煤礦井下用螺旋焊接波紋鍍鋅鋼管

? ??Spiral welded corrugated galvanized steel pipes in coal mining?

壓力等級:抽放瓦斯氣體管材,最高公稱壓力-0.097MPa。
Pressure grade: the maximum nominal pressure of the methane gas drainage pipes is -0.097MPa.

規格型號:DN200mmDN800mm。
Specification and model: DN200mmDN800mm

執行標準: GB/T13912-2002《金屬覆蓋層 鋼鐵制件熱浸鍍鋅層?技術要求及試驗方法》。

Executive standard: GB/T13912-2002 Metallic Coatings Hot Dip Galvanized Coatings for Steel Parts Technical Requirements and Test Methods.

性能特點
Performance features:

1.重量輕:相對于同等規格型號的其他管材,此種管材大大減少了管材重量,使得勞動強度低,施工效率較快;

1. Light weight: compared with other pipes with the same specification and model, this kind of pipes greatly reduces the weight of the pipe, which makes the labor intensity low and the construction efficiency relatively fast;

2.耐腐蝕:螺旋焊接波紋鍍鋅鋼管是通過熱鍍鋅工藝在螺旋焊接波紋鋼管表面鍍上一層鍍鋅層,鋅層厚度高于國家標準對鋅層厚度所做的要求,管道的防腐壽命優于一般涂層防腐材料;

2. Corrosion resistance: spiral welded corrugated galvanized steel pipe is coated with a galvanized layer on the surface of spiral welded corrugated steel pipe by hot-dip galvanizing process. The thickness of zinc layer is higher than the requirements in national standards for the thickness of zinc layer. The corrosion resistance lifetime of the pipeline is better than that of the general coating anti-corrosive material;

3.環剛度高:抽放瓦斯管材主要要求負壓性能,此產品經過實驗數據得出結論環剛度均滿足SN16;

3. High ring stiffness: the main requirement of the methane gas drainage pipes is the negative pressure performance. The experimental data shows that the ring stiffness meets SN16;

4.鋅層均勻:熱浸鍍鋅的管材,鋅層厚度均勻,包覆完整;

4. Uniform zinc layer: hot dip galvanized pipes have the uniform thickness of the zinc layer and the complete coating;

5.附著力強:鍍鋅鋼帶管采用熱浸鍍鋅工藝處理,通過錘擊法及銼刀法,鋅層無起皮、剝落現象。

5. Strong adhesion: the galvanized steel strip pipes are treated by hot dip galvanizing process. Through the hammering method and the file method, the zinc layer has no peeling.
