通风管道作业条件：一般送风机系统和空调系统的安装，要在建筑物围护结构施工完，障碍物已清理，地面无杂物的条件下进行。风管加工对空气洁净系统的安装，应在建筑物内部安装部件的地面已做好，墙面已抹灰完毕，室内无灰尘飞扬或有防尘措施的条件下进行。

Working conditions of ventilation duct: generally, the installation of forced draft fan system and air conditioning system shall be carried out after the construction of building envelope, the obstacles have been cleared and the ground is free of sundries. The installation of air cleaning system for air duct processing shall be carried out under the condition that the ground of the components installed inside the building has been completed, the wall has been plastered, and there is no dust flying or dust-proof measures in the room.

一般除尘系统风管安装宜在厂房的工艺设备安装完或设备基础已确定，设备连接器、罩体方位已知的情况下进行。检查现场预留孔洞位置、尺寸应符合图纸要求，每边比实际截面大100mm。

The air duct of general dust removal system should be installed after the process equipment of the plant is installed or the equipment foundation has been determined, and the orientation of equipment connector and cover body is known. Check that the position and size of the reserved holes on site shall meet the requirements of the drawing, and each side shall be 100mm larger than the actual section.

通风管道材质要求：各种安装材料应具有出厂合格证明书或质量鉴定文件及产品清单。风管成品不允许有变形、扭曲、开裂、孔洞、法兰脱落、开焊、漏铆、漏打螺栓孔等缺陷;安装的阀体、风口等部件应检查调节装置是否灵活，消声片、油漆层有无损伤。安装使用的材料：螺栓、螺母、垫圈、垫料、密封条、自攻螺钉，拉铆钉，焊条、各种帆布、无纺布、射钉、膨胀螺栓应符合产品质量要求。铁皮管道厂家在制作时,其所用板材、螺旋风管厂家型材以及其他主要成品材料制作要求十分严格。焊缝应作外观检查,不应有气孔、砂眼、夹渣、裂纹等缺陷,焊接后钢板的变形应矫正。

Material requirements for ventilation duct: various installation materials shall have factory certificate or quality appraisal document and product list. The finished air duct shall be free of deformation, distortion, cracking, holes, flange falling off, open welding, missing riveting, missing bolt holes and other defects; For the installed valve body, air outlet and other components, check whether the regulating device is flexible and whether the silencing sheet and paint layer are damaged. Materials used for installation: bolts, nuts, washers, gaskets, sealing strips, self tapping screws, pull rivets, welding rods, various canvas, non-woven fabrics, shooting nails and expansion bolts shall meet the product quality requirements. During the production of sheet iron pipe manufacturers, the production requirements of plates, profiles of spiral air duct manufacturers and other main finished materials are very strict. The weld shall be visually inspected without defects such as pores, sand holes, slag inclusions and cracks. The deformation of the steel plate after welding shall be corrected.

铁皮风管的风道与风口接合用带保温层的软管连接。铁皮风管的风道安装应平、直, 共板风管主风道安装不直度≤1.5㎜/m,不平度≤1㎜/m。铁皮风管和配件表面平整、圆弧均匀、纵向接缝应错开,咬口缝应紧密,宽度均匀。铁皮管道厂家介绍铁皮风管除具有刚度好、强度大的优点外，又具有吸音降噪、保温隔热不需要二次保温的性能，克服了以前复合风管强度弱，外壁易破损的弱点，发扬了镀锌铁皮的优势，风管厂家使用寿命更长，且美观大方，更显尊贵本色。内层保温材料为有机材料中不燃性能＊好的酚醛泡沫，管道在成型后不需要二次保温，并且具有和消声功能。

The air duct of the iron sheet air duct is connected with the air outlet with a hose with an insulating layer. The air duct of iron sheet air duct shall be installed flat and straight. The non straightness of the main air duct of common plate air duct shall be ≤ 1.5mm/m and the non flatness shall be ≤ 1mm / m. The surface of iron sheet air duct and accessories shall be flat, the arc shall be uniform, the longitudinal joints shall be staggered, the undercut joints shall be tight and the width shall be uniform. In addition to the advantages of good stiffness and high strength, iron duct has the performance of sound absorption, noise reduction, thermal insulation and no need for secondary insulation. It overcomes the weakness of weak strength of composite duct and easy damage of outer wall in the past, and carries forward the advantages of galvanized iron sheet. The service life of air duct manufacturers is longer, beautiful and generous, showing more noble nature. The inner insulation materials are nonflammable properties of organic materials * good phenolic foam. The pipes do not need two heat preservation after molding, and have antibacterial and silencing functions.
