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。上海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。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。上海风管加工厂作业地点要有相应的辅助设施，如梯子、架子、安全防护、消防器材，并有施工员的技术、质量、安全交底。

Ventilation duct operation conditions: Generally, the installation of the supply fan system and air conditioning system should be carried out after the construction of the building enclosure structure is completed, obstacles have been cleared, and the ground is free of debris. The installation of air purification systems for Shanghai air duct processing should be carried out on the ground where the components are installed inside the building, with the walls plastered and no dust flying or with dust prevention measures in place. The installation of air ducts for general dust removal systems should be carried out after the installation of process equipment in the factory or when the equipment foundation has been determined, and the orientation of equipment connectors and covers is known. The position and size of the reserved holes on site should meet the requirements of the drawings, and each side should be 100mm larger than the actual cross-section. The operation site of the Shanghai air duct processing plant should have corresponding auxiliary facilities, such as ladders, shelves, safety protection, fire equipment, and have technical, quality, and safety instructions from construction workers.

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。

Ventilation duct material requirements: All installation materials should have factory certificates of conformity or quality appraisal documents and product lists. The finished air duct shall not have defects such as deformation, distortion, cracking, holes, flange detachment, welding, missing riveting, or missing bolt holes; The installed valve body, air outlet and other components should be checked for flexibility in the adjustment device, and for damage to the sound-absorbing plate and paint layer. The materials used for installation: bolts, nuts, washers, gaskets, sealing strips, self tapping screws, rivets, welding rods, various canvas, non-woven fabrics, injection nails, and expansion bolts should meet the product quality requirements. Iron sheet pipe manufacturers have very strict requirements for the production of plates, spiral duct manufacturer profiles, and other main finished materials used in their production. The weld seam should undergo visual inspection, and there should be no defects such as pores, sand holes, slag inclusions, cracks, etc. The deformation of the steel plate after welding should 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，上海通风管道又具有吸音降噪、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，并且具有抑菌和消声功能。

The air duct of the iron sheet air duct is connected to the air outlet using a flexible hose with an insulation layer. The installation of the iron sheet air duct should be flat and straight, and the installation of the main air duct of the common plate air duct should have an unevenness of ≤ 1.5mm/m and an unevenness of ≤ 1mm/m. The surface of the iron sheet air duct and accessories should be flat, with even arcs, and the longitudinal joints should be staggered. The bite seams should be tight and the width should be even. Iron sheet pipe manufacturers introduce that in addition to the advantages of good stiffness and strength, iron sheet air ducts in Shanghai also have the properties of sound absorption, noise reduction, insulation, and no need for secondary insulation. This overcomes the weakness of weak composite air ducts and easy damage to the outer wall in the past, and promotes the advantages of galvanized iron sheets. Air duct manufacturers have a longer service life, are beautiful and generous, and show more noble colors. The inner thermal insulation material is phenolic foam with good incombustibility in organic materials. The pipe does not need secondary thermal insulation after molding, and has antibacterial and noise elimination functions.
