Advantages of double layer stainless steel chimney

重量轻：是碳钢烟囱的1/4~1/5，从而对建筑物荷重小。

Light weight: it is 1 / 4 ~ 1 / 5 of the carbon steel chimney, so the load on the building is small.

易安装：产品安装简便、快捷，在高层建筑物等狭小空间施尤为方便。

Easy to install: the product is easy and fast to install, especially in narrow space such as high-rise buildings.

外观美：外形平直、明亮、洁净和现代建筑配套相协调。

Beautiful appearance: straight, bright, clean and modern building matching.

性能好：气密性好、不腐蚀、耐热、保温、阻力小、产品使用安全可靠。

Good performance: good air tightness, non corrosion, heat resistance, heat preservation, small resistance, safe and reliable use of products.

好维护：不必定期做防腐处理。

Good maintenance: do not need to do regular anti-corrosion treatment.

寿命长：期望寿命不少于50年。

Long life: the expected life is not less than 50 years.

双层不锈钢烟囱特点是产品重量轻、耐腐蚀、保温、隔热性能好、使用寿命长、外型美观、大方;装卸简便、性能好，是砖、水泥、普通碳钢板烟囱的更新换代产品。

The double-layer stainless steel chimney is characterized by light weight, corrosion resistance, heat preservation, good heat insulation performance, long service life, beautiful appearance and generous appearance, easy loading and unloading, and good performance. It is the replacement product of brick, cement and common carbon steel chimney.

双层不锈钢烟囱整体结构采用分段式组合,可灵活组成任意走向，烟囱每段基本由内筒、外筒、环板、支撑、隔热材料等装配成单节部件，不锈钢烟囱每节之间的联接采用特殊材料密封,并由环形抱箍精密组合，拐角、转向处用曲管、三通等部件抱箍卡接处理,对温差引起的位移用伸缩节及补偿器进行完全补偿，在锅炉出口处或局部横向烟道上装有防爆门，烟囱的生产过程全部在自动化及专用设备上进行，能高质量地提供各种规格的烟囱部件。

The overall structure of the double-layer stainless steel chimney adopts sectional combination, which can flexibly form any direction. Each section of the chimney is basically composed of inner tube, outer tube, ring plate, support, heat insulation materials, etc. and is assembled into a single section. The connection between each section of the stainless steel chimney is sealed with special materials, and is precisely combined by ring hoop. The corner and turning place are clamped with curved pipe, tee and other components, The displacement caused by temperature difference shall be fully compensated by expansion joints and compensators, and explosion-proof doors shall be installed at the boiler outlet or local horizontal flue. The production process of chimney shall be carried out on automation and special equipment, which can provide various specifications of chimney components with high quality.
