Isingeniso somkhiqizo

Incazelo Yomkhiqizo
Ipayipi le-astm a335 P91 liyipayipi elingenamthungo elenzelwe ukusetshenziswa kwezinga lokushisa eliphezulu. Lawa mapayipi enziwe nge-ferritic Alloy-Steel.
Ngokwekhemikhali ipayipi elishiselwe i-a335 P91 liqukethe izakhi ezifana ne-Molybdenum (Mo) ne-Chromium engezwe ku-alloy. Lapho i-Molybdenum
futhi i-chromium yengezwa ku-alloy, kukhona ukwanda kwamandla e-tensile wepayipi le-sa335 grade P91. Amandla aqinile we
ipayipi le-a335 grade P91 liyi-415 Mpa, kanti amandla ayo okukhiqiza angu-205 Mpa. Iphesenti lokwelulwa kwepayipi liphakathi kuka-20% kuya ku-30%.
I-Alloy Steel P91 Amapayipi Angenamthungo avame ukubizwa ngokuthi yinsimbi enhle kakhulu ngenxa yokwanda kokumelana nokugqwala kwe-chloride okuyenza ibe yinhle kakhulu.
izinto ezifanele ukusetshenziswa ezindaweni zamanzi anosawoti.
