不锈钢风管通风管道常见故障检修透风严重，能源消耗。关键危害：整个系统风量损害过大，没法做到风量要求，并导致能源严重消耗。很有可能的缘故：咬口缝和法兰插条接缝处及孔眼缝隙处未用密封膏封严;管片开料咬口留量超过规范要求等。山东通风管道常见故障检修砖构造风道与金属风管连接处未设埋件或密封缝隙过大或连接处不严密。

Common malfunctions of stainless steel air ducts and ventilation ducts require severe ventilation and energy consumption. Key hazard: The air volume of the entire system is damaged too much, unable to meet the air volume requirements, and leading to serious energy consumption. It is highly likely that the sealing paste was not used to seal the bite joint, flange insertion joint, and hole gap; The biting allowance of the pipe segment exceeds the standard requirements. Common troubleshooting of ventilation ducts in Shandong: The connection between the brick structure air duct and the metal air duct is not equipped with embedded parts, or the sealing gap is too large or the connection is not tight.

　　应对措施：高压风管山东通风管道可选用按钮式咬口;髙压风管或清洁系统风管四角处运用拐角咬口缝或协同角咬口。不锈钢风管咬口缝、无法兰插条接缝处及孔眼缝隙处，都须用密封膏封严，不可透风。施工中按要求在砖、构造风道与金属风道连接处设定埋件，或要求土建企业配合开展堵封， 山东通风管道连接严密。

Response measures: High pressure air duct Shandong ventilation duct can choose button type bite; Use corner bite seams or synergistic corner bite seams at the corners of high-pressure air ducts or cleaning system air ducts. Stainless steel air ducts must be sealed tightly with sealing paste at the biting seam, non flange insertion strip seam, and hole gap, and must not be ventilated. During construction, embedded parts should be installed at the connection between bricks, structural air ducts, and metal air ducts as required, or civil engineering companies should cooperate to carry out sealing. The ventilation pipes in Shandong should be tightly connected.

　　金属极气体保护焊

Metal electrode gas shielded welding

　　它属于气体保护焊，也是一种电弧焊，是在维护气体下，焊丝被电弧溶化。金属极气体保护焊可用以钢、非碳素钢、低合金钢及其高合金等这种材料，应用很普遍。但有一点，通风管道它的维护气体务必为活性气体，例如二氧化碳或是混和气体等。的缺陷是假如在户外开展焊接，那麼工件不能受潮，不然会危害维护气体的维护效果。

It belongs to gas shielded welding and is also a type of arc welding, where the welding wire is melted by the arc under maintenance gas. Metal electrode gas shielded welding can be used for materials such as steel, non carbon steel, low alloy steel, and their high alloys, and is widely used. But one thing is that the maintenance gas for ventilation ducts must be active gases, such as carbon dioxide or mixed gases. The flaw is that if welding is carried out outdoors, the workpiece cannot be damp, otherwise it will endanger the maintenance effect of the gas.

　　钨极惰性气体保护焊

Tungsten inert gas shielded welding

　　电弧是在钨电焊丝和工件中间造成，不锈钢风管通风管道常见故障检修焊接要求维护气体为纯氩气，且焊条不是带电的，所以既能够手动送入，也可以设备送入，有时也可以不送入。

The arc is caused between the tungsten welding wire and the workpiece. Common faults in stainless steel air ducts and ventilation ducts require maintenance gas to be pure argon, and the welding rod is not charged. Therefore, it can be manually fed, equipment fed, or sometimes not fed.

　　导热系数小

Low thermal conductivity

　　保温材料导热系数均在，风管槽型法兰、卡条选用塑钢型材，铝合金、塑钢复合的型材，其风道无热桥，无结露。

The thermal conductivity of insulation materials is all within the range of. The groove type flange and clamp of the air duct are made of plastic steel profiles, and the aluminum alloy and plastic steel composite profiles are used. The air duct has no thermal bridge and no condensation.
