20G:GB5310-95 kugamuchirwa mwero simbi (yekunze giredhi inoenderana: Germany's ST45.8, Japan's STB42, United States SA106B), ndiyo inonyanya kushandiswa bhoiler simbi pombi, kemikari uye mechanical zvimiro uye 20 ndiro yakangofanana. Simbi ine simba rakati pakamuri tembiricha uye yepakati tembiricha yakakwira, yakaderera kabhoni yemukati, zviri nani plastiki uye kuomarara, kupisa kwayo uye kutonhora kuumba uye kuita welding kwakanaka. Inonyanya kushandiswa mukugadzira high pressure uye yakakwirira parameters ye boiler fittings, yakaderera tembiricha chikamu superheater, reheater, economizer uye mvura madziro, etc. Zvakadai sediki dhayamita pombi madziro tembiricha ≤500 ℃ kudziyisa pamusoro pepombi, uye mvura madziro pombi, economizer chubhu, hombe dhayamita pombi madziro tembiricha ≤450 ℃ chiutsi pombi, kuunganidza bhokisi (economizer, mvura madziro, yakaderera tembiricha superheater uye reheater coupling bhokisi), tembiricha yepakati ≤450 ℃ pombi zvishandiso. Nekuti kabhoni simbi inoburitsa graphitization mukushanda kwenguva refu pamusoro pe450 ℃, saka tembiricha yenguva refu yekupisa yepombi yekudziya inogumira pazasi 450 ℃. Simbi iri mune ino tembiricha renji, simba rayo rinogona kusangana nezvinodiwa zve superheater uye pombi yehutsi, uye ine yakanaka oxidation kuramba, plastiki, kuoma, welding zvivakwa uye zvimwe zvinotonhora uye zvinopisa zvekugadzirisa zvinhu zvakanaka kwazvo, zvakashandiswa zvakanyanya. Zvikamu zvesimbi inoshandiswa muchoto cheIran (zvichireva seti imwe chete) ipombi yekupinza mvura (matani makumi maviri nemasere), pombi yekupinza mvura (matani makumi maviri), pombi yekubatanidza chiutsi (26 matani), mudziyo wehupfumi (8). matani), uye nzira yekudzikisa mvura (matani mashanu), uye mamwe anoshandiswa sesimbi yakatsetseka uye derrick zvinhu (anenge 86 matani).

Sa-210c (25MnG) : Nhamba yesimbi mukatiASME SA-210standard. Iyo idiki dhayamita chubhu yekabhoni manganese simbi yemaboilers uye superheaters, uye inopisa simba simbi ine pearl chimiro. Muna 1995, yakasimwa kune GB5310 uye yakanzi 25MnG. Chimiro chayo chemakemikari chiri nyore, kunze kwepamusoro kabhoni uye manganese zvinyorwa, zvakasara zvakafanana ne20G, saka simba regoho rinenge 20% yakakwirira kupfuura 20G, uye plastiki uye kuoma kwakafanana ne20G. Nzira yekugadzira yesimbi iri nyore uye inotonhora uye inopisa kushanda kwayo kwakanaka. Kuishandisa panzvimbo ye20G, kunogona kuderedza kukora kwemadziro, kuderedza kuwanda kwezvinhu, asiwo kunogona kuvandudza kupisa kwekushisa kwebhailer. Zvikamu zvekushandisa uye tembiricha yekushandisa zvakangofanana ne20G, inonyanya kushandiswa pakushanda tembiricha iri pasi pe500 ℃ madziro emvura, economizer, yakaderera tembiricha superheater uye zvimwe zvikamu.
Sa-106c: Inhamba yesimbi mukatiASME SA-106standard. Iyo kabhoni-manganese simbi chubhu kune yakakwirira-tembiricha yakakura-dhayamita boilers uye superheaters. Chimiro chayo chemakemikari chiri nyore, chakafanana ne20G carbon steel, asi zvinyorwa zvekabhoni uye manganese zvakakwirira, saka simba rayo regoho rinenge 12% yakakwirira kudarika 20G, uye plastiki, kuoma hakuna kuipa. Nzira yekugadzira yesimbi iri nyore uye inotonhora uye inopisa kushanda kwayo kwakanaka. Kuishandisa pachinzvimbo che20G yekugadzira muunganidzi (economizer, mvura inotonhorera madziro, yakaderera tembiricha superheater uye reheater coupling bhokisi), ukobvu hwemadziro hunogona kuderedzwa neanosvika gumi muzana, izvo zvisingangogone kuchengetedza mutengo wezvinhu, asi zvakare kuderedza welding basa, uye uvandudze kusiyana kwekunetseka apo bhokisi rekubatanidza rinotanga.
15Mo3 (15MoG) : Iri pombi yesimbi muDIN17175 chiyero. Iyo idiki dhayamita kabhoni molybdenum simbi chubhu ye boiler uye superheater, uye pearlescent mhando inopisa simba simbi. Muna 1995, yakasimwa kune GB5310 uye yakanzi 15MoG. Mushonga wayo wemakemikari uri nyore, asi une molybdenum, saka une simba rinopisa riri nani pane kabhoni simbi uku uchichengeta maitiro akafanana nekabhoni simbi. Nekuda kwekuita kwayo kwakanaka, mutengo wakachipa, wakashandiswa zvakanyanya munyika. Zvisinei, simbi ine tsika ye graphitization mushure mekushanda kwenguva refu pakupisa kwepamusoro, saka kupisa kwayo kwekushanda kunofanira kudzorwa pasi pe510 ℃, uye huwandu hweAl hunowedzerwa mukunyunguduka hunofanira kugumira kudzora uye kunonoka graphitization process. Iyi chubhu yesimbi inonyanya kushandiswa kune yakaderera tembiricha superheater uye yakaderera tembiricha reheater. Tembiricha yemadziro iri pasi pe510 ℃. Mushonga wayo wemakemikari C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Yakajairika simba nhanho σs≥270-285, σb≥450-600 MPa; Plastic delta 22 kana kupfuura.
