Nowadays, Jinan ventilation pipe processing is very common in our daily life. With the continuous development of economy, more and more people choose this kind of pipeline. But how much do you know about it? Do you know which layout points should be followed when dealing with this pipeline? If you don't know, follow up and learn!

1、支撐原則

1. Supporting principle

管道不應直接支撐在有閥門部件的設備上，應單獨設置支架或吊架。管道的焊接位置應在施工方便或應力小的地方。焊縫不應位于支架上，距離不應小于200毫米

The pipeline shall not be directly supported on the equipment with valve components, and the support or hanger shall be set separately. The welding position of the pipeline should be in the place where the construction is convenient or the stress is small. The weld shall not be located on the support and the distance shall not be less than 200 mm

2、管道加工系統網的布局形式

2. Layout form of pipeline processing system network

為了便于管網的管理和運行調整，管網系統不宜過大。當同一系統有多個支管時，這些支管應分級控制，同一系統的吸入點不應過多。需要注意每個支管的壓力平衡。有三種常見的管網布局模式：主管、單管和環管。

In order to facilitate the management and operation adjustment of the pipe network, the pipe network system should not be too large. When there are more than one branch pipe in the same system, these branch pipes should be controlled by stages, and the suction points of the same system should not be too many. Attention should be paid to the pressure balance of each branch pipe. There are three common pipe network layout modes: main pipe, single pipe and loop pipe.

3、鋪設原則

3. Laying principle

管道敷設應采用明裝暗裝，一般采用明裝。因為明裝便于維護，當無法使用外露安裝時，考慮采用隱蔽安裝方式。

The pipeline shall be installed in an open and concealed manner, generally in an open manner. Because the surface installation is easy to maintain, when the exposed installation cannot be used, the concealed installation method should be considered.

管道應盡可能成列布置，并盡可能沿墻或柱平行敷設。如果管徑較大或保溫應設在墻側;一般情況下，兩條管道平行敷設時，間距不應小于100 ~ 200毫米

Pipes shall be arranged in rows as far as possible and parallel to walls or columns as far as possible. If the pipe diameter is large or the insulation should be set at the wall side; in general, when two pipes are laid in parallel, the spacing should not be less than 100 ~ 200 mm

4、不同的含塵氣體性質不同，分段處理的凈化應不同。

4. Different dust containing gases have different properties, so the purification of segmented treatment should be different.

當污染源長時間集中在一個凈化系統中時，它們可以分為幾個系統。然而，污染物的混合會導致燃燒、爆炸危險以及不同溫度和濕度的氣體。混合后，管道中會出現冷凝、灰塵或不同性質的氣體，影響回收或凈化效率。

When pollution sources are concentrated in one purification system for a long time, they can be divided into several systems. However, the mixing of pollutants can lead to combustion, explosion hazard and gases with different temperature and humidity. After mixing, condensation, dust or gases with different properties will appear in the pipeline, which will affect the recovery or purification efficiency.

5、通風管道處理系統連接原則

5. Connection principle of ventilation duct treatment system

以焊接為主要連接方式的管道，應設置足夠數量的法蘭連接，以螺紋為主要連接方式的管道，應設置足夠數量的柔性接頭，以適合安裝、拆卸和檢修。

For pipelines with welding as the main connection mode, sufficient flange connections shall be set; for pipelines with thread as the main connection mode, enough flexible joints shall be set to suit for installation, disassembly and maintenance.

6、布局要保證整個系統的泄漏量小，要保證吸塵口有足夠的風量;減少阻力。

6. The layout should ensure that the leakage of the whole system is small, there should be enough air flow at the dust suction port, and the resistance should be reduced.

7、風管的布置應盡量減少其長度和不必要的轉彎。空調箱應位于地下室內。

7. The layout of air duct should minimize its length and unnecessary turning. The air conditioning box shall be located in the basement.

濟南通風管道廣泛應用于公共設施領域，是酒店的排煙設備，空調通風設備是典型的通風管道。通風設備和管道設備制造商有自己的進料方法和特殊的原料進料通道。每種材料都有質量檢驗證書，以確保其性能。

Jinan ventilation pipe is widely used in the field of public facilities. It is the smoke exhaust equipment of hotel, and the air conditioning ventilation equipment is a typical ventilation pipe. Manufacturers of ventilation and plumbing equipment have their own feeding methods and special raw material feeding channels. Each material has a quality inspection certificate to ensure its performance and safety.
