a jig frame outside the liquid cargo tank, and carrying out welding operation of welding seams on an open field outside the liquid cargo tank. The problem that welding personnel are anoxia and even poisoned due to the fact that folding pipes are welded in a cabin traditionally is effectively solved, and the personal safety of the welding personnel is guaranteed.

    本发明公开了一种液化天然气船扫舱泵合拢管的安装方法,本发明在液货舱内将多段合拢管拼接为一整段合拢管路,然后将合拢管路移至货舱外部的胎架上,在液货舱外部的空旷场地上进行焊缝的焊接作业,有效地解决了传统在舱内焊接合拢管会使焊接人员缺氧甚至中毒的问题,保证了焊接人员的人身安全。
