After finishing above work, we can install some outfittings in subsection item, general situation:aircondition duct, stainless duct galvanized duct, duct support, the other ventilation outfitting before vertical loading the block of hull and joining of fabricated section. 各分段通风管安装应根据相应分段风管安装图，风管（支架）加工零件图和材料清单来组织安装，检查风管等附件标高是否与图纸相符，甲板舱壁上开孔是否符合要求。 Installing duct in every block should be reference for duct installation drawing, support manufacturing drawing, part list. Check the quality of duct。 insure hole on the hull correctly 风管支架定位 → 风管定位（通风附件） → 风管连接密封 Place support→install duct(outfitting) →connect duct ●风管支架安装是风管安装的第一道工序。 支架形式应根据风管截面大小及分段具体情况选择，但必须符合设计图纸或国家标准。 风管支架无特殊要求时，应符合以下要求： Installing support is the first step of duct installation. According to area of duct or site situation and GB, to choose which type of the duct. If no special reqirements of duct, we must obey these rules: 水平安装的矩行风管长边小于 400mm，其支架间距不超过 3m，大于或等于 400mm，其支架间距不超过 2m。 If longer side＜ 400mm(horizontal installation), the distance of support＜ 3 m。 If longer side＞ 400mm(horizontal installation), the distance of support＜ 2 m。 垂直安装的风管支架间距为 3m，并在每根立管上设置不少于两个固定件。 If the distance of support ＞ 3m(vertical installation), each duct should have more than two support. 风管支架定位应根据风管安装标高来定，对于矩形风管，它有风管上标高和下标高两种标高；圆形风管是以风管中心作为标高尺寸。 The position of duct supporter shall be positioned according to installation elevation, refer to the rectangle air duct which has upper elevation and low elevation of air duct, the center of circle air duct can as the elevation. 风管支架吊杆通常焊接在横梁或扶强材上，如焊接在甲板上时应 加复板。 Supports are usually welded on beam or construction but if welded on deck, plus pound plate. ……千锤百炼，军工品质 —— 永昇中央空调…… PAGE 17 船用空调通风系统安装施工工艺规范 注意： 30000 吨多用途船的吊架要求带复板并热镀锌处理 Note: The hanger for 30,000T multipurpose vessel shall be provided with pound plate and shall be hot galvanized. ●风管安装： Connect installation 施工现场具备安装条件时，应将预制加工好的风管和附件按照安装图顺序和不同系统运至现场，风管和附件应按照系统图顺序编号，并按编号顺序进行安装。 风管连接 Connect duct 风管安装应按照安装图要求进行，风管安装都在分段内安装，风管之间和风管与附件之间连接大多采用法兰连接，连接的法兰与法兰之间应垫上一层阻燃橡胶垫两圈直径5mm 密封橡胶绳；也有用套管连接和对接焊连接形式，如下图。 另外在分段与分段之间设有合拢管，合拢管应在分段合拢后才可安装连接。 Duct should be installed according to installation drawing, mostly the duct install in block, connect by flange, the 5mm rubber rope between each duct。 or thimble joint and welding joint.
