乐从钢材批发市场热镀锌钢板风管地下管廊有花镀锌板0.75/1.0/1.2mm ...

城市地下管线是指城市范围内供水、排水、燃气、热力、电力、通信、广播电视、工业等管线及其附属设施，是保障城市运行的重要基础设施和“生命线”。地下管廊建设的难点之一就是骨架钢基板,由于其使用时间长,需要具备足够的耐腐蚀性,这就要求基板必须有足够厚的锌层作为保护。

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.

锌镀层经钝化处理、染色或涂覆护光剂后，能显著提高其防护性和装饰性。镀锌板风管广泛应用于宾馆、商场、纺织、化纤、石油化工、机械制造、仪表、电子、医药、烟草、食品、医疗、仓储、写字楼以及地铁、人防、地下室等工程的送风、排风、排烟管道。

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.

镀锌板风管的厚度及规格根据要求可变，通常在连接的时候，镀锌板风管两端总是外接于配件（如弯头、变径）。一般情况下，两端没有凹槽并带密封圈。强度高、阻力小、密封性能好、外形美观、安装简单、使用寿命长。内外壁光滑，风道阻力小，送排风时不产生次噪声，降低能耗，节约运行费用；可现场制作、可切割、可钻孔、可开洞、安装简单，省工省时，缩短工期；镀锌板风管安装完工后不需要维护，减少维护经费。

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.
