城市地下管線是指城市范圍內供水、排水、燃氣、熱力、電力、通信、廣播電視、工業(yè)等管線及其附屬設施，是保障城市運行的重要基礎設施和“生命線”。地下管廊建設的難點之一就是骨架鋼基板,由于其使用時間長,需要具備足夠的耐腐蝕性,這就要求基板必須有足夠厚的鋅層作為保護。

Urban underground pipeline refers to the water supply, drainage, gas, heat, electricity, communication, radio and television, industrial and other pipelines and their ancillary facilities within the city, which are important infrastructure and "lifeline" to ensure urban operation. One of the difficulties in the construction of underground pipe gallery is the skeleton steel substrate. Because of its long use time, it needs to have enough corrosion resistance, which requires that the substrate must have enough thick zinc layer as protection.

鋅鍍層經鈍化處理、染色或涂覆護光劑后，能顯著提高其防護性和裝飾性。鍍鋅板風管廣泛應用于賓館、商場、紡織、化纖、石油化工、機械制造、儀表、電子、醫(yī)藥、煙草、食品、醫(yī)療、倉儲、寫字樓以及地鐵、人防、地下室等工程的送風、排風、排煙管道。

After passivation treatment, dyeing or coating, the zinc coating can significantly improve its protective and decorative properties. Galvanized plate duct is widely used in hotels, shopping malls, textile, chemical fiber, petrochemical, machinery manufacturing, instrument, electronics, medicine, tobacco, food, medical, storage, office buildings and subway, civil air defense, basement and other projects of air supply, exhaust, smoke exhaust pipeline.

鍍鋅板風管的厚度及規(guī)格根據(jù)要求可變，通常在連接的時候，鍍鋅板風管兩端總是外接于配件（如彎頭、變徑）。一般情況下，兩端沒有凹槽并帶密封圈。強度高、阻力小、密封性能好、外形美觀、安裝簡單、使用壽命長。內外壁光滑，風道阻力小，送排風時不產生次噪聲，降低能耗，節(jié)約運行費用；可現(xiàn)場制作、可切割、可鉆孔、可開洞、安裝簡單，省工省時，縮短工期；鍍鋅板風管安裝完工后不需要維護，減少維護經費。

The thickness and specification of galvanized sheet duct are variable according to the requirements. Usually, both ends of galvanized sheet duct are always connected to the accessories (such as elbow, variable diameter). Generally, there are no grooves at both ends and they come with sealing rings. High strength, low resistance, good sealing performance, beautiful appearance, simple installation, long service life. The inner and outer walls are smooth, the air duct resistance is small, no secondary noise, reduce energy consumption and save operating costs; can be made, cut, drilled, drilled, simple installation, save time, shorten the construction period; galvanized plate duct does not need maintenance after installation, reduce maintenance expenses.
