焊接方式獨特，采用全新的低溫焊接形式，對產品鍍鋅層不產生破壞，焊點牢固，焊縫美觀，密封性好，焊后不需要對焊縫進行任何處理。
The welding method is unique and adopts a new low-temperature welding form, which does not damage the galvanized layer of the product. The welding points are firm, the weld seam is beautiful, and the sealing is good. After welding, there is no need to perform any treatment on the weld seam.
機械成型風管的制作使優的鍍鋅板不受傷害，鍍鋅層不被破壞，延長了使用壽命。
The production of mechanically formed air ducts ensures that the excellent galvanized sheet is not damaged, the galvanized layer is not damaged, and the service life is extended.
規格統一，尺寸標準，保證了管道內壁平整，光滑，因而便于潔凈，使物料輸送流暢。
Unified specifications and standardized sizes ensure that the inner wall of the pipeline is flat and smooth, making it easy to clean and smooth for material transportation.
自成型法蘭能使管道材質統一，a不再使用角鋼法蘭，減輕管道重量達20％以上，因此建筑物的承荷能力可大大減小，從而減少了建筑物的總體造價。
Self formed flanges can unify the material of pipelines, eliminate the use of angle steel flanges, and reduce the weight of pipelines by over 20%. Therefore, the load-bearing capacity of buildings can be greatly reduced, thereby reducing the overall cost of the building.
增強管道美觀，外觀漂亮，結構精巧，線條流暢，性能優越，安裝外露的風管，特別適用本產品。
Enhanced pipeline aesthetics, beautiful appearance, exquisite structure, smooth lines, superior performance, installation of exposed air ducts, especially suitable for this product.
典型的圓形風管件長一般3—6米，矩形管件長1—1.5米，減少了管件的連接點，使管件結合部的泄漏減小到低的程度。
A typical circular air pipe fitting is generally 3-6 meters long, while a rectangular pipe fitting is 1-1.5 meters long, reducing the connection points of the pipe fitting and minimizing the leakage at the joint of the pipe fitting.
機械化流水線制作的管件及接頭和零配件都有標準的密封圈，由于是標準化，工廠化生產，因而氣密性更好。
The pipe fittings, joints, and spare parts produced by the mechanized assembly line all have standard sealing rings. Due to the standardization and factory production, the air tightness is better.
機械成型的壓筋和加強筋，提高管壁的強度，可節約材料厚度，降低成本。西安螺旋風管廠家表示螺旋管的咬口潛縫厚度是管體的4倍，使管道的剛性非常大，具有好的承受壓力性能，特別是負壓尤其特出。
Mechanically formed compression and strengthening ribs can improve the strength of the pipe wall, save material thickness, and reduce costs. The manufacturer of spiral air ducts in Xi'an stated that the seam thickness of the spiral pipe is four times that of the pipe body, which makes the pipeline very rigid and has good pressure resistance, especially under negative pressure.
.科學的接縫，咬口方法，能保證管道氣體流暢，而不影響管道流通口徑。
Scientific jointing and biting methods can ensure smooth gas flow in the pipeline without affecting the diameter of the pipeline flow.
