Stainless steel spiral duct, as a kind of duct, does not need a large installation space, because it only needs a small installation space. Moreover, compared with the rectangular duct system, it is simpler, because the rectangular duct system also needs to add bolt system, so as to carry out its installation work. The ventilation pipe has the following characteristics:

1、外觀光滑，無鋅瘤、毛刺，呈銀白色；

1. Smooth appearance, no zinc tumor, burr, silver white;

2、安裝方便，連接點少；

2. It is easy to install and has few connecting points;

3、通風阻力小，通風噪聲小；

3. The ventilation resistance is small and the ventilation noise is small;

4、強度與剛性均好；

4. The strength and rigidity are good;

5、厚度均為可控，在5-107μm之內任意選擇；

5. The thickness is controllable and can be selected within 5-107 μ M;

6、無氫脆、無溫度危害，可保證材料力學性能不變；

6. No hydrogen embrittlement, no temperature hazard, can ensure the mechanical properties of the material unchanged;

7、可代替部分需熱鍍鋅的工藝；

7. It can replace part of the hot-dip galvanizing process;

8、耐腐蝕性好，中性鹽霧試驗達240小時；

8. Good corrosion resistance, neutral salt spray test up to 240 hours;

9、采用熱鍍鋅方法完成，適用于各種強酸、堿霧氣等強腐蝕環境中；

9. It is finished by hot galvanizing, suitable for all kinds of strong corrosive environment such as strong acid and alkali fog;

濟南通風管道加工時應注意的問題有哪些?

What problems should be paid attention to in Jinan ventilation pipe processing?

1、通風管道在運輸過程應有防止損傷風管的保護措施。

1. The ventilation pipe should be protected from damage during transportation.

2、榫接風管的連接在榫口處涂膠粘劑，是為增強接頭處的強度。

2. The connection of tenon air duct is coated with adhesive at the tenon to enhance the strength of the joint.

3、當風管采用地面預組裝后架空安裝時，限制預組裝的長度是為了遮免風管因自重產生的彎曲而破壞構件接口。

3. When the air duct is installed overhead after ground pre assembly, the length of pre assembly is limited to prevent the bending of the air duct due to its own weight from damaging the component interface.

4、玻璃纖維復合板風管端口為切割面時，在裝配法蘭連接件前應將管端切口面用膠帶或膠液進行封堵，濟南通風管道加工才能防止玻璃纖維外露和飛散。

4. When the end of the fiberglass composite board air duct is the cutting surface, the cutting surface of the pipe end should be sealed with tape or glue before assembling the flange connector, so as to prevent the exposure and dispersion of the fiberglass during the processing of Jinan ventilation pipe.

5、非法蘭連接的玻璃纖維復合板風管垂直安裝的支撐件制作與安裝的方法。

5. This paper introduces the method of making and installing the support for vertical installation of non flange connected fiberglass composite board air duct.
