按照現(xiàn)行的相關(guān)標(biāo)準(zhǔn)，對排煙通風(fēng)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(quán)威的檢測部門才有能力做到。

According to the current relevant national standards, there is a complete set of testing methods for wall thickness and fire resistance of smoke exhaust ventilation pipes, but these methods can only be achieved by authoritative testing departments.

市民要是想知道自己所買的房屋排煙通風(fēng)管道質(zhì)量是否過關(guān)，教你一招，辦法就是敲擊煙道壁，“合格排煙通風(fēng)管道，其煙道壁厚達(dá)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 the public wants to know whether the quality of the smoke exhaust and ventilation pipes of the houses they buy is good or not, the way is to knock on the wall of the flue, "Qualified smoke exhaust and ventilation pipes, the wall thickness of the flue is 1.5 cm, so when knocking on different parts of the wall of the flue, the sound is consistent, and more solid and crisp.

若是劣質(zhì)排煙通風(fēng)管道的話，由于壁厚不均勻，敲擊它的不同位置所發(fā)出的聲音是不一致的。”濟(jì)南通風(fēng)管道廠家告訴大家，排煙通風(fēng)管道安裝若是被業(yè)主重視的話，那么劣質(zhì)煙道從此就不再有市場了。

If the quality of smoke exhaust ventilation pipe, because the wall thickness is not uniform, the sound produced by tapping it at different locations is not the same. Jinan ventilation duct manufacturers told us that if the installation of smoke ventilation duct is valued by the owners, then the inferior flue will no longer have a market.

煙道機(jī)的性能好與壞直接決定排煙通風(fēng)管道的質(zhì)量,好的煙道機(jī)能夠生產(chǎn)出來好的排煙通風(fēng)管道，好的排煙通風(fēng)管道就能夠有好的，這是很好的理解的邏輯。

The performance of flue ventilator directly determines the quality of smoke exhaust ventilation duct, good flue ventilator can produce a good smoke exhaust ventilation duct, good smoke exhaust ventilation duct can have a good price, which is a very good understanding of the logic.

排煙通風(fēng)管道是以耐堿高強(qiáng)度玻璃纖維網(wǎng)格布為增強(qiáng)材料的水泥砂漿薄壁構(gòu)件，水泥應(yīng)采用強(qiáng)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(yīng)均勻。

The flue gas ventilation pipe is a thin-walled component of cement mortar reinforced by alkali-resistant and high-strength fiberglass mesh cloth. The cement should adopt quick-hardening sulphoaluminate cement with strength grade not less than 32.5 or low-alkalinity sulphate cement. Medium sand should be used. The wall thickness of flue gas duct should be uniform when the proportion of cement and sand is 1.

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

On the premise that reliable measures are taken to ensure no cracks in the flue gas passage during transportation and installation, the stiffness diaphragm can not be used.
