专用的白铁加工剪刀、方锤、锉、钳、镊子、角尺，钢尺，白铁剪、切管器，电动的卷圆机、白铁压线机、白铁打扣机，如要焊风管架子，还要用到电焊机，角等。白铁加工的东西是比拟简单的，普通手工就能停止白铁加工。
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.

4. Consumption and sales of processing with supplied materials or customized products: all kinds of metal white iron products, aluminum plates, stainless steel and all kinds of square and round products, water closet, stainless steel workbench, shelf, water tank, vacuum bucket.
以白铁风管结构的革新为特征的共板法兰联接新工艺及其设备的应用，推进了金属风管加工技能的科学开展。
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.
传统的白铁风管管段之间的联接是将角钢或扁钢法兰与管端选用翻边、铆接或焊接方法固定后，再用多个螺栓把管段联接的工艺方法。
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.
共板法兰风管联接新工艺是选用滚压成形原理在风管两端滚压出法兰外形，再经过法兰角码和法兰夹将风管管段组合联接的一种新型工艺。
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.
白铁风管加工的首要工序是咬口加工和法兰制作，因角钢（扁钢）法兰制作费工、费料、加工周期长、质量保证环节多等缘由，不断成为限制通风空调体系施工功率和质量的首要要素。以风管本体自成法兰替代角钢（扁钢）法兰的共板法兰风管新工艺及其设备因工艺特征突出，一经问世，便受到本行业设计、施工、检验相关单位和人员的肯定和选用。
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.
