GB5310ndi code yokhazikika ya dziko la China "Seamless Steel Pipes forMaboiler a High Pressure", yomwe imatchula zofunikira zaumisiri zamapaipi achitsulo osasunthika kwa ma boiler othamanga kwambiri komanso mapaipi a nthunzi. Muyezo wa GB5310 umakwirira mitundu yosiyanasiyana yazitsulo kuti ikwaniritse zosowa zosiyanasiyana zofunsira. Izi ndi zina zodziwika bwino komanso mafakitale awo ogwiritsira ntchito:

20G: 20G ndi imodzi mwamagiredi omwe amagwiritsidwa ntchito kwambiri mu GB5310, yokhala ndi zigawo zazikulu za kaboni, manganese ndi silicon.Ili ndi zida zabwino zamakina komanso zowotcherera, ndipo imagwiritsidwa ntchito makamaka popanga zida zazikulu monga makoma oziziritsa ndi madzi, ma superheaters, economizers ndi ng'oma muma boiler opangira magetsi.

15CrMoG: Chitsulo ichi chili ndi chromium ndi molybdenum, ndipo chimakhala ndi mphamvu zotentha kwambiri komanso kukana kwa okosijeni.15CrMoG mapaipi achitsulo osasunthika nthawi zambiri amagwiritsidwa ntchito popanga mapaipi otenthetsera kwambiri komanso othamanga kwambiri, mitu ndi ma conduits, ndi zina zambiri, ndipo amagwiritsidwa ntchito kwambiri m'mafakitale a petrochemical ndi magetsi.

12Cr1MoVG: Ili ndi chromium yokwera, molybdenum ndi vanadium, yokhala ndi kutentha kwambiri komanso kukhazikika kwanthawi yayitali.Mapaipi achitsulo osasunthika a kalasi iyi nthawi zambiri amagwiritsidwa ntchito pama boiler otentha kwambiri komanso othamanga kwambiri komanso zida zamagetsi za nyukiliya, makamaka osinthanitsa kutentha, mapaipi a nthunzi, ndi zina zambiri.

Mitundu yosiyanasiyana ya mipope yachitsulo yosasunthika imagwiritsidwa ntchito kwambiri popanga zigawo zazikuluzikulu zotentha kwambiri komanso zopanikizika kwambiri monga mphamvu, petrochemical, ndi mphamvu ya nyukiliya chifukwa cha kapangidwe kake kake kapadera komanso makina.Posankha kalasi yoyenera yachitsulo, chitetezo ndi kukhazikika kwa zipangizo pansi pazigawo zogwira ntchito kwambiri zingathe kutsimikiziridwa, ndipo moyo wautumiki ukhoza kukulitsidwa.
