通风管道大多是由风管加工设备制成，主要起到使空气流通、降低有害气体浓度的作用，但由于各种原因，加工出的风管会出现问题。下面就来为您讲讲通风管道生产加工的相关材料未达标问题内容。
Most of the ventilation ducts are made of air duct processing equipment, which mainly plays a role in making the air circulate and reducing the concentration of harmful gases. However, due to various reasons, the processed air ducts will have problems. Now let's talk about the non-compliance of materials related to the production and processing of ventilation pipes.
未达到标准的加工材料：表面不平整，厚度不均匀，有明显的压痕、裂纹、砂眼、结疤、锈蚀等现象；风管平面下沉，侧面凸起，有明显的变形。
Processing materials that fail to meet the standard: the surface is uneven, the thickness is uneven, and there are obvious indentation, crack, sand hole, scar, rust and other phenomena; The plane of the air duct sinks, the side is convex, and there is obvious deformation.
加工材料未达标的影响：风管在运转时漏风，空调负荷增加，同时影响风寿命和性能。
Impact of unqualified processing materials: air leakage of air duct during operation, increase of air conditioning load, and impact on air service life and performance.
加工材料未达标的原因：材料不符合要求，无法满足制造风管的要求。
Reasons for unqualified processing materials: the materials do not meet the requirements and cannot meet the requirements for manufacturing air ducts.
加工材料未达标的措施：在使用风管加工设备制作风管之前，应先检查材料出厂合格证、材料质量证明书以及外型厚度等，确保材料是可用的。
Measures for unqualified processing materials: before using air duct processing equipment to manufacture air ducts, the factory certificate, material quality certificate and external thickness of materials shall be checked to ensure that the materials are available.
通风管道安装时，进、出风日宜在预制构件预制孔前打开，如需在装置终了的风道上现开风口，其接口应紧密。
During the installation of the ventilation duct, the air inlet and outlet should be opened before the prefabricated holes of the prefabricated components. If it is necessary to open an air outlet on the air duct at the end of the device, its interface should be tight.
济南通风管道加工人员认为当输送含有冷凝水或高湿气体时，其水平管道宜设置坡度，并在低点接排水管。在安装过程中风道底部不要出现纵向接缝，对底部的接缝应中止处理。
Jinan ventilation pipe processing personnel believe that when conveying condensate or high humidity gas, the horizontal pipe should be set with a slope and connected to the drainage pipe at the low point. Longitudinal joints shall not appear at the bottom of the air duct during installation, and the treatment of the joints at the bottom shall be suspended.
对于钢板风道运输易燃、易爆气体，在风道连接法兰处安装跨接线，并与静电接地网连接。
For flammable and explosive gas transported by steel plate air duct, jumper wire shall be installed at the connecting flange of air duct and connected with electrostatic grounding grid.
