pvc阻燃風管在儲藏搬運過程中需要注意：

Attention shall be paid to PVC flame-retardant air duct during storage and handling:

1、pvc阻燃風管材應水平堆放在平整的地上，應避免彎曲管材，堆置高度不得超過1.5m，管件應逐層碼堆，不宜疊得過高。

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、管材和管件應放在通風******的庫房或簡易棚內，不得露天存放，防止陽光直射，注意防火安全，距離熱源不得小于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、搬運管材和管件時，應小心輕放，避免油污，嚴禁劇烈撞擊，嚴禁與尖銳物品碰觸和拋、摔、滾、拖。pvc阻燃風管道在施工過程中要確保提供的pvc阻燃風管管材和管件應符合設計規定，并附有產品說明書和質量合格證書。在使用前一定要對pvc阻燃風管進行技術鑒定或者復檢，杜***使用質量有異有損壞跡象的管材。

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阻燃風管施工過程中設置方式pvc阻燃風管材管道敷設形式的不同產生了伸縮節設置和管套設置兩種設置方式。

In the process of PVC flame-retardant air duct construction, there are two ways to set expansion joint and pipe sleeve.
