铸铁管爆管造成的事故损失 ,在全国屡见不鲜。近几年大面积推广的球墨铸铁管 ,也有爆管发生。笔者长期工作在企业基层 ,对铸铁管因排气不畅引起的爆管原因有一新点新认识。当铸铁管第一次试送水 ,或长期不送水恢复送水时 ,要注意管内积存气体的排除 ,要想避免不爆管 ,必须保证 Cast iron pipe explosion caused by accident loss, common in the country. In recent years, large-scale promotion of ductile iron pipe, burst pipe also occurred. I long-term work in the grass-roots enterprises, cast iron pipe due to poor exhaust pipe burst caused a new understanding of the reasons. When the first test of cast iron pipe water, or long-term non-return water, pay attention to the exclusion of accumulated gas pipe, in order to avoid non-pipe explosion, we must ensure that
