(1)现象：板材表面不平整，厚度不平均，有显著的压痕、裂纹、砂眼、结疤和锈蚀等情况;风管平面下沉，侧面向外突出，有显著的变形。

(1): the plate surface is not flat, the average thickness, significant indentation, crack, sand hole, scarring and corrosion etc.; the wind pipe sinking plane, side outwards, significant deformation.

(2)危害性：系统运行时，风管漏风，造成不应有的空调负荷损失，并且影响风管的使用寿命;风管表面颤抖，产生噪声。

(2) harmfulness: when the system is running, the air leakage of the air duct will cause the loss of air conditioning load, and affect the service life of the air pipe. The surface of the wind pipe is shaking and producing noise.

(3)原因分析：制作风管前，没有对所用材料进行质量检查;没有丈量钢板厚度。

(3) cause analysis: before making the duct, there is no quality check on the material used; there is no measurement of the thickness of the steel plate.

(4)防治措施：先检查材料出厂合格证书和材料质量证实，然后检查材料外观;丈量钢板厚度。风管翘角、扭曲及弯头角度不正确。

(4) prevention and control measures: first check the material, the factory certificate and the quality of materials confirmed, and then check the appearance of the material; measuring steel thickness. The air pipe is warped, twisted and the angle of the elbow is incorrect.

(1)现象：矩形风管两相对平面不平行、两端面不平行;折角不平直;对角线不相等;咬口不严。

(1) phenomenon: the rectangular air duct two is not parallel to the plane, and the ends are not parallel; the angle is uneven and straight; the diagonal is unequal; the bite is not strict.

(2)危害性：会使风管连接受力不平均，安装后的风管不平直，法兰盘垫片不严密，系统漏风，造成空调负荷损失，并且缩短使用寿命;影响风管、风口安装位置的正确。

(2) hazard: make wind force does not mean the connection, after the installation of the wind pipe is not straight, the flange gasket is not tight, resulting in the loss of system air leakage, air conditioning load, and shorten the service life; the influence of wind pipe, install the air position right.

(3)原因分析：板下料放样不正确;风管两两平行，相对面的板料长度和宽度不相等;风管的四角处咬口宽度不相等;咬口缝设置部位分歧错误，手工咬口缝用力大小不一样;未采取相应的加固措施。

(3) analysis: plate cutting lofting is not correct; the wind pipe 22 parallel, relative surface sheet length and width are not equal; the four corners of the duct is not equal to width of bite; bite sew setting position error, manual bite sew force is not the same; did not take corresponding strengthening measures.

(4)防治措施：展开下料时，应该对板料严格角方，对每片板料的长度、宽度以及检修对角线，使它们的偏差控制在答应范围内;下料后的板料，应该将风管相对面的两片板料重合起来，检修尺寸的正确性;板料咬口预留尺寸必需准确，以保证咬口宽度一致;

(4) prevention measures: when feeding on the sheet should be strictly angle, for each piece of sheet length, width and maintenance of diagonal, so that their deviation control in promised range; sheet material, should be relatively the two wind pipe plate material overlap, right repair size; sheet bite size must be reserved to ensure accurate and consistent width of bite;
