铁皮风管在外观的加工制作上有什么要求?

发布时间:2019/08/01

  铁风道是一种非常常见的通风排气管基础设施,利用铁风道有效地使空气循环,降低有害气体的浓度。因此,铁管、板材、型材等主要产品的材质都是非常严格的,下面为您详细介绍铁管的生产要求:
  Railway duct is a very common ventilation and exhaust pipe infrastructure, which can effectively circulate air and reduce the concentration of harmful gases. Therefore, the material of main products such as iron pipes, sheets and profiles is very strict. The following is a detailed description of the production requirements of iron pipes by  Co., Ltd.
  1. 焊缝外观检查,无气孔、沙眼、夹渣、裂纹等缺陷,纠正钢板焊接后的变形;
  1. Weld appearance inspection, no air hole, trachoma, slag inclusion, cracks and other defects, correct the deformation of steel plate after welding;
  2、铁板风道保温层采用聚苯乙烯泡沫板生产,泡沫板密度:40纳米结构/m3,厚度35纳米结构(表面温度不得低于5℃),保温层边缘接缝采用梯形或榫槽结构,用树脂糊制而成。
  2. The insulation layer of iron plate air duct is made of polystyrene foam board. The density of the foam board is 40 nanometer structure /m3, the thickness is 35 nanometer structure (the surface temperature should not be lower than 5 degrees Celsius). The edge of the insulation layer adopts trapezoidal or tenon groove structure, and is made of resin paste.
  3.将铁板风管的风管、风口与带保温层的软管连接;
  3. Connect the air duct and tuyere of the iron plate air duct with the hose with insulation layer;
  4. 铁管的管道应平整、笔直。主风管小于或等于1.5 mm,但小于或等于1 mm;
  4. Pipes of iron pipes should be flat and straight. The main duct is less than or equal to 1.5 mm, but less than or equal to 1 mm.

  5. 铁板风管及附件表面平整,电弧均匀,纵向接缝应错开,咬合接缝应紧密,宽度应均匀;
  5. The surface of the iron plate air duct and accessories is flat, the arc is uniform, the longitudinal joint should be staggered, the occlusion joint should be tight and the width should be uniform.
  6. 制造铁管及配件,外径或外径允许偏差小于或等于300mm为- 1mm;-2mm大于300mm。风管系统中所有直角弯头均安装在消声器弯头内,消声器弯头内安装镀锌铁板导向器;
  6. Making iron pipes and fittings, the allowable deviation of outer diameter or outer diameter less than or equal to 300 mm is - 1 mm; - 2 mm is more than 300 mm. All right-angle elbows in the air duct system are installed in the muffler elbow, and galvanized iron plate guide is installed in the muffler elbow.
  7. 铁板风管的风管采用机械咬口,整齐严谨,接口内表面采用玻璃胶。
  7. The air duct of the iron plate air duct adopts mechanical bite, neat and rigorous, and the inner surface of the interface adopts glass glue.
