步驟一：若覺得風管較短，可一次在地面組裝而成，當風管較長時，可在地面上分段組裝。裝配過程中應盡可能調(diào)整風道度和水平度，避免風管扭曲或上下波動，左右擺動，每段風道不宜超過10 m.在裝配時，墊片應墊平，螺栓應均勻地緊固，螺帽朝向同一方向。
Step 1: If the air duct is short, it can be assembled at one time on the ground. When the air duct is long, it can be assembled in sections on the ground. In the process of Assembly, the center degree and level degree of the air duct should be adjusted as far as possible to avoid the distortion or fluctuation of the air duct. In the assembly, the gasket should be flat, bolts should be tightened evenly, nuts toward the same direction.

步驟二：山東通風管道加工提醒你安裝前應檢查所有支架的水乎度、標高、檢查支架是否牢固，風管就位可采用直立和吊具兩種方式。對于截面較小、位置較低的風管，可以采用手動就位的方法，只需搭搭簡易腳手架。風管截面較大，管段較長時，可用滑輪、倒鏈、大繩等方式吊裝。
Step 2: Shandong Ventilation pipe processing remind you to check all support before installation of water, elevation, check whether the support is solid, duct in place can be used vertical and lifting two ways. For the duct with smaller cross-section and lower position, the method of manual positioning can be adopted. When the cross-section of the air duct is large and the pipe section is long, it can be lifted by means of Pulley, chain and rope.
目前山東通風管道加工采用風道懸掛在腳手架上，然后抬高到風道支架上，以便安裝到位。腳手架應沿其風道長度方向搭設(shè)，高度和位置應適合施工操作，升降順序應先干后支、立管，吊起時，吊點應牢固，兩吊點應均勻受力。垂直風管可采用人工、繩索輔助安裝。調(diào)整管道，確保滿足垂直要求。

The duct is suspended from the scaffold and then raised to the duct bracket for proper installation. Scaffold should be set up along the direction of its air duct length, height and position should be suitable for construction operation, lifting sequence should first dry after the branch, vertical pipe, lifting point should be firm, two lifting point should be evenly stressed. The vertical air duct can be installed manually and with the aid of rope. Adjust piping to ensure vertical requirements.
