Yini uNace Mr0175?

UNace Mr0175, owaziwa nangokuthi "izidingo ezijwayelekile zezinto ezibonakalayo zokumelana nokuqhekeka kwengcindezi ye-sulfide ukuqhekeka ezindaweni zokucwengeka kaphethiloli ezilonakalisayo," kuyindinganiso ethuthukiswe yiNhlangano Yezezimali Yezwe Yokukhulisa (i-NACE) ukubhekana nodaba lwe-sulfide ukucindezelwa kwengcindezi ku-oyela futhi imboni yegesi. Leli Zinga lihlinzeka ngemikhombandlela yokukhethwa kanye neziqu zezinto ezisetshenziswayo kwemishini kanye nezakhi ezizovezwa ezindaweni ezonakalisayo ekusebenzeni kukaPetroleum.

I-Sulfide Stress Cracking (SSC) iyindlela yokuqhekeka okubangelwa yi-hydrogen okwenzeka ngensimbi namanye ama-alloys lapho evezwa i-hydrogen sulfide (H2S) kanye nengcindezi. Lolu hlobo lokuqhekeka lungaholela ekuhlulekeni okuyinhlekelele kwemishini futhi kubangethe ukuphepha okukhulu kanye nobungozi bezemvelo ekusebenzeni kwe-petroleum. UNace Mr0175 wathuthukiswa ukunciphisa ubungozi be-SSC ngokuhlinzeka ngezidingo zokukhethwa kanye neziqu zezinto ezivimbela ukuqhekeka kwengcindezi ye-sulfide ukuqhekeka.

I-Standard ihlanganisa izinhlobonhlobo zezinto zokwakha, kufaka phakathi i-carbon ne-all-alloy steel, ama-steres angenasici, ama-alloys ama-nickel, namanye ama-alloys alwa nokugqwala. Inika imihlahlandlela yokukhethwa kwezinto ezibonakalayo, ukwelashwa kokushisa, imikhawulo yobulukhuni, nezidingo zokuhlola ukuqinisekisa ukuthi izinto ezisetshenziswayo ezisetshenziswa ekuhlazisweni kwengcindezi ye-petroleum amelana nokuqhekeka kwengcindezi ye-sulfide ukucindezela.

Enye yezinto ezibalulekile zeNace MR0175 iyisiqu sezinto zokwakha ngokuhlolwa nemibhalo. Izindlela ezijwayelekile zichaza izidingo ezithile zokuhlola, njengokuhlola kanzima, ukuhlolwa okuthe xaxa, nokuhlolwa kokuqhekeka kokuqhekeka kwengcindezi, ukukhombisa ukumelana kwezinto zokwakha ukuqhekeka kwengcindezi ye-sulfide ukucindezela kwengcindezelo. Ngaphezu kwalokho, amazinga adinga abakhiqizi ukuthi banikeze imibhalo, efana nemibiko yokuhlolwa kwezinto ezibonakalayo kanye nezitifiketi zokuhambisana, ukuqinisekisa ukuthi izinto zokwakha zihlangabezana nezidingo zeNace Mr0175.

UNace Mr0175 futhi uhlinzeka nezinkombandlela zokwakheka kanye nokwakhiwa kwemishini nezinto ukunciphisa ingozi yokuqhekeka kwengcindezi ye-sulfide ukucindezela. Lokhu kufaka phakathi izincomo zezinqubo ze-welding, ukwelashwa okungaphezulu, nezinye izindlela zokuvimbela ukuqhekeka okubangelwa yi-hydrogen enkundleni.

Ukuhambisana neNace Mr0175 kubalulekile ekuqinisekiseni ubuqotho kanye nokwethenjwa kwemishini nezinto eziku-Petroleum Refining Operations. Ngokukhetha kanye nezinto ezifanelekile zokwenziwa ngokuya ngeZinga, abahlinzeki banganciphisa ubungozi bokuqhekeka kwengcindezi ye-sulfide ukucindezela futhi kuqinisekiswe ukuphepha nokusebenza kwezikhungo zabo.

Ekuphetheni, uNace Mr0175 uyindinganiso ebucayi embonini kawoyela negesi, ukuhlinzeka izinkombandlela zokukhethwa kanye neziqu zezinto zokwakha ezivimbela ukucindezelwa kwengcindezi ye-sulfide ecindezelayo ezindaweni zokucwilisa uPetrolise Ngokulandela izidingo zaleli Zinga, opharetha banganciphisa ingozi yokuqhekeka kwengcindezi ye-sulfide ukucindezela futhi baqinisekise ubuqotho kanye nokwethenjwa kwemishini yabo kanye nezinto zabo. Ukuhambisana neNace Mr0175 kubalulekile ekugcineni ukuphepha kanye nokusebenza kahle kwemisebenzi yokucwengelwa kwe-petroleum.

I-Hikelok ingahlinzeka ngemikhiqizo ehlukahlukene evumelana neNace MR0175 Standard, njengeTube Fittings, Ukufakwa kwamapayipi, Ama-valve ebhola, Ama-valves anayo, Bheka ama-valves, Ama-valves okusiza, Amasilinda wesampula.
