冷軋鋼板法蘭通風(fēng)管道內(nèi)、外表面和內(nèi)部傳熱材料粘合堅(jiān)固，是確保復(fù)合型材料的基礎(chǔ)標(biāo)準(zhǔn)之一。超過(guò)一定總面積的家具板材缺點(diǎn)，不但危害風(fēng)管使用期限，并且有時(shí)候會(huì)降低其隔熱保溫實(shí)際效果。因此缺點(diǎn)不可超過(guò)6‰，以做到材料在系統(tǒng)軟件中的常規(guī)應(yīng)用。
The inner and outer surfaces of cold-rolled steel flange ventilation ducts and the internal heat transfer materials are firmly bonded, which is one of the basic standards to ensure composite materials. The defects of furniture boards with a total area exceeding a certain amount not only endanger the service life of the air duct, but also sometimes reduce the actual effect of its thermal insulation. Therefore, the defects shall not exceed 6 ‰, so as to achieve the normal application of materials in system software.
傳統(tǒng)式的通風(fēng)空調(diào)工程風(fēng)管橫著聯(lián)接，均選用扁鋼做成成對(duì)法蘭，各自鉚在風(fēng)管兩邊并反邊，運(yùn)用二根風(fēng)管的這對(duì)法蘭，正中間再加上密封墊片并且用地腳螺栓把她們相互連接。因?yàn)槭懿牧稀C(jī)器和作業(yè)的限定，風(fēng)管不太可能為降低這類連接頭做得較長(zhǎng)。
The traditional ventilation and air conditioning project air ducts are connected horizontally. Flat steel is used to make a pair of flanges, which are riveted on both sides of the air duct and opposite sides. This pair of flanges of two air ducts are used, with a sealing gasket in the middle and anchor bolts used to connect them. Due to the limitation of materials, machines and operations, it is unlikely that the air duct will be long enough to lower such connectors.
生產(chǎn)流水線機(jī)械自動(dòng)化、自動(dòng)化技術(shù)水平高，進(jìn)一步提高了制做效率及其風(fēng)管的制做精密度。
The production line has a high level of mechanical automation and automation technology, which further improves the manufacturing efficiency and precision of air duct manufacturing.
風(fēng)管開(kāi)創(chuàng)法蘭，風(fēng)管凈重，鍍鋅鐵風(fēng)管加工廠家，與傳統(tǒng)式角鋼法蘭較為，節(jié)省了法蘭槽鋼及聯(lián)接地腳螺栓，降低材料耗損。管段長(zhǎng)度大于1250mm或低壓風(fēng)管單側(cè)平面積大于1.2mm，中高壓風(fēng)管大于1.0mm，應(yīng)采用加固方法。質(zhì)量控制關(guān)鍵風(fēng)管與法蘭鉚接前應(yīng)進(jìn)行技術(shù)質(zhì)量審查，管段應(yīng)留出10mm翻邊量。連接法蘭鉚釘時(shí)，有必要將鉚釘線垂直于板面，使鉚釘頭壓緊板材，使板縫緊密。
Compared with traditional angle steel flange, the air duct creates flange, net weight of air duct, and galvanized iron air duct processing factory, saving flange channel steel and connecting anchor bolts, and reducing material consumption. If the length of the pipe section is greater than 1250mm, or the flat area of one side of the low pressure air duct is greater than 1.2mm, and the medium and high pressure air duct is greater than 1.0mm, the reinforcement method shall be adopted. Before riveting the key air duct and flange for quality control, technical quality review shall be carried out, and 10mm flanging shall be reserved for the pipe section. When connecting flange rivets, it is necessary to make the centerline of the rivet perpendicular to the plate surface to make the rivet head press the plate tightly and make the plate seam tight.
