3. The screw hole of the hanger shall be processed, the hanger shall be straight, and the threaded end shall be complete and smooth.

4.對(duì)于長(zhǎng)度超過(guò)20m的水平懸掛風(fēng)管，在風(fēng)管施工時(shí)，應(yīng)少設(shè)置一個(gè)防擺支架。

4. For horizontal suspended air duct with a length of more than 20m, at least one anti swing support shall be set during air duct construction.

5.支架和吊架不應(yīng)設(shè)置在風(fēng)口、閥門、檢查門和自動(dòng)控制機(jī)構(gòu)處，距風(fēng)口或插頭連接處的距離不應(yīng)小于200mm。

5. The support and hanger shall not be set at the air outlet, valve, inspection door and automatic control mechanism, and the distance from the air outlet or plug connection shall not be less than 200mm.

6.水平懸掛干管和干風(fēng)管長(zhǎng)度超過(guò)20m時(shí)，應(yīng)設(shè)置防止擺動(dòng)的固定點(diǎn)，每個(gè)系統(tǒng)不少于1個(gè)。

6. When the length of horizontal suspension main pipe and main air pipe exceeds 20m, fixed points to prevent swing shall be set, and each system shall have at least one fixed point.

7.汽水管道應(yīng)根據(jù)標(biāo)準(zhǔn)圖紙、規(guī)范和規(guī)程選擇具有適當(dāng)強(qiáng)度和剛度的管道。濟(jì)南通風(fēng)管道直徑或長(zhǎng)度超過(guò)2500超寬，超重的專用風(fēng)管支吊架應(yīng)在規(guī)定設(shè)計(jì)中。

7. Steam and water pipes shall be selected with appropriate strength and stiffness according to national standard drawings, specifications and procedures. The special air duct supports and hangers with the diameter or length of Jinan air duct exceeding 2500 and super wide and overweight shall be included in the specified design.

螺旋風(fēng)管的安裝顯著減少了管道之間的連接點(diǎn)，將管件連接處的泄漏降低到很低的程度。典型的螺旋風(fēng)管長(zhǎng)度為3~6m，而典型的矩形風(fēng)管長(zhǎng)度僅為1 ~ 1.5m并且只需要一個(gè)管接頭來(lái)連接兩個(gè)螺旋風(fēng)管，而傳統(tǒng)的矩形風(fēng)管連接往往需要完全獨(dú)立的雙法蘭系統(tǒng)。

The installation of spiral air duct significantly reduces the connection points between pipes and reduces the leakage at the connection of pipe fittings to a very low level. The typical spiral air duct is 3~6m long, while the typical rectangular air duct is only 1~1.5m long and only one pipe joint is needed to connect two spiral air ducts, while the traditional rectangular air duct connection often requires a completely independent double flange system.

1.標(biāo)準(zhǔn)化產(chǎn)品。

1. Standardized products.

螺旋管道配件(管件和接頭)的生產(chǎn)已經(jīng)高度自動(dòng)化和系統(tǒng)化，并有工業(yè)化的質(zhì)量控制。

The production of spiral pipe fittings (pipe fittings and joints) has been highly automated and systematic, and has industrialized quality control.

2.安裝成本低。

2. Low installation cost.

圓形風(fēng)管系統(tǒng)的安裝時(shí)間僅為同類矩形風(fēng)管的1/3。

The installation time of round air duct system is only 1/3 of that of similar rectangular air duct.

3.通常只需要很小的安裝空間

3. Usually only a small installation space is required
