Seamless steel pipe ndi chingwe chachitali chachitali chokhala ndi chigawo chopanda kanthu komanso chopanda zopota. Chifukwa chapadera cha kupanga kwake, kumakhala ndi mphamvu zambiri komanso kukana kupanikizika kwabwino. Mipope yachitsulo yopanda msoko yomwe idayambitsidwa nthawi ino imaphatikizapo zida ziwiri ndi mawonekedwe: kalasi ya 15CrMoG, mawonekedwe 325 × 14 ndi12Cr1MoVGkalasi, specifications 325 × 10.

Makhalidwe ndi ntchito za15CrMoGchitoliro chachitsulo
15CrMoG ndi chitsulo cha chromium-molybdenum alloy, zigawo zikuluzikulu za mankhwala zomwe zimaphatikizapo carbon (C), chromium (Cr), molybdenum (Mo), ndi zina zotero. Nkhaniyi ili ndi mphamvu zambiri, kukana kwa okosijeni wabwino komanso kukana kutentha kwambiri, makamaka pa kutentha kwakukulu ndi malo othamanga kwambiri. Kuphatikiza apo, 15CrMoG ilinso ndi ntchito yabwino yowotcherera komanso kusinthika.

Ntchito
Mipope yachitsulo yopanda msoko yopangidwa ndi 15CrMoG imagwiritsidwa ntchito kwambiri pakutentha kwambiri komanso mapaipi othamanga kwambiri ndi zida, ndipo amagwiritsidwa ntchito kwambiri m'magawo otsatirawa:

Makampani opanga magetsi: ma boiler superheaters, reheaters, mitu ndi mapaipi akuluakulu a nthunzi m'mafakitale opangira magetsi.
Makampani a Chemical: makina opangira mapaipi amagetsi otenthetsera kwambiri pazida zamankhwala.
Makampani a petroleum: mapaipi otentha kwambiri komanso osinthanitsa kutentha m'malo oyeretsera.
Chitoliro chachitsulo ichi chikhoza kukhalabe ndi makina abwino kwambiri pa kutentha kwakukulu, ndipo ndichoyenera kwambiri kutentha kwa nthawi yayitali pakati pa 500 ° C ndi 580 ° C.
Makhalidwe ndi ntchito za 12Cr1MoVG mapaipi achitsulo
12Cr1MoVG ndi chitsulo chapamwamba kwambiri cha chromium-molybdenum-vanadium alloy chodziwika ndi mphamvu zambiri, kukana bwino kukwawa, komanso dzimbiri zolimba komanso kukana kwa okosijeni. Poyerekeza ndi 15CrMoG, imawonjezera kachulukidwe kakang'ono ka vanadium (V), yomwe imapangitsanso kukana kwake kutentha komanso kukhazikika.
Ntchito
Mapaipi achitsulo osasunthika opangidwa ndi 12Cr1MoVG nthawi zambiri amagwiritsidwa ntchito m'malo otentha kwambiri komanso opanikizika kwambiri, ndipo mawonekedwe ake amaphatikizapo:
Munda wamagetsi: zotenthetsera zotentha kwambiri, zotenthetsera ndi mapaipi m'mafakitale opangira magetsi otenthetsera ndi magetsi a nyukiliya.
Makampani a petrochemical: zida zotentha kwambiri komanso zopanikizika kwambiri ndi mapaipi.
Kupanga ma boiler: kupanga machubu otenthetsera kwambiri pazida zomwe zimakhala ndi zovuta zogwirira ntchito.
Chitoliro chachitsulo choterechi ndi choyenera kugwiritsidwa ntchito kwa nthawi yayitali pa kutentha kopitilira 570 ° C ndipo chimakhala ndi kukana kwamphamvu kwambiri komanso ductility.
Chitoliro chachitsulo cha 15CrMoG chokhala ndi mawonekedwe a 325 × 14 ndi chitoliro chachitsulo cha 12Cr1MoVG chokhala ndi mawonekedwe a 325 × 10 ali ndi zolinga zawo. Onsewa ndi mapaipi achitsulo osasunthika osasunthika ndipo amagwiritsidwa ntchito kwambiri m'mafakitale otentha kwambiri komanso othamanga kwambiri monga mphamvu, petrochemicals, ndi mankhwala. Malinga ndi chilengedwe ntchito, owerenga angasankhe bwino zitsulo chitoliro zakuthupi kukwaniritsa zofuna kupanga.
