Air is an important part of people's life. Without air, people will feel suffocated and unable to live. Oxygen in the air is also the basic element to maintain people's life. Therefore, it is necessary to keep indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation pipe processing in people's life. But what are the quality problems involved in the process? Next, Shandong Shenhe pipeline to introduce it.

山東通風管道是通風和空氣調節系統的重要組成部分，大部分都是由管道加工設備（如通風管道生產線）制成。但是由于各種各樣的原因，可能導致管道加工設備加工而成的通風管道出現問題。

Shandong ventilation pipeline is an important part of ventilation and air conditioning system, most of which are made by pipe processing equipment (such as ventilation pipe production line). However, due to a variety of reasons, it may lead to problems in the ventilation pipes processed by pipeline processing equipment.

1、加工材料未達標

1. Processing materials not up to standard

①表現：板材表面不平整，厚度不均勻，有明顯的壓痕、裂紋、砂眼和銹蝕等情況；通風管道平面下沉，側面向外凸起，有明顯的變形。

① Performance: the surface of the board is not smooth, the thickness is not uniform, there are obvious indentation, cracks, sand holes and rust; the plane of the ventilation pipe is sinking, the side is convex outward, and there is obvious deformation.

②影響：運轉時通風管道漏風，空調負荷增加，同時風壽命和性能被影響。

② Impact: during operation, the air duct leaks, the air conditioning load increases, and the air life and performance are affected.

③原因：材料不合格，不能滿足制作通風管道的需求。

③ Cause: the material is not qualified, can not meet the needs of making ventilation duct.

④措施：在使用通風管道加工設備制作通風管道前，要先檢查材料出廠合格證書和材料質量證明還有外觀厚度等，保證材料是可用的。

④ Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, it is necessary to check the material factory certificate, material quality certificate and appearance thickness to ensure that the material is available.

通風管道在很多工廠、學校等公共場所使用，主要是為了通風換氣，而在工廠中使用的通風管道不但要通風，而且還要保證車間的溫度恒定，一般車間溫度保持在25攝氏度，這是加工的需要，任何物質都有熱脹冷縮的作用，除水以外，所以在熱處理車間更是對溫度有嚴格的要求。

Ventilation pipes are used in many factories, schools and other public places, mainly for ventilation. The ventilation pipes used in factories not only need ventilation, but also ensure that the temperature of the workshop is constant. Generally, the temperature of the workshop is kept at 25 ℃, which is the need of processing. Any substance has the function of heat expansion and cold contraction. In addition to water, it is more important for the temperature in the heat treatment workshop There are strict requirements.

在熱處理車間安裝通風管道需要按照，車間安裝工藝圖紙進行安裝，然后根據實際需要進行調整，如果還不能保持室內溫度穩定，需要對車間溫度安裝調整器，一般的車間會以空調代替，所以我們也要為空調加裝通風設備，這些安裝的通風系統都是必不可少的。

In the heat treatment workshop, the ventilation pipes need to be installed according to the workshop installation process drawings, and then adjusted according to the actual needs. If the indoor temperature can not be kept stable, it is necessary to install the temperature regulator in the workshop. The general workshop will replace it with air conditioning. Therefore, we also need to install ventilation equipment for the air conditioner. The ventilation system installed is essential.

在安裝熱處理車間的通風管道，另一個需要考慮的因素就是耐腐蝕，由于大多數的熱處理車間都是在較高溫度下工作的，有時需要用水進行冷卻，這就會造成大量的水蒸氣蒸發，我們需要對我們管道的材料選取上下工夫了，這些氣體中都含有腐蝕性物質，所以管道一定要耐腐蝕。

Another factor that needs to be considered in the installation of ventilation pipes in heat treatment workshops is corrosion resistance. Since most heat treatment workshops work at higher temperatures, sometimes water is needed for cooling, which will cause a large amount of water vapor evaporation. We need to make efforts to select the materials of our pipes. These gases contain corrosive substances, so the pipelines It must be corrosion resistant.
