Ipayipi lensimbi ye-alloy P22(Ibanga A335 P22, impahla engu-2.25Cr-1Mo) iyinsimbi ye-alloy engashisi i-chromium-molybdenum esetshenziswa kabanzi. Ngenxa yamandla ayo aphezulu okushisa, ukumelana okuhle kokuqhekeka, kanye nokumelana nokushiswa kwe-oxidation, idlala indima ebalulekile emikhakheni eminingana ebalulekile yezimboni emakethe yaseNdiya.

Izindawo Eziyinhloko Zokusebenza Zifaka:

Ukukhiqizwa Kwamandla (Isicelo Esiyinhloko):

Izitshalo Zamandla Okushisa: Ziyinto ebalulekile kuma-boiler kumayunithi angaphansi kwe-subcritical kanye namanye angaphansi kwe-supercritical. Zisetshenziswa kakhulu ekukhiqizeni amashubhu e-superheater, amashubhu okuvuselela, amapayipi amakhulu omusi, kanye nama-header okushisa okuphezulu. Njengoba i-India iqhubeka nokwandisa ingqalasizinda yayo yamandla ukuze ihlangabezane nezidingo zokukhula komnotho, ukusetshenziswa kweIpayipi le-P22kulo mkhakha usazinzile.

Ukuhlaziya nokulungisa amakhemikhali:

Isetshenziswa ekukhiqizeni amapayipi enqubo yokushisa okuphezulu kwamayunithi okucubungula amanzi e-refinery, amayunithi okuqhekeka kwe-catalytic, amashubhu okushintshanisa ukushisa, kanye namapayipi ahambisa imifudlana kawoyela negesi eshisa kakhulu. Ukumelana kwayo nokuhlasela kwe-hydrogen eshisa kakhulu kanye nokugqwala kwesulfure kuyenza ifaneleke ezindaweni ezinzima ze-petrochemical.

Imboni Yomanyolo:

Kusetshenziswa ezitshalweni ezikhiqiza i-ammonia, i-urea, njll., ekufakeni amapayipi egesi kanye nemishini ngaphansi kokushisa okuphezulu kanye nengcindezi, njengepayipi le-reformer kanye ne-waste heat boiler.

Ezinye Izimboni:

Iphinde isetshenziswe kuma-boiler ezimboni, kuma-heat exchangers, kanye nasezitsheni ezahlukahlukene zokucindezela ezisebenza emazingeni okushisa aphezulu (ngokuvamile cishe ngo-550°C-600°C).

Izici Zemakethe YaseNdiya:

Abashayeli Besidingo: Isidingo siqhutshwa kakhulu amaphrojekthi kagesi asekhaya (ukwakhiwa okusha nokulungiswa kabusha), ukwandiswa kwamandla okuhlanza, kanye nokukhula kwezimboni eziyisisekelo.

Imithombo Yokunikezwa: Imakethe ihlinzekwa yizinto zokungenisa (ikakhulukazi ezivela eShayina, eJapane, eYurophu, njll.) kanye nabakhiqizi basekhaya baseNdiya (isb., i-ISMT), okuholela ekuncintisaneni okukhulu. Intengo, ikhwalithi, isikhathi sokulethwa, kanye nensizakalo yendawo yizici ezibalulekile zokuncintisana.

Izindinganiso Nesitifiketi: Amaphrojekthi ngokuvamile alandela amazinga e-ASME/ASTM futhi angadinga nokuhambisana nezindinganiso zase-India noma izincazelo ezithile zephrojekthi. Ukuthola izitifiketi ezifanele (isb., ezihlobene ne-IBR - Imithethonqubo Yebhoyila YaseNdiya) kubalulekile ekungeneni emakethe.

Izinselele Nemikhuba: Ibhekene nokuncintisana okuvela ezintweni ezisezingeni eliphezulu (isb., i-P91/P92) kumayunithi epharamitha ephezulu kanye nezingcindezi zezindleko. Kukhona ukugcizelela okukhula kwemakethe ekhwalithini yomkhiqizo, ukuthembeka, kanye nokuzinza kochungechunge lokuhlinzekwa.

Ngamafuphi, ipayipi lensimbi ye-alloy P22 liyinto eyisisekelo yezimboni eziyinhloko ezifana namandla kanye namakhemikhali e-petrochemicals eNdiya. Nakuba inselele ngezinto ezintsha zobuchwepheshe, ukuthembeka kwayo okuqinisekisiwe, ukusebenza kahle kwezindleko, kanye nokufaneleka kokugcinwa, ukulungiswa kabusha, kanye namaphrojekthi amaningi okushisa okuphakathi kuya phezulu kuqinisekisa ukuthi izogcina isabelo semakethe esizinzile nesibalulekile esikhathini esizayo esibonakalayo.
