Special white iron processing scissors, square hammers, files, pliers, tweezers, angle rulers, steel rulers, white iron shears, pipe cutters, electric rolling machines, white iron wire presses, white iron bucklers, and electric welding machines, angles, etc. are also used to weld air duct racks. The white iron processing is relatively simple, and ordinary manual processing can stop the white iron processing.

以白鐵風(fēng)管結(jié)構(gòu)的革新為特征的共板法蘭聯(lián)接新工藝及其設(shè)備的應(yīng)用，推進(jìn)了金屬風(fēng)管加工技能的科學(xué)開展。

The application of new technology and equipment of common plate flange connection characterized by the innovation of white iron air duct structure has promoted the scientific development of metal air duct processing skills.

傳統(tǒng)的白鐵風(fēng)管管段之間的聯(lián)接是將角鋼或扁鋼法蘭與管端選用翻邊、鉚接或焊接方法固定后，再用多個(gè)螺栓把管段聯(lián)接的工藝方法。

The traditional connection between the white iron air duct sections is the process of connecting the pipe sections with multiple bolts after the angle steel or flat steel flange and the pipe end are fixed by flanging, riveting or welding.

共板法蘭風(fēng)管聯(lián)接新工藝是選用滾壓成形原理在風(fēng)管兩端滾壓出法蘭外形，再經(jīng)過法蘭角碼和法蘭夾將風(fēng)管管段組合聯(lián)接的一種新型工藝。

The new process of common plate flange air duct connection is a new process that uses the rolling forming principle to roll out the flange shape at both ends of the air duct, and then combines the air duct sections through flange corner pieces and flange clamps.

白鐵風(fēng)管加工的首要工序是咬口加工和法蘭制作，因角鋼（扁鋼）法蘭制作費(fèi)工、費(fèi)料、加工周期長、質(zhì)量保證環(huán)節(jié)多等緣由，不斷成為限制通風(fēng)空調(diào)體系施工功率和質(zhì)量的首要要素。以風(fēng)管本體自成法蘭替代角鋼（扁鋼）法蘭的共板法蘭風(fēng)管新工藝及其設(shè)備因工藝特征突出，一經(jīng)問世，便受到本行業(yè)設(shè)計(jì)、施工、檢驗(yàn)相關(guān)單位和人員的肯定和選用。

The primary process of white iron air duct processing is seaming processing and flange manufacturing. Because angle steel (flat steel) flange manufacturing is labor-intensive, material consuming, long processing cycle, and many quality assurance links, it has constantly become the primary factor limiting the construction power and quality of the ventilation and air conditioning system. The new process and equipment of common plate flange air duct with self formed flange of air duct body instead of angle steel (flat steel) flange are recognized and selected by relevant units and personnel in design, construction and inspection of the industry once they are introduced due to their outstanding process characteristics.
