【中英文】不銹鋼金屬軟管安裝說明

安裝的關鍵因素

Following advises are however to be taken into consideration in order to obtain a good performance and prolonged of the expansion joint.

注意：為了獲得良好的性能和延長伸縮縫的使用壽命，必須考慮以下建議。

Fixed points

固定點

An expansion joint acts as a piston by the forces arising from the internal pressure.To prevent the pipes from damage they are to be properly anchored in order to take care of these reaction forces (Fr).

金屬軟管由內部壓力產生的力作用于活塞，為了防止管道受到損壞，必須將管道固定起來，以處理這些反作用力（FR）。

The Reaction force of an expansion joint is calculated by the following formula:

金屬軟管的反力計算公式如下：

Fr = Q x P x 0.01

Fr = reaction force in kN.

Q = effective cross sectional area in cm2.

P = actual pressure in bar or kp/cm2

Mounting

安裝

Before installation, the temperature, pressure and displacement of the product should be strictly used.

安裝前應嚴格在產品允許的溫度、壓力和位移量范圍內使用！

The expansion joints shall be easily accessible and open to regular supervision. Lt is recommended to let the expansion joints work in compression rather than stretching. Torsion is not permitted.

金屬軟管應很容易的定期檢查。我建議金屬軟管的工作是壓縮，而不是拉伸，更不允許扭轉。

Maintenance instructions: observe whether the expansion jointt is over stretched and keep the expansion joint in normal length every month.

保養(yǎng)須知：每月要觀察金屬軟管是否超位移拉長，保持金屬軟管在正常長度內使用。

In order to ensure the expansion capacity, the bolts should be kept as small as possible (not exceeding 2 mm or 3mm) to avoid damaging the metal hose body.

為了保證伸縮能力，裝配螺栓要確保螺紋螺栓盡量少（不超過2毫米或3mm），以避免損壞金屬軟管本體。

Precaution

預防措施

When welding work is to take place the bellow has to be protected from welding heat and sparks.

當焊接工作發(fā)生時，金屬軟管本體必須防止焊接發(fā)熱和火花。

Please install an effective chlorine removal device at the inlet of the pipeline (chloride content is not more than 25mg/l) to avoid excessive chlorine content and pinhole corrosion.

請在管道進水口加裝有效去除氯離子裝置（氯離子含量不超過25mg/l），避免水氯離子含量超標，產生針孔腐蝕。
