At present, people pay more and more attention to the installation of ventilation and smoke exhaust pipes. It is normal for many people not to know much because they are not professional. It is only by casually looking for some small workshops on the street to make smoke exhaust and ventilation pipes that some black heart workshops can take advantage of to make low-quality smoke exhaust pipes.

市民以后在買房驗房時，不但要注意房屋表面上的質量問題，要關注看不見的質量問題。”山東通風排煙管道加工廠家提醒大家，按照現行的相關標準，對排煙通風管道的壁厚、耐火性能等有一套完整的檢測方法，但這些方法只有權威的檢測部門才有能力做到。

When buying and inspecting houses in the future, citizens should not only pay attention to the quality problems on the surface of the house, but also pay attention to the invisible quality problems. " Shandong ventilation and smoke exhaust pipe processing factory reminds you that according to the current relevant national standards, there is a complete set of testing methods for the wall thickness and fire resistance of smoke exhaust and smoke exhaust pipes, but only the authoritative testing department can do these methods.

市民要是想知道自己所買的房屋排煙通風管道質量是否過關，教你一招，辦法就是敲擊煙道壁，“合格通風排煙管道，其煙道壁厚達1.5厘米，因此在敲擊煙道壁的不同部位時，聲音一致，且比較渾實、清脆。

If citizens want to know whether the quality of the smoke exhaust and ventilation duct of the house they buy is qualified, they can teach you a trick by knocking on the flue wall. "Qualified ventilation and smoke exhaust duct has a flue wall thickness of 1.5cm. Therefore, when knocking on different parts of the flue wall, the sound is consistent, solid and crisp.

若是劣質通風排煙管道的話，由于壁厚不均勻，敲擊它的不同位置所發出的聲音是不一致的。”山東通風排煙管道加工廠家告訴大家，通風排煙管道安裝若是被業主重視的話，那么劣質煙道從此就不再有市場了。

If it is a poor ventilation and smoke exhaust pipe, the sound made by knocking on different positions is inconsistent due to the uneven wall thickness. " Shandong ventilation and smoke exhaust pipe processing manufacturer told you that if the ventilation and smoke exhaust pipe installation is valued by the owner, then the inferior flue will no longer have a market.

煙道機的性能好與壞直接決定排煙通風管道的質量,好的煙道機能夠生產出來好的排煙通風管道，好的排煙通風管道就能夠有好的，這是很好的理解的邏輯。

The good or bad performance of the flue fan directly determines the quality of the smoke exhaust and ventilation duct. A good flue fan can produce a good smoke exhaust and ventilation duct, and a good smoke exhaust and ventilation duct can have a good price, which is a well understood logic.

通風排煙管道是以耐堿高強度玻璃纖維網格布為增強材料的水泥砂漿薄壁構件，水泥應采用強度等級不低于32.5的快硬硫鋁酸鹽水泥或低堿度硫酸鹽水泥，采用中砂，水泥與砂的配比為1煙氣道壁厚應均勻。

The ventilation and smoke exhaust duct is a cement mortar thin-walled component reinforced by alkali resistant high-strength glass fiber mesh cloth. The cement shall be fast hardening sulphoaluminate cement or low alkalinity sulfate cement with strength grade not less than 32.5, medium sand shall be used, and the ratio of cement and sand shall be 1. The wall thickness of the smoke duct shall be uniform.

在有可靠措施確保煙氣道運輸和安裝過程中煙氣道不出現裂紋的前提下，可不采用加強剛度隔板。

On the premise that there are reliable measures to ensure that there are no cracks in the flue gas duct during the transportation and installation of the flue gas duct, the strengthened stiffness diaphragm may not be used.

1、可以選用復合資料現場制造巨細通、彎頭號配件也十分便利，因而施工速度快，且對施工人員的需求也相對下降。

1. Composite materials can be selected, and it is also very convenient to manufacture large and small fittings and elbow fittings on site. Therefore, the construction speed is fast, and the demand for construction personnel is also relatively reduced.

2、在有可靠措施確保煙氣道運輸和安裝過程中煙氣道不出現裂紋的前提下，可不采用加強剛度隔板。

4、通風管道對裝置精度的需求也相對較低，這又能夠進步風管的裝置速度。通風管道工程定義可以解釋為：送風、排風、除塵、氣力輸送以及防、排煙系統工程的總稱。

4. The demand of ventilation duct for device accuracy is also relatively low, which can improve the device speed of air duct. The definition of ventilation duct engineering can be interpreted as the general term of air supply, exhaust, dust removal, pneumatic conveying and smoke control and exhaust system engineering.

山東通風管道加工的性能好與壞直接決定排煙通風管道的質量,好的煙道機能夠生產出來好的排煙通風管道，在選擇質量好的通風管道的前提是對通風管道有一個基本的了解，希望以上的幾點建議對大家有所幫助。

The good or bad processing performance of Shandong ventilation duct directly determines the quality of smoke exhaust ventilation duct. A good flue fan can produce a good smoke exhaust ventilation duct. The premise of selecting a good quality ventilation duct is to have a basic understanding of the ventilation duct. I hope the above suggestions will be helpful to you.
