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. Supporting principle
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. Layout form of pipeline processing system network
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. Laying principle
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.
管道应尽可能成列布置，并尽可能沿墙或柱平行敷设。如果管径较大或保温应设在墙侧;一般情况下，两条管道平行敷设时，间距不应小于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. Different dust containing gases have different properties, so the purification of segmented treatment should be different.
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. Connection principle of ventilation duct treatment system
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. 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. The layout of air duct should minimize its length and unnecessary turning. The air conditioning box shall be located in the basement.
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.
