Lub txim ntawm kev ua haujlwm tsis zoo ntawm cov khoom siv hlau uas siv rau cov roj thiab cov khoom siv roj ua rau lawv raug H 2 S- cov kua dej muaj zog tuaj rau hauv kev loj hlob ntawm NACE mr0175 THIAB tom qab EFC Ntawv qhia 16 [15] NACE MR0175 / ISO 15156-1 [ 20] thiab -2 yog tsim los siv cov kev pabcuam los muab cov kevcai thiab cov lus pom zoo rau cov ntaub ntawv tsim nyog thiab xaiv rau kev siv hauv cov cheebtsam uas muaj ntub H 2 S hauv cov roj thiab cov khoom siv roj. Cov roj carbon thiab cov hlau tsis muaj hlau uas siv cov ISO 15156-2 yog cov kabmob ua rau ntu H 2 S uas muaj qhov chaw nyob hauv cov roj thiab cov roj ntau lawm, tab sis tsis tas ua kom tawg rau hauv tag nrho cov kev pabcuam. Cov kev pabcuam sib txawv kuj yuavtsum tau sim lwm qhov kev xeem uas yog muab tso rau hauv ISO 15156-2: 2003, Annex B. Lub tsev txuas ntxiv qhia tias yuavtsum tau muaj cov pa roj carbon tsawg thiab cov hlau tsis zoo rau H 2 S cov kev pabcuam los ntawm kev kuaj sim.
Nws yog tus neeg yuav khoom lub luag haujlwm los xaiv cov roj thiab qis-alloy steels rau qhov kev pab cuam uas tau npaj tseg

HIC / SSC xeem
Kev ntsuas rau kev ntsuam xyuas ntawm kev ua haujlwm-ua rau tawg nti uas tau ua kom huam tuaj yog tsim nyog raws li cov kev lees txais hauv qab no, nrog rau txhua qhov piv txwv uas yog qhov siab tshaj plaws rau peb seem ntawm ib qho kev kuaj kev kuaj thaum kuaj hauv qhov (Environment) A (saib ISO 15156-2: 2003, Cov lus B.3):
a) tawg rhiab ratio (CSR) ≤ 2%;
b) tawg ntev piv (CLR) ≤ 15%;
c) tawg tuab qhov sib piv (CTR) ≤ 5%;
Yog tias HIC / SSC cov kev ntsuam xyuas raug tshawb fawb ntawm lwm txoj hauv kev, tawm hauv xov xwm los sim cov kev pabcuam tshwj xeeb, kev lees txais lwm yam yuav raug pom zoo.

Hardness xeem
Rau kev xeem cov kev kuaj mob, qhov nyuaj hauv lub cev, qhov txuas thiab HAZ yuav tsum yog ≤ 250 HV10 lossis 22 HRC (70,6 HR 15N).
Qhov siab tshaj plaws ntawm qhov chaw uas tsis muaj qhov sib xyaw thiab lwm qhov HAZ thiab lub hauv paus hlau tej zaum yuav 275 HV10 los yog 26 HRC (73,0 HR 15N) uas tus neeg siv khoom siv pom zoo rau qhov kev hloov ntawm qhov tsis sib xws, tshaj li 9 hli, lub hau ntim tsis kis ncaj qha rau qaub thaj chaw thiab kev khiav dim ntawm hydrogen tsis yog kev tiv thaiv, xws li kev tiv thaiv cathodic.
