The manufacture of ventilation pipe is generally realized at the installation site.
通风管道的制作与安装，首先应设计图纸，根据现场情况布置通风管道走向。通风管道施工前，施工单位应与设计人员协商，协调通风风管与其它管线管路位置走向。施工中应与土建及其他专业工种相互配合。通风风管制作与安装所用的板材、型材，以及其他主要成品材料，应符合设计及相关产品国家现行标准的规定，材料进场应按国家现行有关铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件
For the production and installation of ventilation pipes, the drawings
shall be designed first, and the direction of ventilation pipes shall be
arranged according to the site conditions. Before the construction of
the ventilation pipe, the construction unit shall consult with the
designer to coordinate the position and direction of the ventilation
pipe and other pipelines. During construction, it shall cooperate with
civil engineering and other professional types of work. The plates,
profiles and other main finished materials used in the production and
installation of ventilation duct shall comply with the provisions of the
current national standards for design and related products, and the
materials shall be accepted according to the current national standards
when entering the site. According to the site conditions, one way to
install the ventilation pipes is to make all the ventilation pipes on
the ground, then connect them into one piece, and then place them in
place by hoisting. Another method is to place the ventilation pipe
section by section on the bracket and connect them one by one. The
installation sequence is generally main pipe first, then branch pipe.
The riser is generally installed from the bottom up. After installation
in place, the leveling and alignment shall be carried out to meet the
requirements specified in the design.
