摘　　要：针对热网运行中管道严重锈蚀的问题,通过在热网工作条件下,试验比较不锈钢05X14C2、05X14C2b和3#碳素钢的锈蚀,证明采用碳素钢包覆1层05X14C2或05X14C2b号不锈钢制成的热网管道具有较高的耐锈蚀性,并且可以显著延长热网管道的使用寿命。Directed against the problem of serious corrosion inside pipes in heat net under operation, the comparative test results of stainless steel 05X14C2, 05X14C2b and 3^# under their working condition have proved that the pipe has higher corrosive resistance by using stainless steel 05X14C2 or 05X14C2 as inner layer. At the same time, the lifetime of those pipes will be prolonged.
