Chitoliro chachitsulo chosasunthika cha ma boilers ndi mtundu wa chitoliro cha boiler ndipo ndi gulu la mapaipi opanda zitsulo. Njira yopangira ndi yofanana ndi mapaipi achitsulo osasunthika, koma pali zofunikira zokhwima za mtundu wazitsulo zomwe zimagwiritsidwa ntchito popanga mapaipi azitsulo. Mapaipi achitsulo osasunthika a boilers nthawi zambiri amagwiritsidwa ntchito pansi pa kutentha kwambiri komanso kupanikizika kwambiri. Pansi pa kutentha kwakukulu kwa gasi ndi nthunzi yamadzi, mapaipiwo amadzaza ndi oxidize. Mapaipi achitsulo amafunikira kuti akhale ndi mphamvu zokhalitsa, kukana kwambiri makutidwe ndi okosijeni ndi dzimbiri, komanso kukhazikika kwadongosolo. Mapaipi achitsulo osasunthika a ma boilers amagwiritsidwa ntchito kwambiri popanga mapaipi oponderezana kwambiri, mapaipi akuluakulu a nthunzi, ndi zina zambiri.

Machubu a boiler otsika komanso apakatikatiGB3087 ndimachubu opanda msokoGB5310 ndi zida zapamwamba zomwe zimagwiritsidwa ntchito popanga mapaipi otenthetsera kwambiri, mapaipi amadzi otentha opangira ma boilers otsika pang'ono amitundu yosiyanasiyana, mapaipi otenthetsera kwambiri opangira ma boilers, mapaipi akuluakulu a utsi, mapaipi ang'onoang'ono a utsi ndi mapaipi a njerwa. Mpweya wa carbon structural zitsulo zotentha-zotentha komanso zokokedwa (zopindika) zopanda msoko.Chitoliro chachitsulo chosasunthika (GB/T8162)ndi chitoliro chopanda chitsulo chomwe chimagwiritsidwa ntchito popanga zinthu zambiri komanso makina.Mapaipi opopera othamanga kwambiri ASME SA-106 (GR.B, GR.C)ndiASTM A210amagwiritsidwa ntchito popangira mapaipi opopera ndi ma boilers. Machubu, kuphatikiza machubu otetezera chitetezo ndi machubu a strut ndi machubu ang'onoang'ono amkati osasunthika opanda mpweya wazitsulo zamachubu apamwamba kwambiri,ASME SA-213, ferritic yopanda msoko komanso austenitic yama boilers, superheaters ndi heat exchanger Aloyi chitsulo chitoliro,Chithunzi cha ASTM A335 P5, P9, P11, P12, P22, P9, P91, P92, ferritic alloy opanda zitsulo chitoliro cha kutentha kwambiri.

Zofotokozera ndi maonekedwe: GB5310-2017 "Chitoliro Chopanda Chitsulo cha Maboiler Othamanga Kwambiri" M'mimba mwake ya kunja kwa mapaipi otentha ndi 22 mpaka 530mm, ndipo makulidwe a khoma amachokera ku 20 mpaka 70mm. Kunja kwa mapaipi okokedwa (ozizira-ozizira) amachokera ku 10 mpaka 108mm, ndipo makulidwe a khoma amachokera ku 2.0 mpaka 13.0mm.

Machubu opanda msoko a boilers amatengera zitsulo zachitsulo

(1) Makalasi apamwamba kwambiri a carbon structural zitsulo akuphatikizapo 20G, 20MnG, ndi 25MnG.

(2) Aloyi structural zitsulo zitsulo makalasi15 mog, 20MoG, 12CrMoG,15CrMoG, 12Cr2MoG, 12CrMoVG, etc.
