Ventilation ducts are indispensable in building construction. When making and installing pipelines, certain standards shall be followed to ensure the normal application of the completed pipelines and reduce the probability of common faults. What standards should be followed in production, manufacturing and installation?

1、風(fēng)管的生產(chǎn)制造和安裝應(yīng)依照設(shè)計(jì)圖、合同書(shū)及有關(guān)標(biāo)準(zhǔn)規(guī)范的要求開(kāi)展。一切變動(dòng)須附帶設(shè)計(jì)方案或合同變更通告或技術(shù)性準(zhǔn)許簽證辦理。

1. The production, manufacture and installation of air duct shall be carried out in accordance with the requirements of design drawings, contracts and relevant standards and specifications. All changes must be accompanied by design scheme or contract change notice or technical permit visa.

2、風(fēng)管系統(tǒng)軟件工程施工前，施工企業(yè)應(yīng)與施工單位、建設(shè)單位、總承包單位、設(shè)計(jì)方案企業(yè)等開(kāi)展融洽。對(duì)風(fēng)管等管路的部位邁向，查驗(yàn)預(yù)埋孔的安裝狀況等。工程施工應(yīng)與土建施工和別的技術(shù)技術(shù)工種相融洽。

2. Before the construction of air duct system software engineering, the construction enterprise shall be in harmony with the construction unit, construction unit, general contractor, design scheme enterprise, etc. Check the installation status of embedded holes for the parts of air ducts and other pipelines. The project construction shall be in harmony with civil construction and other professional technical types of work.

3、風(fēng)管制做與安裝常用板才、鋁型材及其其他關(guān)鍵制成品原材料，應(yīng)合乎設(shè)計(jì)方案及相關(guān)產(chǎn)品我國(guó)執(zhí)行標(biāo)準(zhǔn)的要求，并應(yīng)該有原廠檢測(cè)合格證實(shí)。原材料入場(chǎng)應(yīng)按我國(guó)現(xiàn)行標(biāo)準(zhǔn)相關(guān)規(guī)范開(kāi)展工程驗(yàn)收。

3. The raw materials of common plates, aluminum profiles and other key finished products used in the manufacture and installation of air ducts shall meet the requirements of the design scheme and relevant products' Executive Standards in China, and shall be verified by the inspection of the original factory. The project acceptance of raw materials shall be carried out in accordance with China's current standards and relevant specifications.

4、制成品通風(fēng)管道須有相對(duì)應(yīng)的企業(yè)資質(zhì)證書(shū)，包含關(guān)鍵原材料的材料資格證書(shū)、風(fēng)管的抗壓強(qiáng)度和密閉性測(cè)試報(bào)告(非金屬材料風(fēng)管還須給予消防和環(huán)境衛(wèi)生實(shí)驗(yàn)的合格匯報(bào))。

4. The finished ventilation duct must have the corresponding enterprise qualification certificate, including the material qualification certificate of key raw materials, the compressive strength and tightness test report of air duct (the non-metallic air duct must also be provided with the qualified report of fire control and environmental sanitation test).

5、風(fēng)管生產(chǎn)制造應(yīng)首先選擇環(huán)保節(jié)能、機(jī)械自動(dòng)化的生產(chǎn)加工技術(shù)性。

5. The production and processing technology of environmental protection, energy conservation and mechanical automation shall be selected for the production and manufacturing of air duct.

6、風(fēng)管生產(chǎn)制造安裝常用的檢測(cè)儀器和測(cè)試儀器應(yīng)處在合格情況并在合理檢測(cè)期限內(nèi)。

6. The testing instruments and instruments commonly used in the production, manufacturing and installation of air ducts shall be in qualified condition and within a reasonable testing period.

7、裝修隱蔽工程的風(fēng)管在隱敝前需經(jīng)工程監(jiān)理工作人員工程驗(yàn)收及認(rèn)同簽證辦理。

7. The air duct of concealed decoration works shall be subject to the project acceptance and approval visa of the project supervision staff before being concealed.

當(dāng)生產(chǎn)制造和安裝通風(fēng)管道時(shí)，他們都是有他們應(yīng)當(dāng)遵照的規(guī)定。搞好這種能夠使全部管路更為經(jīng)久耐用。

When manufacturing and installing ventilation ducts, they all have regulations they should follow. Doing this well can make all pipelines more durable.
