                白鐵皮通風管道加工技術要求

                濟南鐵皮風管加工廠家在此講講白鐵皮通風管道加工工藝要求:

                The Jinan iron sheet air duct processing manufacturer is here to discuss the requirements for the processing process of white iron sheet air ducts:

                應采用咬口連接或鉚接,不得焊接。白鐵皮通風管道板材拼接的咬口縫應錯開,不得有十字型拼接縫。咬口縫緊密、寬度一致,折角平直,圓弧均勻且兩端面平行。

                It should be connected by biting or riveting, and welding is not allowed. The bite seams of the splicing of white iron sheet ventilation duct boards should be staggered and there should be no cross shaped seams. The bite seam is tight, the width is consistent, the folding angle is straight, the arc is even, and the two end faces are parallel.

                核實風管系統的標高,軸線、預留孔洞,預埋件等是否符合安裝條件。備足安裝用的各類輔助材料,準備好吊裝機具和安裝用的其它工具,對風管系統劃線定位等工作。

                Verify whether the elevation, axis, reserved holes, and embedded parts of the air duct system meet the installation conditions. Prepare various auxiliary materials for installation, prepare lifting equipment and other tools for installation, and mark and position the air duct system.

                角鋼規格可以略小于法蘭規格,當大邊尺寸為630-800mm時,可采用∠25*4的扁鋼做加固框;當大邊尺寸為800-1250mm時可采用∠25*25*4的扁鋼做加固框。

                The size of the angle steel can be slightly smaller than the flange size. When the large edge size is 630-800mm, a ∠ 25 * 4 flat steel can be used as the reinforcement frame; When the size of the large edge is 800-1250mm, a ∠ 25 * 25 * 4 flat steel can be used as a reinforcement frame.

                風管板材采用咬口連接時,咬口的形式有單咬口、聯合角咬口、轉角咬口、按扣式咬口和立咬口。其中單咬口、聯合角咬口、轉角咬口適用于微壓、低壓、中壓及高壓系統。

                When the air duct board is connected by bite, the forms of bite include single bite, combined corner bite, corner bite, snap fit bite, and vertical bite. Single bite, combined corner bite, and corner bite are suitable for micro pressure, low pressure, medium pressure, and high pressure systems.

                在較大規模的風管制作項目中,卷板可以提高工效。但是卷板必須經過校正,否則會因為鋼板本身的變形而影響風管加工的外觀質量。

                In large-scale air duct production projects, rolling plates can improve work efficiency. However, the rolling plate must be calibrated, otherwise it will affect the appearance quality of the air duct processing due to the deformation of the steel plate itself.

                白鐵皮通風管道的板材加工厚度應符合產品標準,產品標準中板材公稱厚度是允許有偏差,不同精度要求、寬度不同、屈服強度不同,允許偏差是不一樣的。

                The processing thickness of the sheet metal ventilation pipeline should comply with the product standard. The nominal thickness of the sheet metal in the product standard allows for deviation, and the allowable deviation varies depending on the accuracy requirements, width, and yield strength.

                立管支架不足。GB50243規定,垂直安裝時,支架間距不應大于4m。班組一般都是每層做一個支架,對于商業項目,層高往往超過4m,這就需要每層中間還需要加一個支架。

                Insufficient stand pipe support. GB50243 stipulates that when installed vertically, the spacing between supports should not exceed 4m. Teams usually make a bracket for each floor. For commercial projects, the height of the floor often exceeds 4m, which requires an additional bracket in the middle of each floor.
