　　2. Ji'nan ventilation pipe project in the first closed valve to the mouth of the pipe and fittings should be welded by thick 2-3mm steel plate, the weld should be full, uniform, tight.

　　3.工程测压管在防护密闭门外的一端应设有往下的弯头，另一端宜设在通风机房或控制室，并应安装球阀。通过防毒通道的测压管，其接口应采用焊接。

　　3. the pressure measuring pipe of the project shall be provided with a downward elbow at one end of the protective airtight door, and the other end shall be arranged in the ventilation room or the control room, and the ball valve shall be installed. Through the measuring tube of the gas passage, the interface shall be welded.

　　4.染毒区的通风管道应采用焊接连接。通风管道与密闭阀门应采用带密闭槽的法兰连接，其接触应平整;法兰垫圈应采用整圈无接口橡胶密封圈。

　　4. the ventilation duct in the contaminated area shall be welded. The ventilation pipe and the airtight valve should be connected with flange with airtight groove, and the contact should be smooth. The flange washer should adopt the whole circle without interface rubber sealing ring.

　　5.通风管的测定孔.洗消取样管应与管同时制作。测定孔和洗消取样管应封堵。

　　5. determination holes for ventilation pipes. Wash out sampling tubes shall be made simultaneously with tubes. The measuring hole and the decontamination sampling tube shall be sealed.

　　6. 主体工程内通风管与配件的钢板厚度应符合设计要求。当设计无具体要求时，钢板厚度应大于0.75mm。

　　6. the thickness of the steel plate of the ventilation pipe and fittings shall comply with the design requirements. When the design has no specific requirements, the steel plate thickness should be greater than 0.75mm.

　　法兰用料应分类码法放，露天防止应采取防雨、雪措施.减少生锈现象。通风管道应码放在平整无积水，宽敞的场地，码放时应按系统编号，整齐、合理、便于装运。

　　Flange material should be classified code method, open to prevent rain and snow measures should be taken to reduce the phenomenon of rust. The ventilation pipe should be stacked without water in the flat, spacious venues should be stacked according to system number, orderly, reasonable and convenient for shipment.

　　还需要注意在涂漆时应使漆膜均匀，不得有堆积、漏涂、皱纹、气泡及混色等缺陷。普通钢板在压口时必须先喷一道防锈漆，保证咬缝内不易生锈。

　　It should also be noted that the paint film should be made even, without any defects such as accumulation, leakage, wrinkles, bubbles and mixed colors. Ordinary steel plate must be sprayed at the mouth of a rust proof paint, to ensure that the joints are not easy to rust.

　　要保持镀锌钢板表面光滑洁净，放在宽敞干燥的隔潮木头 垫架上，叠放整齐。不锈钢板、铝板要里靠在木架上，不要平迭，以免拖动时刮伤表面，下料时应使用不产生划痕的划线工具。操作时应使用木锤或有橡胶皮套的锤子，不得使用铁锤，以免落锤点产生锈斑。

　　To keep the galvanized steel surface smooth and clean, put on the spacious dry wooden shelf, stacked neatly. Stainless steel plate, aluminum plate to depending on the gallows, not flat, so as not to drive when scratching the surface, should use the scribing tool does not produce scratches when feeding. The operation should use wooden hammer or rubber leather hammer, hammer shall be used, so as not to drop point rust.
