通風管道大多是由風管加工設備制成，主要起到使空氣流通、降低有害氣體濃度的作用，但由于各種原因，加工出的風管會出現問題。下面就來為您講講通風管道生產加工的相關材料未達標問題內容。
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.
未達到標準的加工材料：表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼、結疤、銹蝕等現象；風管平面下沉，側面凸起，有明顯的變形。
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.
加工材料未達標的影響：風管在運轉時漏風，空調負荷增加，同時影響風壽命和性能。
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.
加工材料未達標的原因：材料不符合要求，無法滿足制造風管的要求。
Reasons for unqualified processing materials: the materials do not meet the requirements and cannot meet the requirements for manufacturing air ducts.
加工材料未達標的措施：在使用風管加工設備制作風管之前，應先檢查材料出廠合格證、材料質量證明書以及外型厚度等，確保材料是可用的。
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.
通風管道安裝時，進、出風日宜在預制構件預制孔前打開，如需在裝置終了的風道上現開風口，其接口應緊密。
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.
濟南通風管道加工人員認為當輸送含有冷凝水或高濕氣體時，其水平管道宜設置坡度，并在低點接排水管。在安裝過程中風道底部不要出現縱向接縫，對底部的接縫應中止處理。
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.
對于鋼板風道運輸易燃、易爆氣體，在風道連接法蘭處安裝跨接線，并與靜電接地網連接。
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.
