I-ASTM A213 T5(ASME SA213 T5) iyishubhu yensimbi engenamthungo ephansi equkethe i-chromium engu-4.00–6.00% (Cr) kanye ne-molybdenum engu-0.45–0.65% (Mo), enikeza amandla amahle kakhulu okushisa okuphezulu kanye nokumelana nokugqwala, futhi isetshenziswa kakhulu emishinini yokushisa ephezulu, enomfutho ophezulu njengama-boiler, ama-superheater, kanye nama-heat exchanger.
Isikhundla se-UNS yi-K41545.
Ezingeni le-ASTM A213, ngaphezu kwe-T5, ama-alloy anokuqukethwe okufanayo kwe-chromium ne-molybdenum afaka i-T5b (UNS K51545) kanye ne-T5c (UNS K41245), ahluke kancane kuphela kokuqukethwe kwe-carbon, i-silicon, nezinye izakhi.
I-Botop Steel ingumthengisi wepayipi lensimbi ye-alloy ochwepheshe futhi othembekile eShayina, okwazi ukuhlinzeka ngokushesha amaphrojekthi akho ngamapayipi ensimbi ye-alloy alloy ahlukene, okuhlanganisaI-T9 (K90941),I-T11 (K11597),I-T12 (K11562),I-T22 (K21590), futhiI-T91 (K90901).
Imikhiqizo yethu isezingeni elithembekile, inentengo encintisanayo, futhi isekela ukuhlolwa komuntu wesithathu.

Umkhiqizi kanye Nesimo
Amapayipi ensimbi e-ASTM A213 T5 kumele enziwe yi-inqubo engenamthungofuthi kufanele kube yisiqedi esishisayo noma esibandayo, njengoba kuchaziwe.
Ukwelashwa Kokushisa
Amapayipi ensimbi e-T5 kufanele aphinde afudunyezwe ukuze kulungiswe ukushisa ngokwezindlela ezilandelayo, futhi ukwelashwa kokushisa kufanele kwenziwe ngokwehlukana futhi ngaphezu kokushisa ukuze kulungiswe ukushisa.

Ezinye zizoqina emoyeni, okungukuthi, ziqine ngezinga elingathandeki uma zipholile e-ạir ngenxa yokushisa okuphezulu, ikakhulukazi izinsimbi eziqukethe i-chromium ezine-chromium engu-4% nangaphezulu. Ngakho-ke, imisebenzi ehilela ukushisa izinsimbi ezinjalo ngaphezu kokushisa kwazo okubucayi, njengokushisela, ukufutha, kanye nokugoba okushisayo. kufanele kulandelwe ukwelashwa kokushisa okufanele.
Ukubukeka
Amashubhu ensimbi aqediwe nge-ASTM A213 ferritic alloy abandayo kufanele angabi nasikali futhi afanele ukuhlolwa. Inani elincane le-oxidation alibhekwa njengesikali.
Amashubhu ensimbi aqediwe nge-ferritic alloy ashisayo kufanele angabi naso isikali esixegayo futhi afanele ukuhlolwa.
Ubukhulu
Ubukhulu bamapayipi e-ASTM A213 T11 kanye nobukhulu bodonga ngokuvamile kufakwe ububanzi bangaphakathi obusukela ku-3.2 mm kuya kububanzi bangaphandle obungu-127 mm, kanye nobukhulu bodonga obuncane obusukela ku-0.4 mm kuya ku-12.7 mm.
Amanye amasayizi amapayipi ensimbi e-T11 nawo anganikezwa, uma nje zonke ezinye izidingo ze-ASTM A213 zihlangatshezwa.
Ipayipi ngalinye kufanele lihlolwe ngogesi ngendlela engabhubhisi noma ngokuhlolwa kwe-hydrostatic. Uhlobo lokuhlolwa oluzosetshenziswa luzokhethwa umenzi, ngaphandle uma kuchazwe ngenye indlela ku-oda lokuthenga.
Izinga le-ASTM A1016 livumela ukusetshenziswa kokuhlolwa okungonakalisi esikhundleni sokuhlolwa kwe-hydrostatic.
Amapayipi ensimbi angenamthungo e-ASTM A213 T5 asetshenziswa kakhulu ezinhlotsheni zezimboni ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu, kanye nokusebenza okuphawulekayo embonini yokuphehla ugesi, amakhemikhali, kanye ne-oyela negesi.
Izinhlelo zokusebenza ezijwayelekile zifaka phakathiamashubhu ebhoyila, amashubhu okushintshanisa ukushisa, amapayipi okucubungula amakhemikhali, izesekeli zebhoyila kanye nemikhumbi yokucindezela, kanye namapayipi okuthutha igesi eshisa kakhulu.
