结合实际情况进行检查复核，再按编号进行排列，风管系统的各部分尺寸和角度确确无误后，即开始风管组对工作。风管各管段之间的连接采用法兰连接，接口处要求严密不漏风。一次吊装风管的长度要根据建筑物的条件，风管的壁厚，吊装方法和吊装机具配备情况确定，组对好的风管可把两端的法兰做为基准点，以中间法兰为测点，拉线测量风管的连接是否平直，偏差大时要进行调整

Based on the actual situation, conduct inspection and review, and then arrange according to the number. Once the dimensions and angles of each part of the air duct system are confirmed to be correct, the air duct assembly work begins. The connection between each section of the air duct adopts flange connection, and the interface must be tight and air tight. The length of the air duct to be lifted at a time should be determined based on the conditions of the building, the wall thickness of the air duct, the lifting method, and the allocation of lifting equipment. The assembled air duct can use the flanges at both ends as reference points, and the middle flange as the measuring point. Pull a line to measure whether the connection of the air duct is straight, and adjust it when there is a large deviation

薄钢板通风管道制造装置项目中，包含弯头三通变径管天圆地方等管件及法兰加固框和吊托支架的制造用工但不包含过跨风管落地支架，落地支架履行设备支架项目。烟道过于狭窄，大排量烟机一般每分钟排风量会在13立方米左右，过于狭小的烟道会造成排风受阻，气流回转，风压加大产生的噪音，还有就是要检查一下看看排烟管是否深入烟道过多，在墙壁或天花板上砌上消音砖，或涂上消音漆以及安装隔音门等。

In the manufacturing equipment project of thin steel plate ventilation ducts, it includes the manufacturing labor for pipe fittings such as elbows, tees, and variable diameter pipes, as well as flange reinforcement frames and suspension brackets. However, it does not include the cross span air duct floor bracket, which fulfills the equipment support project. The flue is too narrow, and the exhaust air volume of a large displacement fan is generally around 13 cubic meters per minute. A narrow flue can cause obstruction of the exhaust air, rotation of the airflow, and noise generated by increased air pressure. Additionally, it is necessary to check whether the exhaust pipe penetrates too deeply into the flue, lay soundproof bricks on the wall or ceiling, apply soundproof paint, and install soundproof doors.
