Attention should be paid to PVC flame retardant air duct before construction and handling
1、施工图纸及其他技术文件齐全，且已进行图纸技术交底，满足pvc阻燃风管施工要求;
1. The construction drawings and other technical documents are complete, and the technical disclosure of drawings has been carried out to meet the construction requirements of PVC flame retardant air duct;
2、施工人员应经过建筑管道安装的技术培训，能够熟练的对pvc阻燃风管在施工过程中的常见问题进行分析处理。
2. The construction personnel shall have the technical training of building pipeline installation, and be able to skillfully analyze and deal with the common problems of PVC flame-retardant air duct in the construction process.
3、施工方案、技术、材料等能保证pvc阻燃风管的正常施工。
3. The construction scheme, technology and materials can ensure the normal construction of PVC flame-retardant air duct.
pvc阻燃风管在储藏搬运过程中需要注意：
Attention shall be paid to PVC flame-retardant air duct during storage and handling:
1、pvc阻燃风管材应水平堆放在平整的地上，应避免弯曲管材，堆置高度不得超过1.5m，管件应逐层码堆，不宜叠得过高。
1. PVC flame-retardant wind pipes shall be stacked horizontally on flat ground, bending pipes shall be avoided, stacking height shall not exceed 1.5m, pipe fittings shall be stacked layer by layer, not too high.
2、管材和管件应放在通风******的库房或简易棚内，不得露天存放，防止阳光直射，注意防火安全，距离热源不得小于1m。
2. Pipes and pipe fittings shall be placed in a well ventilated warehouse or simple shed, and shall not be stored in the open air, to prevent direct sunlight, pay attention to fire safety, and the distance from the heat source shall not be less than 1 m.
3、搬运管材和管件时，应小心轻放，避免油污，严禁剧烈撞击，严禁与尖锐物品碰触和抛、摔、滚、拖。pvc阻燃风管道在施工过程中要确保提供的pvc阻燃风管管材和管件应符合设计规定，并附有产品说明书和质量合格证书。在使用前一定要对pvc阻燃风管进行技术鉴定或者复检，杜***使用质量有异有损坏迹象的管材。
3. When handling pipes and pipe fittings, handle them with care to avoid oil pollution, and avoid violent impact. It is strictly prohibited to touch sharp objects and throw, fall, roll and drag them. During the construction of PVC flame-retardant air duct, it is necessary to ensure that the PVC flame-retardant air duct pipes and pipe fittings provided shall conform to the design requirements, with product instructions and quality certificates attached. Before use, it is necessary to carry out technical appraisal or re inspection on PVC flame-retardant air duct to prevent the use of pipes with different quality and signs of damage.
pvc阻燃风管施工过程中设置方式pvc阻燃风管材管道敷设形式的不同产生了伸缩节设置和管套设置两种设置方式。
In the process of PVC flame-retardant air duct construction, there are two ways to set expansion joint and pipe sleeve.
