该耐磨管是经双金属复合耐磨钢板卷板加工而成,其最小直径可达∮200mm(而低于∮200mm的耐磨管是用耐磨管内壁堆焊机在Q235普通低碳钢管内直接堆焊而成),为什么说是叫双金属耐磨管呢,因为管外壁是普通碳素结构钢,具有很好的强性、可塑性和很好的焊接性;管内壁是高碳高铬成分,具有抗磨性。 The wear-resisting pipe is made of bimetal composite wear-resisting steel sheet. Its minimum diameter is up to 200 mm (while the wear-resisting pipe below 200 mm is made by direct surfacing in Q235 ordinary low-carbon steel pipe by the surfacing machine on the inner wall of the wear-resisting pipe). Why is it zhagunmj.37ix.com.cnqiangban.37ix.com.cnshengtaimu.37ix.com.cnbianyaqigs.37ix.com.cnmojuyz.37ix.c om.cnmojulbs.37ix.com.cncalled bimetal wear-resisting pipe, because the outer wall of the pipe is ordinary carbon structural steel and has good strength, plasticity and weldability? The inner wall is composed of high carbon and chromium, and has wear resistance. |
