["Der Ventil für Flusschlor wird von Au供给商购买,含水量不确定。调节阀选用了316L阀体,阀芯和阀座波纹管选用了H. O.的材料。有没有问题?设备方面建议阀芯和阀座进行司太立堆焊处理,如果氯气含水量高的话,这个司太立耐不耐腐蚀?"

"St St立合金主要是耐高温腐蚀,对于湿氯腐蚀估计得向专业人士咨询。司太立合金太贵了,化工管阀件应用不多。"

"是的,只是阀杆和阀芯进行了堆焊处理。"

"St St立合金能够提高耐腐蚀性能。"

"对于调节阀阀座和阀杆头的硬化处理,一半使用了STL,STL的耐腐蚀能力与316L应该接近。"

"St St立合金属于钴基合金,整体耐磨性略好,阀内件表面堆焊处理后耐腐蚀能力也就316略强。液氯工况都是低压小口径,建议加内衬最好,成本最低。"

"不能用不锈钢的,会有化学反应。应选用铜材质或者衬氟的阀门。"

"阀内件用HC材质可以。司太立碰到氯离子使用效果不理想。楼主慎重。"

"感谢!!!阀体用316L没什么问题吧?怕外购液氯含水量问题有腐蚀。。。采购说是合格品是8sPPM以下含水率。"
Reply #102020-03-18
"最好不要用。从成本及使用效果考虑选个衬塑的稳妥。"
Reply #112020-03-18
"不客气。选衬塑阀门要注意使用压力问题。中高压环境用不了。"
