20G:GB5310-95 ukwamkelwa kwentsimbi esemgangathweni (ibakala elihambelanayo langaphandle: i-ST45.8 yaseJamani, i-STB42 yaseJapan, i-United States SA106B), yeyona mbhobho yensimbi yebhoyila isetyenziswa ngokuqhelekileyo, ukubunjwa kweekhemikhali kunye neempawu zoomatshini kunye ne-20 plate iyafana. Intsimbi inamandla athile kwiqondo lokushisa eliphakathi kunye nobushushu obuphakathi, umxholo wekhabhoni ephantsi, iplastiki engcono kunye nokuqina, ukubunjwa kwayo okutshisa kunye nokubandayo kunye nokusebenza kwe-welding kulungile. Isetyenziswa ikakhulu kukwenziwa koxinzelelo oluphezulu kunye neeparamitha eziphezulu zofakelo lwebhoyila, icandelo lobushushu eliphantsi le-superheater, i-reheater, i-economizer kunye nodonga lwamanzi, njl njl. Njengombhobho omncinci weqondo lobushushu eludongeni ≤500℃ umbhobho womphezulu wokufudumeza, kunye nombhobho wodonga lwamanzi, ityhubhu ye-economizer, ubushushu bodonga lombhobho omkhulu ≤450℃ umbhobho womphunga, ibhokisi yokuqokelela (i-economizer, udonga lwamanzi, ubushushu obuphantsi be-superheater kunye nebhokisi yokudibanisa i-reheater), ubushushu obuphakathi ≤450℃ izincedisi zemibhobho. Ngenxa yokuba i-carbon steel iya kuvelisa i-graphitization kwixesha elide lokusebenza ngaphezu kwe-450 ℃, ngoko ke ubushushu benkonzo yexesha elide lombhobho wokufudumeza umphezulu bungcono kunokunciphisa ngaphantsi kwe-450 ℃. Intsimbi kolu luhlu lobushushu, amandla ayo anokufikelela kwiimfuno ze-superheater kunye nombhobho womphunga, kwaye inokumelana ne-oxidation elungileyo, iplastiki, ukuqina, iipropati ze-welding kunye nezinye iipropati ezibandayo kunye nezishushu zokulungisa zilungile kakhulu, zisetyenziswa ngokubanzi. Amacandelo entsimbi esetyenziswe kwiziko lase-Iranian (ebhekisela kwiseti enye) ngumbhobho wokungena kwamanzi (iitoni ezingama-28), umbhobho wokungena kwamanzi (iitoni ezingama-20), umbhobho wokudibanisa umphunga (iitoni ezingama-26), isitya se-economizer (8). iitoni), kunye nenkqubo yokunciphisa amanzi (iitoni ezi-5), kwaye ezinye zisetyenziswa njengentsimbi eyisicaba kunye nezixhobo zederrick (malunga neetoni ezingama-86).

Sa-210c (25MnG) : Inombolo yentsimbi ngaphakathiASME SA-210umgangatho. Yityhubhu encinci ye-diameter yentsimbi ye-carbon manganese yeebhoilers kunye ne-superheaters, kunye nentsimbi eshushu eshushu enepearl shape. Kwi-1995, yatshintshelwa kwi-GB5310 kwaye yabizwa ngokuba yi-25MnG. Ukubunjwa kwayo kweekhemikhali kulula, ngaphandle kwekhabhoni ephezulu kunye ne-manganese umxholo, ezinye zifana ne-20G, ngoko amandla okuvelisa amalunga ne-20% ephezulu kune-20G, kwaye iplastiki kunye nokuqina kufana ne-20G. Inkqubo yokuvelisa intsimbi ilula kwaye ukusebenza kwayo okubandayo nokutshisayo kusebenza kakuhle. Ukuyisebenzisa endaweni ye-20G, kunokunciphisa ubukhulu bodonga, ukunciphisa inani lezinto eziphathekayo, kodwa kunokuphucula ukuhanjiswa kobushushu kwibhoyila. Amalungu okusetyenziswa kwawo kunye nobushushu bokusebenzisa ngokusisiseko buyafana ne-20G, ikakhulu isetyenziselwa ubushushu bokusebenza obungaphantsi kwe-500 ℃ yodonga lwamanzi, i-economizer, i-superheater ephantsi kunye nezinye izinto.
Sa-106c: Yinombolo yentsimbi kuyoI-ASME SA-106umgangatho. Yityhubhu yentsimbi ye-carbon-manganese yobushushu obuphezulu bebhoyila ezinobubanzi obukhulu kunye nezifudumezi ezinkulu. Ukubunjwa kwayo kweekhemikhali kulula, kufana ne-20G yensimbi ye-carbon, kodwa umxholo wekhabhoni kunye ne-manganese uphezulu, ngoko amandla ayo okuvelisa malunga ne-12% ephezulu kune-20G, kunye neplastiki, ukuqina akubi. Inkqubo yokuvelisa intsimbi ilula kwaye ukusebenza kwayo okubandayo nokutshisayo kusebenza kakuhle. Ukusebenzisa endaweni ye-20G umqokeleli wokuvelisa (i-economizer, udonga lokupholisa amanzi, i-superheater ephantsi yokushisa kunye nebhokisi yokudibanisa i-reheater), ubukhulu bodonga bungancitshiswa malunga ne-10%, engakwazi ukugcina kuphela iindleko zezinto eziphathekayo, kodwa nokunciphisa umthwalo wokuwelda, kwaye uphucule umahluko woxinzelelo xa ibhokisi yokudibanisa iqala.
15Mo3 (15MoG) : Ingumbhobho wensimbi kwi-DIN17175 standard. Yityhubhu yentsimbi ye-carbon molybdenum enedayamitha encinci yebhoyila kunye ne-superheater, kunye ne-pearlescent yohlobo lwentsimbi eshushu. Kwi-1995, yatshintshelwa kwi-GB5310 kwaye yabizwa ngokuba yi-15MoG. Ukubunjwa kwayo kweekhemikhali kulula, kodwa iqulethe i-molybdenum, ngoko inamandla angcono e-thermal kune-carbon steel ngelixa igcina ukusebenza kwenkqubo efanayo njenge-carbon steel. Ngenxa yokusebenza kwayo kakuhle, ixabiso eliphantsi, lisetyenziswa kakhulu ehlabathini. Nangona kunjalo, insimbi inomkhuba wokwenza i-graphitization emva kokusebenza kwexesha elide kwiqondo lokushisa eliphezulu, ngoko ukushisa kwayo kufuneka kulawulwe ngaphantsi kwe-510 ℃, kwaye inani le-Al elongezelelweyo kwi-smelting kufuneka lilinganiselwe ukulawula nokulibazisa inkqubo ye-graphitization. Le ityhubhu yentsimbi isetyenziselwa ikakhulu ubushushu obuphantsi be-superheater kunye ne-reheater ephantsi yobushushu. Ubushushu bodonga bungaphantsi kwe-510℃. Ukubunjwa kwayo kweekhemikhali C0.12-0.20, SI0.10-0.35, MN0.40-0.80, S≤0.035, P≤0.035, MO0.25-0.35; Umgangatho wamandla oqhelekileyo σs≥270-285, σb≥450-600 MPa; Plastic delta 22 okanye ngaphezulu.
