煤礦井下用加強筋螺旋焊接鍍鋅鋼管

? ? Reinforced spiral welded galvanized steel

pipes in coal mining


壓力等級:彩票365下载。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:dn300mmdn1000mm。
Specification and model: dn300mmdn1000mm

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:同等規格型號管材,可減少70%的重量,勞動強度低彩票365下载,施工效率快;

1. Light weight: compared with other pipes with the same specification and model, the weight is reduced by 70%; the labor intensify is low and the construction efficiency is fast;

2.耐腐蝕:螺旋焊接波紋鍍鋅鋼管是通過熱鍍鋅工藝進行生產,鋅層厚度高于國家標準對鋅層厚度所做的要求彩票365下载,管道的防腐壽命長;

2. Corrosion resistance: the spiral welded corrugated galvanized steel pipe is produced 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 long;

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,鋅層厚度均勻彩票365下载;

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

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;

6.噪音低:由于管材內壁光滑,無任何凸起,表面光滑度高,管道在運行中產生的噪音大大降低。

6. Low noise: since the inner wall of the pipe is smooth with no protrusion, the surface smoothness is high, thus the noise generated by the pipeline during operation is greatly reduced.

規格尺寸:煤礦井下用加強筋螺旋焊接鍍鋅鋼管規格尺寸符合下表要求
