Umgangatho ophezulu we-ASTM A335 P91 i-alloy engenamthungo yeSeel uMenzi wePipe eTshayina
Isishwankathelo
Uphuhliso lwethu luxhomekeke kwizixhobo eziphambili, iitalente ezigqwesileyo kunye nemikhosi yetekhnoloji eyomeleziweyo ngokuqhubekayo kumbhobho wethu wentsimbi womgangatho ophezulu womgangatho ophezulu, siya kuqhubeka sizama ukunyusa inkampani yethu kwaye sinikeze iimveliso ezisemgangathweni ezinoluhlu olunobundlongondlongo lwamaxabiso.Nawuphi na umbuzo okanye izimvo zixatyiswa kakhulu.Khumbula ukusibamba ngokukhululekileyo.Inkampani yethu isebenza ngomgaqo wokusebenza "wokusekwe kwintembeko, intsebenziswano eyenziweyo, ijolise kubantu, iphumelele intsebenziswano".Sinethemba lokuba sinokuba nobudlelwane bobuhlobo kunye nosomashishini abavela kwihlabathi liphela
I-P91 ayinayo kuphela ukuxhathisa okuphezulu kwe-oxidation kunye nobushushu obuphezulu bokumelana nokukhula komphunga, kodwa inefuthe elihle lokuqina kunye neplastiki ephezulu kunye nezinzileyo ehlala ixesha elide kunye namandla ashushu.Xa ubushushu benkonzo bungaphantsi kwe-620 ℃, uxinzelelo lwayo oluvumelekileyo luphezulu kunolo lwe-austenitic stainless steel.Ngaphezulu kwe-550 ℃, uyilo olucetyiswayo loxinzelelo oluvumelekileyo malunga nokuphindwe kabini kwe-T9 kunye ne-2.25Cr-1Mo yentsimbi.Ingasetyenziswa njengobushushu obuphezulu bobushushu obuphezulu kunye nombhobho wentsimbi wokufudumeza ubushushu bodonga lwebhoyila engaphantsi kunye ne-supercritical kwibhoyila ubushushu bodonga ≤625℃, iheader yobushushu obuphezulu kunye nobushushu bodonga lombhobho womphunga ≤600℃, kunye nesixhobo sokutshintsha ubushushu bamandla enyukliya kunye netyhubhu yesithando somlilo seyunithi yokuqhekeka kwepetroleum.
Isicelo
Isetyenziswa ikakhulu ukwenza umbhobho webhoyila wensimbi ekumgangatho ophezulu, umbhobho otshintshiselwa ngobushushu, umbhobho woxinzelelo oluphezulu wepetroleum kunye neshishini lemichiza.
IBanga eliPhambili
IBanga lombhobho we-alloy okumgangatho ophezulu:P1,P2,P5,P9,P11,P22,P91,P92 njl.
