煤矿井下用加强筋螺旋焊接镀锌钢管

    reinforced spiral welded galvanized steel

pipes in coal mining

压力等级：。抽放瓦斯气体管材最高公称压力-0.097mpa。
pressure grade: the maximum nominal pressure of the methane gas drainage pipes is -0.097mpa.

规格型号：dn300mm～dn1000mm。
specification and model: dn300mm～dn1000mm

执行标准： gb/t13912-2002《金属覆盖层钢铁制件热浸镀锌层 技术要求及试验方法》。

executive standard: gb/t13912-2002 metallic coatings — hot dip galvanized coatings for steel parts — technical requirements and test methods

性能特点：
performance features:

1.重量轻：同等规格型号管材，可减少70%的重量，劳动强度低，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.耐腐蚀：螺旋焊接波纹镀锌钢管是通过热镀锌工艺进行生产，锌层厚度高于国家标准对锌层厚度所做的要求，管道的防腐寿命长；

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.环刚度高：抽放瓦斯管材主要要求负压性能，此产品经过实验数据得出结论环刚度均满足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.锌层均匀：热浸镀锌的管材，锌层厚度均匀；

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

5.附着力强：镀锌钢带管采用热浸镀锌工艺处理，通过锤击法及锉刀法，锌层无起皮、剥落现象；

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：由于管材内壁光滑，无任何凸起，表面光滑度高，管道在运行中产生的噪音大大降低。

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.
