Ventilation ducts in Jinan City

制做前的准备工作：

Preparation work before production:

1、制做风管前，要查验选用的原材料是不是合乎品质规定，是不是有产品合格证明书或品质评定文档。若济南市通风管道无所述证明材料则应开展外型查验，并应合乎以下规定：

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)板才表面应整平，薄厚应匀称，无凹凸及显著的挤伤状况，并不可有裂痕、沙孔及、刺边和生锈状况;

(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)槽钢应当等型、匀称，不需有裂痕、汽泡、窝穴以及它危害品质的缺点;

(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备难题造成 制成品抗压强度的减少或危害其应用效率。

(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、风管和零配件表面整平、弧形匀称、竖向接缝处应分开;咬口缝应密不可分，总宽匀称。焊接应作外型查验，不需有出气孔、沙孔、焊瘤、裂痕等缺点，电焊焊接后厚钢板的形变应纠正。

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、制做金属材料风管和零配件，直径或外面长的容许误差，在其中制做法兰，环形法兰內径或矩形框法兰内边规格容许误差为+2㎜，不平度不可超过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、风管系统软件内全部直角转弯处均安裝消音弯管，消音弯管下设镀锌铁板引流片。

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、与管路相关的土建施工经查验达标，考虑安裝规定。

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