1. Izinto Eziyinhloko: Isingeniso ku-Ipayipi le-A335 P91 Alloy

A335 P91kuyintoinsimbi ye-ferritic alloyipayipi elihambisana ne-ASTM A335 standard. Ukwakheka kwayo okuyinhloko kwamakhemikhali yi-9% Chromium kanye ne-1% Molybdenum, kanye nokwengezwa okuncane kwe-Vanadium, Niobium, kanye ne-Nitrogen (yingakho igama layo lingu-P91). Ngenqubo yokwelapha ukushisa evamile neyokulinganisela, ifinyelela isakhiwo esincane esiyingqayizivele esinikeza izakhiwo zemishini ezingenakuqhathaniswa ngaphansi kwezimo zokushisa eziphezulu (kufika ku-600°C nangaphezulu) kanye nezimo zokucindezela okuphezulu. Uma kuqhathaniswa nendabuko.amapayipi ensimbi engxubevangenjenge-P22 noma i-P11, i-P91 ivumela izindonga ezincane ngengcindezi efanayo yokuklama, kunciphisa isisindo semishini, konga izindleko zezinto zokwakha, futhi kuthuthukiswe ukusebenza kahle kokushisa.

Amagama angukhiye: Ipayipi le-alloy,A335 P91,Insimbi ye-Chrome-Moly,Ipayipi Elishisa Kakhulu,Ipayipi Elingenamthungo,Amapayipi Amandla,I-ASTM A335

2. Imikhakha Ebalulekile Yokusetshenziswa Emakethe YaseNdiya

Izitshalo Zamandla Okushisa:Lolu uhlelo lokusebenza olukhulu nolubaluleke kakhulu lwe-P91amapayipi e-alloyeNdiya. Njengoba iNdiya icindezela ukwakhiwa kwamayunithi kagesi abaluleke kakhulu nabaluleke kakhulu ukuze kuthuthukiswe ukusebenza kahle futhi kuncishiswe ukukhishwa kwegesi, izinto ze-P91 sezibe yisinqumo esikhethwayo sazoimigqa eyinhloko yomusifuthiphinda ufudumale amapayipi ashisayoAmandla ayo okumelana nomusi wepharamitha ephezulu (ngokuvamile ingcindezi >22MPa, izinga lokushisa >560°C) libalulekile ekusebenzeni okuphephile nokuphumelelayo kwezitshalo zamandla.

Imboni Ye-Petrochemical:Ezindaweni zokucwenga kanye nezitshalo zamakhemikhali, amapayipi e-P91 asetshenziswa ezinyunithi ezibalulekile njengeUkuqhekeka Kwe-Fluid Catalytic (FCC)futhiAmayunithi okucubungula ngamanzi, ukuphatha uketshezi nama-hydrocarbon ashisa kakhulu, acindezela kakhulu, kanye nagonakalisayo.

 

Umkhakha Wamandla Enuzi:I-P91amapayipi ensimbi engxubevangethola izinhlelo zokusebenza ezinhlelweni ezithile ezisizayo zezitshalo zamandla enuzi, njengezinhlelo zokushisa ezishisa kakhulu, yize zingaphansi kwezidingo eziqinile kakhulu.

Eminye Imikhakha Yezimboni:Kufaka phakathi ukukhiqizwa kwamabhoyila, amapayipi esitofu sezimboni, kanye nezinhlobonhloboinqubo yokuhambisa amapayipiizinhlelo ezidinga izinga lokushisa eliphezulu kanye nokumelana nengcindezi.

 

3. Abashayeli Bemakethe Nezinselele

Abashayeli:

Isidingo Samandla:Umnotho waseNdiya okhula ngokushesha udala ukuntuleka okukhulu kwamandla kagesi, okwenza kube nokutshalwa kwezimali ezitshalweni zamandla ezintsha nezisebenza kahle.

 

Ukuthuthukiswa Kokusebenza Kahle:Ubuchwepheshe obugxile kakhulu buyindawo ebalulekile ekuthuthukisweni komkhakha wamandla eNdiya, okudala ngqo isidingo sezinto ezithuthukisiweamapayipi e-alloynjenge-P91.

Ukutshalwa Kwezimali Kwengqalasizinda:Ukutshalwa kwezimali okuqhubekayo kukahulumeni engqalasizinda yezimboni kanye namandla kunikeza umfutho wesikhathi eside emakethe.

Ukukhiqiza Kwendawo:Uhlelo lwe-"Make in India" lukhuthaza abakhiqizi bamapayipi basekhaya ukuthi bathuthukise amakhono obuchwepheshe ukuze bakhiqize ikhwalithi ephezuluamapayipi angenamthungo, ukunciphisa ukuncika ekungenisweni kwempahla.

 

Izinselele:

 

Izindleko Eziphezulu:Izinto zokusetshenziswa eziyinkimbinkimbi kanye nezinqubo zokukhiqiza ze-P91amapayipi e-alloykuphumela entengo ephakeme kakhulu kunepayipi lensimbi yekhabhoni elivamile.

Izidingo Eziqinile Zokushisela:Ukushisela amapayipi e-P91 kudinga ukushisisa kusengaphambili okuqinile, ukulawulwa kokushisa okuphakathi, kanye nokwelashwa kokushisa ngemva kokushisisa (PWHT). Kudinga ochwepheshe abanekhono eliphezulu, njengoba izinqubo ezingafanele zingaholela ekuhlulekeni.

Ukuthembela Kokungenisa:Nakuba umthamo wendawo ukhuphuka, amanye amapayipi e-P91 acacisiwe kakhulu asathembele ekungenisweni okuvela eYurophu, eShayina, njll.

Ukwehluka Kwekhwalithi:Ikhwalithi yomkhiqizo engaguquki emakethe yenza ukuqinisekisa ukuhambisana nokwakheka kwamakhemikhali, izakhiwo zemishini, kanye nezindinganiso zesimo sokwelashwa kokushisa kube yinto ebalulekile yokuphepha kwephrojekthi.

 

4. Umbono Wesikhathi Esizayo

Eminyakeni ezayo, njengoba i-India iqhubeka nokuthuthukisa amandla ayo okuphehla ugesi kanye nesisekelo sezimboni, isidingo sokusebenza kahle kakhuluamapayipi e-alloynjengeA335 P91kulindeleke ukuthi iqhubeke nokukhula okuzinzile. Izitayela zemakethe zizothambekela emikhiqizweni esezingeni eliphezulu nethembekile yendawo. Ngesikhathi esifanayo, kuzovela imakethe enkulu esekelayo yokuphathwa kwephayiphi impilo yonke, okuhlanganisa nezinsizakalo zokushisela kanye nokuhlolwa,. Abakhiqizi abakwazi ukuhlinzeka ngemikhiqizo ye-P91 esezingeni eliphezulu ehlangabezana nezindinganiso zomhlaba wonke (isib. i-ASTM, i-ASME) bazoba sesimweni esihle kule makethe yaseNdiya enamandla.
