很多场所都会选择安装通风管道，因为通风管道本身就有净化空气的优势，越来越多的人开始密切的接触通风管道。那么在管道设备的加工过程中可能会出现的管道问题有什么呢？还需要考虑什么呢？
Many places will choose to install ventilation ducts, because the ventilation ducts themselves have the advantage of purifying the air, and more and more people begin to closely contact the ventilation ducts. What are the possible pipeline problems during the processing of pipeline equipment? What else to consider?
不允许弯管和弯角
Bends and corners are not allowed
原因：板下料放样不准确，排气管平行成两条，板长和板宽不相等。
Cause: the blanking and setting out of the plate is not accurate, the exhaust pipe is parallel in two, and the plate length and width are not equal.
性能：长方形通风管有两个相对的平面，两端不平行，拐角不直，对角线不平，咬合不严。
Performance: the rectangular ventilation pipe has two opposite planes, the two ends are not parallel, the corners are not straight, the diagonals are uneven, and the bite is not tight.
效果：通风管道连接受力不均，安装后通风管道不平整，法兰盘密封不严，系统漏风，造成空调负荷损失，缩短使用寿命。
Effect: uneven stress of ventilation pipe connection, uneven ventilation pipe after installation, loose sealing of flange plate, air leakage of system, resulting in air conditioning load loss and shortening service life.
方法：展开、下料时，板材应有严格的边角，严格控制每张板材的长度、宽度和检验对角线，使偏差控制在允许范围内；下料后，应将与通气管相对的两张板对角重叠，以检查尺寸精度。
Methods: when unfolding and blanking, the plates shall have strict edges and corners, and the length, width and inspection diagonal of each plate shall be strictly controlled to control the deviation within the allowable range; After blanking, the two plates opposite to the vent pipe shall be overlapped diagonally to check the dimensional accuracy.
加工材料不合格
Unqualified processing materials
原因：原材料不合格，不能满足制造通风管的要求。
Cause: the raw materials are unqualified and cannot meet the requirements for manufacturing ventilation pipes.
性能：板面不平整，厚度不均，有明显的压痕、裂纹、砂孔、锈蚀等；通风管平面下沉，侧面凸出，变形明显。运行过程中，通风管道漏风，增加空调负荷，影响风机寿命和运行性能。
Performance: uneven plate surface, uneven thickness, obvious indentation, crack, sand hole, rust, etc; The plane of the ventilation pipe is sinking, the side is protruding, and the deformation is obvious. During operation, the ventilation duct leaks, which increases the air conditioning load and affects the fan life and operation performance.
方法：在使用通风管加工设备制造通风管之前，检查材料出厂合格证、材料质量合格证和外观厚度等，确保材料齐全。
Methods: before using the ventilation pipe processing equipment to manufacture the ventilation pipe, check the material factory certificate, material quality certificate and appearance thickness to ensure that the materials are complete.
通风管道的主要考虑因素有哪些？
What are the main considerations for ventilation ducts?
通风管道的考虑主要包括风口、风管、风门、风设备和一些配件。这次镀锌圆法兰主要强调的是通风管道管道和通风管道系统中的风门的操作注意事项：它是风管的识别。风管改造前，其中一项内容是明确的，那就是风管的标高。使用高度调整命令查看时，有时显示的结果会有所不同。这是因为管道和管道的标高是管道的标高。只要管道的高度很高，就将管道视为管道。
Ventilation duct mainly includes air outlet, air duct, air door, air equipment and some accessories. The galvanized round flange mainly emphasizes the precautions for the operation of the ventilation duct and the damper in the ventilation duct system: it is the identification of the air duct. Before the reconstruction of air duct, one of the contents is clear, that is, the elevation of air duct. When viewing with the height adjustment command, sometimes the results displayed will be different. This is because the pipe and the elevation of the pipe are the center elevation of the pipe. Pipes are considered pipes as long as they are high.
通风管

以其良好的性能和低廉的运行成本，广泛应用于造船、通风、空调、净化、桥梁除尘、机场、隧道等建筑行业。空调风管常用于冷热风的供给，需要保温材料。还可粘贴保温材料，使风道螺旋形美观，避免吊顶，降低工程成本。与传统风管相比，螺旋风管具有明显的技术、、、经济等优势，因此成为市场的宠儿。
With its good performance and low operating cost, it is widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries. Air conditioning ducts are often used for the supply of cold and hot air, and insulation materials are required. It can also be pasted with thermal insulation materials to make the air duct spiral beautiful, avoid ceiling and reduce project cost. Compared with traditional air duct, spiral air duct has obvious advantages in technology, energy saving, environmental protection and economy, so it has become the darling of the market.
与传统风管相比，螺旋风管的优势目前，大多数不锈钢风管企业起步较晚，资金实力有限，但为了在市场上获得一席之地，他们展开了战。
Compared with traditional air ducts, the advantages of spiral air ducts at present, most stainless steel air duct enterprises started late and have limited financial strength. However, in order to gain a place in the market, they launched a price war.
济南通风管道加工本身采用焊接工艺。经严格检验，可按客户要求组装。多种实用程序（常用卡箍和法兰两种）可以充分保证设备的稳定运行。使用寿命长，占地面积小。镀锌板螺旋风管制造工艺特点和优势不锈钢安装施工条件：不锈钢焊接风管排风系统和空调系统通风管的安装一般需要在建筑物屋顶完成，安装场地障碍已清理干净。
Jinan ventilation pipe processing itself adopts welding process. After strict inspection, it can be assembled according to customer requirements. A variety of utility programs (commonly used clamp and flange) can fully ensure the stable operation of the equipment. Long service life and small floor area. Manufacturing process characteristics and advantages of galvanized sheet spiral air duct installation and construction conditions of stainless steel: the installation of stainless steel welded air duct exhaust system and ventilation pipe of air conditioning system generally needs to be completed on the roof of the building, and the obstacles in the installation site have been cleared.
