現在由環保通風管道加工廠家山東朗弘通風小編帶大家一起來了解一下通風管道制做安裝的驗收標準

Now, let's learn about the acceptance standards for the production and installation of ventilation ducts from Shandong Langhong Ventilation, an environmentally friendly ventilation duct processing manufacturer

1、通風管道安裝務必確保表面光潔、沒有受損的、無顯著缺點。

1. The installation of ventilation ducts must ensure a smooth surface, no damage, and no significant defects.

2.管路出風口表面應整平、色調勻稱。安裝部位應恰當。出風口的可調式一部分應能一切正常運作。

2. The surface of the pipeline air outlet should be flat and the color tone should be symmetrical. The installation location should be appropriate. The adjustable part of the air outlet should be able to operate normally.

3.通風管道制做安裝生產廠家告訴你，風管的聯接及其風管與機器設備或調整設備的聯接應有效。

3. The manufacturer of the ventilation duct production and installation tells you that the connection of the air duct and its connection with the machine equipment or adjustment equipment should be effective.

4.各種各樣通風管道調整設備的生產制造和安裝應堅固、靈便、便于實際操作。

4. The production, manufacturing, and installation of various ventilation duct adjustment equipment should be sturdy, flexible, and easy to operate.

5、管路構件和管道支架、支架的種類、部位和間隔應合乎本標準的規定。

5. The types, locations, and spacing of pipeline components, pipeline supports, and brackets shall comply with the provisions of this standard.

濟南市通風管道

Ventilation ducts in Jinan City

制做前的準備工作：

Preparation work before production:

1、制做風管前，要查驗選用的原材料是不是合乎品質規定，是不是有產品合格證明書或品質評定文檔。若濟南市通風管道無所述證明材料則應開展外型查驗，并應合乎以下規定：

1. Before making air ducts, it is necessary to check whether the selected raw materials comply with quality regulations and whether there is a product qualification certificate or quality assessment document. If there is no proof material for the ventilation ducts in Jinan City, an external inspection should be carried out and they should comply with the following regulations:

(1)板才表面應整平，薄厚應勻稱，無凹凸及顯著的擠傷狀況，并不可有裂痕、沙孔及、刺邊和生銹狀況;

(1) The surface of the board should be leveled, the thickness should be uniform, there should be no unevenness or significant crushing damage, and there should be no cracks, sand holes, sharp edges, or rust;

(2)槽鋼應當等型、勻稱，不需有裂痕、汽泡、窩穴以及它危害品質的缺點;

(2) Channel steel should be of equal shape and symmetry, without cracks, bubbles, cavities, or other defects that may compromise its quality;

(3)其他原材料不可以因具備難題造成 制成品抗壓強度的減少或危害其應用效率。

(3) Other raw materials should not cause a decrease in the compressive strength of the finished product or jeopardize its application efficiency due to difficulties.

2、風管和零配件表面整平、弧形勻稱、豎向接縫處應分開;咬口縫應密不可分，總寬勻稱。焊接應作外型查驗，不需有出氣孔、沙孔、焊瘤、裂痕等缺點，電焊焊接后厚鋼板的形變應糾正。

2. The surface of the air duct and spare parts should be leveled, the arc should be symmetrical, and the vertical joints should be separated; The bite joint should be inseparable and have a uniform overall width. Welding should undergo an external inspection, without any defects such as air vents, sand holes, weld beads, cracks, etc. The deformation of thick steel plates after welding should be corrected.

3、制做金屬材料風管和零配件，直徑或外面長的容許誤差，在其中制做法蘭，環形法蘭內徑或矩形框法蘭內邊規格容許誤差為+2㎜，不平度不可超過2㎜。

3. The allowable error for the diameter or outer length of metal material ducts and spare parts is+2mm, and the allowable error for the inner diameter of circular flanges or rectangular frame flanges is+2mm. The unevenness cannot exceed 2mm.

4、風管系統軟件內全部直角轉彎處均安裝消音彎管，消音彎管下設鍍鋅鐵板引流片。

4. All right angle bends in the air duct system software are equipped with silencing bends, and galvanized iron sheet drainage sheets are placed under the silencing bends.

5、與管路相關的土建施工經查驗達標，考慮安裝規定。

5. The civil construction related to pipelines has been inspected and found to meet the standards, and installation regulations have been considered.
