Overview
Isu tinovimba nesimba rakasimba rehunyanzvi uye tinoramba tichigadzira matekinoroji echizvino-zvino kuti asangane nezvinodiwa neChina Mugadziri weASTM A335 Heat-Resisting Seamless Alloy Steel Pipe, Isu tinoisa pamberi kumhando yepamusoro uye kunakidzwa kwevatengi uye kune izvi isu tinotevera akaomesesa emhando yekudzora matanho. Isu tine zvivakwa zvekuyedza mukati memba umo zvigadziriso zvedu zvinoyedzwa pane chimwe nechimwe chinhu pamatanho akasiyana ekugadzirisa. Tine tekinoroji ichangoburwa, isu tinogonesa vatengi vedu neyakajairwa yekubuda nzvimbo.Zita rekambani, rinogara richienderana nemhando senheyo yekambani, kutsvaga budiriro kuburikidza nehukuru hwekuvimbika, kutevedzera ISO quality management standard, kugadzira kambani yepamusoro-soro mweya webudiriro-inocherekedza kuvimbika uye tariro.
Iko kunounzwa kweT91/P91 alloy simbi boiler pombi
1. Steel Giredhi Nhanganyaya
T91 / P91 isimbi inodzivirira kupisa, neiyo oak ridge yenyika murabhoritari muma1970 yakatanga kutsvagisa nekusimudzira, uye muna 1983 muASME, nyika yedu muna 1995 kusvika kusimbi muGB 5310 standard, mhando se10 cr9mo1vnbT91. / P91 simbi yaive 9 cr1mo (T9), pahwaro hwesimbi, kuchena, yakanaka crystallization metallurgy tekinoroji, pamwe neiyo micro alloying uye inodzorwa kukungurutswa uye inodzorwa kutonhora tekinoroji, yakagadzira chizvarwa chitsva chekupisa chisingachinji simbi alloy. Simbi ine yakanaka yakazara michina zvivakwa, tembiricha yakanyanya kuchembera mushure mekugadzikana, uye iyo welding performance uye process performance yakanaka, yakakodzera kune yakakwira tembiricha yekumanikidza chikamu chemidziyo.
